在C#中有时存在着两个嵌套循环的存在,此时可以使用两个Repeater进行循环获取到。
例如:
aspx页面中:
很明显的是,此时在页面布局中是存在着两个Repeater存在的。
aspx.cs页面中:
#region 初始化页面
public void initData()
{
string userPhone = "";
try
{
//string phone = Session["userPhone"].ToString();
//if (phone!=null && phone.Length==0)
//{
// Helper.Result(this,"!!!!!");
// return;
//}
//else
//{
//userPhone = phone;
//根据用户手机号获取用户待付订单(这里的手机号是写死的 ,注意要改)
//Index页面中最上面滚动图片从数据库中获取
DataSet daifukuanSet = FuWuOtoWeiHelper.GetSysIndexBigTupians();
if (daifukuanSet.Tables[0].Rows.Count > 0)
{
this.IndexBigTupianRepeater.DataSource = daifukuanSet;
this.IndexBigTupianRepeater.DataBind();
}
//获取服务中的大图片
DataSet IndexServiceSet = FuWuOtoWeiHelper.GetSysIndexServicesTupians();
if (IndexServiceSet.Tables[0].Rows.Count > 0)
{
this.IndexServiceImgs.DataSource = IndexServiceSet;
this.IndexServiceImgs.DataBind();
}
//}
}
catch (Exception e)
{
throw e;
}
}
#endregion
//该方法是服务图片
protected void RptAllOnItemDataBound22(object sender, RepeaterItemEventArgs e)
{
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem))
{
//string classname = ((Button)e.Item.FindControl("gDel")).Text;
DataRowView drv = (DataRowView)e.Item.DataItem;
Repeater rptProductList = (Repeater)e.Item.FindControl("IndexGoodsImgs");
//获取具体商品中的图片
DataSet IndexGoodsSet = FuWuOtoWeiHelper.GetSysIndexGoodsTupians();
if (IndexGoodsSet.Tables[0].Rows.Count > 0)
{
rptProductList.DataSource = IndexGoodsSet;
rptProductList.DataBind();
}
}
}
//该方法是商品展示信息
protected void RptAllOnItemDataBound11(object sender, RepeaterItemEventArgs e)
{
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem))
{
//string classname = ((Button)e.Item.FindControl("gDel")).Text;
DataRowView drv = (DataRowView)e.Item.DataItem;
Image image = (Image)e.Item.FindControl("goodsImg");
image.ImageUrl = drv["cContentImg"].ToString();
Label label = (Label)e.Item.FindControl("goodsName");
label.Text = drv["cContentName"].ToString();
}
}
