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:
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!

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) |

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. |

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. |

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.
