The FilterChange event notifies your application that the user filters files/folders in the control. Use the ColumnFilterButton property to display a filter button in the column's caption. Use the AddColumnCustomFilter method to add custom filter patterns to the column. Use the ColumnFilter, ColumnFilterType properties and ApplyFilter method to apply a filter to the control's content. Use the Get property to retrieve all, selected or checked items. Use the Folder property to specify whether the File object holds a file or a folder.

The following VB sample displays the list of files once that user changes the filter:

Private Sub ExFileView1_FilterChange()
    With ExFileView1.Get(VisibleItems)
        For i = 0 To .Count - 1
            With .Item(i)
                Debug.Print .Name
            End With
        Next
    End With
End Sub

The following C++ sample displays the list of files once that user changes the filter:

void OnFilterChangeExfileview1() 
{
	CFiles files = m_fileview.GetGet( 3 /*VisibleItems*/ );
	for ( long i = 0; i < files.GetCount(); i++ )
		OutputDebugString( files.GetItem( COleVariant( i ) ).GetName() );
}

The following VB.NET sample displays the list of files once that user changes the filter:

Private Sub AxExFileView1_FilterChange(ByVal sender As Object, ByVal e As System.EventArgs) Handles AxExFileView1.FilterChange
    With AxExFileView1.get_Get(EXFILEVIEWLib.TypeEnum.VisibleItems)
        Dim i As Integer
        For i = 0 To .Count - 1
            With .Item(i)
                Debug.WriteLine(.Name())
            End With
        Next
    End With
End Sub

The following C# sample displays the list of files once that user changes the filter:

private void axExFileView1_FilterChange(object sender, EventArgs e)
{
	EXFILEVIEWLib.Files files = axExFileView1.get_Get(EXFILEVIEWLib.TypeEnum.VisibleItems);
	for (int i = 0; i < files.Count; i++)
	{
		EXFILEVIEWLib.File file = files[i];
		System.Diagnostics.Debug.WriteLine(file.Name);
	}
}

The following VFP sample displays the list of files once that user changes the filter:

*** ActiveX Control Event ***

With thisform.ExFileView1.Get(3)	&& VisibleItems
	For i = 0 To .Count - 1
		With .Item(i)
			wait window nowait .Name
		EndWith
	Next
EndWith
