Multiple objects

May 15, 2010 at 2:33 AM


Is there a way to aggregate properties into a PropertyGrid control, for instance from multiple simultaneous objects at once?

There are two aggregation strategies that would be useful depending on the circumstance:

- Display the union of all properties of all selected objects. (This is very useful for batch editing multiple selected objects, say in an editor.)
- Display only the properties that are common to all selected objects.

I understand there is a design barrier to this, because the property controls may need to be aware of conflicts and convey a ghost state when properties of the same name and return type have conflicting data. But the payoff is potentially huge for certain tools.


Just in case I am missing a native approach: Is there an elegant way to achieve the same effect in C#4 (or even better 3) by exploiting dynamic objects instead of requiring special handling code in the PropertyGrid?  ie. build a dynamic object on the fly that is the aggregate of all individual object properties?

I think this is not so hard to implement, but we need a Property if we show the Properties for the Object collection, or the Properties for the Object's in that collection!

I'm looking for this next week!

Hi jogi,

Are you saying that you are thinking of implementing aggregation strategies as custom property editors?


Thank you.
