Hello.
I use radwindow in my frame to open pages .I find it's very slow to load the pages and input data in the pages.But when i open the pages in browser , all work perfect.
I limited radwindow to 8. but the performance problem still appears.
Is there any performance impact while using Radwindow?
I want implment a UI frame like Ext does. 

How to get help from you.
Best Regards.

Hello John,

Can you please make sure that the ShowContentDuringLoad property is set to true? When this property is enabled, RadWindow acts exactly like an IFRAME and shows the content as it is loaded (if showcontentduringload is set to false, RadWindow will wait for the whole page to be loaded first).



Kind regards,

hi Georg,
I have a similar issue about the performance. For my case, I used the radwindow to "Edit" in RadGrid, as I can not set ShowContentDuringLoad to True, cause it's caching the last record you opened, it would be amibiguous when you check different records. And I have many other rad controls on the radwindow, it would take 10-15 secs to open the window, seems a little bit slow.
Just wondering is there any way to increase the performance?
thx

Hi Wenchao,

For SP2 that will appear in mid January, we have improved the logic behind the ShowContentDuringLoad property. With the new implementation, if this property is set to false, RadWindow will show a "loading" animation instead of the content until the content page is completely loaded. We believe that this change will help a lot in scenarios like the one that you have.

For the time being you can avoid the caching, and reload the page in RadWindow every time when the window is loaded by setting the ReloadOnShow property to true.



All the best,
