      • I am using a DataGrid, not the Datagridview, to create a Master/Detail Grid. When I run it, it displays the Master data with a expand button on each row, which is great.

Any way of just having that child row display in place of the hyperlink I realize I can go out and get a custom 3rd party

      • I have a form with AutoScroll set to true. Now, I add some control. If I place that control so that part of its client area extends past the form, scrollbars appear accordingly. However, if I set that control's Anchor right or bottom _and_ set the minimum size property, the scrollbars never appear when the form is resized & the control goes outside the form's client area.
