Infragistics.Win.UltraWinGrid Namespace : CancelableCellEventArgs Class

Event parameters used for events that take a row and a column designating a cell (the cell at the intersection of the row and the column) as their argument and are cancelable

Syntax

Visual Basic (Declaration) 
Public Class CancelableCellEventArgs 
   Inherits System.ComponentModel.CancelEventArgs
C# 
public class CancelableCellEventArgs : System.ComponentModel.CancelEventArgs 

Example

The following sample code illustrates how one can use combination of BeforeCellActivate and BeforeCellDeactivate to change the ActiveCell's appearance. ActiveCellAppearance property off the UltraGridOverride can be used to accomplish the same thing.

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.
