FrameworkElement.BringIntoView Method (Rect)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Attempts to bring the provided region size of this element into view, within any scrollable regions it is contained within.

Namespace:   System.Windows
Assembly:  PresentationFramework (in PresentationFramework.dll)

public void BringIntoView(
	Rect targetRectangle


Type: System.Windows.Rect

Specified size of the element that should also be brought into view.

By calling this method, you raise a RequestBringIntoView event that originates from the current element. This event is raised so that it can be handled by a ScrollViewer, or a derived or similar class. The expected behavior is that the event is handled by the parent element, marked handled in the event data, and the source of the event is brought into view through the logic embedded in the ScrollViewer control. Neither the RequestBringIntoView event nor the BringIntoView method transmit any information about success or failure, other than that the event is typically marked handled on success. Reasons for failure can include the element settings, such as Visibility being some value other than Visible.

If you use the signature that does not specify a targetRectangle, then the entire element size (its RenderSize) will be made visible.

By calling this method, you potentially will call MakeVisible on any parent scrollable area that contains the element. If this element is not contained in a scrollable area, the RequestBringIntoView event is still raised, but there will be no effect because there are no event listeners.

The following example has a large graphic in a constrained scrolling region. A button on the page has a handler that scrolls the view to a particular region of the large graphic.

<ScrollViewer Width="300" Height="300" HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible">
  <Image Name="mapframe" ScrollViewer.CanContentScroll="True"  >
      <BitmapImage UriSource="treasuremap.bmp"/>
  <Button Click="GoToLake">Go to Lake</Button>

void GoToLake(object sender, RoutedEventArgs e)
    mapframe.BringIntoView(new Rect(800, 400, 200, 200));
