    Bug in DataGridView - invisible column turns visible...???

    In my current project I've got some DataGridViews containing multiple hidden
    columns.

    For some reason 8 of the 10 grids I've got on my form has suddenly started
    showing 1 of the hidden columns (not all of them). If I look at the grids in
    the designer, the columns ARE invisible, but still they're shown at runtime.

    I cannot figure out why. I've searched the entire project to see if I could
    find any code setting the columns visible, but there isn't any.

    Has anybody got a suggestion?

    Cheers,
    Johnny J.

      Can you post a simple but functional code sample to illustrate your issue?

          Not really, I tried posting screenshots though, but OE wouldn't let me do
          that. Said the post was too large... :-(

          I've got a Tab control with five tabs. On each tab I have 2 DataGridView
          controls that are EXACTLY the same (the only difference is the displayed
          data). All data comes from the same table but are filtered out into the 10
          DataGridViews.

          On the first tab everything is ok with the two DataGridViews, but on the 4
          other tabs, the first column containing the ID is visible in both grids, and
          if I check the designer properties, visible IS set to False for the columns.

          I've tried searching the entire code and the visible property isn't changed
          ANYWHERE (which I should also know seeing that I'm the only one developing
          this application).

          Strangely enough, sometimes it helps closing down Visual Studio and opening
          it again. so it seems to be a VS problem more than a code problem.

          As I said: I don't understand it...

          Cheers,
          Johhny J.
