How to disable row group expand functionality on one row? - ag-grid

After a lot of searches in SO without any particular solution, I am compelled to ask this question.
What I want is to hide a row group icon on a single group row. Like in the below picture I have a group row that has only one record, which is already shown in the top row. I want to hide that collapse icon on that single record. Only collapse/expand icon shown when group rows are more than one.
For reference see AG-Grid Master-Detail Section, here they specify which rows to expand. Same functionality I needed here.
I'm using the below versions of AG-Grid Angular (v9)
"#ag-grid-community/core": "^25.3.0",
"#ag-grid-enterprise/row-grouping": "^26.0.0",
"#ag-grid-enterprise/server-side-row-model": "^25.3.0",
"ag-grid-angular": "^25.3.0",
"ag-grid-community": "^25.3.0",
Here is my code:
this.rowModelType = 'serverSide';
this.serverSideStoreType = 'partial';
this.cacheBlockSize = 20;
this.gridOptions = {
rowData: this.loanlist,
columnDefs: this.generateColumns(),
getNodeChildDetails: function(rowItem) {
if (rowItem.orderCount > 1) {
return {
expanded: true
}
} else {
return null;
}
}
}
The issue is the getNodeChildDetails is not accessible. Browser console showing me the below warning and my above code is not working.

This is simple to achieve using a cellRendererSelector on the autoGroupColumnDef. You can specify whether to show the default agGroupCellRenderer or simply return another renderer (or, just return null):
this.autoGroupColumnDef = {
cellRendererSelector: (params) => {
if (params.value == 'United States') {
return null;
} else {
return {
component: 'agGroupCellRenderer',
};
}
},
};
In the example below, we are disabling the row group expand functionality on the United States row.
See this implemented in the following plunkr.

The solution isn't that hard - but could be tough, agreed (one day faced with the same case)
So - the answer is custom cell renderer.
It would look a little bit different (separate column for collapse\expande action) - but you would get all control of it.
Custom rendeder component for this action would look like :
template: `
<em
[ngClass]="{'icon-arrow-down':params.node.expanded, 'icon-arrow-right': !params.node.expanded}"
*ngIf="yourFunctionHere()"
(click)="toggleClick()">
</em>`,
export class MasterDetailActionComponent implements ICellRendererAngularComp {
private params: any;
agInit(params: any): void {
this.params = params;
}
public toggleClick(): void {
this.params.node.setExpanded(!this.params.node.expanded);
}
public yourFunctionHere(): boolean {
// so here you are able to access grid api via params.api
// but anyway params.node - would give you everything related to row also
}
refresh(): boolean {
return false;
}
}
in [ngClass] - you are able to handle the visual part (icons) - modify\customize
and don't forget to add this component in the gridOptions:
frameworkComponents: {
'masterDetailActionCellRenderer': MasterDetailActionComponent,
}
and include this column in your columnDef:
columnDefs: [
headerName: "",
width: 75,
field: "expand",
cellRenderer: "masterDetailActionCellRenderer",
filter: false,
resizable: true,
suppressMenu: true,
sortable: false,
suppressMovable: false,
lockVisible: true,
getQuickFilterText: (params) => { return '' }
]

How add menu button to ag-Grid row?

I'm using ag-Grid Enterprise Vue.
I see in the docs how to enable a "context menu" that is available by right-clicking any individual cell.
I instead would love to have a special column (pinned to the right) that has a button (maybe looking like ⚙ or ...) that opens a menu upon left-click.
How could I go about enabling this? I have found no examples in the docs.
Ag-grid Cell containing menu button is a similar question but has no answer.
From this comment on this ag-grid-enterprise issue, I was able to fork the example, and I think it will work for my situation.
The relevant code is:
var gridOptions = {
columnDefs: columnDefs,
enableRangeSelection: true,
getContextMenuItems: getContextMenuItems,
allowContextMenuWithControlKey: true,
onCellClicked: params => {
console.log(params);
if(params.column.colDef.field === '...'){
params.api.contextMenuFactory.showMenu(params.node, params.column, params.value, params.event)
}
},
onCellContextMenu: params => {
params.api.contextMenuFactory.hideActiveMenu()
}
};
function getContextMenuItems(params) {
console.log('getContextMenuItems', params);
const node = params.node;
console.log('node.id, node.rowIndex, node.data', node.id, node.rowIndex, node.data);
var result = [
{
name: `Alert 'Row ${node.rowIndex + 1}'`,
action: function() {
window.alert(`Row ${node.rowIndex + 1}`);
},
cssClasses: ['redFont', 'bold']
},
'separator',
{
name: 'Checked',
checked: true,
action: function() {
console.log('Checked Selected');
},
icon: '<img src="../images/skills/mac.png"/>'
},
'copy' // built in copy item
];
return result;
}

agGrid with Angular, using agRichSelectCellEditor

I have an agGrid populated with Employee records in JSON format from my web service.
[
{
id: 123,
firstName: 'Mike',
lastName: 'Jones',
countryId: 1001,
DOB: '1980-01-01T00:00:00',
. . .
}
I have a second web service returning a list of country codes:
[
{ id: 1000, name: 'France' },
{ id: 1001, name: 'Spain' },
{ id: 1002, name: 'Belguim' }
]
What I'm trying to do is get my agGrid to have a column showing the user's details, including the name of their country, and when they edit this cell, a list of country codes will appear, where they can select one, and it'll update the record with the id of that country.
Basic stuff, no ?
But has anyone managed to get agGrid to successfully use the "agRichSelectCellEditor" to do this successfully ?
{ headerName: 'Country', width: 120, field: 'countryId', editable: true,
cellEditor:'agRichSelectCellEditor',
cellEditorParams: {
// This tells agGrid that when we edit the country cell, we want a popup to be displayed
// showing (just) the names of the countries in our reference data
values: listOfCountries.map(s => s.name)
},
// The "cellRenderer" tells agGrid to display the country name in each row, rather than the
// numeric countryId value
cellRenderer: (params) => listOfCountries.find(refData => refData.id == params.data.countryId)?.name,
valueSetter: function(params) {
// When we select a value from our drop down list, this function will make sure
// that our row's record receives the "id" (not the text value) of the chosen selection.
params.data.countryId = listOfCountries.find(refData => refData.name == params.newValue)?.id;
return true;
}
},
My code seems to be almost correct.. it manages to:
display the country name in each row of the agGrid
display a popup, listing the country names, from our "list of countries" array
when I select an item in the popup, it successfully updates the countryId field with the (numeric) id value of my chosen country
The only problem is that at the top of the popup, it shows the countryId value, rather than the user's current country name.
Has anyone managed to get this to work ?
The only workaround I could come up with was to override the CSS on this popup and hide that top element:
.ag-rich-select-value
{
display: none !important;
}
It works... but you no longer get to see what your previously selected value was.
(I really wish the agGrid website had some decent, real-life, working Angular examples... or at least let developers post comments on there, to help each other out.)
The solution was to use a valueGetter, rather than a cellRenderer:
{
headerName: 'Country', width: 120, field: 'countryId', editable: true,
cellEditor:'agRichSelectCellEditor',
cellEditorParams: {
// This tells agGrid that when we edit the country cell, we want a popup to be displayed
// showing (just) the names of the countries in our reference data
values: listOfCountries.map(s => s.name)
},
valueSetter: function(params) {
// When we select a value from our drop down list, this function will make sure
// that our row's record receives the "id" (not the text value) of the chosen selection.
params.data.countryId = listOfCountries.find(refData => refData.name == params.newValue)?.id;
return true;
},
valueGetter: function(params) {
// We don't want to display the raw "countryId" value.. we actually want
// the "Country Name" string for that id.
return listOfCountries.find(refData => refData.id == params.data.countryId)?.name;
}
},
I hope this is useful...
I was able to get my similar situation (id:name pairs in a list, but not using Angular though) working without the problem you mentioned above, and without a valueGetter/valueSetter and only a renderer. The benefit is that you don't need to double click the cell to see the list, the cell appears as a selection box always, and you avoid a bug should the user double click the cell when the list is displayed.
The renderer is a lot clunkier than I was wanting (one line like yours) and it didn't seem that aggrid had built in support for this pretty basic function (and I already have spent enough time on this).
Anyway, this is what I had, which at least works, but keen to see further improvements on it. (You will need to at least change 2 lines for the option related code since my defaultValue object is specific to me).
The column definition:
{field: 'defaultValueID', headerName: "Default Value", cellEditor:'agRichSelectCellEditor', cellRenderer: defaultValueRenderer}
And the renderer code:
function defaultValueRenderer(params) {
var input = document.createElement("select");
// allow it to be cleared
var option = document.createElement("option");
option.innerHTML = '[None]';
option.value = null;
input.appendChild(option);
for (var i=0; i < defaultValueList.length; i++) {
var option = document.createElement("option");
option.innerHTML = defaultValueList[i].name;
option.value = defaultValueList[i].gltID;
input.appendChild(option);
}
input.value = params.value;
input.onchange = function() {
params.setValue(this.value);
params.data.defaultValueID = this.value;
}
input.style="width: 100%; height: 100%"; // default looks too small
return input;
}
Here Is Example Of agRichSelectCellEditor...
{
headerName: 'Dropdown', field: 'dropdown',
cellEditor: 'agRichSelectCellEditor',
width: 140,
editable: true,
cellEditorParams: (params) => {
values: Get All Dropdown List Like ["Hello","Hiii","How Are You?"]
},
valueSetter: (params) => {
if (params.newValue) {
params.data.dropdown= params.newValue;
return true;
}
return false;
}
}
Much simpler solution: use cellEditorParams formatValue, along with valueFormatter
{
field: 'foo',
cellEditor: 'agRichSelectCellEditor',
cellEditorParams: {
values: [1,2,3, 4, other ids... ],
formatValue: (id: number): string => this.getLabelFromId(value)
},
valueFormatter: (params: ValueFormatterParams): string => this.getLabelFromId(params.value as number)
}

ag-grid: call function every time filter is clicked

How to call a function every time the filter icon is clicked in ag-grid. Below is my code. My aim is to reset the filter values of Name column every time filter icon is clicked. I have to use agSetColumnFilter. I tried filterParams but it is not called every time but only ones Can anyone please guide me here?
constructor(private http: HttpClient) {
this.columnDefs = [
{
headerName: "Name",
field: "name",
width: 150,
filter: "agSetColumnFilter",
menuTabs: ['filterMenuTab']
}
];
}
onGridReady(params) {
this.rowData = [
{
name: "A",
flag: true
},
{
name: "B",
flag: false
}
];
}
You can use the postProcessPopup callback (see documentation here). This callback is called every time you click on the filter icon.
Add your callback into your html:
[postProcessPopup]="postProcessPopup"
Then create your postProcessPopup function:
this.postProcessPopup = function(params) {
if (params.column.colDef.field === 'name')
{
var athleteFilter = this.gridApi.getFilterInstance('name');
athleteFilter.selectEverything();
this.gridApi.onFilterChanged();
}
}.bind(this);
If the click filter icon is for the field name, then selecting everything for that filter, then call the onFilterChanged function on the gridApi to make sure it updates.
You can see a working Plunker here (try filtering the "Athelete" field).
More documentation on the filter api can be found here.

Is it possible to have own custom Context Menu in ag-Grid-community

Can't find the exact answer.
If i decide to opt-in for vanilla JavaScript (non-Angular & Co) ag-Grid-community edition, can i have easy to add my own custom context menu an other custom extensions?
As i seen their docs, context menu is only enterprise level feature.
I seen some treads that there is some caveats, but i personally did not dig deeper.
In general, how easy is to implement self-built features in ag-Grid-community. Or it is better to write own grid?
We have a custom context menu component in our Angular project with ag-grid community, so it's definitely possible.
How it works:
We define all grid columns in templates. If you want a context menu, you put an empty column into the column set and put a special directive on it. The directive accepts a context menu template, which is passed into a custom cellRendererFramework (a menu trigger button, basically). The directive also configures the column to ensure consistent look across grid instances.
This might be not what you've been looking for if you require for menu to open with right mouse click anywhere in a row, but I suppose it shouldn't be that hard to trigger the menu from a different event (check out ag-grid events, there might something suitable).
The snippets below should be straightforward to adapt for your framework of choice. Given you opted into vanilla JS, you'll have to use regular functions to do the same, something like this:
const grid = withContextMenu(new Grid(element, gridOptions), menuOptions).
Here's an example of how we use it:
<ag-grid-angular>
<ag-grid-column headerName='ID' field='id'></ag-grid-column>
<ag-grid-column [contextMenu]='menu'>
<mat-menu #menu='matMenu'>
<ng-template matMenuContent let-item='data'>
<button mat-menu-item (click)='restoreSnapshot(item.id)'>Restore From Snapshot</button>
<a mat-menu-item [routerLink]='[item.id, "remove"]'>Remove</a>
</ng-template>
</mat-menu>
</ag-grid-column>
</ag-grid-angular>
The directive that applies the menu:
const WIDTH = 42;
export const CONTEXT_MENU_COLID = 'context-menu';
#Directive({
selector: '[agGridContextMenu]'
})
export class AgGridContextMenuDirective implements AfterViewInit {
constructor(private gridComponent: AgGridAngular) {}
#Input()
agGridContextMenu!: ElementRef<MatMenu>;
ngAfterViewInit() {
if (!this.agGridContextMenu) return;
setTimeout(() => {
this.gridComponent.api.setColumnDefs([
...this.gridComponent.columnDefs,
{
colId: CONTEXT_MENU_COLID,
cellRendererFramework: CellRendererContextMenuComponent,
width: WIDTH,
maxWidth: WIDTH,
minWidth: WIDTH,
cellStyle: {padding: 0},
pinned: 'right',
resizable: false,
cellRendererParams: {
suppressHide: true,
contextMenu: {
menu: this.agGridContextMenu
}
}
}
]);
});
}
}
The cell renderer component:
#Component({
selector: 'cell-renderer-context-menu',
template: `
<ng-container *ngIf='params.data && params.colDef.cellRendererParams.contextMenu.menu'>
<button
type='button'
mat-icon-button
[matMenuTriggerFor]='params.colDef.cellRendererParams.contextMenu.menu'
[matMenuTriggerData]='{data: params.data}'
>
<mat-icon svgIcon='fas:ellipsis-v'></mat-icon>
</button>
</ng-container>
`,
styleUrls: ['./cell-renderer-context-menu.component.scss']
})
export class CellRendererContextMenuComponent implements ICellRendererAngularComp {
params!: ICellRendererParams;
agInit(params: ICellRendererParams) {
this.params = params;
}
refresh() {
return false;
}
}
A screenshot:
I followed this blogpost, using community edition ag-grid, and it worked! I was surprised because previously I had the experience that cell renderers didn't allow content outside of the cell boundaries to be shown, but somehow popper/tippy is getting around that (I think it adds itself to the top of the DOM with this section of code appendTo: document.body).
https://blog.ag-grid.com/creating-popups-in-ag-grid/
basically, in my javascript CellRenderer:
class MyCellRenderer{
// https://www.ag-grid.com/javascript-data-grid/component-cell-renderer/
init(e){
this.isOpen = false;
this.container = document.createElement("span");
let menubutton = document.createElement("button");
menubutton.innerHTML="&#x1F80B"; //downward arrow
this.tippyInstance = tippy(menubutton);
this.tippyInstance.disable();
this.container.appendChild(menubutton);
menubutton.addEventListener('click', that.togglePopup.bind(this));
}
getGui() {
return this.container;
}
togglePopup() {
this.isOpen = !this.isOpen;
if (this.isOpen) {
this.configureTippyInstance();
this.eMenu = this.createMenuComponent();
this.tippyInstance.setContent(this.eMenu);
} else {
this.tippyInstance.unmount();
}
}
configureTippyInstance() {
this.tippyInstance.enable();
this.tippyInstance.show();
this.tippyInstance.setProps({
trigger: 'manual',
placement: 'bottom-start',
arrow: false,
interactive: true,
appendTo: document.body,
hideOnClick: true,
onShow: (instance) => {
tippy.hideAll({ exclude: instance });
},
onClickOutside: (instance, event) => {
this.isOpen = false;
instance.unmount();
},
});
}
createMenuComponent() {
let menu = document.createElement('div');
menu.classList.add('menu-container');
let options = {};
options['Delete Row'] = this.menuItemClickHandler.bind(this);
options['Popup an Alert!'] = function(){alert("hello!");};
options['Popup an Alert 2!'] = this.menuItemClickHandler.bind(this);
for (const [key, value] of Object.entries(options)) {
let item = document.createElement('div');
item.classList.add('menu-item');
item.setAttribute('data-action', key.toLowerCase());
item.classList.add('hover_changes_color');
item.innerText = `${key}`; // string formatting example
item.addEventListener('click', value);
menu.appendChild(item);
}
return menu;
}
menuItemClickHandler(event) {
this.togglePopup();
const action = event.target.dataset.action;
if (action === 'delete row') {
this.params.api.applyTransaction({ remove: [this.params.data] });
}
if (action === 'popup an alert 2!') {
alert("2");
}
}
}
and in styles.css:
.hover_changes_color:hover {
background-color: dimgrey;
cursor: pointer;
}

how to remove first menu from ag-grid column menu

Is there an option to remove first menu from ag-grid column menu?
I mean the menu with 'pinSubMenu', 'valueAggSubMenu', 'autoSizeThis', etc.
I want to open the context menu and to see first the filter menu and second the columns visibility menu.
I tried to do this, but it still opens empty menu and I need to navigate to my filter menu:
function getMainMenuItems(params) {
var countryMenuItems = [];
var itemsToExclude = [
'separator', 'pinSubMenu', 'valueAggSubMenu', 'autoSizeThis', 'autoSizeAll', 'rowGroup', 'rowUnGroup',
'resetColumns', 'expandAll', 'contractAll','toolPanel'
];
params.defaultItems.forEach(function(item) {
if (itemsToExclude.indexOf(item) < 0) {
countryMenuItems.push(item);
}
});
return countryMenuItems;
}
Looks like you should be able to accomplish what you want to do within the gridOptions:
gridOptions = {
...
suppressMenuMainPanel: true,
...
}
You can also suppress any of the panels of the column menu:
gridOptions = {
...
suppressMenuMainPanel: true,
suppressMenuColumnPanel: true,
suppressMenuFilterPanel: true,
...
}
This is supposing that you are using the Enterprise version, which I assumed you were based on your usage of the getMainMenuItems function
You need to specify menuTabs in the colDef object:
{
headerName: "ID",
field: "id",
menuTabs: ['filterMenuTab','generalMenuTab','columnsMenuTab']
}
See more details here.
