asp.net防止页面重复提交

解决方法一：

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

            解决重复提交：OnClientClick="this.disabled=true;this.form.submit();" UseSubmitBehavior="False"

解决方法二：

             this.btnSubmit.Attributes["onclick"] = this.GetPostBackEventReference(this.btnSubmit) + ";this.disabled=true;";     //防止重复提交
