Calling CancelDrag from NodeStartModifying stops both move and resize operations. If you need to stop only move operations, check if (e.AdjustmentHandle == AdjustmentHandles.Move).

Hi Stoyan,

In diagram_PreviewMouseDown event I want to select the node if mouse is over the node. This is working fine for me except in the case when I try to resize the node.

When I resize the node, I get node= null in diagram_PreviewMouseDown event.

Please suggest how I can get node in this event during resize.

Regards,
Anshul

Hi Anshul,

The resize handles might stick a bit outside of the node boundaries, and GetNodeAt disregards adjustment handles, so seeing the mouse cursor change to the resize icon does not mean GetNodeAt will return the node at that position. Instead, use the GetNodeAt overload that takes a threshold argument, and optionally call  HitTestHandle.

Aren't nodes selected automatically when you grab the handle to resize them anyway?

Stoyan

Hi Stoyan,

We have tried with threshold value but it has not solved our problem. We need to change Threshold value according to zoomfactor than only it works. exa:
If we give threshold value 3, it works fine for zoomfactor 50 but not works for zoomfactor 80. Apart from that if two nodes have approx similar bounds than in that case we may get wrong node using GetNodeAt(point,threshold).

Please suggest how to overcome these issues.

Regards,
Anshul
