Overview in Demo & Databinding

Hello!

1. I like the overview funktion in the demo with the light tracking rect and the darker area and jumping to this position.

How can I implement this.
I have an overview without this light and dark and i can't jump to that position which i click in the overview.


2. Will there be an release for supporting Databinding for the diagram?

Hi,

1. Set the DimBrush property. Scrolling with the mouse should be enabled by default; check if there isn't some element up in the visual tree stopping the mouse events, e.g. by setting Handled = true from a PreviewMouseXX event.

2. We'll add databinding support at some point, but there are some more useful things we'd like to implement first.

Hi Stoyan,

i have the following code:
Code
Select All
<diag:Overview Name="diagOverview" DimBrush="Beige"/>


and set a connection
Code
Select All
diagOverview.Document = dgDiagram;

to the following XAML Element:

to the Diagramm:
Code
Select All
                        <diag:DiagramView
                            Height="Auto"
                            Name="dvDiagram"
                            Width="Auto" >

                            <diag:Diagram
                                Name="dgDiagram"
                                Background="White"
                                Behavior="DrawLinks"
                                AllowInplaceEdit="True"
                                InplaceEditAcceptOnEnter="True"
                                InplaceEditCancelOnEsc="True"
                                ShowGrid="False"
                                AllowDrop="True"
                                AllowSelfLoops="False"
                                AllowUnanchoredLinks="True"

                                EnableLanes="True"
                                MouseRightButtonDown="dgDiagram_MouseRightButtonDown"
                                LinkHeadShape="Triangle"
                                LinkHeadShapeSize="15"
                                LinkShape="Cascading"
                                DynamicLinks="True"
                                LinkBrush="Black"
                                LinkTextStyle="Center"
                                RouteLinks="True"
                                AllowLinksRepeat="False"
                                ShowHandlesOnDrag="True"
                                NodeActivated="dgDiagram_NodeActivated"
                                NodeDeselected="dgDiagram_NodeDeselected"
                                DragEnter="DragEnterNode"
                                Drop="DropNode"
                                ShowDisabledHandles="False"
                                AutoResize="RightAndDown"
                                >
                            </diag:Diagram>
                        </diag:DiagramView>


I don't see a light tracking rect and when i click in the overview, my Diagram gets a Position at top left.

It seems like i don't get a small tracking rect.

Any hints?

At this time the Overview control supports only ScrollViewer and Ruler as containers of the diagram. We'll try to make it work with DiagramViews next week.
