Issue working with RadForm in MDI mode

Hi,

I'm working with RadForm in MDI Mode. I Just added a main form with IsMdiContainer = True and I added some children RadForm setting the properties MdiParent. I'm using Telerik WinForm Q2 2011.

ISSUE: When I maximize one Child RadForm, the "Maximize" icon in the top-right corner of the form doesn't change. Instead of the "Restore Down" icon, the RadForms shows always the "Maximize" icon. See the attached picture for a screenshot of this problem.

Thanks in advance,
Lorenzo

I have a problem using datatable.getChanges method with a radGridView binded on a datatable, changing values programmaticaly:
The first changed value is not in the datatable.getChanges results.

Here is a simple example :

Designer.vb

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _

Partial Class testTelerik

Inherits System.Windows.Forms.Form

'Form remplace la méthode Dispose pour nettoyer la liste des composants.

<System.Diagnostics.DebuggerNonUserCode()> _

Protected Overrides Sub Dispose(ByVal disposing As Boolean)

Try

If disposing AndAlso components IsNot Nothing Then

components.Dispose()

End If

Finally

MyBase.Dispose(disposing)

End Try

End Sub

Dim dt As DataTable = DirectCast(RadGridView1.DataSource, DataTable)

RadGridView1.Rows(0).Cells(0).Value = "NewOne"

RadGridView1.Rows(1).Cells(0).Value = "NewOne2"

Dim changes As DataTable = dt.GetChanges

MessageBox.Show(changes.Rows.Count.ToString + " change(s)")

End Sub

End Class

I expect 2 changes whereas i have only 1..

Is this a bug ?
Is there a workaround?

Thanks,
Gerald

Can items rotate AROUND a center object?

I really like the look of the Carousel and I'm wondering if it's possible to put an image in the center (axis) around which the elements rotate.

So, when it rotates to the back, it would go behind the image and then come back out again on the other side.

My idea is to put a logo in the center. The items would never STOP behind the logo, but it would be a cool effect to have the items pass behind it. Really sells the 3D illusion.
