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>    
        <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);
            }
