Adding Data Using Data Details View?

I have a datagridview on form1 but I don't want users adding data using datagridview, instead, I wanna use details view. So I created a form2, dragged and dropped details view on form2. I changed the Addnew on BindingNavigator to None and added a code to the Addnew click event handler to call the form2 out so that I could add data from there. But, when form2 loaded. the textboxes pulled out all the information from datagridview. I did not want that, I wanted all the textboxes to appear empty when it was loaded. so I deleted all the textboxes and added my own textboxes so that they appeared empty when form2 was loaded.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.VendorTableAdapter.Insert(TextBox1.Text, TextBox2.Text, TextBox3.Text, TextBox4.Text)
Me.VendorTableAdapter.Fill(Me.VendorDataSet.vendor)
End Sub

I added the above code to allow users to add data into datagridview using data details view.
