radgridview SaveLayout

[Tasos]

Hi
when i am trying to save the layout of a radGridView to a memory stream i get the following error:
Property accessor 'EnableFastScrolling' on object 'Telerik.WinControls.UI.RadGridView' threw the following exception:'Object reference not set to an instance of an object.'
i am using devstudio 2012, win8.1, .net framework 4.0

Can you help please?

Hello Tasos,

Thank you for writing.

Following the provided information, I tried to reproduce the mentioned exception in the specified version 2014.2 715, but without any success. Here is my sample code snippet:

Private ms As New MemoryStream()

Public Sub New()
    InitializeComponent()
    Dim r As New Random()
    Dim table As New DataTable()
    table.Columns.Add("ID", GetType(Integer))
    table.Columns.Add("Name", GetType(String))
    table.Columns.Add("Bool", GetType(Boolean))
    table.Columns.Add("DateColumn", GetType(DateTime))
    For i As Integer = 0 To 9
        table.Rows.Add(i, "Row " & i, If(r.[Next](10) > 5, True, False), DateTime.Now.AddHours(i))
    Next
    Me.RadGridView1.DataSource = table
    RadGridView1.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill
    RadGridView1.EnableFastScrolling = True
End Sub

Private Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click
    RadGridView1.SaveLayout(ms)
End Sub

Private Sub RadButton2_Click(sender As Object, e As EventArgs) Handles RadButton2.Click
    RadGridView1.LoadLayout(ms)
End Sub

Could you please specify the exact steps how to reproduce the problem? It would be greatly appreciated if you provide a sample project in the support thread that you have opened on a similar topic so I can investigate the precise case. Thank you in advance.
