Question

I have asp.net application and a TabContainer from AjaxControlToolkit on a form. There are 4 tabs, each containing UpdatePanel, hidden button and some custom .ascx (each with it’s own javascript file). Buttons are triggers for panels to update the contents and they are triggered from the ‘OnClientActiveTabChanged’ event of the TabContainer.

This technique is described here and similiar here. It’s pretty simple when looking at it.

The only problem I have is that the whole scenario works when used as a separate page but it doesn’t seem to work when masterpage is around that page. Suddenly buttons act as full postback controls.
Do you have any idea what’s the reason?

Answer 1

Assuming the buttons your referring to are on the master page, I think you’ll want to register the master page buttons as update panel triggers.
