C#禁止重复提交
1:连续2次提交     Button1.Attributes.Add("onclick",  "this.value='正在提交中，请等待……';this.disabled=true;"   +  this.GetPostBackEventReference(Button1));
2:刷新提交：      Response.Write(" <script   language=javascript> alert( '采购成功 ');window.location.href=window.location.href; </script> ");
也可以做成自定义控件：
   /**//// <summary>
    /// 只能提交一次的按钮
    /// </summary>
    public class ButtonSubmitOnce : Button
    {
        private string _textonclick = "处理中，请稍后。。。";
        private string _clientcheck;
 
        protected override void Render(HtmlTextWriter writer)
        {
            StringBuilder temp = new StringBuilder();
 
            temp.Append(this.OnClientClick);
 
            if (!string.IsNullOrEmpty(_clientcheck)) temp.Append("if(!").Append(_clientcheck).Append(") return false;");
 
            if (!string.IsNullOrEmpty(_textonclick)) temp.Append("this.value=\"").Append(_textonclick).Append("\";");
 
            //this is for the ff
            temp.Append("if(null==window.onunload) window.onunload = function(){};");
 
            temp.Append("this.disabled = true;").Append(Page.GetPostBackEventReference(this));
 
            this.OnClientClick = temp.ToString();
 
            base.Render(writer);
        }
 
        public string TextOnClick
        {
            set { _textonclick = value; }
        }
 
        public string ClientCheck
        {
            set { _clientcheck = value; }
        }
    }
