Repeater中绑定DropDownList和使用RepeaterItem

还是正在做的项目中遇到了使用Rpt的问题。查过MSDN后得到解决。

以前的后台系统用到了大量的GridView,前台都是Repeater。现在后台也用Repeater了～

代码如下：

ASPX:

       <asp:UpdatePanel ID="UpDPanelRptNews" runat="server" ChildrenAsTriggers="true" UpdateMode="Always">

          <ContentTemplate>

            <asp:Repeater ID="RptNew" runat="server" onitemdatabound="RptNew_ItemDataBound">

            <HeaderTemplate>

                <table border="0" align="center" cellpadding="1" cellspacing="1" width="580px" class="UserTable">

                  <tr class="UserTableRow2"><td width="150px"><b>标题</b></td><td width="80px"><b>作者</b></td><td width="75px"><b>类型</b></td><td width="75px"><b>是否显示</b></td><td width="100px"><b>删除</b></td></tr>     

            </HeaderTemplate>

            <ItemTemplate>

               <tr onmouseover="c=this.style.backgroundColor;this.style.backgroundColor='#00A9FF'" onmouseout="this.style.backgroundColor=c"><td width="150px"><a href='Admin_News.aspx?id=<%# Eval("id") %>' title='<%# Eval("title")+"["+Eval("adddate")+"}" %>'><%# WebFunction.StrHelper.CutStringMit(Eval("title").ToString(),20) %></a></td><td width="80px"><%# Eval("addname") %></td><td width="75px"><%# Eval("flag").ToString()=="1"?"动态":"新闻" %></td>

               <td width="75px">

               <asp:DropDownList ID="DListNewsIsShow" runat="server" AutoPostBack="true" OnSelectedIndexChanged="DListNewsIsShow_SelectedIndexChanged">

                  <asp:ListItem Value="1">是</asp:ListItem>

                  <asp:ListItem Value="0">否</asp:ListItem>

               </asp:DropDownList><asp:Label ID="LabId" runat="server" Visible="false" Text='<%# Eval("id") %>'></asp:Label>

               </td>

            </ItemTemplate>

            <FooterTemplate></table></FooterTemplate>

            </asp:Repeater>

           </ContentTemplate>

         </asp:UpdatePanel> 

 

CS:

        //遍历Rpt中DListNewsIsShow的数据读取

        protected void RptNew_ItemDataBound(object sender, RepeaterItemEventArgs e)

        {

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

            {

                DataRowView rowv = (DataRowView)e.Item.DataItem;

                DropDownList DListNewsIsShow = (DropDownList)e.Item.FindControl("DListNewsIsShow");

                DListNewsIsShow.Items.FindByValue(rowv["isshow"].ToString()).Selected = true;

            }

        }

               

        //异步更新新闻是否显示

        protected void DListNewsIsShow_SelectedIndexChanged(object sender, EventArgs e)

        {

            DropDownList DListFNewsIsShow = sender as DropDownList;

            RepeaterItem item = DListFNewsIsShow.Parent as RepeaterItem; //转为所在Item

            Label LabFId = item.FindControl("LabId") as Label;　　//查找

 

            NewsInfo newsInfoRpt = new NewsInfo();

            newsInfoRpt.Id = LabFId.Text.ToString();

            newsInfoRpt.IsShow = Convert.ToInt16(DListFNewsIsShow.SelectedValue.ToString());

            if(news.Update(newsInfoRpt,"1")<=0)

            {

                ScriptManager.RegisterStartupScript(UpDPanelRptNews, typeof(UpdatePanel), "JsAlert", "alert('对不起，更新失败！!')", true);

            }

        }
