Examples

Here's how to add placeholder text to a ComboBox.

<ComboBox Header="Colors" PlaceholderText="Pick a color">
    <x:String>Blue</x:String>
    <x:String>Green</x:String>
    <x:String>Red</x:String>
    <x:String>Yellow</x:String>
</ComboBox>

Remarks

The placeholder text is shown when the SelectedIndex is -1 and the SelectedItem is null. (These two properties are kept in sync.) A user can't display the placeholder text once an item has been selected. However, you can programmatically set either the SelectedIndex to -1 or the SelectedItem to null to cause the placeholder text to be shown again.
