I have an identical action that needs to occur as in ID: 41772683 but this one uses listboxes. I have made the search boxes at the top populate according to whats typed in the CW column (using the search option bottom right)  but I cannot see how to emulate the enter keypress across the other columns programatically.

here is the first columns key up within this the search occurs

 Private Sub OnKeyUpCW(sender As Object, e As KeyEventArgs) Handles TextSearchCW.KeyUp, ListCW.KeyUp
        Dim index = -1

        If OPTagIndependant.Checked = True Then


        Else

            TextSearchAbi.Text = TextSearchCW.Text
            TextSearchCap.Text = TextSearchCW.Text
            TextSearchGlass.Text = TextSearchCW.Text
            TextSearchTvi.Text = TextSearchCW.Text

        End If

        If TypeOf sender Is TextBox Then
            Dim tb = DirectCast(sender, TextBox)
            If tb.Equals(TextSearchCW) Then
                If e.KeyCode.Equals(Keys.Enter) Then
                    index = ListCW.FindString(tb.Text)
                    If index <> -1 Then
                        ListCW.SetSelected(index, True)
                    End If
                    tb.Clear()
                    e.Handled = True
                End If
            End If
        ElseIf TypeOf sender Is ListBox Then
            Dim lb = DirectCast(sender, ListBox)
            If lb.Equals(ListCW) Then
                If e.KeyCode.Equals(Keys.Enter) Then
                    index = lb.FindString(TextSearchCW.Text)
                    If index <> -1 Then
                        lb.SetSelected(index, True)
                    End If
                    TextSearchCW.Clear()
                    e.Handled = True
                ElseIf e.KeyCode.Equals(Keys.Back) Then
                    If TextSearchCW.Text.Length > 0 Then
                        TextSearchCW.Text = TextSearchCW.Text.Substring(0, TextSearchCW.Text.Length - 1)
                    End If
                Else
                    TextSearchCW.Text = TextSearchCW.Text + Convert.ToChar(e.KeyCode)
                End If
            End If
        End If
    End Sub

Each of the others are within their own key up event.
    Private Sub OnKeyUpAbi(sender As Object, e As KeyEventArgs) Handles TextSearchAbi.KeyUp, ListAbi.KeyUp
        Dim index = -1
        If TypeOf sender Is TextBox Then
            Dim tb = DirectCast(sender, TextBox)
            If tb.Equals(TextSearchAbi) Then
                If e.KeyCode.Equals(Keys.Enter) Then
                    index = ListAbi.FindString(tb.Text)
                    If index <> -1 Then
                        ListAbi.SetSelected(index, True)
                    End If
                    tb.Clear()
                    e.Handled = True
                End If
            End If
        ElseIf TypeOf sender Is ListBox Then
            Dim lb = DirectCast(sender, ListBox)
            If lb.Equals(ListAbi) Then
                If e.KeyCode.Equals(Keys.Enter) Then
                    index = lb.FindString(TextSearchAbi.Text)
                    If index <> -1 Then
                        lb.SetSelected(index, True)
                    End If
                    TextSearchAbi.Clear()
                    e.Handled = True
                ElseIf e.KeyCode.Equals(Keys.Back) Then
                    If TextSearchAbi.Text.Length > 0 Then
                        TextSearchAbi.Text = TextSearchCW.Text.Substring(0, TextSearchAbi.Text.Length - 1)
                    End If
                Else
                    TextSearchAbi.Text = TextSearchAbi.Text + Convert.ToChar(e.KeyCode)
                End If

You could call the OnKeyUpXXX methods and pass the arguments you want.
