Delete confirmation of datagrid inside RadAjaxLoadingPanel is not working

[mohsin]

Hi,

I am converting <telerik:AjaxLoadingPanel to <telerik:RadAjaxLoadingPanel in all of our DNN modules.
New  <telerik:RadAjaxLoadingPanel is fine.

But i am having a problem, i have few datgrids inside RadAjaxLoadingPanel.
Those grids are working fine except the delete confirmation button is not triggaring the DeleteCommand event,
 but it was working fine inside previous AjaxLoadingPanel.

I have used 2 methods, both were working well but now they are not working.

#1 methos
----------------------------------------------
markup
========
Here is my code inside RadAjaxLoadingPanel inside Datagrid

<asp:TemplateColumn>
<ItemTemplate>
<asp:Button id="btnAutoAddDelete" runat="server" Text="Delete" CommandName="Delete"
 OnClientClick="return confirm('Are you sure you want to delete this item?')"
UseSubmitBehavior="true"></asp:Button>
</ItemTemplate>
</asp:TemplateColumn>


#2 Method
--------------------------------------------
Here, onlclick is set by codebehind

codbehind
 ============
Private Sub DataGrid3_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles Datagrid3.ItemDataBound
            Dim btnAutoAddDelete As Button
            If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
                btnAutoAddDelete = CType(e.Item.Cells(0).FindControl("btnAutoAddDelete"), Button)
                btnAutoAddDelete.Attributes.Add("onclick", "return confirm_delete();")
            End If
 End Sub

Here is my code inside RadAjaxLoadingPanel inside Datagrid

<ItemTemplate>
<asp:Button id="btnAutoAddDelete" runat="server" Text="Delete"
CommandName="Delete" CausesValidation="false"></asp:Button>
</ItemTemplate>
</asp:TemplateColumn>


-------------------------------------------

I can not understand where is the problem!

Is there anyone to help me out?


Thanks for your time

Hi mohsin,

Please try modifying the button declaration as below and see if it works:

<asp:Button id="btnAutoAddDelete" runat="server" Text="Delete" CommandName="Delete"
 OnClientClick="if(!confirm('Are you sure you want to delete this item?')) return false;">
</asp:Button>

Additionally, you can review this help artcile on client confirmation with RadAjax.
