MapPushpin Class

The class used to draw a pushpin on a map.

Namespace: DevExpress.Xpf.Map

Assembly: DevExpress.Xpf.Map.v22.2.dll

NuGet Package: DevExpress.Wpf.Map

Declaration

C#

public class MapPushpin :
    MapItem,
    IWeakEventListener,
    ISupportCoordLocation,
    IPointCore,
    IClusterable,
    IClusterItemCore,
    IClusterItem

VB.NET

Public Class MapPushpin
    Inherits MapItem
    Implements IWeakEventListener,
               ISupportCoordLocation,
               IPointCore,

Remarks

A pushpin is a pointer that marks a geographical point on a map.

A typical map pushpin is shown in the image below.

An instance of a map pushpin is represented by the MapPushpin object that is descendant of a VectorLayer object.

Use the MapPushpin.Location property to specify the pushpin position on a map.

In addition, you can change the pushpin state (MapPushpin.State), specify its text (MapPushpin.Text) and other appearance settings (MapPushpin.TraceDepth, MapPushpin.TraceStroke).

To learn more on pushpins, see the Vector Items topic.

Example

This example illustrates how to provide animation for a map pushpin.

To do this, it is necessary to create a PushpinLocationAnimation object and assign it to the MapPushpin.LocationChangedAnimation property. After that, it becomes possible to customize the animation duration (PushpinLocationAnimation.Duration) and easing function (PushpinLocationAnimation.EasingFunction).

In addition, you can change the pushpin state after its location animation is complete via the PushpinLocationAnimation.Completed event. In this example, this event is used to change the pushpin location randomly each time the bouncing animation effect is complete.
