PropertyGrid.PropertyValueChanged Event

Occurs when a property value changes.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

'Declaration
Public Event PropertyValueChanged As PropertyValueChangedEventHandler
'Usage
Dim instance As PropertyGrid
Dim handler As PropertyValueChangedEventHandler

AddHandler instance.PropertyValueChanged, handler

/** @event */
public void add_PropertyValueChanged (PropertyValueChangedEventHandler value)

/** @event */
public void remove_PropertyValueChanged (PropertyValueChangedEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

For more information about handling events, see Consuming Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the PropertyValueChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing System.Windows.Forms.MessageBox.Show with System.Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type PropertyGrid named PropertyGrid1. Then ensure that the event handler is associated with the PropertyValueChanged event.

Private Sub PropertyGrid1_PropertyValueChanged(sender as Object, e as PropertyValueChangedEventArgs) _ 
     Handles PropertyGrid1.PropertyValueChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ChangedItem", e.ChangedItem)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "OldValue", e.OldValue)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"PropertyValueChanged Event")

End Sub
