注：模闆列中的事件如何寫？手工寫事件，如btn.OnClick += ...;
注：視圖模闆請參考文檔《ASPxGridView.Templates》

decimal change = (decimal)grid.GetRowValues(e.VisibleIndex, "Change");
label.Text = string.Format("{0:p}", change);
// 設定模闆列image控件的圖像
System.Web.UI.WebControls.Image img = (System.Web.UI.WebControls.Image)grid.FindRowCellTemplateControl(e.VisibleIndex, null, "changeImage");
img.Visible = false;
if(change != 0) {
img.Visible = true;
img.ImageUrl = change < 0 ? "~/Images/arRed.gif" : "~/Images/arGreen.gif";
label.ForeColor = change < 0 ? Color.Red : Color.Green;
}
