I forgot to include this code at the bottom of view file:
@(Html.Telerik().StyleSheetRegistrar()
.DefaultGroup(group => group
.Add("telerik.common.min.css")
.Add("telerik.vista.min.css")
.Add("telerik.rtl.min.css")
))
@(Html.Telerik().ScriptRegistrar()
.jQuery(false)
.jQueryValidation(false)
)
Now I see Telerik graphics correct.
Best Regards
