Hi,
The SimpleFiltering example binds the visibility of a data series to a view model via XAML, eg.:
How can I achieve the same functionality via code (I'm coding in Visual Basic)? I'm buidling my data series dynamically through code, however I haven't able to figure out how to bind the visibility property via code.
Kind regards,
Dave.

Hi Evgenia,
I'll ask my question in a different manner: How do the write the following XAML in code instead:
I can't figure out how to bind the visibility property of a data series in a chart to a property in a view model.
The other thread you referenced enquired about how I can save and retreive a property in the view model, however this thread asks how to bind a property in the chart control to a view model in code instead of XAML.
Kind regards,
Dave.

Hello David,
Now I get your question. Sorry for the misunderstanding. The SeriesDefinition.Visibility property is not a dependency property so you cannot use a binding expression to assign its value. Note that this cannot be improved at the moment as in Silverlight the binding target can be a DependencyProperty of a FrameworkElement only (not a generic DependencyObject) and the SeriesDefinition is a generic DependencyObject.
If you insist on creating the Simple Filtering demo in code-behind - refer to this forum post.

Hi Evgenia,
Thanks for the clarification with the property and link to the previous forum post - I had not found it previously because it was in the Silverlight forum instead.
Kind regards,
Dave.
