Nested styles with RadToolBar

I was trying to apply a nested style on a RadToolbar and on its children. I had problems applying the style to certain children like RadButtons and RadToggleButtons. The same occurs with normal WPF Toolbars:

http://stackoverflow.com/questions/20219595/wpf-why-are-nested-styles-not-always-working/20220084?noredirect=1#20220084

The solution is, that you have to override the special style, that the Toolbar defines for Buttons, ToggleButtons etc. For this you need the Toolbar's ToggleButtonStyle Resourcekey which is provided by a normal WPF Toolbar via

public static ResourceKey ToggleButtonStyleKey { get; }

Where do I find this resource Key on a RadToolBar and how do I apply a nested style on all RadButtons/RadToggleButtons of a RadToobar?

Notification when print is cancelled

There exists an event on the editor called PrintCompleted, that I can use to know when my print operation has completed. I need this notification so my viewmodel can navigate away from the document that was edited. So far so good. The problem lies when the user hits the print dialog's "cancel" button. I need to be able to know if that happens because there are still things I need to do. Since there is no "PrintCancelled" event, how will I ever know the user cancelled that operation from the system print dialog? Is there even a way?

Thanks in advance!

Can not binding Property when using CellTemplateSelector

Hello,

i use RadGridView and want to set a GridViewDataColumn using CellTemplateSelector. I have used the DataMemberBinding to bind the property, but my selector gets only the whole item data.
ex. i have ViewModel MyVM and some properties. One of them named Status. And the xaml code like below.

<telerik:GridViewDataColumn Width="40" ColumnGroupName="status" Header="Header"
DataMemberBinding="{Binding Status}" SortMemberPath=

"Status"

CellTemplateSelector="{StaticResource myDataTemplateSelector}"/>

The item in myDataTemplateSelector ist always MyVM instead of MyVM.Status.
Any idea? Thanks!

Customise RadDiagramTextShape Text Alignment

RadDiagramTextShape seems to only centre its text content. Is it possible to change the alignment to include either: left, right or stretch?
The control doesn't seem to respond to the HorizontalContentAlignment or even the HorizontalAlignment property.

Can anyone help me please?

fast update of one RadGridView row

Hi,

I have a RadGridView bound to a large DataTable. Changing data in one row of that DataTable does not trigger a refresh of the RadGridView - the DataTable changes are not reflected in the UI. I have tried the following:

RadGridView.ItemsSource = null;

RadGridView.ItemsSource = GridDataTable;

or:

RadGridView.Items.Refresh();

or:

RadGridView.Rebind();

Each takes a very long time, presumably because the entire DataTable is being reloaded into the grid view. Is there any way to refresh only the DataRow that has changed?
