在ASP.net 1.1中,对于验证类控件,在使用时,遇到有的不需要验证的控件时,是十分麻烦的,就是说不可能有选择验证某些控件,而在ASP.net 2.0中,新增加了validationgroup属性,可以指定验证某些控件,例子如下:
<HTML>
<body>
<form runat=“server”>
<ASP:textbox id=“TextBox1” runat=“server”/>
<ASP:requiredfieldvalidator ValidationGroup=“Group1”
ErrorText=“Need to Fill in Value!”
ControlToValidate=“TextBox1”
runat=“server”/>
<ASP:textbox id=“TextBox2” runat=“server”/>
<ASP:requiredfieldvalidator ValidationGroup=“Group2”
ErrorText=“Need to Fill in Value!”
ControlToValidate=“TextBox2”
runat=“server”/>
<ASP:button text=“Group1” ValidationGroup=“Group1” runat=“server”/>
<ASP:button text=“Group2” ValidationGroup=“Group2” runat=“server”/>
</form>
</body>
</HTML>
