How do you set this so the user can always see the header when scrolling up and down?
Did that work for you?
Ross,
I assume you are working with a hierarchical grid and the parent rows have been expanded. Try setting the HeaderPlacement property in the InitializeLayout event of the grid like so:
e.Layout.Override.HeaderPlacement = HeaderPlacement.FixedOnTop;
Let me know if that gives you what you want.
