   void button4_Click( Object^ /*sender*/, EventArgs^ /*e*/ )
   {
      myDataGrid->ResetHeaderForeColor();
   }

private void button3_Click(object sender, EventArgs e)
{
   ColorDialog myColorDialog = new ColorDialog();
   // Disable selecting a custom color.
   myColorDialog.AllowFullOpen = false ;
   // Enable the help button.
   myColorDialog.ShowHelp = true ;
   // Set the initial color to the current color.
   myColorDialog.Color = myDataGrid.HeaderForeColor;

   myDataGrid.HeaderForeColor = myColorDialog.Color;
}
// Reset the header foregroundcolor.
private void button4_Click(object sender, EventArgs e)
{
   myDataGrid.ResetHeaderForeColor();
}

Private Sub button3_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button3.Click
    Dim myColorDialog As New ColorDialog()
    ' Disable selecting a custom color.
    myColorDialog.AllowFullOpen = False
    ' Enable the help button.
    myColorDialog.ShowHelp = True
    ' Set the initial color to the current color.
    myColorDialog.Color = myDataGrid.HeaderForeColor
    ' Show color dialog box.
    myColorDialog.ShowDialog()
    ' Set the header foreground color.
    myDataGrid.HeaderForeColor = myColorDialog.Color
End Sub

' Reset the header foregroundcolor.
Private Sub button4_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button4.Click
    myDataGrid.ResetHeaderForeColor()
End Sub

注解

如果要为 System.Windows.Forms.DataGrid 创建设计器或创建自己的包含 的 System.Windows.Forms.DataGrid控件，则通常使用此方法。 可以使用 ShouldSerializeHeaderForeColor 方法确定属性值是否已从其默认值更改。
