How do you recognise a cancel operation?

I am changing the brush of a node when it is modifying; however because the grid granularity is quite high, the on Modified event is not getting called as the node has not moved far enough. This means I cant change the brush because the onModified is not getting called...
Or for example i move the node to the bounds of the view - release - and it goes back to its original position. The onModified is not getting called. How can I get this cancel function called?

Thanks guys

We'll have to add a new event to let you do that more easily. Until it's available, you could keep a reference to the item being modified in a member variable of the form class, and restore its brush in response to DiagramView.MouseUp.

I hope that helps,
Stoyan

Thanks Stoyo, that would be great. Yeah I'll have to make some kind of work around.
