New Post: [Charting] format the Linear Axis

xyzzer — Wed, 22 May 2013 22:40:13 GMT

I really recommend that you ask questions on Stack Overflow. The chart controls are a huge topic and they should work more or less the same as the Silverlight Toolkit ones since I ported them from there. I might not be able to answer all questions very quickly here and SO is a place where it might be easier to find help. Just tag your question with winrt, winrt-xaml, silverlight-toolkit, xaml, etc.

New Post: chart doesn't exist(solved)

csamzhou — Wed, 22 May 2013 04:38:04 GMT

Hi, first of all thanks for such great controls
I want to use the chart control in my application, I got the toolkit installed, and and have these in my xaml :

  xmlns:charting="using:WinRTXamlToolkit.Controls.DataVisualization.Charting"
    xmlns:Series="using:WinRTXamlToolkit.Controls.DataVisualization.Charting"
    xmlns:datavis="using:WinRTXamlToolkit.Controls.DataVisualization">

but when I use<charting: chart it says chart does not exist in the namespace using:WinRTXamlToolkit.Controls.DataVisualization.Charting

There's another reference WinRTXamlToolkit.Controls.DataVisualization I forgot to add
Sorry silly mistake

New Post: [COMException] INotifyPropertyChanged and LineSeries

Nicothekrug — Tue, 21 May 2013 09:21:29 GMT

Hi !
First of all thank you for this great toolkit. It's an impressive work !

I'm currently using the line chart, and I'm facing a problem : everything goes right, but if I my (In)DependentValue which is bound to my LineSeries contains a change notification (INotifyPropertyChanged), the toolkit raise a COMException.

I've found this thread which said that this bug should be already resolved ? I used the last version (1.4.1) of the toolkit from Nuget.

My XAML code :

<toolkitchart:Chart x:Name="AltitudeChart" Height="200">
                    <toolkitchart:Chart.LegendStyle>
                        <Style TargetType="FrameworkElement">
                            <Setter Property="Width" Value="0"/>
                        </Style>
                    </toolkitchart:Chart.LegendStyle>
                    <toolkitchart:LineSeries
                        Title="Altitude"
                        IndependentValueBinding="{Binding Distance}"
                        DependentValueBinding="{Binding Distance}"
                        IsSelectionEnabled="True"
                        DependentRangeAxis="{Binding ElementName=LeftAxis}"
                        IndependentAxis="{Binding ElementName=BottomAxis}">
                        <toolkitchart:LineSeries.DataPointStyle>
                            <Style TargetType="toolkitchart:LineDataPoint">
                                <Setter Property="Height" Value="4"/>
                                <Setter Property="Width" Value="4"/>
                                <Setter Property="Template">
                                    <Setter.Value>
                                        <ControlTemplate>
                                            <local:DetailedPushpin ManipulationDelta="DetailedPushpin_ManipulationDelta" ManipulationMode="TranslateY"/>
                                        </ControlTemplate>
                                    </Setter.Value>
                                </Setter>
                            </Style>
                        </toolkitchart:LineSeries.DataPointStyle>
                    </toolkitchart:LineSeries>
                    <toolkitchart:Chart.Axes>
                        <toolkitchart:LinearAxis x:Name="RightAxis" Orientation="Y" Location="Right">
                            <toolkitchart:LinearAxis.MajorTickMarkStyle>
                                <Style TargetType="Line">
                                    <Setter Property="Stroke" Value="White"/>
                                </Style>
                            </toolkitchart:LinearAxis.MajorTickMarkStyle>
                        </toolkitchart:LinearAxis>
                        <toolkitchart:LinearAxis x:Name="LeftAxis" Orientation="Y" Location="Left" Foreground="White"/>
                        <toolkitchart:LinearAxis x:Name="BottomAxis" Orientation="X" Location="Bottom" Foreground="White">
                            <toolkitchart:LinearAxis.MajorTickMarkStyle>
                                <Style TargetType="Line">
                                    <Setter Property="Stroke" Value="White"/>
                                    <Setter Property="StrokeThickness" Value="1"/>
                                </Style>
                            </toolkitchart:LinearAxis.MajorTickMarkStyle>
                        </toolkitchart:LinearAxis>
                    </toolkitchart:Chart.Axes>
                </toolkitchart:Chart>

And my C# code :

ObservableCollection<AltChartPoint> ChartPoints = new ObservableCollection<AltChartPoint>();
AltChartPoint a = new AltChartPoint(12); 
ChartPoints.Add(a);
a.Distance = 13; <-- Throw exception if the change is notified
...

 public class AltChartPoint : INotifyPropertyChanged
  {
    private double _distance;
    public double Distance 
    {
      get { return _distance; }
      set
      {
        _distance = value;
       //NotifyPropertyChanged("Distance"); <-- Problem is here
      }
    }
}

Thanks in advance,
Nicolas

EDIT : the same exception occured if i try to edit directly the LineDataPoint.DependentValue

New Post: NumericUpDown Control is not working!

I was just modifying it indeed, though it seems to be working for me. Have you modified the template by any chance? I'll try to fix it today.

Hi,

your NumericUpDown control is not working! I installed the latest version with NuGet and when you add the NumericUpDown control the Visual Studio Designer throws the following exception:

ArgumentException: Delegate to an instance method cannot have null 'this'.

at System.MulticastDelegate.CtorClosed(Object target, IntPtr methodPtr)
at WinRTXamlToolkit.Controls.NumericUpDown.OnApplyTemplate()

New Post: How to Create A Simple Line Chart

rodrigocarfer — Sun, 19 May 2013 19:36:04 GMT

Hi, I appreciate a lot your work doing this toolkit, however I'm having a hard time to create a simple Line chart to my Windows 8 App, since there is no documentation it's hard for me to understand what I should do ... I was unsuccessful at running the sample given in the package, so I was wondering if you could help me out just providing a Example of code that creates the Line Chart in the .xaml and the .cs file that includes values to the chart.

Thanks a lot in advance !

New Post: Chart axis label modification

pietras99 — Sun, 19 May 2013 14:56:17 GMT

My target is to disable axis labels in a chart (chart contains three LineSeries). I can't figure out how to modify them. Any ideas or known solutions?
Thanks in advance.

New Post: An accordion control would be nice

Nice, thanks brendan.

New Post: An accordion control would be nice

brendan — Sun, 12 May 2013 08:38:00 GMT

I ended up porting the accordion from SL toolkit to WinRT (http://github.com/brendankowitz/ZeroProximity.Accordion). I removed the ScrollViewer as adding vertical scrolling needs to be a very conscious decision in winrt apps. Obviously you'd want to style it to look decent, but the behavior of the control itself seems good.

New Post: Size of CountdownControl

star8909 — Fri, 03 May 2013 15:36:31 GMT

Hi firstable I want to say thank youuu for this toolkit which is very useful and great for every Windows RT developpers.

Thank you.

New Post: Working example for WriteableBitmap extensions, grayscale?

ehuna — Wed, 01 May 2013 05:30:57 GMT

In the release notes, I see:

WriteableBitmap extensions - darken, grayscale

I downloaded the solution and ran "WinRTXamlToolkit.Sample" to see if I could figure out how to use the WriteableBitmapRenderExtensions(). Unfortantely, when I try to use WriteableBitmapRenderTestPage.xaml, the app crashes on line 37 of the code-behind:

            wb = await WriteableBitmapRenderExtensions.Render(this.source);

New Post: LineSeries Y axis values

Thraeyll — Tue, 23 Apr 2013 08:52:36 GMT

Hi!

I use the charts of the toolkit and it works really great but i've just run into a problem.
The independent (Y) axis of my LineSeries has a lot of values so those are fading each other. Is it possible to don't show all the values on the axis but for example every 5th of them?
I tried to modify the source code but sadly I was not able to reach my goal.

Thanks!

New Post: Binding chart to observable collection and removing items

albdvm — Sun, 21 Apr 2013 16:56:13 GMT

Hello and great toolkit! Thank you.
I do not have problems with animations but i have noticed that if i am switching between databound Lineseries in xaml and one does not contain any items, the line is not removed from the chart although the datapoints are hidden.
I worked around this by adding a 0 value datapoint in the observablecollection if the count is 0 and reassigning the itemssource in code behind.
I assume this is a bug. Could I be notified when a fix is implemented? or am I doing something wrong?

Thank you!! :-)

New Post: Charting: Would be a good idea to allow multiple stacked column series per entry.

It should be possible to have multiple column stacks side by side per entry, Thomas Guilbault showed how here:

New Post: Field Validation Always Loads as Invalid

kruzty — Thu, 18 Apr 2013 14:33:47 GMT

When I add a field validation extension of NonEmpty to a TextBox and bind to a value (or even put some static text in the Text property), the box displays as invalid until I edit the text in the box.
As a test, I set the validation type to Any changed it to NonEmpty after a button press. This shows the proper validation result. Something similar can be seen in the designer if you have text in the text box - when it is first loaded it shows as invalid, but if you do something to cause a change and the designer view updates, it shows as valid.

Is there an issue with validation when the control is initially loaded, or am I doing something wrong?

New Post: NumericUpDown can not bind Value

yetsen — Thu, 18 Apr 2013 09:50:57 GMT

oh, just found it need to set Mode=TwoWay to make it work, but Slider don't need this.

why don't NumericUpDown behave like other RangeBase controls?

Thanks

New Post: NumericUpDown can not bind Value

yetsen — Thu, 18 Apr 2013 02:47:11 GMT

NumericUpDown seems to be unable to bind, e.g. the following code won't work

<ctrl:NumericUpDown Value="{Binding Attack}" />

but if you change NumericUpDown to Slider, it works

<Slider Value="{Binding Attack}"/>

what am I missing?

Thanks
