>Hi there, that thread doesn't help, I want to set them in the IDE by dragging the column splitter with the mouse ( as you can with a listview ) but maybe you can't do it

I also was unable to do it in IDE, only through properties and then later some complex way, forgot already.

Are you using VS2005 or VS2008?

Sounds like a strange omission from the GridView control to not be able to simply resize the columns.
