Description

GetFirstVisibleRow is an Integer function used to get the row number for the first visible non-fixed row in the grid. A visible row is one which starts after the fixed rows specified in FixedRows and has a non-zero height for the row in RowHeights.

The return value contains the row number (zero-based) for the row matching the criteria. If a non-fixed row with a non-zero height is not found, the return value is set to RowCount.

GetFirstVisibleRow is called from the KeyDown method when handling Tab key navigation for the grid control.
