The content in RadPane is all blank when I push the Search Button.

[liu qingshui]

The problem is that RadPane--rpLeft which contain a usercontrol  is all blank when I make a search.The
strange thing is that  I click the RadSplitBar to collapse this pane and then click the RadSplitBar again to expand.
All content in this Pane is there.I don't know what cause this problem. I gusee it maybe the usercontrol in this pane.
Could someone give me some idea? I will appreciate it.

Hi liu qingshui,

Your code seems to be correct and I am afraid I cannot tell you what might be causing the issue. I prepared a test demo based on it but unfortunately to no avail - everything works fine. However, what I can assume is that a js error is thrown or you have incorrectly configured AJAX.

This being said, what I can suggest is to examine my test demo, modify it in order to reproduce the problem (but keep it still fully runnable) and share the full source code along with detailed reproduction steps and explanations so that I will be able to directly run and debug the problematic code on my side. Another option is to provide a live url along with detailed explanations and  I can try to resolve the problem by examining it if this is possible based only on a live url.

Kind regards,
