    any news on the WPF ribbon?

    Hi Mathias,

    We’ve been heads down with WPF 4.0 work, but we’ve recently been able to resume our development efforts on Ribbon.  We’re looking to release a new version in the first half of 2010, shortly after the release of Visual Studio 2010.

    This is great!  You know us devs… when will see more controls ported over from SL Toolkit?  MIX2010?  After VS 2010 RTM? I would like to see a Dock Manager control similar to what is used in VS 2010.  I’m still waiting on the controls ScottGu mentioned a few months back regarding WPF Bag O’ Tricks.  Also, when will these new controls be supported by WPF Themes?  Thanks again:)

  4. David Anson says:


    Your passion is great to see! πŸ™‚ I think additional controls will be ported over as time and resources permit. I don’t have any particular insight into when some of this might happen, but I’m going to pass your feedback on to some of the relevant folks internally to be sure these issues are on their list.

    Thanks for the feedback!

    I think it is incredibly important that WPF and Silverlight stay as consistent as possible.

    So where practically possible controls  and themes should be in both toolkits and be as consistent as they can be.

    Missing the lovely BusyIndicator in particular!!!

    Keep up the good work….

    Hi, Is it possible to make step line chart in WPF? and code would be great help

  8. David Anson says:


    It ought to be possible. πŸ™‚ There are some people who have written about creating new series types – you can find all the posts I know about in my charting links collection here:

    Hope this helps!

    I am trying like this creating step line data from normal keyvalue pair. But sometime it creates step line for few points in chart and sometime not. Donot knw why this strange behaviour.

    <chartingToolkit:Chart x:Name="Chart1">


       <chartingToolkit:LineSeries Title="S1" IndependentValueBinding="{Binding Path=Key}"

           DependentValueBinding="{Binding Path=Value}">






     List<KeyValuePair<int, int>> series = new List<KeyValuePair<int, int>>();

     series.Add(new KeyValuePair<int, int>(10, 100));

     series.Add(new KeyValuePair<int, int>(20, 130));

     series.Add(new KeyValuePair<int, int>(30, 150));

     series.Add(new KeyValuePair<int, int>(40, 125));

     series.Add(new KeyValuePair<int, int>(50, 155));

     ((LineSeries)Chart1.Series[0]).ItemsSource = CreateStepLineSeries<int, int>(series);


    List<KeyValuePair<T, U>> CreateStepLineSeries<T, U>(List<KeyValuePair<T, U>> source)


     List<KeyValuePair<T, U>> returnValue = new List<KeyValuePair<T, U>>();

     for (int i = 0; i < source.Count; i++)


       KeyValuePair<T, U> currentValue = source[i];


       if (i < source.Count – 1)


         KeyValuePair<T, U> nextValue = source[i + 1];

         returnValue.Add(new KeyValuePair<T, U>(nextValue.Key, currentValue.Value));



     return returnValue;

    LineSeries sorts its point by IndependentValue, but when two points have the same value, they may not always maintain their original order. I think I’ve seen someone trying to do the same thing and what worked for them was to make sure the new points they added were had *slightly* different IndependentValues. This ensured that they would always sort deterministically in the intended order and gave the pretty step effect they wanted.

    Maybe give that a try?

  11. maverickcoder says:

    Here Mr Bob has sorted out this. Could be beneficial for other guys looking for step line chart in WPF.

    I am trying to remove the dot from the lines in the line chart. But it becomes orange if I change the template of the line.

    Then legend is of no use as all line turns orange.

    <Style x:Key="EmptyPointsStyle" TargetType="{x:Type DVC:LineDataPoint}">

         <!–<Setter Property="Template" Value="{x:Null}"/>–>

         <Setter Property="BorderThickness" Value="1"/>

         <Setter Property="Template">


             <ControlTemplate TargetType="DVC:LineDataPoint">

               <Ellipse StrokeThickness="{TemplateBinding BorderThickness}"/>





    <Style x:Key="EmptyPointsStyle" TargetType="{x:Type charting:LineDataPoint}">

         <Setter Property="BorderThickness" Value="1"/>

         <Setter Property="Template">


             <ControlTemplate TargetType="charting:LineDataPoint">

               <Ellipse StrokeThickness="{TemplateBinding BorderThickness}"/>





    <charting:LineSeries Title="Light" x:Name="myLightChart" DataPointStyle="{StaticResource EmptyPointsStyle}"

                IndependentValueBinding="{Binding Path=Key}"

                DependentValueBinding="{Binding Path=Value}">


    Is this bug ? or any turn around?

  13. David Anson says:


    I discuss the underlying issues here:

    Basically, once you decide to customize the DataPointStyle, that custom Style overrides the automatic Style from the Chart.Palette collection and therefore the custom palette color doesn’t get applied and the DataPoint reverts to its default orange color.

    You can provide a specific Background in your custom Style or copy the default Palette as I describe in that post.

    Hope this helps!
