Are they any XAML parsers available? We have a requirement to parse the XAML files and extract the required information. Microsoft provides XAML Toolkit(http://archive.msdn.microsoft.com/XAML/), but it's in CTP and for som reason archived. Not sure what the roadmap is. Any inputs in this regard will be very helpful

How to make a line chart in wpf
Hi All,
I am working on a WPF project based on .Net 3.5, there is a line chart in this project as the follow:
I find WPF Toolkit is a free control for chart in wpf, so I write code as the follow:
xmlns:datavis="clr-namespace:System.Windows.Controls.DataVisualization;assembly=System.Windows.Controls.DataVisualization.Toolkit"
xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit"<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="10" Grid.Column="1" Grid.Row="0"><charting:Chart x:Name="waitingtasks" BorderBrush="Transparent" BorderThickness="0" VerticalAlignment="Stretch" Title="Waiting Tasks"><charting:Chart.TitleStyle><Style TargetType="datavis:Title"><Setter Property="HorizontalAlignment" Value="Left"/><Setter Property="Foreground" Value="White"/></Style></charting:Chart.TitleStyle><charting:Chart.LegendStyle><Style TargetType="datavis:Legend"><Setter Property="Width" Value="0" /></Style></charting:Chart.LegendStyle><charting:Chart.Axes><charting:LinearAxis Orientation="X" Title="Time" Interval="20" ShowGridLines="False"/><charting:LinearAxis Title="Number of Waiting Tasks" Orientation="Y" Interval="5" ShowGridLines="False"/></charting:Chart.Axes><charting:LineSeries DependentValuePath="Value" IndependentValuePath="Key" ItemsSource="{Binding}" IsSelectionEnabled="True"
AnimationSequence="FirstToLast"/></charting:Chart>But I get an error:
Could not load file or assembly 'WPFToolkit, Version=3.5.40128.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
It's very wired. Nothing to do with WPFToolkit assembly.
Any idea? or Is there other free controls for chart in wpf?
Thanks.

Drag and Drop does not work starting windows 8.1
Hi,
we have a WPF application that runs in a different thread from an activex
var t = new Thread(() =>
{
m_CustomizerApplication = new App();
m_CustomizerApplication.ApplicationArguments = args;
m_CustomizerApplication.DispatcherUnhandledException += new System.Windows.Threading.DispatcherUnhandledExceptionEventHandler(m_CustomizerApplication_DispatcherUnhandledException);
m_CustomizerApplication.InitializeComponent();
m_CustomizerApplication.Run();
});
t.SetApartmentState(ApartmentState.STA);
t.Start();
when running as a standalone drag and drop function just perfect, however starting windows 8.1, we can "catch" the object to drag but starting there all other operations fail (cursor displaying where we drag to, drop action is not being applied, etc.)
we experience it in 2 different WPF application which when in standalone works just perfect and when being raised from an activeX the drag and drop just does not work. any suggestions?

Programatically set focus on the next control
Hi all. I have a WPF Window, and I'd like the user to be able to focus on the next element with just pressing Enter, instead of Tab, but I don't want to write event handlers for every element in the form? Is there a way to programatically tell the window to move the focus to the next element?
Thanks.

WPF Menu Binding Issues.
Hi All,
I want to create a Custom Menu like the screenshot below,
When click the arrow button, it will display the Types. When Click the item, such asEasy, it will display in the TextBox.
What I have done now, I have create the basic style for this menu. But have some issue in Binding,
My source class and ViewModel like this,
public partial class CustomMenu : UserControl
{
public CustomMenu()
{
InitializeComponent();
this.DataContext = new ViewModel();
}
}
public class QuestionType
{
public string Name { get; set; }
public ICollection<QuestionType> Types { get; set; }
}
public class ViewModel
{
public ICollection<QuestionType> QuestionTypes { get; set; }
public ViewModel()
{
QuestionTypes = new List<QuestionType>()
{
new QuestionType() { Name="Completion"},
new QuestionType() { Name="Easy"},
new QuestionType() { Name="MoreType", Types = new List<QuestionType>()
{
new QuestionType() { Name="SingleChoice"},
new QuestionType() { Name="MultiChoice"},
new QuestionType() { Name="Blend"},
} },
};
}
}And I bound to MenuItem,
<MenuItem ItemsSource="{Binding QuestionTypes}"><MenuItem.Resources><HierarchicalDataTemplate DataType="{x:Type local:QuestionType}"
ItemsSource="{Binding Types}"><TextBlock Text="{Binding Name}"/></HierarchicalDataTemplate><DataTemplate DataType="{x:Type local:QuestionType}"><TextBlock Text="{Binding Name}"/></DataTemplate></MenuItem.Resources><MenuItem.ItemContainerStyle><Style TargetType="{x:Type MenuItem}"><Setter Property="Command" Value="{Binding XXXX}"/></Style></MenuItem.ItemContainerStyle></MenuItem>When I run the application, It occurred an exception:
Exception thrown: 'System.Windows.Markup.XamlParseException' in PresentationFramework.dll
Additional information: 'Set property 'System.Windows.ResourceDictionary.DeferrableContent' threw an exception.' Line number '187' and line position '22'.
Another question, When I click the MenuItem, I need to display the Menu Header text in the EditTextBox.
I have uploaded my project on OneDrive. You can download and reproduce this issue.

Working with caret in Text Formatter API
Hello!
I'm creating simple WPF text editor via Text Formatter API. I've already done some of the basic functionality and now I need to add a caret support. I also have a visual caret (just a line with blinking animation) that should be synchronized with rendered text. I found a bunch of methods in TextLine class, such as GetNextCaretCharacterHit , GetPreviousCaretCharacterHit , GetBackspaceCaretCharacterHit . But the documentation information about them is ...quite scarce.Could somebody who has some experience in that field explain how to deal with these methods, because I have almost no idea about that?
I tried to search the information in the internet, but as a result I found nothing.
I would be grateful for any help!

How to create an installer that updates from a website?
First of all, I am a structural engineer, not a real software developer. So, please don't kill me.
I'm developing a wpf software for my field. I've created a website. My software uses a couple of 3rd party components.
(1) How do I create an installer that includes the 3rd party components all in a single installer executable? Because when I publish I get a bunch of files, including the 3rd party components. How do I publish in a way that I only get 1 installer file?
(2) I found
http://autoupdaterdotnet.codeplex.com/ but I'm having a hard time figuring out how to use it. Basically, I want to be able to upload an update to my website and my program would automatically update the next time the user runs the application. Please help?
