Radgrid shows only on PanelBar mouse over

PanelBar

Todd asked on 06 Apr 2011, 04:51 PM

I've got a radgrid inside of a panel bar, but the panel bar contents do not show in page load UNTIL you mouse over the panel bar. Only then will the panel bar's contents appear.

The posting closest to this my problem is this posting, but it applies to a much older Telerik tools release (we're currently using RadControls for ASP.NET AJAX Q2 for .net 3.5 in a VS2008 web application). There were other causes suggested (.css formatting?!) , but those solutions do not work or didn't apply.

So... Are there any known issues that fall in with this description? Any leads, hints or links relating to this issue would be helpful.

I have tried several solutions, but none worked or were appropriate. Some of them include:

Programatically adding the AJAX contol update relationships on the page load - it worked great in ajaxifying contols, loading panels, etc, but did not resolve the grid/show/mouseover problem.
Setting the grids focus on page load - works - but doesn't work if multiple grids are in play, only the last grid given focus appears
Comparing this page(s) in question to OTHER pages in the app that are wired up the same way (data sources, binding, ajax settings, panel bar/item nesting, AJAX, etc).
Creating a new page entirely, copying html and code behind, but no joy...

Thanks in advance,
Todd

Hello Todd,

I tried to replicate the problem using the code you sent, but to no avail. Can you modify the attached sample so that the issue can be seen and send it back to us? Note that I have replaced your ObjectDataSources with dynamically created ones. Also, if there are any external css styles and javascript, please make sure you include those as well.
