In my Angular application I have a grid that is almost identical to the Group Selection example in the ag-Grid docs: https://www.ag-grid.com/javascript-grid-selection/#gsc.tab=0
My requirement is slightly different in that my expand button needs to both expand the row and select the row. As you see in the plunker example selection and expansion are two separate click events, but I am looking to select the row and expand that same row in one click, without having the user click on the checkbox and the expand button. I have tried doing this with css by making the checkbox transparent and placing it over the expand icon, but the click is highjacked so only one event will fire...
Is this possible in ag-Grid?
In my component by columnDefs for the column that has my checkbox and expand icon looks like so:
...
this.gridOptions.columnDefs = [
{
headerName: '', width: 100, cellRenderer: 'group',
// for parent row selection - checkboxes for parent rows
checkboxSelection: function(params) {
return params.node.canFlower;
},
cellRendererParams: { value: ' ' }, colId: 'PlusIcon', pinned: 'left', cellClass: 'center'
},
...
Listen to the rowGroupOpened event and set the row to selected:
// inside the ag-grid tag
(gridReady)="onGridReady($event)"
// inside the AppComponent class
onGroupOpened(event){
event.node.setSelected(true)
console.log(event)
}

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.
I have an ag-grid where rows are grouped by first column. The group are expanded by default. I want to disable group collapse on click.
colDefs = [{
field: 'colA',
rowGroup: true,
hide: true
}, {
field: 'colB'
},
...
];
gridOptions = {
groupDefaultExpanded: -1,
...
}
How do i prevent from collapsing the group open by default
I guess the colB has a showRowGroup: 'colA' and a cellRenderer: 'agGroupCellRenderer'.
You can remove the cellRenderer from it and it will display the group title as a simple string without showing the collapse icon and without the collapse abililty too.
I managed to do that by adding the following css:.ag-group-expanded {pointer-events: none;}
I also set to true suppressDoubleClickExpand and suppressEnterExpand so there is no way to collapse the rows.
As we can see on https://www.ag-grid.com/javascript-grid-column-menu/, when the user checks/unchecks a column from the menu, the grid animates the other columns.
I'm introducing some columns dynamically, by using columnDefs:
this.columnDefs = [
{ headerName: 'Name', field: 'name', width: 200 },
{ headerName: 'S01F01', hide: this.solver !== 'solver1', field: 'age', width: 90, suppressToolPanel: true },
...
];
I've bound the hide/show flag to buttons on the UI that will bring a set of columns into the grid when needed. Although the columns show up appropriately, they simply appear instead of animating into the grid. I understand this is because I'm simply updating the columnDefs for the whole grid every time the user clicks the button.
Is there a way for me to display these columns on the click of the button while at the same time triggering the animation?
Unless you have this grid property suppressColumnMoveAnimation=true, the columns should have animation on by default.
As per docs
Column animations are on by default, row animations are off by
default. This is to keep with what is expected to be the most common
configuration as default.
I want to have the selection checkbox for ag-grid with the option below:
But didn't see the checkbox on the left. Have any idea what else needs to be settings to make the selection checkbox works.
self.appliancesInGroupGridOpts = {
angularCompileRows: true,
enableColResize : true,
rowData: null,
checkboxSelection: true,
enableSorting: true,
columnDefs: [
{
valueGetter: 'data.name',
headerName: $filter('translate')('APPLIANCE.NAME'),
suppressSizeToFit : true,
template: '<span class="appliance-name">{{data.name}}</span>',
checkboxSelection: true,
width: 200
} ,
{
valueGetter: 'data.updated',
headerName: $filter('translate')('APPLIANCE_GROUP.PUBLISH.MODIFICATION_TIME'),
suppressSizeToFit : true,
template: '<span class="appliance-updated">{{data.updated}}</span>',
checkboxSelection: true,
width: 200
}
] ,
http://www.ag-grid.com/angular-grid-selection/index.php
Checkbox selection can be used in two places:
row selection
group selection.
To include checkbox selection for a column, set the attribute
columnDefs: [{
valueGetter: 'data.name',
headerName: $filter('translate')('APPLIANCE.NAME'),
suppressSizeToFit : true,
template: '<span class="appliance-name">{{data.name}}</span>',
width: 200,
checkboxSelection: true
...
on the column definition.
You can set this attribute on as many columns as you like, however, it doesn't make sense to have it in more one column in a table.
To enable checkbox selection for groups, set the attribute:
groupColumnDef: {
headerName: "Athlete",
field: "athlete",
width: 200,
cellRenderer: {
renderer: "group",
checkbox: true
}
}
for the group renderer. See the grouping section for details on the group renderer.
Selecting groups can have the effect of selecting the group row, or selecting all the children in the group. This is done by setting the attribute:
groupSelectsChildren: {true || false}
When set to false, then selecting the group will select the group node.
When set to true, then selecting the group will either select or deselect all of the children.
The example below shows checkbox selection with groups. Selecting the group has the effect of selecting the children. Likewise selecting all the children automatically selects the group. In this scenario the group itself will never appear in the selectedRows list.
The example also shows a checkbox for selection on the age column. In practice, it is not normal to have more than two columns for selection, the below is just for demonstration. Having a checkbox within a non-group row is best for grids that are not using grouping.
In Addition: you could add this on the col definition
checkboxSelection:
Set to true to render a selection checkbox in the column.
What say einav is true however i think he forgot the very base :
set the property rowSelection:'single' or rowSelection:'multiple' on gridOptions if you want to have selection enabled :)
The attribute checkboxSelection is only for columns not grid options.
The following properties are relevant to selection:
rowSelection: Type of row selection, set to either 'single' or 'multiple' to enable selection.
rowDeselection: Set to true or false. If true, then rows will be deselected if you hold down ctrl + click the row. Normal behaviour with the grid disallows deselection of nodes (ie once a node is selected, it remains selected until another row is selected in it's place).
suppressRowClickSelection: If true, rows won't be selected when clicked. Use, for example, when you want checkbox selection, and don't want to also select when the row is clicked.

I have a grid with two checkcolumns and a text field
{
xtype: 'checkcolumn',
id: 'apprId',
text: '<b>Approve</b>',
width: 100,
dataIndex: 'aprvInd'
},
{
xtype: 'checkcolumn',
id: 'declId',
text: '<b>Decline</b>',
width: 100,
dataIndex: 'declInd'
},
{
id: 'declResnId',
header: '<b>Decline Reasons</b>',
dataIndex: 'declineReason',
align: 'center',
width: 200,
editor: new Ext.form.TextField({
maxLength: 100000
}),
}
if my grid has three rows, first row 'approve' checkbox checked, second row 'decline' checkbox checked and third row nothing checked.
on click of save button, i am doing a rest call and i m passing the data to db, and on success call back , i m reloading grid.
After reloading, the rows which have approve/decline checked should be disabled along with the 'declineReasons' text field.
How can i do this?
If you want to grey out the row I would look at the metaData parameter of the renderer config. Probably the trCls is referenced there.
To disable a checkbox I also would look at the renderer.
To disable the editor plugin look at the beforeedit event.
