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; }
}
