I cannot drag web custom controls from toolbox to web form
I have created some web custom controls (both composite controls or derived/inherited controls).  I successfully added them to the toolbox. However, when I try to drag them onto the form, the cursor changes into a black circle with a diagonal line, and cannot drag them.  I also tried double-clicking them from the toolbox but it still won't work.

Has anyone encountered such a problem?  Any suggestions or solutions?   Thanks. I...
