public sealed class BindingCondition : Xamarin.Forms.Condition, Xamarin.Forms.Xaml.IValueProvider

    inherit Condition
    interface IValueProvider

Inheritance: System.Object

Condition
BindingCondition

Attributes: AcceptEmptyServiceProviderAttribute

Implements: IValueProvider

Remarks

The BindingCondition class can compare a value a binding on any class within the current scope. Developers who want to compare to a value to a bound property on the control that contains the conditions surrounding MultiTrigger may want to use a PropertyCondition in addition to any binding conditions in the trigger list.

The XML example below creates a binding condition within a surrounding MultiTrigger (omitted) that succeeds when the referenced name has a Text.Length property length that is equal to 0. (name must refer to an element, such as a TextCell, that has a Text property that, in turn, has a Length property.)

<BindingCondition Binding="{Binding Source={x:Reference name},
                                Path=Text.Length}"
                                Value="0" />
