BeforeRowActivate Event

Occurs before a row is activated.
Syntax
public event RowEventHandler BeforeRowActivate
Event Data

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

PropertyDescription
Row The row (usually the row that the cell belongs to) (read-only)
Remarks

The row argument returns a reference to an UltraGridRow object that can be used to set properties of, and invoke methods on, the row that will be activated. You can use this reference to access any of the returned row's properties or methods.

This event is generated before a row is activated, which means it has been given focus.

The BeforeRowDeactivate event is generated before a row is deactivated, meaning it will lose focus.

The AfterRowActivate event, which occurs after a row is activated, is generated after this event.

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.
