How to achieve this in client side

Hi Shane,

Try setting the ClientDataKeyNames to the primary DataField. When you add the value of the DateField to the ClientDataKeyNames array, RadGrid makes that column's value available through the getDataKeyValue() function of the GridDataItem client-side object.

.aspx

  . . .
<telerik:GridBoundColumn DataField="CustomerID" Visible="False" HeaderText="CustomerID" SortExpression="CustomerID" UniqueName="CustomerID">
</telerik:GridBoundColumn>
  . . .

.javascript

<script type="text/javascript">

function RowSelected(sender, args) //Client side Rowselected event of radgrid

{

alert(args.getDataKeyValue("CompanyName"));

}

</script>
