ASP.NET中防止重複送出

解決方法：

              .Framework2.0中才有的button屬性：<asp:button id="btnSubmit" onclick="btnSubmit_Click" runat="server"  OnClientClick="this.disabled=true;this.form.submit();" UseSubmitBehavior="False" /> 

            解決重複送出：OnClientClick="this.disabled=true;this.form.submit();" UseSubmitBehavior="False"
