In the release notes for Q3 2012 (version 2012.3.1017), for ListBox I see:
"Implemented AutoScrolling in ListBox. Added SmoothScrolling virtualized panel. "

How can I turn on smoothscrolling and autoscrolling?

I set the theme explicitly from a copy of your theme file:

<ResourceDictionary.MergedDictionaries>
  <ResourceDictionary Source="../Themes/Telerik.Windows.Controls.Navigation.xaml"/>
</ResourceDictionary.MergedDictionaries>

I have this menu item:
<telerik:RadMenuItem x:Name="mainMenuFileExit" Header="E_xit" Command="{StaticResource Commands.ExitApplication}"  />

When I set the theme to Windows 7 it works as expected:
Telerik\RadControls for WPF Q3 2012\Themes.Implicit\WPF40\Windows7\Themes\Telerik.Windows.Controls.Navigation.xaml

However, if I choose another theme the access key is interpreted as part of the header text:
Telerik\RadControls for WPF Q3 2012\Themes.Implicit\WPF40\ExpressionDark\Themes\Telerik.Windows.Controls.Navigation.xaml

Clearly, something is wrong with your non-Windows7 themes.

I wish for my edit window (RentalTicket) to only open when I double click on a valid row.  I want nothing to happen if the headers are double clicked, or if the scrollbar is double clicked.
Also, when I click on blank space in my RadGridView, the selected row is still selected.  I think that the selected row should de-select if I click on a non row in the RadView Grid.

My RadGridView:

and this is my doubleClicked function:

Hi,

What would be the recommended approach for printing and print previewing the grid control ?
 Thanks,

I'm using CategoricalAxis to create a nice histogram plot. How can I hide the ticks on the horizontal axis?
I read about a MajorTicksVisibility property, but IntelliSense never shows it so I suspect it's not there...

<chart:RadCartesianChart x:Name="RadCartesianChart" Palette="Arctic" Margin="10">
        <chart:RadCartesianChart.DataContext>
            <viewModels:HistogramViewModel />
        </chart:RadCartesianChart.DataContext>
        <chartView:BarSeries ItemsSource="{Binding Data}" ValueBinding="Value"
                            ShowLabels="False" FontFamily="Segoe UI" FontSize="10">
        </chartView:BarSeries>
        <chart:RadCartesianChart.HorizontalAxis>
            <chartView:CategoricalAxis  GapLength="0" ShowLabels="False" FontFamily="Segoe UI" FontSize="12" />
        </chart:RadCartesianChart.HorizontalAxis>
        <chart:RadCartesianChart.VerticalAxis>
            <chartView:LinearAxis FontFamily="Segoe UI" FontSize="12"
                            Title="Histogram"
                            Minimum="0" Maximum="{Binding AxisMaxValue}"
                            ShowLabels="True" />
        </chart:RadCartesianChart.VerticalAxis>
        <chart:RadCartesianChart.Grid>
            <chartView:CartesianChartGrid MajorLinesVisibility="Y" />
        </chart:RadCartesianChart.Grid>
    </chart:RadCartesianChart>

With a recent update to Q3 2012, all of our RadListBox started to show the content with FontWeight="Bold", which was not the case with previous versions. As a result, many of our screens became plain ugly.

Was it a deliberate decision to make this theme change or is it a bug?

Even more, if the data template of a RadListBoxItem has a TextBlock with FontWeight set explicitly, it is ignored and the Bold style is used. 

Code example:

For this template, items are still shown with Bold.

I've checked and this behavior is specific for Windows8 & Metro themes, Windows7 still displaying items correctly.

Any workarounds to get our screens back to normal and looking good?

Thanks

Sorry, I miss typed the title.

We have an ExternalDLL directory where we store all external dll's that are used by our software product.
All Telerik dll's we use are in that directory too. The ExternalDLL is versioned in TFS. This worked great up to the 2012 Q3 release. 
If I do a get Latest version Visual Studio hangs on the Telerik.Windows.Documents.dll, if I wait a very long time Visual Studio reports the file is in use.

If I start Visual Studio without loading a project an just go to Team Explorer and get the Telerik.Windows.Documents.dll Visual Studio hangs again. I disabled my virus scanner but get the same result. Removing and adding the directory from my Workspace also hangs. Getting and loading the solution file also hangs VS 2010.

I'm using Visual Studio 2010, SP1 with the Silverlight 5 update on Windows 7 64 bit professional. Telerik is version 2012.3.1203.40.
I tried reproducing the problem on a 32 bit virtual machine, there I can get the Telerik.Windows.Documents.dll without a problem. Unfortunately the DirectShow video streams we are showing do not work in the Virutal Machine.

At this moment I can not do a Get Latest Version in Visual Studio so I'm stuck.

After some more testing we found that Telerik.Windows.Documents.dll version 2011.3.1220.40 can be get from TFS on a 64 bit Windows 7, but version 2012.3.1017.40 and 2012.3.1203.40 cannot be get on 64 bit from TFS, if I try that VS 2010 hangs. If you wait long enoug after an hour or so VS 2010 reports that the file dll is in use.

Does anybody have a clue how to solve this?

If I use your RadTabControl, I get error 26 in the Output window. Why?

System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='RadTabItem'

<telerik:RadTabControl x:Name="tabControl" Grid.Row="1" VerticalAlignment="Top"
                               DisplayMemberPath="Content" DropDownDisplayMode="Visible" ScrollMode="Viewport">
   <telerik:RadTabItem />
</telerik:RadTabControl>

I copied the Windows 7 theme from \RadControls for WPF Q3 2012\Themes.Implicit\WPF40\Windows7\Themes:

<Window.Resources>
   <ResourceDictionary>
      <ResourceDictionary.MergedDictionaries>
         <ResourceDictionary Source="../Themes/Telerik.Windows.Controls.Navigation.xaml"/>

The animation for opening and closing a panel that is using autohide is very jerky, and it seems the panel underneath flickers. This is visible even on the demo. Is there a fix for this?
