I tried to write my own move shape feature.but how can i find that while moving to new location already another shape is existing. Ican try some overlapping algorithams but it will become performance issue for each move.
Is there any other way to find the existing shapes on diagram for specified location.
Please see my blog post regarding this issue. (I still have fewer than 5 messages, that is why I can't post links yet, but you can find the blog here:
