After changing to White 2.0, I had a problem selecting an item within the WPFComboboxes. The same code, which was working all the time with the version 1.9 does not work anymore. This problem occurs only with the OS Windows XP.
I have used the following code:
public static void SetComboBoxValue(WPFComboBox comboBox,
ListItems items = comboBox.Items; \\-> It is possible to get the items
ListItem item = items.Where( p => p.Text == value ).First();
// wait to open the list with items
AutomationElementHelper.SelectAutomationElement( item.AutomationElement );
