Nothing wrong with that youe code is fine, perfect, so use it. the dataset is the name of the dataset named by you when wizarding it. I post my code for you to see:
Private Sub StudentBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StudentBindingNavigatorSaveItem.Click
End If
Me.Validate()
Me.StudentBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.SalvadorSystemDataSet) my dataset is different from the studentbindingsource....works fine. that the name of my database, the all table reference....
Don't judge me, just Upgrade me. Thanks!
