BeforeRowDeactivate Event

Occurs before a row is deactivated.
Syntax
'Declaration
 
Public Event BeforeRowDeactivate As CancelEventHandler
public event CancelEventHandler BeforeRowDeactivate
Event Data

The event handler receives an argument of type CancelEventArgs containing data related to this event. The following CancelEventArgs properties provide information specific to this event.

PropertyDescription
Cancel  
Remarks

Thecancelargument enables you to programmatically prevent the the row from deactivating, meaning it does not lose focus. This argument can be used to prevent the user from leaving the row unless a certain condition is met.

This event is generated when the user attempts to move to a different row, deactivating the original row.

TheBeforeRowActivateevent is generated before a row is activated, which means it will get focus.

TheActiveRowproperty can be used to determine which row is currently active.

Example
The following sample code illustrates how one can use combination of BeforeRowDeactivate and BeforeRowActivate to change the ActiveRow's appearance. ActiveRowAppearance 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.
