Hi Rajesh,

Set your links Style to Cascading if the problem is that the link angle changes while a node is being dragged.

Stoyan

Routing is done automatically only after the node is dropped. You might try calling link.Route for all links connected to a node in response to the NodeModifying event.

Stoyan

Route() returns false if it can't find any path. Is there any other node in the background at the point where the result is false?

Hi Stoyo

Ya. Its true when I try to move the node outside the diagram bounds link.Route returns false.

But false value is retuned only if I try to move on left side of the diagram. Moving item on right side works property and Link.Route() returns true.

Please have a look in following image.


In this Image, in first 3 images one can move node anywhere and link routing works properly but in 4th image it fails when moved out side the diagram bounds. ( As you see moving outside the diagram bounds worked in second image).

I tried to change the bounds of image in node modified event and some times it works proeprly. But changing diagram bounds i have another problem like below -
Changing bounds of diagram shows scrollbar. To show the diagram centrally, I changed bounds in all directions. In this situation if user now tries to move the node in side the bounds I can't change the bounds again ( In this situation i need to consider position of other nodes) and scrollbar  can't be removed.

In the image, 2nd image is my original image and repositioning the nodes I gets images like 1,3 and 4th.

I guess, operation shown in 4th should work similar to image 2.

Regards
Rajesh

Hi Stoyo

I didn't specified any link routing explicitly. The default one is getting used.

I am also not using any specific layout. The node are positioned with explcit calculation.
