radwindow jumps at each postback

[yao wang]

Hi, Telerik,

I have a radwindow U opened in home.aspx which has a restriction zone. everytime when I click any button in radwindow U, the page postback and the position of radwindow U has been changed, it looks like the radwindow U is jumping inside the home.aspx at each postback..

How to fix the problem? thanks a lot.

Hi Yao,

I am afraid that the provided information is not enough for us to determine what exactly the problem is and the reason for it. Please open a support ticket and send us a small sample project where the reported behavior can be reproduced - we will check it and do our best to help.


Kind regards,

I have this same problem. I have the RadWindow inside an update panel. Everytime a post back occurs, the RadWindow position resets to the original position. It does not appear ot be saving it's current position in the viewstate. So basically I move the RadWindow, a post back happens, then the Window moves back to where it started before I moved it.

Hi Levi,

Thank you for the information - now I understand better what the problem is. Indeed, currently RadWindow does not preserve its client state - we plan to provide such feature in the future but for now I cannot give you an exact time frame. If you need to preserve the state of the control, I suggest to implement a custom logic that uses RadWindow's client-side API and store the values in a convenient location (session, cookie, etc.).

Hi Uwe,

This feature is still in our ToDo list but we are currently working on fixes and features with higher priority. Once we set a time frame for this task, I will write here again.

Hi Rohan,

The RadWindow renders entirely via JavaScript, on the client, and this is one of its main features. It allows instances to be created during runtime without any additional requests to the server which can effectively boost the performance of the application. This also means that it does not have the server render markup and send it over the wire. The price for this benefit is the fact that a postback that disposes the RadWindow will effectively destroy it, so it cannot preserve its properties (size, position).

The best way to use the RadWindow is through its client-side API and to keep it out of any postbacks (if possible), including partial ones.

All that being said, you can give the PreserveClientState property of the RadWindowManager a shot. Note that it keeps the size and position of RadWnidows from its collection in a cookie, so it works not only for postbacks but for different sessions as well. Also, a cookie may be rejected by the client's browser.
