Answer 1

Then you should create a class to represent the items in the ComboBox:
Public Class MyItem
Public Property PartA As String
Public Property PartB As String
End Class
...and add instances of this class to the ComboBox:
Try
Dim mydocpath1 As String = Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
Dim mylines() As String = File.ReadAllLines(mydocpath1 + "\TextFile1.txt")
For Each line In mylines
Dim parts() As String = line.Split(","c)
Dim item As MyItem = New MyItem With {.PartA = parts(0), .PartB = parts(1)}
cmb1.Items.Add(item)
Next line
cmb1.SelectedItem = cmb1.Items(1) 'select second item
Catch ex As Exception
MsgBox(ex.Message)
End Try
Then you set the DisplayMemberPath of the ComboBox to the name of one property and bind the Text property of the TextBlock to the other one:
<ComboBox Name="cmb1" DisplayMemberPath="PartA" />
<TextBlock Text="{Binding ElementName=cmb1, Path=SelectedItem.PartB}" />
That should solve your issue.
