[RESOLVED] Getting bound ComboBox selected item text

[wolf99]

Hi Folks

I have a Combobox populated with MAC address strings from a SQL server DB (using Entity Framwork)

Public Class Form1
    Dim myContext As New MySqlDataEntities
    Dim burnRackBay As New BurnRackBay
 
    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        ComboBox1.DataSource = myContext.BurnRackBays
        ComboBox1.DisplayMember = "Mac"
        ComboBox1.SelectedIndex = -1
    End Sub

However when getting the text of the selected item to use in a new L2E query the only way that seems to work is to use ComboBox.Text

Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
        If ComboBox1.SelectedIndex >= 0 Then
            Label4.Text = ComboBox1.Text
        End If
    End Sub

But when I do this, when the form loads the label text is immediately set to the first item in the list instead of just being left blank, as the ComboBox is (as I set its index to -1 in Form1.Load)

Is there a better way of getting the selected string, that is the *actual* string *currently* selected

EDIT: Just noted that this does not occur if I remove the If from the selectedIndexChanged event... does this mean that the event is firing on form load but before the form.load event sub runs?
