dev gridControl 自定义绘制列头颜色

1、添加事件CustomDrawColumnHeader

private void gvw1_CustomDrawColumnHeader(object sender, DevExpress.XtraGrid.Views.Grid.ColumnHeaderCustomDrawEventArgs e)

{

　　if (e.Column == null || (e.Column.AppearanceHeader.BackColor == Color.Empty && !e.Column.AppearanceHeader.Options.UseBackColor))

　　　　return;

　　Rectangle rect = e.Bounds;

　　rect.Inflate(-1, -1);

　　 // 填充标题颜色.

　　e.Graphics.FillRectangle(new SolidBrush(e.Column.AppearanceHeader.BackColor), rect);

　　e.Appearance.DrawString(e.Cache, e.Info.Caption, e.Info.CaptionRect);

　　 // 绘制过滤和排序按钮.

　　foreach (DrawElementInfo info in e.Info.InnerElements)

　　{

　　　　if (!info.Visible) continue;

　　　　ObjectPainter.DrawObject(e.Cache, info.ElementPainter, info.ElementInfo);

　　}

　　e.Handled = true;

}

2、设置列头颜色

gvw1.Columns["Zxnum"].AppearanceHeader.BackColor = Color.Yellow;

gvw1.Columns["Zxnum"].AppearanceHeader.ForeColor = Color.Black;
