I am trying to upload a dll for a control that I wrote that extends the search result control. I need the search results to direct to a news article with ta custom URL. I am attempting to upload the control using the mechanism provided when you are editing a page. When I try and upload the dll, I get the following error:
"Unable to cast object of type 'Telerik.Search.WebControls.SearchResultToolboxItem' to type 'System.Drawing.Design.ToolboxItem'."
The dll still ends up in the bin directory, but there is no toolbox item to use from within the edit page interface. I have also attempted to directly copy the dll into the bin directory but don't know what th;e web.config entry should look like in the toolbox area. Am I missing something in the dll? Can you give me an example of what the web.config entry should look like for uploading the control manually?
Any help on this issue would be greatly appreciated.
