ASP.NET : manage and edit users made with "website administration tool"

I have a ASP.NET website that is coded with c# I use Login controls. Now I can Create user & change password with built-in controls. but there is no way to manage and edit users. the only way is "ASP.NET website administration tool" , but there is no control like this tool so we can manage users inside the app.

who can help me? for example is there any code to manage(update) database?
