[Solved] Theming Telerik Controls via SkinFile in 3.5

[Linus]

Hi!

I'm trying to theme my Telerik controls via ASP.NET theming mechanism. I'm using 2008.2.723.35. We're using ASP.NET 3.5 and I've seen this being done in 2.0.  Below is my skinfile:

<%@ Register Assembly="Telerik.Web.UI, Version=2008.2.723.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> <telerik:RadCalendar runat="server"></telerik:RadCalendar>

However, upon i compile i get the error:

Type 'Telerik.Web.UI.RadCalendar' is not defined.

What's wrong here?

I should tell you that the site works otherwise, i.e. no problem loading the assembly and using the Telerik controls in the "normal" way.

Regards
Linus

Hello Linus Karlsson,

I have followed the instructions described here and created a sample project which works fine.
Please download it and give it a try.

Let me know what is different in your case.

Hey, I tried your code out and obviously it worked. My still didn't. However, thanks to this link, i realized whats's causing the error... The skin was named 'Telerik', which means at compile time it's compiled into the namespace ASP.Telerik, hence messing up the runtimes ability to locate Telerik.Web.UI.XRadControl.

Solution, don't name your skin Telerik :)

Hi All,

This is kind of an old thread but I've got the same problem on the current version of the controls.  I'm trying to use the Telerik skin (not one I'm calling Telerik),  all others such as Web20 (my normal) work just fine but when using the Telerik skin I get the 'Telerik.Web.UI.RadCalendar' is not defined error.

Is there an alternate name that the Telerik skin goes by?

My skin file for the Telerik skin/theme is shown below.

Thanks for any assistance.

Regards,

Jon

Hello Jon,

Unfortunately themes with the name of Telerik are not supported in RadControls for ASP.NET AJAX. Just change the theme name to work around that.

Hi Kamen,

Do you mean that the skin file name needs to be changed to something like TelerikSkin while retaining the content (with Telerik) as pasted in.

This problem is occuring because the Telerik theme that ships with the controls is called Telerik - not through any custom skin of mine...

Jon

Hello Jon,

ASP.NET themes called "Telerik" are not supported, because the ASP.NET framework messes up the RadControls namespace with the theme's namespace.

So you have to rename your ASP.NET theme. The "Telerik" skin name that RadControls use is something different.

We don't ship any ASP.NET themes named "Telerik". There are two ASP.NET themes called "Default" and "Vista" in the Demos website.

Kind regards,
