girdview下DropDownList處理

girdvIEw行裡編輯時有DropDownList，DropDownList的默認選擇值處理：



protected void gdvUserList_RowDataBound(object sender, GridVIEwRowEventArgs e)
        ...{
            if(this.gdvUserList.EditIndex>=0 && this.gdvUserList.EditIndex==e.Row.DataItemIndex)
                ((DropDownList)e.Row.Cells[2].Controls[1]).SelectedValue = DataBinder.Eval(e.Row.DataItem,"GroupType").ToString();
        }
