ASP.NET Chat Application

I am开发者_StackOverflow designing an asp.net web application. I need to list all logged in users to a list and click each of them to talk. Which control should I use for listing users? E.g. buttons in listview ? How can I do that ?

I recommend you to create custom user control and add buttons (or any other control) dynamically. Dynamically Create Controls in ASP.NET by Using Visual C# .NET
