Hello,

When I set the content of a control to a RadChart created in code behind, it works in all cases except with the Pie and Doughnut chart.

The issue is nearly identical to the one posted here:
http://www.visifire.com/forums/lofiversion/index.php/t832.html

I tried to create a sample project to reproduce but it has been quite difficult (meaning it seems to work in this simple standalone project)... I am not sure what is causing this error in the one project. I have eliminated styles, etc., it has not helped.

There is no stack trace given with this exception, eventually the silverlight window goes into overflow and WSOD. The error occurs sporadically after the content is set (so it is not something that can be debugged).

I will keep trying to create a sample to reproduce but was also hoping this may be a known issue or there could be a workaround.

To try to troubleshoot this I took a guess that it was the MeasureOveride and it turned out that was correct. I can catch the exception here on the added chart, however, nothing I seem to do can actually handle it. FYI - the availableSize is {0, 0}

    
                public class RadChartM : RadChart  
        
                {  
        
                    protected override Size MeasureOverride(Size availableSize)  
        
                    {  
        
                        try  
        
                        {  
        
                            return base.MeasureOverride(availableSize);  
        
                        }  
        
                        catch (Exception ex)  
        
                        {  
        
                            Debug.WriteLine(ex.ToString());  
        
                            return new Size(this.ActualWidth,this.ActualHeight);  
        
                        }  
        
                    }  
        
                }

Exception:
System.ArgumentException: Value does not fall within the expected range.

I can reproduce this very easily in our master project but have not been able to repro in a small isolated project. I keep adding more parts to the isolated project to find out what combination creates the issue, but it's time consuming.

I have tried various things within the project to work around the issue.
e.g.
- naming the chart (unique generated name) - same error
- adding the chart to a grid, then setting the content to the grid (same error)
- set the chart visibility to collapsed, then set the content to the chart (ok) then set visibility to visible (crash)
- set the content using Dispatcher.BeginInvoke, same error
- suppressing the exception in MeasureOverride (impossible)
- using an empty List<T> for the ItemsSource (works - but displays "No Data Series" - so useless)

What is the strangest is that the error happens recursively and endlessly until the app dies, there is no way to handle or suppress. Again, all other chart types are working fine.

Hello,

I would like to add myself to the discussion here.
I've the same problem as mentioned here with a Pie chart.
My C# solution is similar to that of Sales Dashboard demo with one of the Modules containing a view with a Pie chart and nothing else, the View is injected in designated region contained in a ContentControl.

The Pie Chart renders correctly in the following 2 separate scenarios:

The Series Mappings, Item Mappings and etc are added via Code Behind. The XAML for this contains only a RadChart declaration like most of the examples on your website.
There are no code in code behind, ItemsSource is bound to view model, and Series Mappings and Item Mappings are declared in XAML but uses default layout.

It doesn't work for me when I don't use default layout , i.e. have a Grid with 3 rows, ChartTitle, ChartArea and ChartLegend each occupying a row in that Grid. There is no code behind and view model provides the data, Series Mappings and Item Mappings are declared in XAML.

Compiling this as a separate app without Unity works without a glitch.

Regards.

Error is reproducible for following code:

I could reproduce it when all the YValues are Zero. As in Below Case Chart Data is Zero for X and Y group.

//Please assume some code. below code is just for reference.

public MainPage()

{

InitializeComponent();

RefreshGraph();

}

private void RefreshGraph()

{

RadChart1.DefaultSeriesDefinition =

new PieSeriesDefinition();// { DefaultLabelFormat = "#%{p1}" };

SeriesMapping sm = new SeriesMapping();

sm.ItemMappings.Add(

new ItemMapping("YValue", DataPointMember.YValue));

sm.ItemMappings.Add(

new ItemMapping("Name", DataPointMember.LegendLabel));

List<ChartData> data = new List<ChartData>()

{

new ChartData(0,"X"),

new ChartData(0,"Y")//,

//new ChartData(27),

//new ChartData(15),

//new ChartData(29)

};

RadChart1.SeriesMappings.Add(sm);

RadChart1.ItemsSource = data;

}

Thanks,
Vinod Sa.
