    GroupAdded Event
    In This Topic

    The GroupAdded event is raised when a group has been added to the grid to allow manipulation of a new group once it has been created.  

    Basic steps - C#

    To subscribe to the GroupAdded event, the following steps must be performed:

    • Obtain a reference to a GridControl object. 

    • Subscribe to the GroupAdded event of the GridControl object using the GroupAddedEventHandler delegate class 

    • Create a new method that will handle the events that are raised. For the purposes of this example, we will call the method grid_GroupAdded. 

    • Place the desired code in the newly created event handler.

    Basic steps - VB.NET

    To subscribe to the GroupAdded event, the following steps must be performed:

    • Obtain a reference to a GridControl object . 

    • Subscribe to the GroupAdded event of the GridControl object using the AddHandler/AddressOf keywords. 

    • Create a new method that will handle the events that are raised. For the purposes of this example, we will call the method grid_GroupAdded. 

    • Place the desired code in the newly added event handler.

    Demonstration

    This example assumes that you are in a Windows application.

    VB.NET Copy Code

    Imports Xceed.Grid 
    AddHandler gridControl1.GroupAdded, AddressOf Me.grid_GroupAdded

    ' This method will handle the GroupAdded events that are raised.
    Private Sub grid_GroupAdded( ByVal sender As Object, _
                                 ByVal e As GroupAddedEventArgs)                               
        Try
           e.Group.FooterRows.Add( New TextRow( "This group contains " + _
                                                e.Group.GetSortedDataRowCount().ToString() + _
                                               " rows." ) )
       Catch exception As Exception
           MessageBox.Show( exception.ToString() )
       End Try
    End Sub

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

    C# Copy Code
    using Xceed.Grid; 
    gridControl1.GroupAdded += new GroupAddedEventHandler( grid_GroupAdded ); 
    // This method will handle the GroupAdded events that are raised.
    private void grid_GroupAdded( object sender, GroupAddedEventArgs e )
    {
       try
       {
           e.Group.FooterRows.Add( new TextRow( "This group contains " + _
                                                e.Group.GetSortedDataRowCount().ToString() + _
                                               " rows." ) );
       }
       catch( Exception exception )
       {
           MessageBox.Show( exception.ToString() );
       }
    }
    // If you no longer wish to handle the GroupAdded events that are raised,
    //you can unsubscribe from the event notification by doing the following: 
    gridControl1.GroupAdded -= new GroupAddedEventHandler( grid_GroupAdded );
