Help with Saving data in a combobox in a datarepeater

I Have a Datarepeater on my Form that has a Label and a Combobox.

The Combobox has two items IN & OUT. I want the data to update when the user changes the Current value.

There is a save button on the toolbar (auto generated toolstrip) but I dont want the user to have to click that everytime.
that button causes the following command.

Me.TableAdapterManager.UpdateAll(Me.NewDBADataSet)

I Tried,
SelectedIndexChanged & SelectedValueChanged

the Selected index change seems to only work if the user moves to the next item in the datarepeater and changed that combobox.

Help
