GridButtonColumn buttons not working after .NET 4.0 upgrade

[Solomon]

I have a RadGrid (along with a RadAjaxManager and RadAjaxLoadingPanel). The version is 2010.1.309.

The grid contains two GridButtonColumns (for edit and delete).  Everything was working fine until I upgraded the website from .NET 3.5 to 4.0. Now when I click on a button, the loading panel shows up for a second, but nothing happens. I can see the code is running on my button event handlers (edit command does a Response.Redirect and the delete command deletes the object). In fact, the object is actually deleted, but I need to refresh the page to see it. If I remove the RadAjaxLoadingPanel, it seems to work ok (but I get another error when trying to page). Any thoughts on this? I don't have access to a newer version, so hopefully there a fix for this version?

Hello Solomon,

Are you by any chance using RadComression? There is an issue in .Net 4.0 which prevents our module from working as expected when the page is redirected. We've implemented a workaround in later versions, however the one you are using is suffering from this issue. If this is the case you can either use the Redirect() method of RadAjaxManager instead. Let me know if that helps or if your problem is different.

Sincerely yours,
Pavel

I was using RadCompression and disabling it worked like a charm. Thanks!
