Chart Legend Items

[Chris Thierry]

Hi,
    I'm using a piechart generating items automatically. How can I access to this collection of items? if I try to use:

myChart.DefaultView.ChartLegend.Items but the count is always 0

Another question: Can I remove the legend click event keeping only the item click?, for example I want to click in a piechart item, the item become exploded but I don't want the same efect if user click on the legend item.  

Thank you.

Hello Chris Thierry,

Due to the specifics of the legend control (we wanted the user to be able to add manually legend items even when the rest are auto-generated -- this is basically not supported out-of-the-box by the WPF/Silverlight control), you need to cast the ChartLegend to its base type to access the items like this (you can call this in the DataBound event handler for example):

(myChart.DefaultView.ChartLegend as ItemsControl).Items

Hope this helps.


All the best,

OK thanks for your answer.
What about the second question?
Thank you.

Hi Chris,

Unfortunately this functionality is not supported at the moment -- it is not possible to restrict the interactivity within the series items only and not the legend items as well.

We will forward your feedback to our developers so they can consider implementing such option for one of the next versions of the control.

Thank you!
Do you know if in the next version we will be able to create a pie chart with an item already exploded?
Thank you again

Hi Chris,

This will be possible -- find attached a sample application that uses the BETA binaries and demonstrates how you can achieve the desired effect.

Hope this helps.
