Hi All,

I need the selected nodes on my diagram to move by pressing the directional keys on the keyboard.

The movement should be in sync of the directional key pressed.

Can someone please tell me how to do that.

Thanks,
Shane.

Hi Stoyan,

Can you tell me how to map the key pressing event and the direction i.e up,down.left and right with this method.

Thanks,
Shane.

Hi,

I am still not able to make it work.

The code used by me is as follows :

In window constructor :

RoutedUICommand cmd = new RoutedUICommand();
           cmd.Text = "move left";
           cmd.InputGestures.Add(new KeyGesture(Key.Left));

           CommandBinding cb = new CommandBinding(cmd, (sender, args) => MoveLeft());
           CommandManager.RegisterClassCommandBinding(typeof(Diagram), cb);
      
MoveLeft method defination :

   private void MoveLeft()
       {
           MoveSelection(new Point(diagram.Selection.Bounds.TopLeft.X+10,diagram.Selection.Bounds.TopLeft.Y) );
       }

MoveSelection method :

private void MoveSelection(Point newPosition)
       {
           Point oldPosition = diagram.Selection.Bounds.Location;
           InteractionState ist = new InteractionState(diagram.Selection, 8, MindFusion.Diagramming.Wpf.Action.Modify);
           ist.Start(oldPosition, diagram);
           ist.Update(newPosition, diagram);
           ist.Complete(newPosition, diagram);
       }

Can you please tell me what is that iam missing.

Thanks,
Shane.

Hi,

Instead of

CommandManager.RegisterClassCommandBinding(typeof(Diagram), cb);

call

d.CommandBindings.Add(cb);

and make sure the move step is larger than GridSizeX.

I hope that helps,
Stoyan
