Hi!

I have a RadContextMenu with several RadMenuItems in an Ajax UpdatePanel.
For some of the menu items I need to perform a full Postback (but not for all).

The most obvious way for me to do that is to use RegisterPostBackControl on the RadMenuItem:
ScriptManager.GetCurrent(Page).RegisterPostBackControl(this.RadContextMenu1.Items[0]);

This doesn't seem to work on a RadMenuItem.
The postback is performed but the expected behaviour (exporting a radgrid to Word) is not done. Instead the text "509|updatePanel|RadContextMenu1Panel|MenuItem1MenuItem2|" is rendered.

If I register the contextmenu instead it works but then all menu items will perform a postback:
ScriptManager.GetCurrent(Page).RegisterPostBackControl(this.RadContextMenu1);

Any suggestions on how to solve this?

Thanks
/Mats

Hi Mats,

To overcome the problem you can try the following approach:

Add a button in a hidden <div> placed outside of the updatePanel on the page:

    
            <div style="display: none;"> 
        
              <asp:Button ID="exportButton" runat="server" Text="PostBack" OnClick="exportButton_Click"></asp:Button> 
        
            </div>

Define the OnClientItemClicking event handler:

    
            <script type="text/javascript"> 
        
            function onClientItemClicking(sender, eventArgs) 
        
            { 
        
                if (eventArgs.get_item().get_text() == "Export") 
        
                { 
        
                    $get("exportButton").click(); //full postback

                } 
        
            } 
        
            </script>

In the code behind do the necessary action in the exportButton_Click event handler.

I hope this helps.
