Since Q3 2011,
all existing skins, except Default
, are moved to a separate skins assembly (Telerik.Web.UI.Skins.dll
By doing so, we were able to reduce few megabytes off the main assembly and
transfer that load to the skins assembly. And though 6 megabytes might seem
modest for some, it's some 40% reduction
in terms of the file size: Separate Skin Assembly in RadControls for ASP.NET AJAX with Q3'11.
As it was mentioned four months
ago, all embedded skins (except the Default
one, which will remain
plugged in the Telerik.Web.UI.dll
) will be shifted to the
and to utilize any embedded skin other than the
skin, you will have to have a valid reference to the new AJAX
skins dll in your project.
If a different from the Default
skin is set and the Telerik.Web.UI.Skins.dll
is not present in the /Bin folder, the following server error will appear on the page:
Telerik.Web.UI.[Telerik Control] with ID='[Telerik Control ID]' was unable to find embedded skin with name '[Skin Name]'. Please, make sure that you spelled the skin name correctly, or if you want to use a custom skin, set EnableEmbeddedSkins=false.
More information is available in these help articles:
Note that you should restart Visual Studio after adding a reference to the Telerik.Web.UI.Skins.dll
If you use the Telerik WebUI VSExtensions upgrade wizard
to update your projects, upgrade the tool to version 2011.3.1125.0 or later in the Extensions Manager of Visual Studio. This will ensure that the Telerik.Web.UI.Skins.dll
assembly will be copied automatically to the /bin
folder by the upgrade wizard.
