can't drag or add Rad control -- get "Error creating control" error

[HL]

hi all:
  I tried to add RadCalendar and RadCombox to my application . I got the error "Error creating control". I tried to unistall telerik control then re install. I still got the same error. I added the Telerik.web.ui control under the Global assemble but I still get the same error

Did I miss any thing on my PC when I download Telerik control? Please see attached screen shot


Thanks
Helena

Hello Helena,

I attached a sample project that has a Calendar and ComboBox on the page and everything seems to be OK. I am sure you have the Telerik.Web.Design.dll in the BIN folder, so I can't say what might be causing the problem. Even though these errors appear at design time, they do not affect the run-time behavior of the controls and you should not have any problems when running the application.

Greetings,

I fixed it by Shinu help(Please see http://www.telerik.com/community/forums/aspnet-ajax/combobox/can-t-add-radcombox-control-to-the-page.aspx)

Basically what I did is to add Telerik control at the GAC then deleted the Teleril control from project bin folder. Before I didn't delete the telerik control from bin folder, so It gave me error even I added to GAC


Thanks
