BeginStoryboard.Name Property

Gets or sets the name of the BeginStoryboard object. By naming the BeginStoryboard object, the Storyboard can be controlled after it is started.

Namespace:  System.Windows.Media.Animation
Assembly:  PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

public string Name { get; set; }
<object Name="string" .../>

Property Value

Type: System.String
The name of the BeginStoryboard. The default is null.

To be able to pause, resume, or otherwise interactively control a Storyboard, set the Name property of its BeginStoryboard and use a ControllableStoryboardAction object like PauseStoryboard, ResumeStoryboard, or StopStoryboard to reference this name. If the Name of BeginStoryboard is unspecified, the Storyboard cannot be interactively affected after it is begun; furthermore, when the Storyboard ends or enters its Fill period, the animation clocks are disposed of. See How to: Use Event Triggers to Control a Storyboard After It Starts for more information.

This example shows how to control a Storyboard after it starts. To start a Storyboard by using XAML, use BeginStoryboard, which distributes the animations to the objects and properties they animate and then starts the storyboard. If you give BeginStoryboard a name by specifying its Name property, you make it a controllable storyboard. You can then interactively control the storyboard after it starts.

Use the following storyboard actions together with EventTrigger objects to control a storyboard.

The following example uses controllable storyboard actions to interactively control a storyboard.

Note: To see an example of controlling a storyboard by using code, see How to: Control a Storyboard After It Starts.
