I have a number of tabs with with a DataGridView on each. When I change the row color on some of the GridViews the change doesn't take place until I click the last tab. Then going back to the other tabs, first then, I can see that the row colour has changed.
What do I need to update in order for the change to take place, without the need to click the last tab?
