Asp.Net Repeater的两层嵌套以及遍历取值的简单实现

  <select id="s6" multiple="multiple">
                <asp:Repeater ID="rpl_dept" runat="server" 
                    onitemdatabound="rpl_dept_ItemDataBound">
                <ItemTemplate>
                <optgroup label="<%#Eval("Name") %>">
                    <asp:Repeater ID="rpl_user" runat="server">
                    <ItemTemplate>
                    <option><%#Eval("Name")%></option>
                    </ItemTemplate>
                    </asp:Repeater>
                    </optgroup>
                </ItemTemplate>
                </asp:Repeater>
            </select>       

   protected void rpl_bind()
        {
            com.hmby.BLL.Depts dept = new com.hmby.BLL.Depts();
            string strWhere = "";
            DataTable dt = new DataTable();
            dt = dept.GetList(strWhere).Tables[0];
            if (dt.Rows.Count > 0)
            {
                this.rpl_dept.DataSource = dt;
                this.rpl_dept.DataBind();
            }
         }

         protected void rpl_dept_ItemDataBound(object sender, RepeaterItemEventArgs e)
         {
             if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
             {
                 Repeater rep = e.Item.FindControl("rpl_user") as Repeater;//找到里层的repeater对象
                 DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项 
                 int deptId = Convert.ToInt32(rowv["Id"]); //获取填充子类的id 
                 DataTable dt = new DataTable();
                 com.hmby.BLL.Users user = new com.hmby.BLL.Users();
                 string strWhere = " DeptId=" + deptId;
                 dt = user.GetList(strWhere).Tables[0]; ;
                 if (dt.Rows.Count > 0)
                 {
                     rep.DataSource = dt;
                     rep.DataBind();
                 }
               
             }

         }

另外一种嵌套的前台(表格)(下边是遍历)

<asp:Repeater ID="rpl_mParent" runat="server"
                        onitemdatabound="rpl_mParent_ItemDataBound">
    <ItemTemplate>
        <tr>
            <td style="vertical-align:top;background-color:#ffa !important;">
            <input type="checkbox" id="cbox_p" value='<%# Eval("Id")%>' runat="server"/>
      <label class="choice" for="cb1"><%# Eval("ModelName")%></label>
            </td>
        </tr>
        <asp:Repeater ID="rpl_mChild" runat="server">
        <ItemTemplate>
        <tr><td>&nbsp;&nbsp;&nbsp;&nbsp;
        <input type="checkbox" id="cbox_c" value='<%# Eval("Id")%>' runat="server"/>
     <label class="choice" for="cb1"><%# Eval("ModelName")%></label>
        </td></tr>
        </ItemTemplate>
        </asp:Repeater>
    </ItemTemplate>
    </asp:Repeater>

遍历嵌套的Checkbox，双层遍历

for (int i=0;i<this.rpl_mParent.Items.Count;i++)
            {
                HtmlInputCheckBox cbox_p = (HtmlInputCheckBox)rpl_mParent.Items[i].FindControl("cbox_p");
                if (cbox_p.Checked)
                { 
                    //选中了checkbox_p
                    JsUtil.Alert(this, "p");
                }
                Repeater rplChild = (Repeater)rpl_mParent.Items[i].FindControl("rpl_mChild");
                string c = "";
                for (int j=0;j<rplChild.Items.Count;j++)
                {
                    HtmlInputCheckBox cbox_c = (HtmlInputCheckBox)rplChild.Items[j].FindControl("cbox_c");
                    if (cbox_c.Checked)
                    { 
                        //选中了checkbox_c
                        c += cbox_c.Value + ",";
                    }
                }
                JsUtil.Alert(this, c);
            }
