IEditor.Location Property (ArcObjects .NET 10.4 SDK)

ArcObjects Library Reference (Editor)

IEditor.Location Property

[Visual Basic .NET]
Public ReadOnly Property Location As IPoint

[C#]
public IPoint Location {get;}

Available with ArcGIS Desktop.

This property is set when you right-click on the edit sketch. Once a point has been stored in this property, it remains there until the next time you right-click on the edit sketch.

Use this property when creating custom commands in the sketch context menu that require a point location to perform some operation. For example, the 'Insert Vertex' command use the location property to determine where to add the new vertex.

If you need the location of the sketch tool for a command in the sketch tool context menu, use the ISketchTool::Location property.

[C#]

IEditor editor;
//get a reference to m_app(hook) in the ICommand::OnCreate method.
editor=m_app.FindExtensionByName("ESRI Object Editor")
 
IPoint point=new PointClass();
point=m_editor.Location;

System.Windows.Forms.MessageBox.Show(point.X.ToString("N2") + ", "
