While deleting, I used the 'adding a delete prompt' example.
protected void OnItemDataBoundHandler(object sender, GridItemEventArgs e)
{
if (e.Item is GridDataItem)
{
GridDataItem dataItem = e.Item as GridDataItem;
string CreateDate = dataItem["CreationDate"].Text;
LinkButton button = dataItem["DeleteColumn"].Controls[0] as LinkButton;
button.Attributes[
"onclick"] = "return confirm('Are you sure you want to delete Item created on " +
CreateDate +
"?')";
}
...this works well...although I'm unsure of the way to receive the response from the "onclick" event..
thanks,

I guess you are following the steps suggested in this documentation topic (section 'Display confirmation dialog with text including column cell value'). If so, the confirm method executed in this way should automatically cancel the delete if the user choose 'No' and process the deletion in case 'Yes' is selected.

I used the radwindow for confirmation and copied the code. It works well although i'm not understanding the way to the user's response back to my code-behind to execute the deletion function.
this is the javascript
<asp:ScriptManager ID="ScriptManager1" runat="server"/>
<script type="text/javascript">
function confirmCallBackFn(arg) {
radalert("Confirm returned the following result: " + arg);
}
</script>
this is the code behind that executes the javascript
if (e.Item is GridDataItem)
{
GridDataItem dataItem = e.Item as GridDataItem;
string CreateDate = dataItem["CreationDate"].Text;
LinkButton button = dataItem["DeleteColumn"].Controls[0] as LinkButton;
button.Attributes["onclick"] = "radconfirm('Are you sure?', confirmCallBackFn); return false;";
//if yes how to call deleterow(); //routine to delete row
}

I'm assuming that the button
<asp:Button ID="Button1" runat="server" Text="Delete" CommandName="Delete"
OnClientClick="return radconfirm('Are you sure you want to delete this record?', event);" />will fire the radgrid on delete event....I've tried this and the delete event is failing to fire...this is my code
<telerik:RadGrid ID="RadGrid1" GridLines="None" AutoGenerateColumns="False"
runat="server" AllowPaging="True" AllowSorting="True"
OnItemDataBound="OnItemDataBoundHandler"
AllowAutomaticUpdates="True" AllowAutomaticInserts="True"
ShowStatusBar="True" AllowFilteringByColumn="True"
CellSpacing="0" EnableAJAX="True" onneeddatasource="RadGrid1_NeedDataSource"
oninsertcommand="RadGrid1_InsertCommand"
onupdatecommand="RadGrid1_UpdateCommand"
ondeletecommand="RadGrid1_DeleteCommand">
<
telerik:GridTemplateColumn>
<ItemTemplate>
<asp:Button ID="Button1" runat="server" Text="Delete" CommandName="Delete"
OnClientClick="return radconfirm('Are you sure you want to delete this record?', event);" />
</ItemTemplate>
</telerik:GridTemplateColumn>
protected void RadGrid1_DeleteCommand(object sender, GridCommandEventArgs e)
{
string test = ""; 　
}
