How can i create a simple application window?

Hello,
I use the Telerik WPF Controls as a trial with a Visual Studio 2012 Professional. So far it's me, unfortunately, not been able to create a simple application window.

I use the RadWindow control. But whenever I run the program, it will run in a separate window that displays below a deactivated navigationbar.

How can I display only the pure application window without this will be shown again in a window?

Infinite Loop/Hang in GridView when items completely fill grid without vertical scrollbar

We are using version 2009.1.526.35 of the GridView control. Because of our project timeline and for regression reasons, we are unable to upgrade to the newest version of RadGridView at this time. However, it is on our list of tasks once it becomes feasible. We are experiencing an issue where the RadGridView hangs and pegs the CPU at 50% forever in certain circumstances. We would like to know the following:

1) Is this issue fixed in the current version of the control.

2) Is there a workaround for the version of the control we have.

The issue is triggered when there are just enough items in the grid that the grid is full and the last item is even clipped slightly by the bottom of the grid. There are no vertical scrollbars yet. Our testers found the problem by opening a page with a grid that had enough items to produce a scrollbar. Then, when you maximize the screen and the result is a grid that is just full without scrollbars, the application hangs and the CPU is pegged at 50%. We isolated this to the grid by deleting one row from the database and observing the problem no longer occurs. It is the exact number of items in the grid causing the issue. Could you answer our 2 questions listed above? Thanks.

Drag & Drop not working after Upgrade

Greetings,

I have recently upgraded to the newest RAD Controls for WPF and discovered problem with Drag & Drop. It is not working after upgrade.
I have made small project to verify that problem is not in our code and when I use dlls of version "2012.3.1129.40" it is working without problem. When I use dlls of version 2013.2.0611.40 it is not working. Could you help me out?

In attachement I sent a small WPF project. You can see that in xaml I aneble dragging on each item in RadTreeView and in the code you can see that I add handlers for Drag & Drop operations. When drop occurs I add info about it to the listbox. For old dlls it works but for new ones it does not.

Xaml:

How can i define a ItemTemplate for RadRibbonBackstageItem?

Hi,

Her my code...

<telerik:RadRibbonWindow

x:Class="WpfRibbonBackstage.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.RibbonView"

Title="MainWindow" Height="350" Width="525">

<Grid>

<Grid.Resources>

<DataTemplate x:Key="BackstageSmallButtonTemplate">

<telerik:RadRibbonBackstageItem Header="{Binding Text}"

IsDefault="{Binding IsDefault}"

IsSelectable="{Binding IsSelectable}"

IsGroupSeparator="{Binding IsGroupSeparator}"

CloseOnClick="{Binding CloseOnClick}"/>

</DataTemplate>

</Grid.Resources>

<telerik:RadRibbonView x:Name="Ribbon"

Title="Test"

ApplicationButtonContent="FILE"

ApplicationButtonVisibility="Visible"

>

<telerik:RadRibbonTab Header="Home"></telerik:RadRibbonTab>

<telerik:RadRibbonView.Backstage>

<telerik:RadRibbonBackstage ItemsSource="{Binding BackstageItems}"

ItemTemplate="{StaticResource BackstageSmallButtonTemplate}"

SelectedItem="{Binding SelectedBackstageItem}">

</telerik:RadRibbonBackstage>

</telerik:RadRibbonView.Backstage>

</telerik:RadRibbonView>

</Grid>

</telerik:RadRibbonWindow>

The Header binding works, but all other not!
Waht is wrong?

Radchart 3d Pie Styling Issues

I've recently undertaken a project using an older version of RadControls and I'm really struggling in my attempt to customize the 3d pie chart. For reference, the developer machine has the Q1 2011 RadControls for WPF installed on it.

What I'm trying to do is style the item labels in some way that they don't overlap, or barring that, add some customized tooltips that display the label data. I've done a ton of research and playing around with custom styles, but:

A: 3d Pie labels/tooltips on this version appear to be Un-stylable or
B: I'm way off on attempts to restyle.

The latter seems unlikely since I was able to restyle the labels on a 2d pie chart using the same static resource, but I haven't found any documentation explicitly stating that the labels in this chart are not able to be styled.

Is there any older documentation available that could help me figure this out?

Also, I'm using MVVM format so code behind solutions are not very practical.
