If you activate another form while a form containing a Grid control is showing, the Grid repaints itself.


When the grid loses focus, it automatically repaints the entire grid. The grid should only paint the section of the grid that was covered or changed -- not the entire grid -- when it loses focus.


There is no known workaround at this time.


Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This problem has been corrected in Visual Basic version 4.0.


Steps to Reproduce Problem

  1. Start Visual Basic or from the File menu, choose New Project (ALT, F, N) if Visual Basic is already running. Form1 is created by default.
  2. From the File menu, choose Add File (ALT, F, A) and add GRID.VBX to the project and add a grid (Grid1) control to Form1.
  3. From the File menu, choose New Form (ALT F, F). Form2 is created.
  4. Add the following code to the Form_Load event procedure of Form1:

       Sub Form_Load ()
          Grid1.Rows = 20
          Grid1.Cols = 8
          'Initialize the grid with random data
          For I = 0 To 19
             Grid1.Row = I
             For J = 0 To 7
                Grid1.Col = J
                Grid1.Text = Format$(I) + Format$(J)
             Next J
          Next I
       End Sub
  5. From the Run menu, choose start (ALT, R, S) or press F5.
  6. Position Form2 to cover a portion of the grid, click back and forth between the two forms, and notice that the grid is repainted each time Form2 is activated.
