It will be possible to disable the various actions that the diagram control currently supports. You can find them listed in the following help article: http://www.telerik.com/help/aspnet-ajax/diagram-rich-layout-interaction.html
I'm looking at using RadDiagrams for a dynamic workflow flow dashboard. I'd like to be able to format the text inside the shape with underlines, bolds and line feeds, etc. I'd like to see something implemented like in the report text box where you can pass in an HTML encoded string and when it's displayed it renders it as HTML. <b>Header</b>\n<u>Items</u>
Make it possible to drag RadDiagram shapes in mobile devices.
When you change the beginning or the end of an existing RadDiagram connection and call the client-side save() method, the exported data for the modified connection will not be updated.
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.
RadDiagram throws a NullReferenceException when you bind it declaratively and place it in the ItemTemplate of a data bound control, for example a Repeater.
Does not matter what value is set to the Connection's StartCap/EndCap properties, the ends of the connection are rendered as if the value of these properties is "None".
Add ability to define unique ID for each connection configured in a RadDiagram, so it could be referenced by this ID later.
