ASP.NET程序中常用编程代码(二)

ddlShipType.DataBind();

ddlShipType.SelectedIndex = ddlShipType.Items.IndexOf(ddlShipType.Items.FindByValue(dv.Table.Rows[0]["OrShipType"].ToString()));

3、在编辑嵌套在Datalist内的Datagrid某条记录时定位它所在的Datalist行

protected void MyList_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)

{

if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)

{

HtmlInputHidden odid = (HtmlInputHidden) e.Item.Cells[0].FindControl("odid");

DataListItem item = (DataListItem)e.Item.Parent.Parent.Parent;

DropDownList flag = (DropDownList)item.FindControl("ddlFlag");

if(flag.SelectedIndex == 0)

{

if(e.CommandName == "Delete")

{

int iOdId = Convert.ToInt32(odid.Value);

//删除订单明细方法

OrderSO.DeleteOrderDetail(iOdId);

}

}
