Hope someone can point me in the right direction in accomplishing this. Trying to group rows of a data bound DataGridView in winform c# application, and have the row header span across the group. I have the DataGridView grouping and displaying the results, but not having any luck getting the row header to span. Tried this link How to Merge DataGridView Cell in Winforms but couldn’t get it adapt to what I need.

DataGridViews. If that's not good enough you are out of luck. - TaW
