Class Callout

A callout control used for rendering a Callout on top of the GeoView

Inheritance

System.Object

Callout

Implements

IViewOverlay

Namespace: Esri.ArcGISRuntime.UI.Controls

Assembly: Esri.ArcGISRuntime.WinUI.dll

Syntax

public class Callout : ContentControl, IViewOverlay

Remarks

The Callout control is used by the GeoView when displaying a single callout using the ShowCallout* methods. However the callout can also be used as a control inside the Overlays collection. This control implements the IViewOverlay interface, that allows it to adapt to the placement on screen and re-flow the location of the leader arrow that points to the location.

Methods

Name	Description
OnApplyTemplate()	Invoked whenever application code or internal processes (such as a rebuilding layout pass) call . In simplest terms, this means the method is called just before a UI element displays in your app. Override this method to influence the default post-template logic of a class.
OnArrangeOverlay(ViewOverlayArrangeParameters)	Called when the callout is about to be repositioned on the view

Name	Description
IViewOverlay.ArrangeOverlay(ViewOverlayArrangeParameters)	Provides the behavior for the ArrangeOverlay pass of layout. Controls can implement this method to define their own ArrangeOverlay pass behavior for when they are part of the Overlays collection.
