Exceptions
ExceptionDescription
System.ArgumentOutOfRangeExceptionThe rowIndex is less than 0 or greater than RowCount minus 1.
System.ComponentModel.InvalidEnumArgumentException

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

-or-

The mode is not one of the MultiRowSelectionMode values.

System.ArgumentException

The mode is not MultiRowSelectionMode.ContainedCells and MultiRowSelectionMode.IntersectedCells.

-or-

The cellName does not match the name of any Cell in the Row.

Example
The following code example shows how to use this method to retrieve all intersected HeaderCells in the ColumnHeaderSection and Row. This example is part of a larger example available for the Office2007Style class.
