bind bar series definition visibility programmatically

[Nemanja]

I'm having trouble adding a binding to the visibility property of the series definition object programmatically. the binding works fine in xaml, but the object doesn't seem to have a SetBinding() function available to it, only a SetValue() - which doesn't set binding, only the value..

is there another way to do this?

i define a series mapping in XAML but allow users to change the chart type which clears the binding. below is the XAML definition:

<rad:SeriesMapping.SeriesDefinition>
                            <rad:BarSeriesDefinition ShowItemLabels="True" ShowItemToolTips="True" ItemLabelFormat="#ProposedSalesQty{#,###,###,##0}"
                                                     ItemToolTipFormat="#AttributeName, #ProposedSalesQty{#,###,###,##0}" Visibility="{Binding ProposedSalesQtySeriesVisibility}">
                                <rad:BarSeriesDefinition.Appearance>
                                    <rad:SeriesAppearanceSettings Fill="SkyBlue" />
                                </rad:BarSeriesDefinition.Appearance>
                            </rad:BarSeriesDefinition>
                        </rad:SeriesMapping.SeriesDefinition>

And in the C# code-behind i attempt to change the value this way:

((LineSeriesDefinition)MixChart.SeriesMappings[0].SeriesDefinition).SetBinding(
                        LineSeriesDefinition.VisibilityProperty, new Binding("ProposedSalesQtySeriesVisibility"));

there is no SetBinding() function so i'm not sure how i can add the binding alternatively? it can be done perfectly in XAML but not sure about code behind...

Thanks,

found a solution on the siliverlight forums...

for visibility, it's just a matter of using the visibilityproperty instead of the one in there...

thanks.
