AutoResetOptions Property

public virtual ImageViewerAutoResetOptions AutoResetOptions {get; set;}

'Declaration
 

Public Overridable Property AutoResetOptions As ImageViewerAutoResetOptions

Property Value

Use this property to control which of the display properties of the controls resets back to its default value when a new image is set into the ImageUrl, Image or SvgDocument properties or when the user changes ImageSize directly.

The viewer will call Reset to perfrom the reseting of the values.

Run the demo and click the Example button. The image will be zoomed (its scale factor and scroll offset will be changed) to a certain value. Then the viewer will use AutoResetOptions to not change these values when a new image is set.

Start with the ImageViewer example, remove all the code inside the example function (search for the "// TODO: add example code here" comment) and insert the following code:

• C#
• Visual Basic
• WinRT C#
• WinRT JavaScript
• Silverlight C#
• Silverlight VB
