I have another problem.

I can select a contact in the dropdown by it it´s telephone number

Code:
Me.listbox1.SelectedValue = "555-125-4587"
But I cannot select a contact in the dropdown by it´s name.

Code:
Me.listbox1.SelectedItem = "John Doe"
When I try this, the dropdown stays at the current selected entry.

Can you help me again bmahler? Thank you...
