HeaderTemplate

前台代码：

<asp:Repeater runat="server" onitemdatabound="doSomething">
<HeaderTemplate>
<table border="0" cellspacing="0" cellpadding="0" class="ltable">
  <tr>
    <th width="8%">选择</th>
  </tr>
</HeaderTemplate>
<ItemTemplate>
  <tr>
    <td align="center">
      <asp:CheckBox CssClass="checkall" runat="server" />
      <asp:HiddenField Value='<%#Eval("id")%>' runat="server" />
    </td>
  </tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>

后台代码：

1.绑定数据：

DataSet source = bll.GetList(.......);

rptList.DataSource = source;
 rptList.DataBind();

2.操作 单选框

var selectCount=0;//选中了几个

var count=0;//选中值

   for (int i = 0; i < rptList.Items.Count; i++)
            {
                int id = Convert.ToInt32(((HiddenField)rptList.Items[i].FindControl("hidId")).Value);//隐藏域中的值
                CheckBox cb = (CheckBox)rptList.Items[i].FindControl("chkId");//单选
                if (cb.Checked)
                {
                selectCount++;

　　　　　　count+=id;

}
            }

 3.onitemdatabound 绑定数据后的方法

protected void doSomething(object sender, RepeaterItemEventArgs e)//Repeater控件 e
        {

  if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
            {
                HiddenField hidLayer = (HiddenField)e.Item.FindControl("hidId");//获取控件

                int classLayer = Convert.ToInt32(hidLayer.Value);
            }}
