//A control is associated with a behavior collection
//A behavior collection is a collection of behaviors
//A behavior can contains one condition e.g. itemscount = 0 and one or more setters e.g. set the property canexecute =true on control destination. The setter also stores the
//value of the property its bound to (the control and the propert name)
//Behaviors are invoked on the control when a particular activity takes place for e.g. when a selection changes on a listbox control, when text is entered
//on a text control.
//Typical use case for behaviors is as follows. Every control has a CanExecute property. This can be enabled or disabled by default.
//The OK button will only be enabled when the can execute property of all the controls on the canvas are set to true.
//
//For example, when the
//one sample t.test dialog is rendered for the first time, the destination listbox will always be empty. We would then set the default value of canexecute to false.
//We would define a condition for when items count is > than 0 and set canexecute for the destination property to true only when items count is > than 0.
//We would also add another condition to set Canexecute to false when items count is 0 to account for the case when users move variables from the destination
//back to the source.
//Also note that you can have canexecute to true on the destination control of one sample t.test but have the canexecute property on the textbox set to false
//as no valid entry has be entered tocompare the dialog against. In this situation the OK button on the dialog is disabled
// Aaron 12/25 code below ensures that the events don't fire when I am in dialog editor mode.
//This is to address the defect when in dialog mode, the itemscount =3 and the event on the destination list fires to set CanExecute to true
//even though the intention is to save the dialog with CanExecute to False. This will disable the OK button when running the application unless
//one item is in the destination list
