True if the row has already been initialized (read-only)

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property ReInitialize As Boolean

C#

public bool ReInitialize {get;}

Example

Following code shows some of the information available in InitializeGroupByRow event and its potential uses. It sets the appearance of the group-by rows based on number of items they contain.

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.
