RadGrid Style Error

[AP]

I've tried creating a new style in the Visual Style Builder, selecting just Grid from the control list. I;ve then downloaded the zip, and copied the files into my project.

On one page, I've disabled the embedded styles of the RadGRid, and set the style to the name of the custom style.  I have also created links to the stylesheets:-

<link href="App_Themes/Grid.TestStyle.css" rel="stylesheet" type="text/css" />
   <link href="App_Themes/Menu.TestStyle.css" rel="stylesheet" type="text/css" />
   <link href="App_Themes/Input.TestStyle.css" rel="stylesheet" type="text/css" />
   <link href="App_Themes/Slider.TestStyle.css" rel="stylesheet" type="text/css" />
   <link href="App_Themes/Calendar.TestStyle.css" rel="stylesheet" type="text/css" />

In design mode the grid looks OK, showing the correct colours etc, but on running the page, I get the error:-

Telerik.Web.UI.GridFilterMenu with ID='rfltMenu' was unable to find embedded skin with name 'TestStyle'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false.

The Radgrid definition is:-

Any ideas why this is happening.

Hello Andrew,

The error can be observed if you override the EnableEmbeddedSkins property of the filtering menu, which is a RadMenu. In standard scenarios the filtering menu will inherit the Skin and EnableEmbeddedSkins properties from the RadGrid. Please check in the code-behind or in the ASP.NET theme.

By the way, CSS files, which are located inside the currently used ASP.NET theme, are registered automatically by the ASP.NET framework and you don't need to register them manually - actually in this case you will have them twice on the page.

If the problem persists, we will need a runnable demo to take a look.

Regards,
Dimo

Thanks for this.
 
I unchecked the Enable Filtering on the General Features section of the Rad GRid tasks pop-up, and it all seems to work.

The themes folder is a throwback to when the application had themes enabled (it's quite a long standing app that gets an upgrade every year), so they're not being included twice.
