To enable the "Select All" functionality in ag-grid's infinite scrolling feature in Angular 4, utilize the header check box

Is there a way to add a checkbox in the header of ag-grid for selecting all options when using an infinite row model? It seems that the headerCheckboxSelection=true feature is not supported in this model.

Are there any alternative methods to include a checkbox inside the header cell?

I plan to trigger a service call upon clicking this checkbox for additional processing.

Below is my current table configuration:

this.columnDefs = [
      {
       headerCheckboxSelection:true
       checkboxSelection: true,
       width: 40,
      },
      {
        headerName: "Date/Time",
        field: "createdDate",
        width: 230
      },
      {headerName: 'File Name', field: 'fileName', width: 240},
      {headerName: 'Count', field: 'count', width: 100}
    ];

    this.gridOptions = {
      rowSelection: 'multiple',
      cacheBlockSize: 30,
      rowModelType: 'infinite',
      paginationAutoPageSize: true,
      suppressRowClickSelection: true
    };

Answer №1

1. To include a checkbox column in Column defs:

columnDefs: [
    {
        headerName: '',
        width: 40,
        field: 'checkbox',
        width: 50,
        checkboxSelection: true,
        showDisabledCheckboxes: true
    }
]

2. Implementing a Custom Checkall checkbox:

<script>
    $(document).ready(function () {
        //--Add CheckAll Checkbox
        let checkAllHtml = '<div ref="eWrapper" class="ag-wrapper ag-input-wrapper ag-checkbox-input-wrapper divCheckAll" id="divCheckAll" role="presentation"&g...click', '#checkAllCheckbox', function () {
            let checking = 'checking';
            let checkClass = "ag-checked";
            $('#divCheckAll').toggleClass(checkClass);

            var gridOptionApi = gridOptions.api;

            if ($(this).hasClass(checking)) {
                $(this).removeClass(checking);
                gridOptionApi.forEachNode(function (rowNode) {
                    rowNode.setSelected(false);
                });
            } else {
                $(this).addClass(checking);
                gridOptionApi.forEachNode(function (rowNode) {
                    rowNode.setSelected(true);
                });
            }
        });
    });
</script>
