Field Value

The active map display.

This static property allows you to get a reference to the MapDisplay from within the code of your add-in, as shown in the example code.

Note that you may have to fully-qualify the Application class if you have a reference to System.Windows.Forms as it may clash with the Application class in that namespace.

The code below shows how you can get a reference to the current MapDisplay and Map within add-in code, by using the static ActiveMapDisplay member of the Application class. The path and name of the current map is then reported. This code assumes you have a using/imports statement for the ESRI.ArcGISExplorer.Mapping namespace. It also assumes that you may have a using/imports statement for the System.Windows.Forms namespace, and therefore the Application class is fully qualified in order to avoid conflicts.

CopyC#

MapDisplay currentDisplay = ESRI.ArcGISExplorer.Application.Application.ActiveMapDisplay;
Map currentMap = currentDisplay.Map;
System.Diagnostics.Debug.WriteLine("The map at " + currentDisplay.MapPath + " is called " + currentMap.Name);

CopyVB.NET

Dim currentDisplay As MapDisplay = ESRI.ArcGISExplorer.Application.Application.ActiveMapDisplay
Dim currentMap As Map = currentDisplay.Map
System.Diagnostics.Debug.WriteLine("The map at " & currentDisplay.MapPath & " is called " & currentMap.Name)
