When a new web site is created In VS2005 and the RadControls folder is copied to the root of the new website, after dropping any Radcontrol onto the form and pressing F5, the following error appears: Could not load type 'Telerik.WebControls.Dialogs.ChartImage'
Visual Studio 2005 is organized in a way, that all the files in a project folder are included automatically to the web site project. When the F5 key pressed, the IDE validates the project. As the RadControls folder contains files, related to all Telerik controls (Chart, Editor, etc) they cannot be validated, because they are lacking their codebehind files (these are the respective RadChart.Net2.dll, RadEditor.Net2.dll, etc. files).
The error message is thrown when all subdirectories of the RadControls folder are copied to the project, including the RadControls\Chart folder, but not all DLLs are included in the bin folder or GAC.
To avoid/fix this error either:
In RadControls Q2 2006 the external files are included in the assembly as web resources and this error should not appear unless you copy the RadControls folder to your project.
