This may be a stupid question, but I'm fairly new at this.

Anyway I have this form where I display data from my database. I use a generic list for this.

I also have an area on the same form where I can add items to my database. So when I click my Save button I also want to clear the generic and 'recall' the data, so the things I added will also be displayed.

However this won't work when put all the code for this in the Save button. I can add things to the database, but refreshing the data doesn't work.
When I use a second button, with which I clear the generic list and recall the data, after I added something, it does work.

Is there a way to do all this with the same button?
