Hi All,

I am trying to highlight the active node when the HandleStyle property of the node is set to MoveOnly.
I referred   to the following discussion from the forum. The suggestion is as follows :

" You could set the Brush to highlight the node, or set HandlesStyle = Custom and draw the selection frame as you need it from the DrawAdjustmentHandles event handler. "

But the problem is I cannot use the first suggestion related to setting the brush of active node. Can someone please provide few details how to incorporate the second suggestion.

Thanks,
Shane.

Hi Stoyan,

That reference has provided a lot of help and the functionality is running fine.

I also have a functionality to lock the movement of the node on click of a button the code used by me for the purpose is as follows :

void diagram_NodeStartModifying(object sender, NodeValidationEventArgs e)
       {
           if (lockNodeMovement)
           {
               e.CancelDrag();
               diagram.OverrideCursor = Cursors.Arrow;
           }
           else
           {
               diagram.OverrideCursor = null;
           }
       }

By integerating the code the node movement is distorted i.e when nodes are selected and user tend to move them by dragging the mouse then nodes mutual alignment get distorted.

I have set the HandleStyle property of the nodes as custom.

Any suggestions how can I fix this.

Thanks,
Shane.

Hi Stoyan,

Yes I have already tried that approach but its not working thats why I used the method from my last post.

Can you suggest another approach.

I am also using this method in my code.

     void diagram_SelectionMoving(object sender, ValidationEventArgs e)
       {
           if (lockNodeMovement)
           {
               e.CancelDrag();
               diagram.OverrideCursor = Cursors.Arrow;
           }
           else
           {
               diagram.OverrideCursor = null;
           }
       }

Thanks,
Shane.
