ChartPanAndZoomBehavior zoom and pan together

[Zberbang]

Hello all!
I want to have Zoom and Pan behavior together on one chart:

<telerik:RadCartesianChart.Behaviors>
<telerik:ChartPanAndZoomBehavior DragMode="Zoom" ZoomMode="Both" />
<telerik:ChartPanAndZoomBehavior DragMode="Pan" PanMode="Both" />
</telerik:RadCartesianChart.Behaviors>

If I do so, zoom behavoir is not working properly - no zoom inside rectangle occurs.
Is it possible to do? Or may be it id possible to activate Pan behavior only when Ctrl is pressed?

p.s. I'm using Q2 2013 demos.

Hi Les,

RadChartView controls (RadCartesianChart, RadPolarChart and RadPieChart) require that only a single instance of each chart behavior type is present in the Chart.Behaviors collection. Having more than one ChartPanAndZoomBehavior (for example) is undefined.

I would recommend leaving only the second ChartPanAndZoomBehavior definition, and using the KeyUp and KeyDown events to toggle the DragMode to Zoom and back to Pan (when for example Ctrl is pressed / released).

I have attached a sample project to demonstrate.
