VS 2010 Tables Database Question

I needed that my database would update instantly after i input a name to the textbox2.text

i use this code..
StudentTableAdapter.Insert(TextBox2.Text)

but i need to close the form to able to see the "after result"
what i need is how can i sort of refresh the database instantly so when i input a text it
add up instantly...

ps: i dont want to use the bindingnavigationadditem on the above panel but it works that way
