New to WPF VB, how to access control between window1 and window2 not using mainwindow

[k7s41gx]

Hey Guys,

I am extremely new to VB WPF. I am use to using the old vb6 style. What I am trying to do is access a datagrid control on window2 from window1. I would like to be able to do this the old way as window2.datagrid1 for example. Is there a way to do this? After a TON of googling and not understanding the datacollection thing I have set the datagrid to x:Fieldname="public" but this does not help.


Any idea and / or sample projects to help with this would be greatly appreciated, thanks!


MAINWINDOW LOADS NEW WINDOWS

Private Sub SUPID()
If TextBox1.Text.Length < 2 Then
MessageBox.Show("You need to enter a valid supervisor ID.")
Else
Dim fileName As String = IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "SUP.xlsx")
Dim TextToFind As String = TextBox1.Text ' exists
Dim Value As String = SearchExcelWorkSheet(fileName, "SUP", "U", TextToFind, "B")
If Not String.IsNullOrWhiteSpace(Value) Then
Dim frmload As New Window1
Dim frmload2 As New hidden1
frmload.Show()
frmload.TextBox1.Text = "Welcome " & Value
frmload2.Show()
frmload2.Label1.Content = TextBox1.Text
Me.Hide()
Else
MessageBox.Show("You need to enter a valid supervisor ID.")
End If
End If
End Sub
