asp.net  web forms project.  Now I broke the IDE.  I had a working project, but somehow after adding a datagridview and sql server, the project is broken, the toolbox items only have pointer, chart and entity data source.

there are none of the standard items like buttons, panel, grid etc.  
one thing i had done was open this in the Microsoft Matrix 3;  but in there i cannot see any design view.  closed/opened the project.  im already on webapplication5 after migrating it several times to new projects...  is there a project type or ? making it not accept common controls?

Go to the complete details ...
