Assembly: PresentationFramework (in PresentationFramework.dll)

A ProgressBar control consists of a window that is filled, by default from left to right, as an operation progresses. The control has a range and a current position.
ProgressBar overrides the metadata of the Maximum property and sets its default to 100. ProgressBar overrides the metadata of the Focusable property and sets its default to false. For more information, see Dependency Properties Overview.
Dependency properties for this control might be set by the control’s default style. If a property is set by a default style, the property might change from its default value when the control appears in the application. The default style is determined by which desktop theme is used when the application is running. For more information, see Themes.
This example creates a ProgressBar and uses an animation to simulate the progress of an operation.
