Full Postback from RadMenuItem

[Mats]

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

Hi Mats,

Please review the following code library. In the last post I've prepared a sample project to show you how this can be achieved.

Hi Steve!

I guess that you are refering to your sample project called ExportFromContextRadMenu.zip.

In that sample you are using RadAjaxManager. In my application i use Ajax UpdatePanel so I guess that I can't use your solution.

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.

Best wishes,

Hi!

Your suggested solution works fine for me.

Ï am having the exact same problem, but the workaround for me seems really awkward. Can you provide some more information on why a RadMenuItem doesn't work as a trigger? Even better, is there a more elegant work-around?

Thanks!
