Hello all,
I have this page:
With this Code behind:
Problem is, when I click on the edit button, and then I click on update, nothing happens. The update event is not fired at all or in other words, I don't get the RadAlert.
Please help...
I have this page:

Hello Chris,
I tried your code but on my side the event fired as expected with the latest official version of RadControls. You can see a video here:
http://screencast.com/t/HDHquBjKAB6
I am also attaching my test project. Check it out and let me know if you notice anything wrong with it.

Here is the thing:
In the test project you sent, you conveniently removed this from the .aspx file:
So yeah, without that, it does work. I Kindly ask you to try the code exactly as I sent it, and you'll see that it does not work. Does the telerik component conflicts with the ajaxToolkit?
Thanks,

Hello Chris,
I did not add the popup extender, as the popup control that it pointed to was not declared anywhere on your page. When I used your code without any changes, it errored out on the client, as the popup extender could not find its popup element. This prevented the AJAX request that updates the RadTreeList from firing, as the client script was already broken.
When I added an asp:Panel with the respective ID : PanelSamples, there were no client errors and the treelist also worked as expected.
The modified project is attached to this post.

Tsvetina,
Thank you very much for your help and patience. I apologize because I have been trying to recreate the problem with as little code as possible, so I did not send my code complete. Let me give it another try: I'm certain now that the problem then must be on the Panel part of the .aspx file (thank you for helping me figuring that out). Here is now the full code:
First, default.aspx:
And this is the code behind (Default2.aspx.cs):

Hello Chris,
I ran your latest code and found out the problem. It is that the RequiredFieldValidators in the Panel shown by the ModalPopUpExtender prevent the Update button from submitting the page. You could fix this by setting a different ValidationGroup for the RadTreeList:
Also, keep in mind that the same problem will expose if you have other controls trying to submit the page, therefore, you may consider declaring a ValidationGroup for these validators, so that they validate only the related textboxes.
