FilterChanging question

[Jason Parrish]

The GridViewCollectionChangingEventArgs on the FilterChanging event does not appear to be updated correctly.  After the first filter change event, subsequent filters do not update NewItems and OldItems correctly.

The NewItems(0) does not reflect the updated filtered text.  However, the NewValue does show the updated text.   The OldItems(0) always equals zero, but OldValue is correct.

In addition, if the filter operator changes, the same discrepancy occurs, however the NewValue and OldValue are changed to an number.  I'm assuming it is the enumerator of the operator.

See the screenshot and code example.  I've opened a support ticket in case it is an actual bug, but hoping it is not and I'm just using it incorrectly.

Imports System.ComponentModel

Public Class Form1

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        Dim foo As New BindingList(Of Person)

        Dim i As Integer
        Do Until i = 100
            foo.Add(New Person("Name " & i.ToString))
            i = i + 1
        Loop

        RadGridView1.DataSource = foo
    End Sub


    Public Class Person
        Property Name As String

        Public Sub New(ByVal Name As String)
            _Name = Name
        End Sub
    End Class


    Private Sub RadGridView1_FilterChanging(sender As Object, e As Telerik.WinControls.UI.GridViewCollectionChangingEventArgs) Handles RadGridView1.FilterChanging
        TextBox1.Text = e.NewItems(0).ToString
        TextBox2.Text = e.NewValue

        If e.OldItems IsNot Nothing Then
            TextBox3.Text = e.OldItems(0).ToString
            TextBox4.Text = e.OldValue
        End If
    End Sub
End Class
