ASP.NET中 Repeater嵌套应用

      Repeater嵌套问题，可以简单的理解为双重for循环。原理其实是一样的，下面是我在项目中摸索的，编译通过，效果明显。呵呵， 好了

源码如下：

 

---

<div style="width: 924px; height: 278px; line-height:20px;"> <asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound"> <ItemTemplate> <div class="wenzi" style="background: #F9F7F7; width: 924px; height: 293px; border: 1px dashed #CCCCCC; margin: auto; margin-top: 8px; border-top: #FC89A1 solid 1px;"> <div style="width: 350px; height: 275px; float: left; margin:20px auto auto 10px;"> <a style="margin: 20px auto auto 10px; " mce_style="margin: 20px auto auto 10px; "> <asp:Image ID="Image1" runat="server" ImageUrl='<%#Eval("ImageUrlPlotos") %>' Width="301" Height="181" valign="top" /> </a> <div class="we8"> <b> <%#Eval("wineHeaderName")%></b>     <a href="../wineparty.aspx?wineHeaderID=<%#Eval(" mce_href="wineparty.aspx?wineHeaderID=<%#Eval("WinePartyHeaderId") %>" class="we8" style=" text-align:right;">查看详情</a><br /> <b>酒会时间</b>： <%#DataBinder.Eval(Container.DataItem, "ActivityDate", "{0:yyyy-mm-dd}")%>          参加人数： <%#Eval("Quantity")%>人以上<br /> <b>介绍</b>：<%#Eval("Description")%></div> <br /> </div> <div class="wenzi" style="width: 560px; height: 275px; float: left;"> <asp:Repeater ID="Repeater2" runat="server"> <ItemTemplate> <div style="float: left; width: 128px; height: 204px; margin: 20px auto auto 10px;"> <div align="center" style="border: 1px solid #CCCCCC; background: #FFFFFF;" mce_style="border: 1px solid #CCCCCC; background: #FFFFFF;"> <img src='<%#Eval("ImageUrl")%>' alt='<%#Eval("Name")%>' /></div> <div style="background-color: #F9F7F7; text-align: center; color: #333333;" mce_style="background-color: #F9F7F7; text-align: center; color: #333333;"> <%# Eval("Name") %></div> </div> </ItemTemplate> </asp:Repeater> </div> </div> </ItemTemplate> </asp:Repeater> </div>

 

 

 

下面是后台代码的绑定外层Repeater数据方法：

 

---

/// <summary> /// 绑定Repeater数据源 /// </summary> protected void GetBind() { Repeater1.DataSource = BindData(); Repeater1.DataBind(); } ///// <summary> /// 绑定数据源 /// </summary> /// <returns></returns> protected IList BindData() { using (RoalDragonBoatDADataContext ctx = new RoalDragonBoatDADataContext()) { var query_WineParty = from query_wineHeader in ctx.Nop_WinePartyHeader join query_winePlotos in ctx.Nop_WinePartyPhotos on query_wineHeader.WinePartyHeaderId equals query_winePlotos.WinePartyHeaderId //join query_winePartyProduct in ctx.Nop_WinePartyProduct //on query_wineHeader.WinePartyHeaderId equals query_winePartyProduct.WinePartyHeaderId //join query_Product in ctx.Nop_Product //on query_winePartyProduct.ProductId equals query_Product.ProductId //join query_product_picture in ctx.Nop_ProductPicture //on query_Product.ProductId equals query_product_picture.ProductID join query_wineplace in ctx.Nop_WinePartyPlace on query_wineHeader.WinePartyHeaderId equals query_wineplace.WinePartyHeaderId select new { query_winePlotos.WinePartyPhotosId, query_wineHeader.WinePartyHeaderId, wineHeaderName = query_wineHeader.Name, query_wineplace.Quantity, ImageUrlPlotos = query_winePlotos.ImageUrl == null ? "" : "../" + query_winePlotos.ImageUrl, query_winePlotos.Description, query_wineHeader.ActivityDate, //query_Product.Name, //ImageUrlPicture = PictureManager.GetPictureUrl(query_product_picture.PictureID, 200, false) }; return query_WineParty.ToList(); } }

 

 

 

下面是绑定内嵌Repeater数据集方法：

 

---

/// <summary> /// 在项被数据绑定后 ， 绑定内嵌Repeater /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Repeater rpColumnNews = (Repeater)e.Item.FindControl("Repeater2"); string[] newrowv = e.Item.DataItem.ToString().Split(new char[] { ',' }); //提取ID 格式：——>wineHeaderID=1 截取字符串 string wineHeaderID = Convert.ToString(newrowv[1]); int index = wineHeaderID.LastIndexOf("="); rpColumnNews.DataSource = GetNop_WinePartyProduct(int.Parse(wineHeaderID.Substring(index + 1))); rpColumnNews.DataBind(); } } /// <summary> /// 绑定内嵌Repeater数据源 /// </summary> /// <returns></returns> protected IList GetNop_WinePartyProduct(int winePartyHeaderID) { using (RoalDragonBoatDADataContext ctx = new RoalDragonBoatDADataContext()) { var query = (from query_winePartyProduct in ctx.Nop_WinePartyProduct join query_Product in ctx.Nop_Product on query_winePartyProduct.ProductId equals query_Product.ProductId join query_product_picture in ctx.Nop_ProductPicture on query_Product.ProductId equals query_product_picture.ProductID where query_winePartyProduct.WinePartyHeaderId == winePartyHeaderID select new { query_Product.Name, ImageUrl = PictureManager.GetPictureUrl(query_product_picture.PictureID, 200, false) }).Take(4); return query.ToList(); } }

 

 

绑定数据方法，大同小异，大家可以根据自己的需求更改所需方法；

 顺便把Repeater分页方法也粘贴出来吧。希望对大家有帮助！

protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { labPage.Text = "1"; contrlRepeater(); } } //Repeater分页控制显示方法 public void contrlRepeater() { //pb pb1 = new pb(); //DataSet ss = new DataSet(); //ss = pb1.returnDs("select top 200 [标题],[时间] from news"); PagedDataSource pds = new PagedDataSource(); pds.DataSource = BindData(); pds.AllowPaging = true; pds.PageSize = 3; pds.CurrentPageIndex = labPage.Text == "" ? 1 : Convert.ToInt32(this.labPage.Text) - 1; LabCountPage.Text = pds.PageCount.ToString(); labPage.Text = (pds.CurrentPageIndex + 1).ToString(); this.lbtnpritPage.Enabled = true; this.lbtnFirstPage.Enabled = true; this.lbtnNextPage.Enabled = true; this.lbtnDownPage.Enabled = true; if (pds.CurrentPageIndex < 1) { this.lbtnpritPage.Enabled = false; this.lbtnFirstPage.Enabled = false; } if (pds.CurrentPageIndex == pds.PageCount - 1) { this.lbtnNextPage.Enabled = false; this.lbtnDownPage.Enabled = false; } Repeater1.DataSource = pds; Repeater1.DataBind(); BindDropList(); } /// <summary> /// 首页 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void lbtnFirstPage_Click(object sender, EventArgs e) { this.labPage.Text = "1"; DropDownList1.SelectedValue = this.labPage.Text; this.contrlRepeater(); } /// <summary> /// 上一页 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void lbtnpritPage_Click(object sender, EventArgs e) { if (labPage.Text != "") { this.labPage.Text = Convert.ToString(Convert.ToInt32(labPage.Text) - 1); DropDownList1.SelectedValue = this.labPage.Text; } this.contrlRepeater(); } /// <summary> /// 下一页 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void lbtnNextPage_Click(object sender, EventArgs e) { if (labPage.Text != "") { this.labPage.Text = Convert.ToString(Convert.ToInt32(labPage.Text) + 1); DropDownList1.SelectedValue = this.labPage.Text; } this.contrlRepeater(); } /// <summary> /// 末页 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void lbtnDownPage_Click(object sender, EventArgs e) { this.labPage.Text = this.LabCountPage.Text; DropDownList1.SelectedValue = this.labPage.Text; this.contrlRepeater(); }

所有核心代码如上。编译通过，效果正常，如果不当之处，希望大家多多指教。 ok 下班了。吃饭饭~~
