Error with Tab Container and Tab Panel

Place the Scriptmanager on the page you have your TabControl and not the master Page.
If you want to nest ScriptManagers you will need to use a ScriptManagerProxy.

Hope this helps

Every tutorial and help I have found on the topic says it's fine for the ScriptManager to be in the Master page. Not to mention I said above I created a blank project without a master page and received the same error.

None the less, I removed the ScriptManager and WebPartManager from the master page and added them solely to my current page. Again, I receive the same error as above.

Chris,

Thanks for the reply, but I'm also having the same issue. I have new controls, a ScriptManager, and a TabPanel. I'm getting the "Error Rendering Control" message saying I need a ScriptManager.

Any word on someone finding a solution to this?

Thanks in advance,

Todd
