Error Saving Chart 2013 Q2 for WPF

[Antonello Giuseppe]

Hello,

I'm trying to save a radchart to a file using the save() method.
No matther what method overload I use I always get an ArgumentOutOfRange Exception with the following description:

[System.ArgumentOutOfRangeException] = {"The parameter value must be greater than zero.\r\nParameter name: pixelWidth"}

I'm not able to figure where to set that parameter in the RadChart.

Documentation on the method does not provide any usage examples and all the old posts on the forum I've found point on this issue to a demo page that no more exist (they point to demos based on chartview now).

Thanks for help

Hi Antonello,

Given only the provided information we are not able to determine the cause of the problem. In order to help you we will need to reproduce the problem on our side, so we can investigate it. It would be best if you could provide a small runnable project. or made modifications to the project that I attached so that it reproduces the problem you are experiencing. 

Thanks for the understanding.

I have got a simple code:

public class ProductSales
{
    public ProductSales(int quantity, int month, string monthName)
    {
        Quantity = quantity;
        Month = month;
        MonthName = monthName;
    }

    public int Quantity { get; set; }
    public int Month { get; set; }
    public string MonthName {get; set; }
}

public sealed class Program
{
    private static List<ProductSales> CreateData()
    {
        return new List<ProductSales>
        {
            new ProductSales(154, 1, "January"),
            new ProductSales(138, 2, "February")
        };
    }

    [STAThread]
    public static void Main()
    {
        var rc = new RadChart();
        var seriesMapping = new SeriesMapping
        {
            LegendLabel = "Product Sales",
            SeriesDefinition = new SplineSeriesDefinition()
        };
        seriesMapping.ItemMappings.Add(new ItemMapping("Month", DataPointMember.XValue));
        seriesMapping.ItemMappings.Add(new ItemMapping("Quantity", DataPointMember.YValue));

        rc.SeriesMappings.Add(seriesMapping);
        rc.ItemsSource = CreateData();
                      // GOT AN EXCEPTION
        var stream = rc.Save();
                      // GOT AN EXCEPTION
        rc.ExportToImage(new MemoryStream());

    }
}

 I don't want hearing anything about XAML! I just want to create Chart in code-behind and get stream of image, but I always got an exception.

Is it possible?

wittily done) but its works for me, thanks.

What about custom theme of chart? Can I change default theme to Metro for example? How?

[Pavel R. Pavlov]

Hello Sergiy,

In your particular case you can use the StyleManager to set the theme. You can set it like this:

StyleManager.SetTheme(chart, new Windows8Theme());

I hope this information is helpful.
