Hi

How do I create a delegate like this, from component side?

bool AllowAction = true;
OnAskParentProgramme(this (sender), AllowAction);
if(AllowAction)
{
DoSomething();
}

in soft

OnAskParentProgramme(sender, AllowAction)
{
if this not ok....
AllowAction=false; // disallow
}

You should use a CancelEventArgs or create a new class that derives from it..

Check this link http://jmcilhinney.blogspot.com.es/2009/11/defining-and-raising-custom-events.html and search for ' if (!e.Cancel) ' I think it is just what you are looking for, hope it helps.
