aspx页面代码：

<input type="button"  onclick='<%=string.IsNullOrEmpty(OnClientSubmit)?"retrun false;":string.Format("if({0}) {0}(submitData());return false;",OnClientSubmit)%>' alt="确定" />

aspx.cs后台代码：

        public string OnClientSubmit

        {

            get

            {

                if (ViewState["OnClientSubmit"] != null)

                {

                    return ViewState["OnClientSubmit"].ToString();

                }

                else

                {

                    return "";

                }

            }

            set { ViewState["OnClientSubmit"] = value; }

        }
