I am having performance issues with a RadWindow containing a large number of controls and two charts across several tabs. Initial load is very slow, navigation is acceptable but not ideal. Additionally, restoring from maximized takes way too long.
Link to sample application demonstrating the problem: removed due to Telerik End User License Agreement for UI for ASP.NET AJAX violation.
Due to an organizational requirement & legacy applications this solution must be run in IE 10.
Additional information: Latest version of Telerik.Web.UI, Visual Studio 2012, IE 10.0.9200.17357
Steps to reproduce:
1) Run the solution without debugging to maximize performace
2) Click the button to launch the RadWindow
3) Note the performance between when the page renders and when it becomes navigable.
4) Maximize the RadWindow - slow but acceptable
5) Restore the RadWindow - completely unacceptable
I do not know what I can do to make this better and am open to any and all suggestions to do so, including areas outside of the RadWindow itself (web config, master page, etc). As you can see in the code I have tried RadInputManager as recommended in the documentation and RadMultiPage.RenderSelectedPageOnly (with conditional binding in the code behind) to see if that would improve anything (it did not).
Please help!
