Examples

The code below shows an implementation of a multiItem that list all of the feature layers in the current map. Clicking on each item makes the map zoom to the corresponding layer.

public class ZoomToLayerMultiItem : ESRI.ArcGIS.Desktop.AddIns.MultiItem

  protected override void OnClick(Item item)
  {
    int index = this.IndexOf(item);
    System.Diagnostics.Debug.WriteLine("The index of the clicked item is " + index.ToString());
    ESRI.ArcGIS.Carto.IMap map = ArcMap.Document.FocusMap;
    ESRI.ArcGIS.Carto.ILayer layer = item.Tag as ESRI.ArcGIS.Carto.ILayer;
    ESRI.ArcGIS.Geometry.IEnvelope env = layer.AreaOfInterest;
    ArcMap.Document.ActiveView.Extent = env;
    ArcMap.Document.ActiveView.Refresh();
