Hi

In my workflow diagram I'm preventing the user from free drawing on the diagram surface.

The workflow XAML looks like that:

<my:Diagram x:Name="wfDiagram" ModificationStart="SelectedOnly" Bounds="0, 0, 2000, 2000" VerticalAlignment="Stretch" ShapeBrush="White"
HorizontalAlignment="Stretch"
AllowInplaceEdit="False" LinkBrush="Green" RouteLinks="True"
LinkSelected="wfDiagram_LinkSelected" LinkDeselected="wfDiagram_LinkDeselected" LinkCreated="wfDiagram_LinkCreated" LinkModified="wfDiagram_LinkModified"
NodeSelected="wfDiagram_NodeSelected" NodeDeselected="wfDiagram_NodeDeselected"
MouseLeftButtonDown="wfDiagram_MouseLeftButtonDown" MouseMove="wfDiagram_MouseMove">
</my:Diagram>


And in the C# I initialize with


////Disable multy select
wfDiagram.Selection.AllowMultipleSelection = false;
wfDiagram.CustomBehavior = new clsNodeCustomBehavior(wfDiagram);
wfDiagram.Behavior = Behavior.Custom;

//Make The routing link better
wfDiagram.RoutingOptions.GridSize = 2;
wfDiagram.RoutingOptions.StartOrientation = MindFusion.Diagramming.Silverlight.Orientation.Horizontal;
wfDiagram.RoutingOptions.EndOrientation = MindFusion.Diagramming.Silverlight.Orientation.Auto;
wfDiagram.RoutingOptions.Anchoring = Anchoring.Keep;

Where clsNodeCustomBehavior Is
public class clsNodeCustomBehavior :BehaviorBase
{

public clsNodeCustomBehavior(Diagram diagram)
: base(diagram)

{

}


public override InteractionState StartDraw(Point point)

{


DiagramNode node = Diagram.GetNodeAt(point);


if (node != null)



return new InteractionState(node, MindFusion.Diagramming.Silverlight.Action.Modify, 8, point);



return null;

}
}


Now, when the user adds a few nodes with routing links and then perform the following action:

1. MouseDown on the diagram in an empty place (no nodes or links).
2. Quick drag, while the mouse button is down through some routed links

What happened is that the routed links get all messed up ???
Any Idea why that happen and is there a fix for that ?

Hope I was clear enough

Many thanks

Hai

Not much....
If I'm in "drag the entire workflow" mode than I manipulate th cursor

       private void wfDiagram_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
       {
           if (_bDraggingWorkspace == true)
           {
               Cursor = Cursors.Hand;
               wfDiagram.Cursor = Cursors.Hand;
           }
           else
           {
               //wfDiagram.Behavior = Behavior.DoNothing;
           }
       }

       private void wfDiagram_MouseMove(object sender, MouseEventArgs e)
       {
           if (_bDraggingWorkspace == true)
           {
               Cursor = Cursors.Hand;
               wfDiagram.Cursor = Cursors.Hand;
           }
       }

But in the scenario that I've pointed _bDraggingWorkspace = false... so nothing actually

Thx

I wish I could, but not at the moment... Our project is Huge...
I may be able to do It on sunday... I just though that maybe you can think of something that I do that could create this kind of behavior....

I'm not moving a link or a node... I click on an "Empty" area of the diagram.


It's a bit similar to if I was painting a shape through the routed links so they would have reposition themselves but this is not the case because I do not paint nothing....

Just hoped that you will have something in mind...
(Stoyan is quite farmiliar with what I did with your control along the way... if you are not him, maybe you can consult )

I have a property panel that I show hide and update.

       private void wfDiagram_NodeDeselected(object sender, NodeEventArgs e)
       {
           HideProperties();

       }

       private void wfDiagram_LinkDeselected(object sender, LinkEventArgs e)
       {
           _dlnkCur_Sel_Link = null;
           //Clear Properties
           panelProperties.Children.Clear();


       }

       private void HideProperties()
       {
           _dnodeCur_Sel_Node = null;
           //Clear
           panelProperties.Children.Clear();
           grdShoHideProperties.Visibility = Visibility.Collapsed;
       }

Any idea what can cause my srange behaviour ?

Well... thanks for the effort...
I'll do my best to do it soon 

Our developer will check it today.

I've used the second one...
Yooooppppeeeee... it works



Thx
