Grid appears to be partially freezing - ag-grid

Using the release 16.0.0 of the enterprise ag-grid.
When I first start the website, I am able to load the grid and the row click and double click events fire.
When i reload (the grid with new data, the grid does not respond to the click or double click event BUT i am able to set focus to the grid, and move around the grid using the arrow keys.
Here is my gridOptions
var gridOptions = {
columnDefs: columnDefs,
enableColResize: true,
enableSorting: true,
rowSelection: 'single',
getMainMenuItems: getMainMenuItems,
getContextMenuItems: getContextMenuItems,
allowContextMenuWithControlKey: true,
popupParent: document.querySelector('body'),
onGridReady: function (params) {
},
onRowDoubleClicked: function (params) {
popupCard(params.node.data.cardID);
},
onRowClicked: function (params) {
popupCard(params.node.data.cardID);
}
};
As mentioned, I am able to navigate after the data reload using the arrow keys, but the click and double click do not seem to fire.
Any ideas?

If you have defined the functions inside class then you might need to use
onRowClicked: function (params) {
this.popupCard(params.node.data.cardID);
}

ag-Grid Master / Detail - Row Selection

Goals
I am trying to add row selection functionality which is connected between the master grid and detail grid.
When a checkbox on a master grid row is selected, I want to select all the checkboxes in the associated detail grid.
When a checkbox on a master grid row is deselected, I want to deselect all the checkboxes in the associated detail grid.
When only partial checkboxes inside of a detail grid are selected, I want the master grid row to show a partial selection icon in the checkbox.
I want to keep count of how many items were selected in all of the detail grids
Questions/Problems
All of this functionality already exists for Groups, but I cannot get it to work for Master/Detail. I've tried adding in the line that I believe should add this for Groups cellRendererParams: {checkbox: true}, but that does nothing for the detail grid.
I've also tried implementing the functionality myself, but I hit a couple of roadblocks.
I don't know how to set the partial-checkbox icon manually or if that's even possible.
I implemented the onSelectionChanged event handler for the detail grid, but inside of the function it looks like I can't access the Angular component context to update the count of selected items. Not sure how to pass in the context this.
Code that I have working so far:
When a checkbox on a master grid is selected/deselected, the checkboxes in the associated detail grid are all selected/deselected.
public onMasterRowSelected() {
this.gridOptions.api.forEachNode(masterRowNode => {
if(masterRowNode.isSelected()) {
this.gridOptions.api.getDetailGridInfo(`detail_${masterRowNode.id}`).api.selectAll();
} else {
this.gridOptions.api.getDetailGridInfo(`detail_${masterRowNode.id}`).api.forEachNode(detailRowNode => detailRowNode.setSelected(false));
}
});
}
Added the onSelectionChanged() event listener for the detail grid.
constructor() {
this.gridOptions = {
...
detailCellRendererParams: {
getDetailRowData: function(params) {
params.successCallback(params.data.items); // Defines where to find the detail fields out of the rowData object
},
detailGridOptions: {
rowSelection: 'multiple',
defaultColDef: {
sortable: true
},
getRowNodeId: function (rowData) {
return rowData.id; // detail items are indexed by id field
},
onSelectionChanged: function (params) {
console.log(this); // I expected this to print out my Angular component object, but instead it prints out this.gridOptions.detailCellRendererParams.detailGridOptions
console.log("TEST"); // I know that this function is successfully being called because this line is printed
this.selectedItems = 0;
params.api.forEachNode(detailRowNode => {
if(detailRowNode.isSelected()) {
this.selectedObs++; // I believe that this would work if I had access to the correct "this" context
}
});
},
columnDefs: [
{headerName: 'Column 1', field: 'column1', checkboxSelection: true},
{headerName: 'Column 2', field: 'column2'},
]
}
}
};
}
Here is an Angular example where you can push the parent component as a reference to the detail grid and set it as its context. Doing this allows you to register a component method as a callback for the detail grid's onRowSelected method.
https://stackblitz.com/edit/ag-grid-detailrow-selectcallback?file=src/app/app.component.ts
Move the onSelectionChanged(params) function to the same level as the detailCellRendererParams object.
internalOnSelectionChanged(params)
{
this.detailGridApi = params.api;
this.detailGridColumnApi = params.columnApi;
console.log(this);
}
Then, on the onSelectionChanged, do this:
onSelectionChanged: this.internalOnSelectionChanged.bind(this);
This solved my issues that were very similar to yours.

Ag-Grid Prevent tree expand/collapse when double clicking on cell

I have some code in my grid where I'm trying to prevent a double-click event from causing a tree row to expand/collapse and I can't find documentation how to do this anywhere. The reason I want to do this is so that when I double click the cell, I want to make it editable, but due to some technical necessities, I need to run gridApi.redrawRows() when the collapse/expand happens which causes the edit field to lose focus, meaning I can never actually edit the cell by double clicking.
I'm using the following ag-grid module versions
"ag-grid-angular": "^22.1.1",
"ag-grid-community": "^22.1.1",
"ag-grid-enterprise": "^22.1.1"
And the relevant html in my grid looks like this
<ag-grid-angular
#agGrid
class="ag-theme-balham"
[modules]="modules"
[columnDefs]="columnDefs"
[rowData]="rowData"
[treeData]="true"
(rowGroupOpened)="onRowGroupOpened($event)"
(cellDoubleClicked)="handleCellDoubleClicked($event)"
[getDataPath]="getDataPath"
[defaultColDef]="defaultColDef"
[frameworkComponents]="frameworkComponents"
[autoGroupColumnDef]="autoGroupColumnDef"
(gridReady)="onGridReady($event)"
[getRowNodeId]="getRowNodeId"
>
</ag-grid-angular>
In my component file, the particular column that is responsible for auto grouping the rows in a tree-format looks like this
ngOnInit() {
this.autoGroupColumnDef = {
editable: this.isAllowedtoEdit,
headerName: "Account #",
sortable: true,
lockPosition: true,
resizable: true,
field: "accountNum",
filter: "agGroupCellRenderer",
cellRendererParams: {
suppressCount: true,
innerRenderer: 'AccountNameColumnDisplayer',
},
};
}
And the function for handling the double click on a cell is this:
handleCellDoubleClicked(cell) {
if(cell.column.colDef.field === 'accountNum') {
cell.event.stopPropagation();
return false;
}
}
My handleCellDoubleClicked() function doesn't seem to do anything. It runs but the row still expands/collapses when I double click.
I even tried this just to see what it would do and it was causing some really weird behaviors to happen
handleCellDoubleClicked(cell) {
if(cell.column.colDef.field === 'accountNum') {
cell.node.setExpanded(false)
}
}
And finally, when I try to focus on
handleCellDoubleClicked(cell) {
if(cell.column.colDef.field === 'accountNum') {
setTimeout(() => {
this.gridApi.startEditingCell({
rowIndex: node.rowIndex,
colKey: 'accountNum'
});
}, 125);
}
}
I get a warning in the console telling me that ag-grid does not recognize the column accountNum
So I'm at a bit of a loss right now. Is there something I can do? Thanks in advance!
You should be able to add the following property to your cellRendererParams to achieve this:
cellRendererParams: {
...yourOtherParams,
suppressDoubleClickExpand: true
}
Cheers!

Switch between editable and non editable mode in ag-grid

I am using ag-grid to display and modify data.How Can I switch between editable and non editable for the hole ag-grid. Can I do this with the grid api.
this is my default config:
this.defaultDefs = {
suppressMovable: true,
enableColResize: true,
editable: true,
};
Can I change editable dynamically?
editable can be either a boolean as you have it, or a function
If you use the function form you can determine on a cell by cell basis if you want the given cell to be editable
editable: function(params) {
return true; // true/false based on params (or some other criteria) value
}
you can set editable property by your way just create another function isEditable(columnName) which will give you boolean result.
this.defaultDefs = {
suppressMovable: true,
enableColResize: true,
editable: isEditable(column),
};
Do a logic check in the cellEditingStarted callback, calling the stop() when the check fails. You may need to write some css to style it or add a toast/notification to give the user feedback on why they're not able to edit.
You can use it like this:
editable: (params) => your logic
update your date
call api.redrawRows({ rowNodes: [node] })
You can also use suppressClickEdit in the grid options for a quick disabling:
gridOptions: {
suppressClickEdit: true | false,
...
}
See: https://www.ag-grid.com/angular-data-grid/cell-editing-start-stop/#no-click-editing
A simpler approach
editable: (params:any)=> params.data.isEdit === 'edit' ? true : false
add it to the columndefinitions
*
Note: isEdit === 'edit' is your custom logic

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.

Bind event to right-click

How do I bind to or recognize a right-click event?
I have a scatter plot where left-click adds a point at the clicked location; I would like right-click to remove the point (if present).
This is my current code:
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
events: {
click: function(event) {
var cs = [Math.floor(event.xAxis[0].value),
Math.floor(event.yAxis[0].value)];
this.series[0].addPoint(cs);
}
},
type: 'scatter',
},
... etc. ...
});
This should help:Making Highcharts support right click context menu
This is not a full solution: I did not figure out how to capture right-click events.
But here's a workaround for clicking on the chart background:
have the user do a shift-click
supply a callback as before
in the callback, inspect the event. If shift was pressed, do something different
Here's what the callback might look like:
function clickChart(event) {
var isShiftPressed = event.shiftKey;
if(isShiftPressed) {
// do something
} else {
// do something different
}
The event object has boolean attributes shiftKey (and altKey).
Here's a workaround for removing points: (actually, it's not a workaround -- I just didn't realize there was an easier way!)
points have their own events
just set up a callback that removes points when they're clicked
Example:
function clickPoint(event) {
this.remove();
}
var chart = new Highcharts.Chart({
chart: {
type: 'scatter',
renderTo: 'chart',
},
series: [{
point: {
events: {
click: clickPoint
}
}
}]
});
Note: the documentation is misleading, at the least, but the jsfiddle examples seem to be correct. It seems to show that the point options are not in series.
Currently, there are only a few events supported by Highcharts.
for ref : https://www.highcharts.com/blog/tutorials/introduction-to-highcharts-events/
To add custom events, such as
double click (including mobile devices)
right click (context menu)
mouse over
mouse out
mouse down
mouse move
we can add a plugin
highcharts-custom-events
https://www.npmjs.com/package/highcharts-custom-events
hope you find this helpful and solves your problem.
