Setting DisplayMember has no effect

[OLIVER]

Hello Telerik,

I`m currently evaluating wether the ChartView could fit our needs.

Now I got stuck when trying to give the Y-values displayed in the Chart another format (currency):
I`m setting LineSeries instance properties "DisplayMember" without achieving an effect i.e. the values are displayed the same way as if DisplayMember  was not set (f.e. 4995148.92 instead of 4.995.148.92 €).

This is the code:

public partial class Form1 : Form
{

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        InitChartView();
    }

    private void InitChartView()
    {
        var series1 = new LineSeries();
        series1.DisplayMember = "ValueFormatted";
        series1.ValueMember = "Value";
        series1.CategoryMember = "Category";
        series1.DataSource = Data.GetSomeDataYear1();
        series1.ShowLabels = true;
        radChartView1.Series.Add(series1);

        var series2 = new LineSeries();
        series2.ValueMember = "Value";
        series2.CategoryMember = "Category";
        series2.DisplayMember = "ValueFormatted";
        series2.DataSource = Data.GetSomeDataYear2();
        series2.ShowLabels = true;
        radChartView1.Series.Add(series2);
    }
}

public class SomeChartData
{
    public decimal Value { get; set; }
    public string ValueFormatted { get { return Value.ToString("C", CultureInfo.GetCultureInfo("de-DE")); } }
    public string Category { get; set; }
}

public static class Data
{
    public static IList<SomeChartData> GetSomeDataYear1(){
        return new List<SomeChartData>(){
            new SomeChartData() { Category = "Jan",        Value = 4845741.12M },
            new SomeChartData() { Category = "Feb",        Value = 4345642.41M },
            new SomeChartData() { Category = "März",       Value = 4237854.06M },
            new SomeChartData() { Category = "April",      Value = 4035341.33M },
            new SomeChartData() { Category = "Mai",        Value = 3843723.21M },
            new SomeChartData() { Category = "Juni",       Value = 4125344.42M },
            new SomeChartData() { Category = "Juli",       Value = 4443741.22M },
            new SomeChartData() { Category = "August",     Value = 4645530.42M },
            new SomeChartData() { Category = "September",  Value = 5144431.39M },
            new SomeChartData() { Category = "Oktober",    Value = 5034720.42M },
            new SomeChartData() { Category = "November",   Value = 5030842.98M },
            new SomeChartData() { Category = "Dezember",   Value = 4995148.92M }
        };
    }
}

Thanks in advance &
Best regards

Hello Oliver,

Thank you for wriiting.

I logged the issue in our Public Issue Tracking System. Currently, the rendering system of RadChartView does not support this functionality. For the next version we will extend and introduce the Label rendering and customization functionality. The new label elements will support DisplayMember binding, formatting settings and mechanism for override.

Thank you for your time and cooperation. Your Telerik points have been updated.

Kind regards,
Julian Benkov
