dkloeck - I know I can do that on the button click but I would like to use the validation controls for this - Do I need to use a custom validator then or is there a way to do it with the Required field validator?

It works fine. I decided to enable and disable the Continue button based on the lstBox.Items.Count rather than use the Validators. &nbsp;Thanks

I have two listboxes on an asp.net page. The first one is a multiselect that allows the user to select specific employees. &nbsp;They can then move their selected employees (via a button click) to the other listbox. &nbsp;Pretty standard fare and that all works fine. &nbsp; Before they click continue, I want to make sure there are employees in the second listbox and it is not empty. &nbsp;How would I validate that? &nbsp;Can I use a required field validator somehow or would I need a custom validator? &nbsp;Please be specific.<br />

Thanks in advance

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
