RadDiagram does not render stroke thinner than 2px.

Code to reproduce:

        <telerik:RadDiagram ID="webDiagram" runat="server">
            <ShapesCollection>
                <telerik:DiagramShape Id="s1">
                    <StrokeSettings Width="1" Color="grey" />
                </telerik:DiagramShape>
            </ShapesCollection>
        </telerik:RadDiagram>

Actual result:

Expected result:

The connection StartCap and EndCap values are not applied when set through ConnectionDefaults.
The bug is introcuded version 2016 R3 SP1

When more than one shapes have HTML content containing image with the same path, only the image inside the first shape is rendered:

Hi!

We would like to create end user possibility to change diagram type.

It would also be nice to be able to searilize all settings from the diagram component.

Is this possible or is it a planned feature?

Best regards
Henric

You should be able to prevent the horizontal/vertical overlapping of routed connections . This way the connections should be easier to differentiate.

1. Could this be a setting where there is no overlapping of connections?

2. Even if I use a different color (red) for HoverSettings only the most recent created connection is displayed.  At make the selected (Hovered) selection show when clicked.

3.  This is a show stopper for us.  We might have to try a different product because our clients need to differentiate the different paths (connections) in a complex Diagram.

There is a similar request for this same missing feature in your other products at
https://feedback.telerik.com/Project/143/Feedback/Details/134524-diagram-add-a-way-to-prevent-overlapping-of-routed-connections

It would be great to be able to highlight all shapes that are connected to a shape that is clicked by the user.

With RadDiagram it's possible to have a shape connected to it self through ConnectionsCollection DiagramConnection declaration. 

But it would be nice if the diagram end user, using the built-in drag and drop could connect a shape to it self like it does between different shapes.

Thanks

Diagram nesting.

I want to develop a tool with a UI similar to Microsoft SQL SSIS Designer or Visual Studio DGML. (Architectural diagrams) 
Using the Diagramming Framework is close. But it needs some way to drag a container object onto the surface, connect it to other objects or containers. This container (group) could contain other objects or other sub-container objects. 

Thus I get a potential infinite nesting of things that can contain a group of things  which have a relationship between them. (a mini-diagram)

I'd also need a Drag/Drop event & Expand/Collapse event. My goal is to let the users draw a workflow of parallel & sequential tasks. As they change the diagram the database is updated. This drives a process which is my application. 

These types of hierarchical relationships are very common. 

Example: Manufacturing. 
The Diagram of a Process building an assembly, which contains Sub-Assemblies, which also need to be constructed.  

Example: Computing
Showing a group of scheduled tasks which can be run in parallel. But the whole group needs to be complete prior to the next group of tasks being started. (similar to a milestone)

Example: Database Object Diagram. 
Showing the relationships between tables, views & stored Procedures. But each box has a little Expand button that lets you see the indexes, triggers & Constraints that define the table.

Currently the Telerik Diagram control lets me group objects, But I can't see that grouping. I can't draw a link betwen that group & another nor can I expand / collapse the container object.  

FYI, 
1. Doesn't matter if it is WinForm, WPF, or HTML. 
2. The DGML spec that is implemented in MSFT Visual Studio does all the things I want. Except "installing VS" is a lot of overhead for my solution. 

The property should be similar to the Kendo UI property - http://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/diagram#configuration-connectionDefaults.type

When binding shapes of RadDiagram from a data source, it will be possible to pass the color for the shape's content text.

When you use the ConnectionDataSource of RadDiagram to data bind an SqlDataSource to its connections, a NullReferenceException is thrown.

You can avoid this issue by using ConnectionDataSourceId instead.

When binding connections of RadDiagram from a data source, it will be possible to pass their content Text values.

It will be possible to create shapes of RadDiagram by selecting from a toolbox of specified shape types. 

It will be possible to move RadDiagram shapes via the direction keyboard buttons.

Make it possible to drag RadDiagram shapes in mobile devices.

It will be possible to specify the maximum number of connections that start from a shape and end in a shape of RadDiagram.

It will be possible to edit the content of shapes and connections of RadDiagram by interacting with them.
