In Asp.net 1.1, it is very troublesome for verification controls when they are used, that is, it is impossible to choose to verify some controls, in Asp.net 2.0, the validationgroup attribute is added and some controls can be verified. The example is as follows:

<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>
