[Solved] CSS style not applied after postback

[Andy]

Hello!

I'm experiencing weird issue with RadUpload control. When the page initially loads, everythings looks fine, but after I click "Load" button, the postback occures and "Browse..." button of the RadUploader seems to lose it's css style.
I'm stuck with this one, so I really hope you guys can help me out. Thanx a lot in advance!

Here's the content of my aspx page:

<

 

asp:Content ID="Content1" ContentPlaceHolderID="plcContent" runat="server">

 

<

 

style type="text/css">

 

 

.RadUpload_artUpload .ruBrowse

 

{

 

background-color: #dcf0ff;

 

 

border: solid 2px #aadcff;

 

 

height: 23px;

 

 

width: 86px;

 

}

 

</

 

style>

 

 

 

 

<asp:Button ID="btnLoad" runat="server" Text="Load"/>

 

 

<telerik:RadUpload ID="ruFileUpload" MaxFileInputsCount="1" Skin="artUpload" ControlObjectsVisibility="None" runat="server" Localization-Select="Browse..." EnableEmbeddedSkins="false" />

 

</

 

asp:Content>

Hello Andy,

First off, please check if your are really using RadUpload for ASP.NET "Classic" or RadUpload for ASP.NET AJAX. We think it's the latter.

Anyway, we tried to repro the reported issue using the provided code snippet, but to no avail. Please try to provide additional detail on your implementation.

Best wishes,

Oh, I'm terribly sorry, my bad. Yes it's Ajax. Could you move the thread to the right place please?

As for the issue - today I've noticed that the issue occures only in Internet Explorer 7 (don't know about 8). In Mozilla it works fine.
Have you tried to repro it in IE?

Thanx a lot!
Andy.

Yes, Andy, we've tested your code snippet under IE, FF, Chrome and Safari.

Maybe you've hit the notorious limitation of Internet Explorer - it can load up to 32 CSS files and if there are more, they will be ingnored. This problem can occur in case you are using a theme with a lot of CSS (when you register the theme, automatically all the CSS is declared) or you have declared a lot of RadControls on the page. If you are using a theme you can test my assumption by removing it and test whether the RadTabStrip CSS will load correctly.

If this is the case I suggest to either use a RadStyleSheetManager which will combine all the CSS on the page or reduce the CSS files used.

Kind regards,
Paul
