Hi Experts

We want to add a custom handler on the view range changed event caused by zoom in/out, is there any event we could subscribe? thanks.

Hi Xiaolong,

You can attach to the Scale.RulerRangeChanged event:

chart.Axis(StandardAxis.PrimaryY).Scale.RulerRangeChanged += new EventHandler(Scale_RulerRangeChanged);

...

void Scale_RulerRangeChanged(object sender, EventArgs e)
{
// do something when axis range changes
}

Hi Xialong,

The ruler object is part of the scale, not the scale configurator - take a look at the code snippet more closely...

Hi Xiaolong,

You're right - this event was added in the 2012 edition - you need to upgrade to this version in order to use this event.

Thanks for your reply.

Is there any workaronud in 2011 we could get notified if the view range changed? we need to do some re-sample work for the added series to improve the performance in the event handler.

Hi Xia,

Sorry - there is no equivalent event in 2011...
