Repeater控件想必熟悉.net web开发的人员是很了解不过的了，接下来将与大家共同学习下它的全选删除和分页，感兴趣的你可不要错过了哈，希望可以帮助到你
代码如下:
<script type="text/javascript">
function SelectAll(box)
{
for(var i=0;i <document.form1.elements.length;i++)
{
var e=document.form1.elements[i];
if((e.type=='checkbox'))
{
var o=e.name.lastIndexOf('cbx');
if(o!=-1)
{
e.checked=box.checked;
}
}
}
}
</script>
<body>
<form id="form1" runat="server">
<div>
</div>
<asp:Repeater ID="Repeater1" runat="server">
<HeaderTemplate>
<table>
<tr><th><input id= "chkHeader" type= "checkbox" onclick= "SelectAll(this)"/>全选</th><th>报到号</th><th>考生号</th><th>姓名</th><th>身份证号码</th><th>家庭地址</th><th>类别</th><th>专业</th></tr>
</HeaderTemplate>
<ItemTemplate>
<tr><td align="center" ><asp:CheckBox ID="cbx" runat="server" /></td><td><asp:Label id="lbl" Text='<%#Eval("id") %>' runat="server" ></asp:Label></td><td><%#Eval("ksh") %></td><td><%#Eval("xm") %></td><td><%#Eval("sfzh") %></td><td><%#Eval("jtdz") %></td><td><%#Eval("jhxzmc") %></td><td><%#Eval("lqzy") %></td></tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
<br />
<asp:Button ID="btnDel" runat="server" onclick="btnDel_Click" Text="批量删除" OnClientClick="return confirm('确定要删除吗？该操作不可恢复！！！')" />
<br />
<br />
<webdiyer:AspNetPager ID="benren" runat="server" pagesize="2"
CssClass="anpager" onpagechanged="AspNetPager1_PageChanged"
FirstPageText="首页" LastPageText="尾页" NextPageText="下一页" PrevPageText="上一页"
ShowMoreButtons="False" ShowPageIndexBox="Never" AlwaysShow="True">
</webdiyer:AspNetPager>
</form>
</body>
