StyleSheetManager does not update head section after ajax postback

[W Klijnsmit]

Good day,

I have a question regarding the usage of the StyleSheetManager in combination with Ajax Postbacks.

In some application scenarios we'd like to add stylesheets to the StyleSheets collection of the StyleSheetManager depending on the usercontrol we are loading after a javascript postback.

For instance:
- A button in an UpdatePanel is clicked
- An AJAX Postback occurs
- New Usercontrol is added to the controls collection of the Page
- Page_Init event of the new control is fired:

protected void Page_Init(object sender, EventArgs e)

{

    RadStyleSheetManager.GetCurrent(Page).StyleSheets.Add(new StyleSheetReference("KaosCore.Style.Widgets.FeedWall.css", "KaosCore"));

 

     

 

    RadScriptManager.GetCurrent(Page).Scripts.Add(new ScriptReference("KaosCore.Javascript.Widgets.FeedWall.js"));

 

}


- The scriptmanager loads its newly added script after the AJAX postback.
- The StyleSheetManager doen't seem to load the newly added stylesheet.

It looks like the RadStyleSheetManager loads only the Stylesheets added to the collection when the page is fully loaded ( !IsPostBack ).

Is there any way we can let the stylesheetmanager update the stylesheets in the head section with the current StyleSheets collection after an ajax postback?

Thanks in advance.

Hello W Klijnsmit,

With Q3 2010 we fixed an issue where RadStyleSheetManager was unable to combine and load style sheets after AJAX.

What is your version of Telerik.Web.UI? Could you please test with the latest version?

Kind regards,

Hello,

I'm curious if this problem was solved for W. Klijnsmit. We are currently experiencing the same issue in a similar scenario. We are also using the Q3 2010 release (2010.3.1109.40 to be exact).

Any other tips would be appreciated!

Kind regards,
Reggy

Hi Reggy,

I once again tested this with the latest version of Telerik.Web.UI and can confirm that it works. I am adding an embedded style sheet reference on postback (which is an AJAXified one) to the RadStyleSheetManager in the OnInit method. Please see the attached test project as an example.

Best wishes,

Thank you for the sample project. I'm unable to get my situation working though. I've created a sample project to reproduce my situation, but I don't seem to be able to include .zip files as attachment! :(


Cheers,

Reggy

*edit: I have opened a support ticket and included the mentioned .zip file.
