Hopefully, this is a pretty simple question. Using the CextGridWnd, how can I tell if the row is visible. For example, I have 20 rows in my data set, but am currently showing the first five rows. I would like to, programmatically, tell if row 10 is visible. In this situation, it would return a false. However, the user could have used the scrollbar to scroll to row 10. So, then, the value would be true.

The CExtScrollItemWnd::OnSiwGetVisibleRange() method returns a CRect object containing the row and column indices of the visible rows and columns. This method works independently of the selected scrolling strategies.
