radcombobox on master page is not working with one content page, but working on other pages AJAX issue??

[Ruby]

I have a master page with multiple content pages. The master page contains a radcombobox with checkbox, as soon as the checkbox is checked page reloads and based on the dropdown data and activities shows up on the content pages.
The above procedure works on all the content pages, except one. Here as soon as the checkbox is checked or unchecked. It remains checked always and nothing happens on the page.

It looks like an AJAX issue but not sure.
Could someone please help me with this.
Thanks,

Hello Ruby,

There has to be something specific in the implementation of the content page that does not reload.
You can compare this page code with the code of another page that reloads.
Additionally you can check if there are any JavaScript errors on the page.

All the best,

Thanks Kalina, this issue has been resolved.
The page was not working because Required Field validator was preventing Auto post back on this page.
I have set the CausesValidation property of Radcombobox to false and everything started working.
Followed code from this forum: http://www.telerik.com/community/forums/aspnet/grid/required-field-validator-stops-auto-post-back.aspx

I have been struggling with this issue since 2 days.

Telerik team you are AWESOME!!!, thanks for your help and Support.

Thanks,
