I have the following is my grid template column and the code behind grid databound and item command.

How can i add radconfim to the same? When user chooses yes, i want the code in item command to execute. 

<telerik:GridTemplateColumn UniqueName="Retrieve"> 

<ItemTemplate><asp:LinkButton ID="lnkRetrieve" runat="server" CausesValidation="false" CommandArgument='<%# cstr(Eval("id"))%>'  CommandName="Retrieve" Text="Retrieve"></asp:LinkButton>
</ItemTemplate>
</telerik:GridTemplateColumn>

Private Sub grd_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles grd.ItemDataBound If TypeOf e.Item Is GridDataItem Then
Dim llnkRetrieve As New LinkButton
  llnkRetrieve =
CType(e.Item.FindControl("lnkRetrieve"), LinkButton)
llnkRetrieve.Attributes.Add(
"onclick", "return confirm('Are you sure you want to retrieve?');")
End If 

End Sub

 

Protected 

 

Sub grd_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles grd.ItemCommand
If e.CommandName = "Retrieve" Then
dim CommandArgument As String() = e.CommandArgument.ToString().Split(",")
  Session(
"ID") = CInt(CommandArgument(0))

 Respose.Redirect(

"Page.aspx", True) End If
End Sub

Hello usr9999,

In order to get the desired result you should go through the following steps:

1) Cancel the postback of the button (this is needed because the radconfirm does not block the thread) as shown below:

llnkRetrieve.Attributes.Add("onclick", "confirm('Are you sure you want to retrieve?',  confirmCallBackFn);return false")

2) Use a client javascript callback function as shown above

3) Check the argument of in the callback and do the corresponding operation (e.g if you need to make a server call use the built-in javascript __doPostBack function as explained here: http://geekswithblogs.net/mnf/archive/2005/11/04/59081.aspx)

Detailed help article about radconfirm and how to use it is available below:

http://www.telerik.com/help/aspnet-ajax/window_dialogsconfirm.html

A sample demo is uploaded here:

I hope that my explanations and the provided resources are helpful, let me know how it goes.

Best wishes,
