MVVM - Legend Label Binding

[Icarus]

Hi, 

I am working with MVVM on a Telerik piechart

I have a Dictionnary<string, int> which I would like to represent with a piechart. The value could easily be represented on the piechart but the problem is the keys of the dictionnary are not considered as legend labels. How can I fix this problem?

<telerik:RadChart Margin="15,15,15,15" Grid.Row="0" Grid.Column="1"  HorizontalAlignment="Center" Background="Transparent" BorderThickness="0" FontSize="10" ItemsSource="{Binding Path=RightTopCollection}" >

    <telerik:RadChart.DefaultSeriesDefinition>

        <telerik:PieSeriesDefinition >

            <telerik:PieSeriesDefinition.InteractivitySettings >

                <telerik:InteractivitySettings HoverScope="Item" SelectionScope="Item" SelectionMode="Single" />

            </telerik:PieSeriesDefinition.InteractivitySettings>

        </telerik:PieSeriesDefinition>

    </telerik:RadChart.DefaultSeriesDefinition>

</telerik:RadChart>

// In constructor
 this._RightTopCollection = new Dictionary<string, int>() {{"firstLabel", 4}, {"secondLabel", 25}, {"thirdLabel", 17}, {"fourthLabel", 19}, {" fifthLabel", 7} };


// Class declaration
  #region RightTopCollection
        public const string RightTopCollectionPropertyName = "RightTopCollection";
        private Dictionary<string, int> _RightTopCollection = null;
        public Dictionary<string, int> RightTopCollection
        {
            get
            {
                return _RightTopCollection;
            }

            set
            {
                if (_RightTopCollection == value)
                {
                    return;
                }

                var oldValue = _RightTopCollection;
                _RightTopCollection = value;

                // Update bindings, no broadcast
                RaisePropertyChanged(RightTopCollectionPropertyName);
            }
        }
        #endregion

Hi Icarus,

Please review our demo which uses the MVVM pattern and will help you to get the idea of controlling the Legend Labels.
I hope this gets you started properly.

Hello Icarus,

You can find a sample project attached demostrating a Pie chart databound using Manual Series Mappings.
