[Solved] Refresh Grid inside a radwindow

[Raymond]

I have a page with a grid A. On clicking a button in the command area of the grid A, a radwindow A is popped up with another grid B inside. Clicking a button in the command area of this new grid B, another radwindow B is popped up. After making changes, this radwindow B is then closed and try to refresh grid B. A few seconds later, grid B is refreshed. However, any keys on this radwindow A - refresh, save close and return this radwindow again cause an error of  Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.

I am in urgent to have this problem solved. any one can help me out is much appreciated.

Hello Raymond,

You are the first to report such problem, however I am not quite sure if it is directly related to the RadWindow control - I checked in Google for the error's message and got quite a lot of results.
I would suggest to check in the Net for the reason for this problem - hopefully you will find a solution. If you still experience problems however and you believe that the problem is in our controls, please open a support ticket and provide us with the following:

1. A small sample project where the error can be reproduced. Please make sure that the project can be run locally and reproduces the error every time.
2. Detailed reproduction instructions along with description of the desired behavior.
