Checkbox for auto generated columns

Question

Hi,

I have tried to implement checkboxes to Grid with auto generated columns.By doing it like this:     this.tableService.model$.subscribe((x) => {      x.map((y) => (y['checkbox'] = false));    });and :if ((cols as any).field === 'checkbox')     {            cols['type'] = 'checkbox';     }And I have defined the datasource as such.[dataSource]="tableService.model$ | async"But the unselect doesn't work and the "Select/Unselect All" doesn't update.

Hi Gustav,  Greetings from
Syncfusion support.  Based on your query,
you want to add a checkbox column along with the autogenerated columns.  Your requirements can be achieved by using
the dataBound event of the EJ2 Grid.Refer the below code example.

dataBound(args) {
      if (this.addColumn) {
        var obj = { type: 'checkbox', width: 50 };
        this.grid.columns.unshift(obj as any);
        this.addColumn = false;
        this.grid.freezeRefresh();
      }
    }
