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">  
            <MasterTableView  AutoGenerateColumns="False" DataKeyNames="ImageID">  
                <Columns> 
                    <telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName"DeleteColumn" ConfirmText="Are you sure ?"/>  
                    <telerik:GridBoundColumn DataField="ImageID" HeaderText="Image ID" SortExpression="ImageID" 
                        UniqueName="ImageID"  Visible="false">  
                    </telerik:GridBoundColumn> 
                    <telerik:GridBoundColumn DataField="ArtistID" HeaderText="Artist ID" SortExpression="ArtistID" 
                        UniqueName="ArtistID"  Visible="false">  
                    </telerik:GridBoundColumn> 
                    <telerik:GridTemplateColumn DataField="ImageThumbURL" UniqueName="ImageThumbURLColumn" HeaderText="Artist">  
                        <ItemTemplate> 
                            <asp:Image ID="ImageThumbNail" runat="server"></asp:Image> 
                        </ItemTemplate> 
                    </telerik:GridTemplateColumn> 
                    <telerik:GridBoundColumn DataField="ImageDisplayFilename" HeaderText="Image" SortExpression="ImageDisplayFilename" 
                        UniqueName="ImageDisplayFilename" DataFormatString="<nobr>{0}</nobr>">  
                    </telerik:GridBoundColumn> 
                    <telerik:GridBoundColumn DataField="ImageThumbURL" HeaderText="ImageThumbURL" SortExpression="ImageThumbURL" 
                        UniqueName="ImageThumbURL" Visible="False">  
                    </telerik:GridBoundColumn> 
                    <telerik:GridTemplateColumn DataField="IsPrimaryImage" UniqueName="IsPrimaryImage" HeaderText="Primary Image ?">  
                        <ItemTemplate> 
                           <asp:Label ID="LabelPrimary" runat="server" Text="Label"></asp:Label> 
                        </ItemTemplate> 
                    </telerik:GridTemplateColumn> 
                      
                      
                </Columns> 
                <RowIndicatorColumn Visible="False">  
                    <HeaderStyle Width="20px" /> 
                </RowIndicatorColumn> 
                <ExpandCollapseColumn Resizable="False" Visible="False">  
                    <HeaderStyle Width="20px" /> 
                </ExpandCollapseColumn> 
                <EditFormSettings> 
                    <PopUpSettings ScrollBars="None" /> 
                </EditFormSettings> 
            </MasterTableView> 
            <PagerStyle Mode="NextPrevAndNumeric" /> 
 
<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 ?
