VS2005移动Web窗体中RegularExpressionValidator的诡异现象

我的本意是判断textbox中输入的字符串是否符合时间日期yyyy-MM-dd HH:mm格式
可是当我输入错误的格式时Command1_Click中的代码仍然会执行！这意味这程序先执行了Command1_Click中的代码才去判断textbox中的格式不正确！
那位大哥大姐能告诉我这是怎么回事，见鬼了@！@@！

  1.   

    你的验证组呢？<mobile:RegularExpressionValidator ID="RegularExpressionValidator1" Runat="server"
                ControlToValidate="TextBox1" ErrorMessage="格式错误！" ValidationExpression="^(\d{4})(-)(\d{2})(-)(\d{2})(\s+)(\d{2})(:)(\d{2})$" ValidationGroup="T"><mobile:Command ID="Command1" Runat="server" OnClick="Command1_Click" ValidationGroup="T" >Command</mobile:Command>

    我使用的是移动web控件，command的属性面板里边没有ValidationGroup属性
