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.

Hello liu qingshui,

I already answered your other thread and for your convenience I pasted my reply below:

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.


All the best,

Hey Svetlina:
Thank your kindly help.  And I really don't konw what cause this problem.
After  checked all the code one by one,I found that this can be solved only by set the property
 Collapsed="false".Although this solution work,I wonder why,that's the reason behind this.
 I guess there is a  relationship between this property  and the problem.
And this relationship is key to the problem. Any idea and suggestions
will be appreciated.Thanks!

Hi liu qingshui,

I am afraid I cannot detect the problem based only on this information. The only thing I can suggest is to isolate the issue and modify my demo code in order to reproduce the issue and provide it to me or at least provide a live url. Otherwise, unfortunately, we cannot assume what might be happening since we have not seen such an issue before.

Best wishes,
