ComboBox.FindString will return the index of an item that matches.

See if this helps.

If combox1.FindString("The String To Search") < 0 Then
            combox1.Items.Add("The String To Search")
        End If

Thanks for your valuable sharing of combobox add items.

The following will add "some text" to the combo box only if it doesn't already exist.

Dim text As String = "some text"

If Not ComboBox1.Items.Contains(text) Then
End If
