WinForms Data Grid - How to display a custom button within a column header

This example demonstrates how to "create" and display a custom button within a column header.

The CustomDrawColumnHeader event is handled to draw a clickable region within the column header.

void OnCustomDrawColumnHeader(object sender, ColumnHeaderCustomDrawEventArgs e) {
    if(e.Column == null) return;
    DefaultDrawColumnHeader(e);
    DrawCustomButton(e);
    e.Handled = true;
}
