Auto populate item on addnewitem

Hi

I have a form with a label on it. I want to set the text property when I click on the addnewitem icon on the tool strip. I have the following code on the click event:

Private Sub BindingNavigatorAddNewItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BindingNavigatorAddNewItem.Click
Label1.Text = myvariable
End Sub

However, it seems to run this before refreshing the form, so the variable never gets entered.

Does anyone know how to achieve this?

Thanks
