HELP!!! For the life of me I can't figure out how to get my datagrid to update!

[FrustratedNoob]

I've got a database that I've been working on for over a year and a half but I've just recently finished the back end to the point of feeling comfortable with starting on a front end.

So while I've been able to pick up a great deal just stumbling through on my own with the several apress books I've gotten a hold of I've figured out a great deal and have some half decent forms for data entry but for the life of me I can't figure out how to get the databinding to do whatever it does again after having entered data into the database.

My problem placed more concisely

My form's data grid populates from a stored procedure via a binding source.

My form's button then uses another stored procedure to enter in the data into the database.

What I want to do is have the datagrid recall the stored procedure and refresh the grid with the newly modified data included.

This is what I've been racking my brain over for some time, and scouring the internet and my various apress books for, is figuiring out why none of my attempts at doing this are working.

I'm just finding most all of the stuff out there about datagrids and the such are not at all tailored towards a person trying to do all their interactions via stored procedures. I know I can do the basics, and the forms work and I know that if I just close the form and access it manually again that the datagrid reloads with the newly input data, but I'm really trying to get it so that I'm making a UI that is as easy to use as I can get it.


I'd appreciate it if you, or anyone, could point out what I'm doing wrong, or not doing right, or both.

Sorry the code is so weird here. I accidentally posted this question in the old vb land.

Here's a link if you want a prettier view of the code--
