Is there any way to highlight comboboxitem programmatically?
Property IsHighlighted has no setter((. Changing style is not enought.
回答1:
If you goal is to select rather than highlight (the IsHighlighted property is used to indicate a selected item), you can just set the IsSelected property or the SelectedItem or SelectedValue of the parent ComboBox.
