Please fix. This is really annoying because all controls in the RadGrid will then have a Visible property value of false, even if they are visible.

Hi,
This behavior is basically expected due to RadAjaxManager internal logic of placing the controls within update containers. In order to the Visible property to return true, you can place the RadScriptBlock before the RadGrid controls. Alternatively, you can try to remove the RadAjaxManager and wrap the RadGrids with RadAjaxPanel.
I hope the clarification was helpful.

The problem with suggestion #1 is that in code-behind, if I'm handling the ItemDataBound event, the grid's visibility is false.
The problem with suggestion #2 is that the RadAjaxPanel is useful in only the most trivial use cases. I have complex Ajax scenarios that require the use of the RadAjaxManager.

Hello,
The ItemDataBound logic should be fine though. I've created a sample RadGrid web site to test the described behavior. Please run the attached web site and let me know about the result.
