Double click and get value from selected

[James Shelton Agar]

Hi, i tried to get ID from row double click, but it always shows a null.
here's my JS...

 function EditAct(sender, eventArgs) {
                var grid = sender;
                var MasterTable = grid.get_masterTableView();
                var row = MasterTable.get_dataItems()[eventArgs.get_itemIndexHierarchical()];
                alert(row.getDataKeyValue('Act_No'));
            }

which always return null
here is my Grid Click Event

<ClientEvents OnRowDblClick="EditAct" />

any assistance would be appreciated, thanks!

Hello James,

When configuring your RadGrid, make sure you are adding the names of the columns you want to access to its ClientDataKeyNames collection. Here is an example:

	<telerik:RadScriptManager ID="RadScriptManager1" runat="server" />
	<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
	<script type="text/javascript">
	function RadGrid1_RowDblClick(sender, args) {
	var index = args.get_itemIndexHierarchical();
	var tableView = args.get_tableView();
	var dataItems = tableView.get_dataItems();
	var dataItem = dataItems[index];
	var keyValue = dataItem.getDataKeyValue('ID');
	alert(keyValue);
	}
	</script>
	</telerik:RadScriptBlock>
	<telerik:RadGrid ID="RadGrid1" runat="server"
	OnNeedDataSource="RadGrid1_NeedDataSource">
	<MasterTableView ClientDataKeyNames="ID">
	</MasterTableView>
	<ClientSettings>
	<ClientEvents OnRowDblClick="RadGrid1_RowDblClick" />
	</ClientSettings>
	</telerik:RadGrid>

I hope this helps. If you have further questions, please don't hesitate to ask.

Sincerely,
