Overloads
| ChangeView(IReference<Double>, IReference<Double>, IReference<Single>) |
Causes the ScrollViewer to load a new view into the viewport using the specified offsets and zoom factor. |
| ChangeView(IReference<Double>, IReference<Double>, IReference<Single>, Boolean) |
Causes the ScrollViewer to load a new view into the viewport using the specified offsets and zoom factor, and optionally disables scrolling animation. |
Causes the ScrollViewer to load a new view into the viewport using the specified offsets and zoom factor.

public bool ChangeView(System.Nullable<double> horizontalOffset, System.Nullable<double> verticalOffset, System.Nullable<float> zoomFactor);function changeView(horizontalOffset, verticalOffset, zoomFactor)Public Function ChangeView (horizontalOffset As Nullable(Of Double), verticalOffset As Nullable(Of Double), zoomFactor As Nullable(Of Single)) As BooleanParameters
- horizontalOffset
-
IReference<double>
A value between 0 and ScrollableWidth that specifies the distance the content should be scrolled horizontally.
- verticalOffset
-
IReference<double>
A value between 0 and ScrollableHeight that specifies the distance the content should be scrolled vertically.
- zoomFactor
-
IReference<float>
A value between MinZoomFactor and MaxZoomFactor that specifies the required target ZoomFactor.
Returns
bool
true if the view is changed; otherwise, false.
- Attributes
Examples
This code results in a ScrollViewer named myScrollViewer being scrolled to a horizontal offset of 2.
bool flag = myScrollViewer.ChangeView(2, null, null);
bool flag{ myScrollViewer.ChangeView(Windows::Foundation::IReference<double>{2.f}, nullptr, nullptr) };
Remarks
You can set parameter values to null to use this method to scroll only horizontally, only vertically, or to only change the zoom factor.

- horizontalOffset
-
IReference<double>
A value between 0 and ScrollableWidth that specifies the distance the content should be scrolled horizontally.
- verticalOffset
-
IReference<double>
A value between 0 and ScrollableHeight that specifies the distance the content should be scrolled vertically.
- zoomFactor
-
IReference<float>
A value between MinZoomFactor and MaxZoomFactor that specifies the required target ZoomFactor.
- disableAnimation
-
Boolean
bool
true to disable zoom/pan animations while changing the view; otherwise, false. The default is false.
Returns
bool
true if the view is changed; otherwise, false.

Examples
This code results in a ScrollViewer named myScrollViewer being scrolled to a horizontal offset of 2 without animation.
bool flag = myScrollViewer.ChangeView(2, null, null, true);
bool flag{ myScrollViewer.ChangeView(Windows::Foundation::IReference<double>{2.f}, nullptr, nullptr, true) };
Remarks
You can set parameter values to null to use this method to scroll only horizontally, only vertically, or to only change the zoom factor.
