XamlTimers

WPF behaviors that update bindings or execute a callback method on a configurable interval.
You can toggle the timers at any time; or even bind the EnableTimer property to another control, such as a CheckBox.

Usage

Requires Microsoft's WPF Behaviors NuGet package:

• Microsoft.Xaml.Behaviors.Wpf (GitHub, NuGet)

To use the above package in XAML, add this namespace to your Window:
http://schemas.microsoft.com/xaml/behaviors

Namespace

C#

using XamlTimers;

XAML

xmlns:behavior="clr-namespace:XamlTimers;assembly=XamlTimers"

Behaviors

Properties that don't have default values are required!

IntervalUpdateBinding

Properties

Property	Type	Default Value	Description
EnableTimer	bool	true	When true, the timer is enabled & the specified binding is updated every time the Interval has elapsed; When false, the timer is disabled & no updates occur.
Interval	double		The timer interval, in milliseconds.
Property	DependencyProperty		Specifies the target property of the attached object to update the databinding on. This should be specified in the form "{x:Static <CONTROL>.<PROPERTYNAME>Property}", where the <CONTROL> is the control that defines the property, not the control that inherits it. (i.e. Slider.Value => RangeBase.ValueProperty)
ThrowWhenPropertyIsNull	bool	true	When true, an ArgumentNullException is thrown by the update method when Property is null; when false, no exception is thrown and the binding update silently fails.
ThrowWhenPropertyIsMissing	bool	true	When true, an ArgumentNullException is thrown by the update method when Property doesn't exist on the attached object; when false, no exception is thrown and the binding update silently fails.

IntervalCallback

Properties

Property	Default	Description
EnableTimer	true	When true, the timer is enabled & TimerCallback is called every time the Interval has elapsed; When false, the timer is disabled & TimerCallback is not called.
Interval		The timer interval, in milliseconds. (type double)
TimerCallback		A callback delegate of type System.Timers.ElapsedEventHandler that will be invoked every time the timer is triggered.

BaseIntervalBehavior

If you want to create your own timer class, you can inherit from the abstract base class with your own implementation.
See the source code for implementation details & examples.
