I'm using VB.NET 3.5 and I need to add validation checking. Is there a way to require someone to complete certain parts of the form if something is selected? Basically, "if / then" logic?

1 <asp:Panel ID="pnlCallHistory" runat="server" CssClass="pnlFour">
2 <span style="margin: -15px;">
3 <img alt="" src="images/green.gif" height="20px" /></span>
4 <div class= Go to the complete details ...
