Is it still included?

The WPF Controls Examples contains examples for it but they will never load. All other examples do load.

Also it does not seem to exist in the library:
Error 1 The tag 'RadNumericUpDown' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation'.

Drag and Drop within ListBox with databound SelectedItem causes null set

Hello,

I am trying to get Drag and Drop to work within a single RadListBox. I have the ItemsSource and SelectedItem bound (TwoWay). Whenever I drop an item within the listbox, the SelectedItem setter gets called with a value of null. I was able to reproduce this by updating the SDK sample "CustomListBoxDragDropBehavior_WPF" with the following:

<telerik:RadListBox ItemContainerStyle="{StaticResource DraggableListBoxItem}"

ItemsSource="{Binding Customers1}"

SelectedItem="{Binding SelectedCustomer1, Mode=TwoWay}"

private Customer selectedCustomer1;

public Customer SelectedCustomer1

{

get { return selectedCustomer1; }

set

{

selectedCustomer1 = value;

this.OnPropertyChanged(() => this.SelectedCustomer1);

}

How do I prevent the selected item to be called with null?

Thanks,
Steve

Tile contents do not allow Binding

Hi,

I am creating a Silverlight project with the intent to be linked from WPF project as well. Here is the issue I am facing described in StackOverflow question

<telerik:Tile TileType="Single" Width="Auto" Background="#FF559B55" Name="tile1" 
                                      FontWeight="Bold" FontFamily="Verdana">


                                <Button Content = {Binding Path=MyRVal} Click="btClick" Foreground="Black">
                                   </Button>         

</telerik:Tile>

This works fine in Silverlight project, but the button does not show in WPF. I noticed this only happens when there is Binding instead of static, does WPF not handle this?
I know this might not be Telerik issue, but I wanted to ask and maybe get suggestions of how to have a Button or other control (with Binding) within a Tile working both in Silverlight and WPF.

Thanks
