AJAX.NET中的UpdatePanel问题
这是我的代码:
<asp:ScriptManager ID= "ScriptManager1 " runat= "server " />
<div>
<asp:UpdatePanel ID= "UpdatePanel1 " runat= "server ">
<ContentTemplate>
<asp:Label ID= "Label1 " runat= "server "> </asp:Label> <br />
<br />
<asp:Button ID= "Button1 " runat= "server " Text= "Button " OnClick= "Button1_Click " />
</ContentTemplate>
</asp:UpdatePanel>
<asp:UpdatePanel ID= "UpdatePanel2 " runat= "server ">
<ContentTemplate>
<asp:Label ID= "Label2 " runat= "server "> </asp:Label>
<br />
<br />
<asp:Button ID= "Button2 " runat= "server " OnClick= "Button2_Click " Text= "Button " />
</ContentTemplate>
</asp:UpdatePanel>
</div>
<br />
<asp:UpdateProgress ID= "UpdateProgress1 " runat= "server ">
<ProgressTemplate>
