很简单，后台得到一个随机数a,保存到session中，页面上弄个隐藏值b，每次执行数据操作时，比较 a==b（true执行操作），自己在网上找的代码已经测试通过
哪位大虾有更好的解决方案不妨指点下啊。本人菜鸟一个
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<%#Eval("zname") %><br />
</ItemTemplate>
</asp:Repeater>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:Button ID="SubmitButton" runat="server" Text="Button" OnClientClick="return check()" onclick="Button1_Click" />

else

// do your processing here to avoid Refresh trap
