devexpress GridView按条件给行号上色

 private void gridView1_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e) {
             if (gridView1.GetDataRow(e.RowHandle) == null)
                 return;
             if (gridView1.GetDataRow(e.RowHandle)["COLOR"].ToString() == "true") {
                 //该行数据的该列的值为true时,背景色为红色
                 e.Appearance.BackColor = Color.Red;
             }
             else {
                 e.Appearance.BackColor = Color.White;
             }
             if (e.RowHandle == gridView1.FocusedRowHandle) {
                 e.Appearance.ForeColor = Color.White;
                 e.Appearance.BackColor = Color.RoyalBlue;
             }
         }

先找到GridView 中的事件 CustomDrawCell 双击写入代码
