What errors are you getting?

Ok, the reason you are not getting info is that when you post back, the control does not exist. You need to rebuild the control again...

So, instead of building your control in the button event, try to put in your Page_Load a call to build your drop down list and add the content...

Then your button_2 will get the info...

I hope this makes sense....
