Hi,
I want to migrate a Silverlight 4 application using VS2010, in fact I'm going to start with a page that contains different radchart that interact together, for example if I click in a chart item, I need to refresh the other chart with related information.

My question is, Telerik Silverlight Controls are fully compatible with MVVM? I saw some thread without answer about some event using CallMethodAction. I don't want to start migrating my application if I'm going to have issues with copatibility... Is there any example using events other than click button?, also I found comments in this forum about trying to do an event in the ViewModel without success, but is working fine in the View.

So, if the concept of MVVM is trying to put everything in the ViewModel, I shoudn't have problems moving these events into my ViewModel, Please I need an answer and some examples before start doing the migration.

Thank you very much.

Do you have any example using drill down on RadChart with WPF and Prism. I'm particular interested when I click on the Chart area to drill down that I'm able to capture and publish an event. I know I can use ItemClick in my view.xaml.cs but then I would need to get a reference to EventAggregator and RegionManager,in view.xaml.cs, in order to publish an event. I prefer to capture the click event in my viewModel.cs where I have a reference to EventAggregator and RegionManager but how do I wire up the click event in xaml to go to my viewModel.cs. I'm using version RadControl Q2 2010.

<telerik:ChartDefaultView.ChartArea>

<telerik:ChartArea ItemClick="ChartAreaItemClick" PaletteBrushesRepeat="False" >

</telerik:ChartArea>

</telerik:ChartDefaultView.ChartArea>

//Code behind

protected void ChartAreaItemClick(object sender, ChartItemClickEventArgs e)

{

double StatusCount = e.DataPoint.YValue;

string StatusName = e.DataPoint.XCategory;

}
