编码实现>ASP.NET验证控件>验证逻辑和思想

指定输入规则，验证用户输入的数据。

输入规则：非空数据，数据值比较，符合正则表达式。

验证顺序：非空数据，转换为正确的数据类型。

 

编码实现>ASP.NET验证控件>非空验证

结果： 我们使用两个RequiredFieldValidator控件，一个用来要求用户必须在下拉框选择选项，另一个要用户必须在文本框输入数据，否则，单击“开始查询”按钮，有出错信息。

编码实现>ASP.NET验证控件>程序控制ASP.NET验证控件

网页加载时，用户未输入数据， 就开始验证。

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                Page.Validate();
            }
        }
