    Hello,

    I'm creating a SeriesMapping in code behind as I need to dynamically change the series in chart depending on a number of other factors.  I need to bind a specific property to my view model, specifically in this case, I need to bind ShowItemsLabel on the SeriesDefinition from code behind.  My code goes something like this:

    seriesMapping.SeriesDefinition = new BarSeriesDefinition() {ItemLabelFormat = "#Y{###,###,##0}"};
    var binding = new Binding("ShowItemLabels");

    The question is how would I use a SetBinding() to bind the new series definition using the two lines above?

    Thanks,

    E.

    Hello EM,

    You can create a binding in code behind and bind the SeriesDefinition.ShowItemLabelsProperty to your view model. SeriesDefinition is the base class for all series definitions and ShowItemLabelsProperty is the dependency property that you'll need for the binding expression. You can use BindingOperations.SetBinding(..) helper method to create the binding in code behind. The final code can look like this:

    SeriesDefinition seriesDefinition = new BarSeriesDefinition() { ItemLabelFormat = "#Y{###,###,##0}" };
    seriesMapping.SeriesDefinition = seriesDefinition;
    var binding = new Binding("ShowItemLabels");
    BindingOperations.SetBinding(seriesDefinition, SeriesDefinition.ShowItemLabelsProperty, binding);

    Now the ShowItemLabels is bound to your view model.
