I have used the DataGridView.Paint event to make the top 2 rows appear as if their cells span the necessary months and weeks as shown above.

The problem is, when I scroll (using the DataGridView scrollbars), the content of the top 2 rows smear and the text flows together.

How can I avoid the smear when scrolling?

HiGorlist,

You can handle the Scroll event of the DataGridView and force the cell to repaint by calling the InvalidateCell method. Here is a sample for your reference.

Let me know if this helps. If not, could you please provide more detailed information? Some code would be helpful.

Best regards.

Hi Rong-Chun,

That is exactly what I needed!

This solved my problem:

Private Sub dgwEdit_Scroll(ByVal sender As System.Object, ByVal e As System.Windows.Forms.ScrollEventArgs) Handles dgwEdit.Scroll

dgwEdit.InvalidateRow(0)

dgwEdit.InvalidateRow(1)

End Sub
