we are facing peformance issue with the Rad window.
We had a functionality on a page, with almost 4 text boxes and a grid with two columns , one with a checkbox column and another with a text column. The grid contains almost 1000 row. The page was loading pretty fast.
Based on our client requirement, he wanted to change the look and feel, and wanted the same functionality in model dialog in place of a page.
We put almost the same kind of look and feel inside a RadWindow with content template on a page, The Rad window takes nearly 20-25 sec to show up.
Runtime version :v4.0.30319
Please guide us regarding this.
