              .Framework2.0中才有的button属性:
C#代码 复制代码
  1. <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"
