columnIndexException
Int32 Int32 Int32 Int32

The column index to exclude.

rowIndexException
Int32 Int32 Int32 Int32

The row index to exclude.

selectExceptionElement
Boolean Boolean Boolean Boolean

true to select the excluded cell, row, or column; false to retain its original state.

Exceptions

columnIndexException is greater than the highest column index.

-or-

columnIndexException is less than -1 when SelectionMode is FullRowSelect; otherwise, columnIndexException is less than 0.

-or-

rowIndexException is greater than the highest row index.

-or-

rowIndexException is less than -1 when SelectionMode is FullColumnSelect; otherwise, rowIndexException is less than 0.

Remarks

A rowIndexException value of -1 represents a column header, and a columnIndexException value of -1 represents a row header.

This method is useful to clear the current selection without canceling the selection of the cell, row, or column indicated by the exception indexes.

If the SelectionMode property value allows individual cell selection, this method sets the Selected property of each cell to false, excluding the cell in the row and column specified. If the SelectionMode property value allows full row or column selection, this method also sets the Selected property of each row or column to false, excluding the row or column containing the specified cell.

The excluded cell, row, or column may or may not be in the selected state when this method is called. This method selects it if the selectExceptionElement parameter value is true. Depending on the selection mode, the entire row or column may also be selected as a result.

}
Private Sub clearSelectionButton_Click(ByVal sender As Object, _
    ByVal e As EventArgs) Handles clearSelectionButton.Click
