Recently we have upgraded the Telerik_UI_for_ASP.NET_AJAX_2020_3_1021_Dev_hotfix which we use only Telerik.Web.UI & Telerik.Web.UI.Skins

We use default skin which is Office2010Blue which is stopped working after upgrade the dll's

we have added skin in webconfig before which is working fine before for the telerik version(2013.1.417.40) <add key="Telerik.Skin" value="Office2010Blue"/> and we don't add this EnableEmbeddedSkins=false

When we try to add EnableEmbeddedSkins=false in webconfig i cant able to see the office2010blue design part in our UI which css related skins are not loading 

Error:-

Telerik.Web.UI.RadTabStrip with ID='RadTabStrip1' was unable to find an embedded skin with the name 'Hay'. 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

Thanks

Hi Tamilzhazhagan,

Back in 2013 we obsoleted the Hay skin from the Telerik.UI.Skins.dll in favor of the newly created modern skins for the controls.

https://www.telerik.com/blogs/6-telerik-asp.net-ajax-skins-going-obsolete

The thrown "Telerik.Web.UI.RadTabStrip with ID='RadTabStrip1' was unable to find an embedded skin with the name 'Hay" error indicates that the obsoleted skin is used somewhere in the application, while it cannot be found in the referenced DLL itself. In order to resolve this error, you will need either to create a custom skin with this name, or to make a global search through the whole application and remove/change all Skin="Hay" settings.

Please, accept our apologies for the caused inconveniences.

Regards,
Vessy
