Editor Property (ItemExitingEditModeEventArgs)

Returns the EmbeddableEditorBase-derived editor that is conducting the edit mode session.
Syntax
'Declaration
 
Public ReadOnly Property Editor As Infragistics.Win.EmbeddableEditorBase
public Infragistics.Win.EmbeddableEditorBase Editor {get;}
Example
The following code sample demonstrates how to handle the UltraListView control's edit mode events to conditionally prevent an edit mode session from beginning or ending, as well as perform a specific action after edit mode is entered or exited:

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
