updating title through Ajax

[Albert Shenker]

I have a radwindow dialog (opened through RadWindowManager and .radopen()) that loads a page for users to enter information in a form. The form contains a button which raises an ajax update, storing the user's entered values and displaying a loading image. Once the info is saved, I would like to change the dialog's title.  I don't think this is possible to do today, or at least is quite difficult since it requires the ajax call to update the container. Anyhow, if it isn't possible today, it would be a nice piece of functionality to add to RadWindow in the future.

Hi Albert Shenker,

If you raise an event when the info is saved, you can change the Title property of the RadWindow from the server side (source). If the RadWindow is inside of a RadAjaxManager, it should update without causing a postback. See if you can change the Title property from the server side and make this functionality work.

Hopefully this helps,
Master Chief

I'm not sure what you mean by a RadWindow inside of RadAjaxManager. There is no RadWindow object since it is opened through RadWindowManager and .radopen.

Hi guys,

You can use JavaScript to do this:
1) get a reference to the RadWIndow from inside. This is done with the famous GetRadWindow function that can be seen here
2) use the client-side API of the control - the set_title(string) method

If you obtain the new title on the server you can store it in a hidden field, for example. The ready function can be called from the server by following this help article or by using the ResponseScripts collection of the RadAjaxManager if you are using one.
