 when adding rows, you need to force a repaint (for example by
 minimizing and then de-minimizing the form).

+I did an svn update but when I run my test program I still get a very
+strange results.  First of all, I have to force a repaint (for
+example, by minimizing/de-minimizing).  Note that I confirmed that the
+refresh bug I reported in a separate bug is fixed, so this seems to be
+specific to switching data sources.
+
+Also, when I force a repaint instead of correctly replacing the rows
+and columns from the old DataTable with the new, it seems to append
+the rows and columns.
+
+Finally, as before if you set the DataSource=null, it throws an
+exception saying it cant bind type.  with SWF you can set the
+DataSource to null.  I have come across several code examples where
+the DataSource is set to null for the DataGridView in order to clear
+the grid, for example:
