UltraGrid中按钮背景颜色无法显示

在设置UltraGrid表格中按钮背景颜色时，无法成功显示
this.ultraGrid1.UseOsThemes = DefaultableBoolean.False;
把UseOsThemes 设置为False
在事件中或者初始化赋值，都可以成功显示按钮背景色
private void ultraGrid1_InitializeRow(object sender, Infragistics.Win.UltraWinGrid.InitializeRowEventArgs e)
{
e.Row.Cells[0].ButtonAppearance.BackColor = Color.Green;
e.Row.Cells[0].ButtonAppearance.ForeColor = Color.White;
}
this.ultraGrid1.DisplayLayout.Bands[0].Columns[“Station”].CellButtonAppearance.BackColor = Color.LightBlue;
