I need to use on of the following properties to programaticallly select a value in a combobox:
SelectedItem
SelectedIndex
SelectedText
SelectedValue

The properties DisplayMember and ValueMember are for binding to datasources.

Those two properties are for data source binding. Both properties expect references to datasource field properties, and you wont be able to get the functionality that you are looking for with a standard combobox in that manner.
However, you could use something like:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If ComboBox1.Text = "Assigned" Then ComboBox1.Text = 5000
End Sub

To add "Assigned" to your combobox:
ComboBox1.Items.Add("Assigned")
To select it :
ComboBox1.SelectedItem = "Assigned"

This example does what you are talking about. It creates a datatable, populates it with Name/Value pairs, and then binds it to the combobox. When the user selects one of the bound items, a msgbox displays its selectedvalue.
To test it, create a form, add a button and a combobox, and paste it in. If you have any questions let me know.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 
        Dim dt As New DataTable("ValuePairs")
        dt.Columns.Add("Name")
        dt.Columns.Add("Value", GetType(Integer))
 
        For i = 1 To 10
            Dim nr As DataRow = dt.NewRow
            nr("Name") = "Item " & i
            nr("Value") = i * 16
            dt.Rows.Add(nr)
        Next
        dt.AcceptChanges()
 
 
        With ComboBox1
            .DataSource = dt
            .DisplayMember = "Name"
            .ValueMember = "Value"
        End With
    End Sub
    Private Sub ComboBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.TextChanged
        If IsNumeric(ComboBox1.SelectedValue) Then
            MsgBox(ComboBox1.SelectedValue)
        End If
    End Sub
