BaseTrigger Class
Represents the base class for specifying a conditional value within a Style object.
The styling and templating model allows you to specify triggers within your Style, ControlTemplate, and DataTemplate. Essentially, TriggerBase is the base class for objects that allow you to apply changes when certain conditions (such as when a certain property value becomes true, or when an event occurs) are satisfied.

Methods
From DependencyObject
Name | Description |
---|---|
ClearAnimation | Clears the animation value of a property |
ClearAnimation | Clears the animation value of a property |
ClearLocalValue | Clears the local value of a property The property to be cleared is specified by a DependencyProperty identifier |
CoerceValue | Coerces and validates the effective property value |
CoerceValue | Coerces and validates the effective property value |
DependencyPropertyChanged | Returns the PropertyChanged event |
GetBaseValue | Returns the base value without animation nor coerce (this never returns IExpression like GetLocalValue) |
GetLocalValue | Returns the local value of a dependency property, if it exists. |
GetValue | Returns the current effective value of a dependency property on this instance of a DependencyObject |
GetValueObject | Returns the current effective value of a dependency property on this instance of a DependencyObject as a boxed value |
GetValueProvider | Gets the provider that returns the effective value for the specified dependency property |
HasAnimatedProperties | Returns true if there is any animated property |
InvalidateProperty | Re-evaluates the effective value for the specified dependency property if necessary If null is passed, a full re-evaluation could be needed |
IsCached | Returns if the value is stored in the cache. If true, the priority is returned in the provider field |
SetAnimation | Sets the animated value of a property |
SetCurrentValue | Sets the current value of a dependency property. The current value is set on the coerce field, without modifying source or animated value |
SetCurrentValueObject | Sets the current value of a dependency property using a boxed value |
SetExpression | Sets the expression to be evaluated dynamically to obtain the value of the property |
SetValue | Sets the local value of a dependency property |
SetValueObject | Sets the local value of a dependency property using a boxed value |
