Is it possible to reuse a window?

[bigfoot]

I have a form that calls another form on the fly and it loads dynamic content out of the database.
When formA calls formB, it passes in the key to the table and the data is loaded.
You know how we do Dim f as form in VB.NET?

Is this something like this in ASP.NET?

formA and forM are the same form.

Did I explain this correctly?

Thanks for any and all help.

I used a Javascript function and it's working.
