OnValueChanged Method (UltraProgressBar)

Raises the ValueChanged event when the Value property changes.

Syntax

Visual Basic

'Declaration
 
Protected Overridable Sub OnValueChanged( _
   ByVal e As EventArgs _
) 

C#

protected virtual void OnValueChanged( 
   EventArgs e
)

Parameters

e

An System.EventArgs that provides data for the event.

Remarks

Raising an event invokes the event handler through a delegate.

The OnValueChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors: When overriding OnValueChanged in a derived class, be sure to call the base class's OnValueChanged method so that registered delegates receive the event.

Example

The following sample code illustrates what information is available in the ValueChanged event.

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.

Visual Basic

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinProgressBar
Imports System.Diagnostics

   Private Sub ultraProgressBar1_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ultraProgressBar1.ValueChanged

       Dim pbar As UltraProgressBar

       pbar = sender

       Debug.WriteLine("Progress bar: " + pbar.Name)
       Debug.WriteLine("new value: " + pbar.Value.ToString())

   End Sub

C#

using System.Diagnostics;
using Infragistics.Win;
using Infragistics.Win.UltraWinProgressBar;

private void ultraProgressBar1_ValueChanged(object sender, System.EventArgs e)
{

	UltraProgressBar pbar = sender as UltraProgressBar;

	Debug.WriteLine( "Progress bar: " + pbar.Name );
	Debug.WriteLine( "new value: " + pbar.Value.ToString() );
