Hello,

You can use the property EnableInternalRowsManagement="true" of DisplayLayout tag
And JS code for selecting row in the client side. Please take a look at the code below:

<DisplayLayout>
<ClientSideEvents CellClickHandler="Fire" />

JS code for selecting row:
<script type="text/javascript">

        function Fire(gridName, cellName) {
            //var grid = igtbl_getGridById(gridName);
            // var row = igtbl_getRowById(cellName);
            var cell = igtbl_getCellById(cellName);
            cell.Row.setSelected(true);

            debugger;
        }
    
    
    </script>

Hope this helps.
