Cannot Find Embedded Skin

RadMultiColumnComboBox supports only the Default skin.

Setting a different skin name will result in a runtime error like Telerik.Web.UI.RadMultiColumnComboBox with ID='RadMultiColumnComboBox1' was unable to find an embedded skin with the name 'WebBlue'. Please, make sure that the skin name is spelled correctly and that you have added a reference to the Telerik.Web.UI.Skins.dll assembly in your project. If you want to use a custom skin, set EnableEmbeddedSkins=false..
