When one drags a column from a datasource onto a form, VB.NET kindly creates a ToolStrip at the top of the form with useful controls like Next, Previous, Add, Delete and Save. However, it only writes the code for Save to the form, e.g.

Private Sub TableNameBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TableNameBindingNavigatorSaveItem.Click

       Me.Validate()
       Me.TableNameBindingSource.EndEdit()
       Me.TableNameTableAdapter.Update(Me.DataSetName.TableName)

End Sub

I needed to write code to emulate the ToolStrip's behaviour when clicking on the Add symbol, and came up with:

Dim DefaultDate1 As Date
DefaultDate1 = Now
Me.TableNameTableAdapter.Insert("", "", "", "", "", DefaultDate1, "", "")
Me.TableNameBindingSource.AddNew()

Is that correct? If not, how can I see the code used by each of the items in the ToolStrip container? I've tried the Edit Items option, but I couldn't find it there.

Finally, does the Delete method of a table adapter really require ALL the columns as parameters?

Thanks,
David.
