Remarks

The PropertyCondition class is suitable for checking property values on the control that contains the MultiTrigger that contains it. To check values on other controls, developers can use the BindingCondition class, in addition to any property conditions in the trigger list.

The XML example below creates a property condition within a surrounding MultiTrigger within a TextCell that turns the text green when the secret is typed. The code is turned back to the default color if the user then edits the secret. (Typically, a MultiTrigger would have more than one condition; this example is simplified for clarity.)

<Entry Placeholder="Type the secret!"
       VerticalOptions="Center"
       HorizontalOptions="Center">
<Entry.Triggers>
<MultiTrigger TargetType="Entry" >
<MultiTrigger.Conditions>
<PropertyCondition Property="Text"
                                     Value="The text color is green" />
</MultiTrigger.Conditions>
<Setter Property="TextColor"
                  Value="Color.Green" />
</MultiTrigger>
</Entry.Triggers>
</Entry>
