Question TableAdapterManager contains no connection information

[shinji2000]

I want to save changes that have been made to the dataset. But when I make a change and press save it comes up with an error with this line of code:

Me.TableAdapterManager.UpdateAll(Me.TestDataSet)

The error saids "TableAdapterManager contains no connection information. Set each TableAdapterManager TableAdapter property to a valid TableAdapter instance."

Anyone know whats the problem?

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click         
Me.Validate()         
Me.HelloBindingSource.EndEdit()         
Me.TableAdapterManager.UpdateAll(Me.TestDataSet)     
End Sub
