Remarks

This class is a base class for other header cell classes, such as ColumnHeaderCell, CornerHeaderCell, and RowHeaderCell. To create custom row header icons or column header glyphs, inherit from the HeaderCell class and add functionality to paint your own icon or glyph.

Note to Inheritors:

When you derive from HeaderCell and add new properties to the derived class, be sure to override the Clone method to copy the new properties during cloning operations. You should also call the base class's Clone method so that the properties of the base class are copied to the new cell.

Example

The following code example shows the HeaderCell's important properties. The GutterStyles draw gutters around the HeaderCell and they represent the cell's orientation. The hover effect is drawn by the HoverDirection property. By default, the HeaderCell uses the VistualStyle backcolor to draw the background. You can set the FlatStyle and UseVisualStyleBackColor and then change the HeaderCell's Cell.Style. The SelectionMode property indicates which cell or rows are selected when you click the HeaderCell.
