I droped a PrintRibbonControler on a form, and set PrintControl MarginChanged event, but it doesn't fire. When user change the margin on Ribbon control, nothing happens.

That is the right event to catch?

Hi Robson,

I've tested and it works for me. For example, try the following code:

printControl1.Margin = new Padding(20);

Probably, you want to handle an event, when page margins are changing? If yes, you need to handle PrintingSystem.BeforeMarginsChange and PrintingSystem.AfterMarginsChange events instead:

printControl1.PrintingSystem.BeforeMarginsChange += new MarginsChangeEventHandler(OnMarginsChanged);
printControl1.PrintingSystem.AfterMarginsChange += new MarginsChangeEventHandler(OnMarginsChanged);

private void OnMarginsChanged(object sender, MarginsChangeEventArgs e) {
    ...
}

Is this what you need?
