In my grid I have a GridButton column with a commandname =Delete
I also have ondeletecommand=RadGridName_deleteCommand

When I click the delete button, the row is deleted, but the code in the deletecommand handler never gets executed, so how is the row deleted ? Why is the deletecommand event handler never executed. Heres the grid code

    
            <telerik:RadGrid ID="RadGridImages" runat="server" GridLines="None"   
        
                            OnItemDataBound="RadGridImages_ItemDataBound" onneeddatasource="RadGridImages_NeedDataSource"   
        
                     AllowPaging="True" PageSize="5" Skin="Vista" Width="750px" AllowSorting="True"   
        
                            BorderStyle="None"   
        
                            ShowStatusBar="True" ondeletecommand="RadGridImages_DeleteCommand">

                            <RowIndicatorColumn Visible="False">

                            <ExpandCollapseColumn Resizable="False" Visible="False">  
        
                                <HeaderStyle Width="20px" /> 
        
                            </ExpandCollapseColumn> 
        
                            <EditFormSettings> 
        
                                <PopUpSettings ScrollBars="None" /> 
        
                            </EditFormSettings>

            <FilterMenu Skin="Vista" EnableTheming="True">  
        
            <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation> 
        
            </FilterMenu> 
        
                    </telerik:RadGrid>

and heres the event handler in the codebehind. Ive set a breakpoint on the firstline, but its never reached

    
            protected void RadGridImages_DeleteCommand(object source, GridCommandEventArgs e)  
        
                    {  
        
                        GridDataItem item = (GridDataItem)e.Item;  
        
                        //Get the primary key value using the DataKeyValue.       
        
                        Int32 id = -1;  
        
                        string res = string.Empty;  
        
                        bool ok = Int32.TryParse(item.OwnerTableView.DataKeyValues[item.ItemIndex]["ImageID"].ToString(), out id);  
        
                        if (ok)  
        
                        {  
        
                            res = imagemanager.DeleteImage(id);  
        
                            if (!string.IsNullOrEmpty(res))  
        
                            {  
        
                                RadGridImages.Controls.Add(new LiteralControl("Unable to delete image. Reason: " + res));  
        
                                e.Canceled = true;  
        
                            }  
        
                        }  
        
                    }

Can anyone see whats going on here ?
