Infragistics.Win.UltraWinGrid Namespace : RowEventHandler Delegate

sender
e
delegate for handling events that take a RowEventArgs as the event args

Syntax

Visual Basic (Declaration) 
Public Delegate Sub RowEventHandler( _
   ByVal sender As Object, _
   ByVal e As RowEventArgs _
) 
C# 
public delegate void RowEventHandler( 
   object sender,
   RowEventArgs e
)

Parameters

sender
e

Example

Following code shows some of the information available in AfterRowUpdate event. It gets the underlying DataRow associated with the row that was updated and prints out its RowState property. For this to work, the UltraGrid must be bound to a DataSet.

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.
