Exceptions
ExceptionDescription
System.ArgumentOutOfRangeException

The rowIndex is less than 0 or greater than RowCount minus 1.

-or-

The cellIndex is less than 0 or greater than the number of Cells in the Row minus 1.

System.ComponentModel.InvalidEnumArgumentException

The direction is not one of the System.Windows.Forms.Orientation values.

-or-

The mode parameter is not one of the MultiRowSelectionMode values.

System.ArgumentExceptionThe mode is not MultiRowSelectionMode.ContainedCells and MultiRowSelectionMode.IntersectedCells.
Example
The following code example shows how to use this method to retrieve all intersected HeaderCells in the ColumnHeaderSection and Row and paints the HeaderCell as needed. This example is part of a larger example for the Office2007Style class.
