We need to restrict user from resizing as by resizing the diagram is getting spoiled and saved
no control for user actions for selected shapes

This is my solution to remove the connector Auto for all shapes:
        <telerik:RadDiagram ID="myDiagram" runat="server">
            <ShapeDefaultsSettings>
                <ConnectorsCollection>
                    <telerik:DiagramShapeConnector Name="Bottom" />
                    <telerik:DiagramShapeConnector Name="Left" />
                    <telerik:DiagramShapeConnector Name="Right" />
                    <telerik:DiagramShapeConnector Name="Top" />
                </ConnectorsCollection>
            </ShapeDefaultsSettings>
        </telerik:RadDiagram>

I have use this for a floor plan, it look good. 
If I select one of the shape, how can I read the shape ID, can it be done?

How about disabling editable attributes for individual shapes instead of entire diagram?

most excellent. thank you!

That did the trick. Thanks!

Hi all
Try this , it seem like i found the way to prevent resize & rotate :

    	<telerik:RadDiagram ID="theDiagram" runat="server" Width="1000" Height="800" Skin="MetroTouch" >                
               <ShapesCollection>
                    <telerik:DiagramShape Id="Rule" Type="rectangle" Editable="false" X="230" Y="70" Width="100" Height="40" >
                         <FillSettings Color="#fcdcdc" />                         
                         <ContentSettings Text="Rule" Color="#010101" />     
                        <StrokeSettings Color="#000000" DashType="Solid" Width="2" />                                        
                    </telerik:DiagramShape>
                    <telerik:DiagramShape Id="Condition1" Type="circle" Editable="false" X="70" Y="270">
                         <FillSettings Color="#e26c60" />
                         <ContentSettings Text="Condition-1" Color="#fff" />
                    </telerik:DiagramShape>
                    <telerik:DiagramShape Id="Condition2" Type="circle" Editable="false" X="390" Y="270">
                         <FillSettings Color="#e26c60" />
                         <ContentSettings Text="Condition-2" Color="#fff" />
                    </telerik:DiagramShape>
					<telerik:DiagramShape Id="Conditions" Path="M37.50,0.50 L74.50,28.76 L60.35,74.50 L14.65,74.50 L0.50,28.76 z" X="230" Y="170">
                         <ContentSettings Text="Conditions" />
                    </telerik:DiagramShape>
               </ShapesCollection>
                <ConnectionsCollection>
                   <telerik:DiagramConnection>
                        <FromSettings ShapeId="Rule" />
                        <ToSettings ShapeId="Conditions" />                      
                   </telerik:DiagramConnection>
                   <telerik:DiagramConnection>
                        <FromSettings ShapeId="Conditions" />
                        <ToSettings ShapeId="Condition1" />                      
                   </telerik:DiagramConnection>
                   <telerik:DiagramConnection>
                        <FromSettings ShapeId="Conditions" />
                        <ToSettings ShapeId="Condition2" />                      
                   </telerik:DiagramConnection>
                </ConnectionsCollection>
                <EditableSettings Resize="false" Rotate="false"> </EditableSettings>                
          </telerik:RadDiagram>

I need the ability to disable these editable attributes as well. Resize and Rotate specifically. Any update?

Is this feature is available in the last release?

Making shapes not resizable/draggable would be very useful so that I can use RadDiagram to render Sankey diagrams. The properties are there now, but do not seem to have any effect.
Also It implementing a 'visible' property on shapes would be very practical: you create all shapes beforehand and switch them on and off according to certain conditions. (now you have to remove them from the shapes collection to achieve this).
thnx

Hi,
I want to disable resize, delete, drag and edit functionalities of diagram/shape/connector.
In other way, I need a kind of read only diagram. There would not be interaction with end user or end user should not change the structure of the diagram or data in any way. But user should be able to click on a link in the data if there is any.

Thanks,
Sandeep

this absolutely has to be implemented -- everywhere in life we have diagrams that are not for manipulation. if we're to use RadDiagram as a replacement for static images or HTML hacks, then making it read-only is a basic, missing feature.

as for my customers, we're using RadDiagram to produce a rich diagram representing facility pipleline systems and use the Connection stroke properties to give visual indicators of real-time flow rates and blockage statuses (green pipes/connections, red pipes/connections, etc). Users can hover or click the Connections (using a hack) to pull up additional info. But my users are confused because they can accidentally enter text-entry mode, or drag Shapes or text labels around... 

once we get this, and IDs for Connections, this will be a tool to be reckoned with!

thanks!
