I'm getting A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll whenever I try to debug my program, and none of my data is showing up in my DataGridView controls. So far I've only used drag and drop components, so I have no idea what the problem is. I'm using an express edition and it's an access database. Whenever I use preview it shows all the data fine.

This is the code, if that helps:

Code:
Public Class Form1

    Private Sub CustomerBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CustomerBindingNavigatorSaveItem.Click
        Me.Validate()
        Me.CustomerBindingSource.EndEdit()
        Me.TableAdapterManager.UpdateAll(Me.CustomerDataSet)

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'TODO: This line of code loads data into the 'CustomerDataSet.Order' table. You can move, or remove it, as needed.
        Me.OrderTableAdapter.Fill(Me.CustomerDataSet.Order)
        'TODO: This line of code loads data into the 'CustomerDataSet.Customer' table. You can move, or remove it, as needed.
        Me.CustomerTableAdapter.Fill(Me.CustomerDataSet.Customer)

    End Sub
End Class
