PanTo(IEnumerable<Layer>,Boolean,Nullable<TimeSpan>) Method

In This Topic

Pan the view to the extent of one or more layers. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public bool PanTo( 
   IEnumerable<Layer> layers,
   bool selectedOnly,
   Nullable<TimeSpan> duration
)

Public Overloads Function PanTo( _
   ByVal layers As IEnumerable(Of Layer), _
   Optional ByVal selectedOnly As Boolean, _
   Optional ByVal duration As Nullable(Of TimeSpan) _
) As Boolean

Parameters

layers: An enumeration of layers containing the features in which to pan.
selectedOnly: Indicates whether only the selected features for a layer should be used to determine the extent in which to pan.
duration: The amount of time to navigate the view to the new camera position. If null it uses the default navigation duration.

Return Value

True if the navigation is completed, false if it was interrupted by another view navigation.

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.

Remarks

Pan in 2D maintains the current camera scale and heading and modifies the X and Y position. Pan in 3D maintains the current camera pitch and heading and modifies the X and Y position.

Example

Pan To Visible Layers Synchronous

public Task<bool> PanToAllVisibleLayersAsync()
{
  return QueuedTask.Run(() =>
  {
    //Get the active map view.
    var mapView = MapView.Active;
    if (mapView == null)
      return false;

    //Pan to all visible layers in the map.
    var visibleLayers = mapView.Map.Layers.Where(l => l.IsVisible);
    return mapView.PanTo(visibleLayers);
  });
}

Pan To Visible Layers

public Task<bool> PanToAllVisibleLayersAsync()
{
  return QueuedTask.Run(() =>
  {
    //Get the active map view.
    var mapView = MapView.Active;
    if (mapView == null)
      return false;

    //Pan to all visible layers in the map.
    var visibleLayers = mapView.Map.Layers.Where(l => l.IsVisible);
    return mapView.PanTo(visibleLayers);
  });
}
