Why FocusedrowChanged GridView in DevExpress runs slowly in vb.net

Why FocusrowChanged GridView in DevExpress runs slowly in vb.net?

Is there a solution so it doesn't get slow? And the image data there are four thousand. If I run FocusedRowChanged in gridview in the image in pictureedit it immediately appears but the row shift is not direct and becomes slow.

Thanks

Private Sub GridView1_FocusedRowChanged(sender As Object, e As FocusedRowChangedEventArgs) Handles GridView1.FocusedRowChanged
        Dim view As GridView = TryCast(sender, GridView)

        If view.FocusedRowHandle = GridControl.AutoFilterRowHandle Then
            Return
        End If

        Dim SUBFOLDERP As String = view.GetFocusedRowCellValue("SUBFOLDERP")?.ToString
        Dim Filename1 As String = view.GetFocusedRowCellValue("FILENAME1")?.ToString
        Dim Filename2 As String = view.GetFocusedRowCellValue("FILENAME2")?.ToString
        parentpathimage = Directory.GetCurrentDirectory()
        Dim filePath1 = DevExpress.Utils.FilesHelper.FindingFileName(parentpathimage & "\" & SUBFOLDERP & "\", Filename1, False)
        Dim filePath2 = DevExpress.Utils.FilesHelper.FindingFileName(parentpathimage & "\" & SUBFOLDERP & "\", Filename2, False)
        If Not String.IsNullOrWhiteSpace(filePath1) Then
            PictureEdit1.Image = Image.FromStream(New MemoryStream(File.ReadAllBytes(filePath1)), True, False)
            If Not String.IsNullOrWhiteSpace(filePath2) Then
                PictureEdit2.Image = Image.FromStream(New MemoryStream(File.ReadAllBytes(filePath2)), True, False)
            End If
        End If
    End Sub
