Using the PropertyChanged events

Raised when the value of a grid element's property changes to provide notification that the property has been modified. These events can be used, for example, to update a text box with new information when something on the grid changes.

Basic steps - C#

To subscribe to a PropertyChanged event, for example the GridControl.CurrentRowChanged event, the following steps must be performed:

Obtain a reference to a GridControl object.
Subscribe to the CurrentRowChanged event of the GridControl object using the default delegate class.
Create a new method that will handle the events that are raised.
Place the desired code in the newly created event handler.

Basic steps - VB.NET

To subscribe to a PropertyChanged event, for example the GridControl.CurrentRowChanged event, the following steps must be performed:

Obtain a reference to a GridControl object.
Subscribe to the CurrentRowChanged event of the GridControl object using the AddHandler/AddressOf keywords.
Create a new method that will handle the events that are raised.
Place the desired code in the newly created event handler.

Demonstration

This example assumes that you are in a Windows application.

VB.NET Copy Code

VB.NET	Copy Code
`Imports Xceed.Grid` `Dim grid As New GridControl() AddHandler grid.CurrentRowChanged, AddressOf Me.grid_CurrentRowChanged` `Private Sub grid_CurrentRowChanged( ByVal sender As Object, ByVal e As EventArgs ) ' Add code here End Sub` `' If you no longer wish to handle the CurrentRowChanged events that are raised, ' you can unsubscribe from the event notification by doing the following: RemoveHandler grid.CurrentRowChanged, AddressOf Me.grid_CurrentRowChanged`

Imports Xceed.Grid

Dim grid As New GridControl() AddHandler grid.CurrentRowChanged, AddressOf Me.grid_CurrentRowChanged

Private Sub grid_CurrentRowChanged( ByVal sender As Object, ByVal e As EventArgs ) ' Add code here End Sub

' If you no longer wish to handle the CurrentRowChanged events that are raised, ' you can unsubscribe from the event notification by doing the following: RemoveHandler grid.CurrentRowChanged, AddressOf Me.grid_CurrentRowChanged

C# Copy Code

C#	Copy Code
`using Xceed.Grid; GridControl grid = new GridControl(); grid.CurrentRowChanged += new EventHandler( this.grid_CurrentRowChanged );` `// This method will handle the CurrentRowChanged events that are raised. private void grid_CurrentRowChanged( object sender, EventArgs e ) { // Add code here }` `// If you no longer wish to handle the CurrentRowChanged events that are raised, // you can unsubscribe from the event notification by doing the following: grid.CurrentRowChanged -= new EventHandler( this.grid_CurrentRowChanged );`

using Xceed.Grid; GridControl grid = new GridControl(); grid.CurrentRowChanged += new EventHandler( this.grid_CurrentRowChanged );

// This method will handle the CurrentRowChanged events that are raised. private void grid_CurrentRowChanged( object sender, EventArgs e ) { // Add code here }

// If you no longer wish to handle the CurrentRowChanged events that are raised, // you can unsubscribe from the event notification by doing the following: grid.CurrentRowChanged -= new EventHandler( this.grid_CurrentRowChanged );

Remarks

The PropertyChanged events are not raised when the value of a parent's property changes.
