Winforms Diagram - Detect Magnification/Zoom change

[Howard Birkett]

How do I detect a change in the magnification of a diagram view, possibly caused by the overview control. I can't find an event to hook (but I could be blind)

Thanks
Howard

Hi Howard,

Thanks for your interest in Syncfusion products.

We suggest you to use the Diagram.Eventsink’s “MagnificationChanged” event to achieve your requirement.

Here is the Code snippet:
[C#]
this.diagram1.EventSink.MagnificationChanged += new ViewMagnificationEventHandler(EventSink_MagnificationChanged);

void EventSink_MagnificationChanged(ViewMagnificationEventArgs evtArgs)
{
MessageBox.Show("New Magnification value: " + evtArgs.NewMagnification +" "+" Old Magnification Value:"+evtArgs.OriginalMagnification);
}

For more information, please visit the below online documentation UG link:

For your convenience, we have modified the sample to achieve your reuirement.
