I have been using Visual Studio 2008 for some time but have never used the Master Page functionality. When building standard web forms I can switch to Deisgn mode and drag and drop controls onto the page...no problem there.
The issue I am having now is that I created a very basic master page and a content page. The master page simply has an image header with a single content placeholder. I then created a content page that referecnes the master page and have some text displaying in the content palceholder. I can call up the content page fine and it pulls in the master page and looks great. Everything is good up till this point.
ok, now I want to add a gridview to the content page. I bring up the content page in VS and click the Design tab to go into design mode so I can drag and drop and gridview control. When I click the Design tab I see a brief message saying loading master page. I then see the page with the header on the master page but I dont see text from the content page at all and I cannot edit the page at all. The window is greyed out and I cant drag any controls onto it. its almiost like it is locked from editing. I can switch back to the source window and add controls there and see them when I load the page....but still nothing in design mode. why? Thanks
