SetSelectedItem doesnt jump to selected item after clicking the box
<p>I have a combobox which I fill and pick the needed item with selectedItem but not with selectedIndex.</p>

<p>In case of selectedIndex it sets the needed value in the combobox, and highlights the selection. but in case of selectedItem it selects what I need, but when i press the box it shows list from the very begining.</p>

<p>how to set the selected item without using the setSelectedIndex ?</p>
