Drop Down List Criteria for Data in DataGrid in Web App

Hi all,

First of all, I'm totally new to VB.net, but have used VB6 for a good while.

I started playing with making a web application where a combo drop down list is loaded with values from SQL Server. Then the user can choose a value and the datagrid on that same form should be populated using that value as criteria.

The problem is that when a user chooses a value in the drop down list, nothing happens.

I tried adding a simple command in the SelectedIndexChanged (I think that's what it was) to update the text in a label and it does not fire.

Do I have to use a button or something to fire the my update datagrid routine? Do I need two forms, one with the drop down box and the other with the datagrid and need to somehow post this to it? (Which I have no idea how) Is there something else I need to change or add to get it to work?

Thanks very much!
