Search a listview for an item already in the list.

Hi All,

I am using a KeyPress event to place the textbox.text into the listbox but only if it does not exist. It just keeps adding the same named item even though it is in the list, probably something simple. Here is my code:
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
            Dim strg As String = txtAddUnit.Text
            Dim item As ListView.ListViewItemCollection = ltvUnits.Items
            Dim index As Integer
            If ltvUnits.Items(index).Text = strg Then
                Exit Sub
            Else
                ltvUnits.Items.Add(strg).BackColor = Color.LightGreen
                UnitTrackingPanel2()
                txtAddUnit.Text = String.Empty
            End If
        End If

try this...
    Private Sub txtAddUnit_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtAddUnit.KeyPress
        If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
            If ltvUnits.FindItemWithText(txtAddUnit.Text) Is Nothing Then
                ltvUnits.Items.Add(txtAddUnit.Text).BackColor = Color.LightGreen
                UnitTrackingPanel2()
                txtAddUnit.Text = String.Empty
            End If
        End If
    End Sub
