there is some validator control available...

XML

<ASP:RequiredFieldValidator> 
<ASP:CompareValidator>
<ASP:RangeValidator> 
<ASP:RegularExpressionValidator> 
<ASP:CustomValidator> 
<ASP:RequiredFieldValidator>
<ASP:ValidationSummary>

ASP.NET Validation Controls[^]

XML

<form runat="server">
Name: <asp:TextBox id="name" runat="server" />
<br />
Age: <asp:TextBox id="age" runat="server" />
<br /><br />
<asp:Button runat="server" Text="Submit" />
<br /><br />
<asp:RequiredFieldValidator
ControlToValidate="name"
Text="The name field is required!"
runat="server" />
</form>
