I was counfused as to why in support documentation tag prefix is <telerik:RadToolBarButton>, where as, in my design time for any aspx page, it shows up as <rad:RadToolBar>.
I am also seeing API differences as well. Is there something I should be worried about?.
Sorry, I see the difference now. I did not know that Telerik supports two sets of controls, one which is compatiable with ajax control tool kit called ASP.NET AJAX, and the other one called ASP.NET.
