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
