How to disable automatic layout of elements in RadDiagram, after the Layout function is invoked?

Good afternoon,

When we add a new child element to the RadDiagram(see attach file), the diagram automatically optimizes their layout. After the chart is updated, the new element and its parent are automatically moved to the left side. How to make them stay in their places?

There is a small discussion of this problem on the forum.

Regards,
Andrei Silich

Hello Petar,

Yes, that's right. We need an API that would allow us to disable automatic sorting of components after calling "Layout". To keep the components in place.

Hi Andrei,

Ok let me summarize the requirement and if you agree, I will log it on your behalf with different name and will decline this one (redirect it to the new one).

    - You have initial tree layout which sorts the individual components of connected shapes horizontally. Sort is first by the number of nodes in component (decreasing), then by the width of the component decreasing. This part does not need change in the Diagram.

    - you add nodes to some components. You need API to call Layout which will 'tree down' the edited component but do not sort again the individual components ?

Hello Petar,

i can't give a working project, it's huge. I have attached several files to arhiva.

Every time I add or remove a chart element, I set property "SourceItems"  in the IdentDiagramViewModel and call a method of diagram "SetLayout".

Hello Andrei,

Can you add sample or at least code files, instead of pictures ? If not easy to provide, can you point where do you call the Setlayout() funciton, is it called when a new item is added ?

Hello Petar,

AutoLayout property is False.

I attached images with XAML and ViewModel of diagram.

Hello Andrei,

In the mentioned thread I asked whether you use AutoLayout property to True ? Can you add more specific details regarding your scenario in case we are missing something - how do you populate the diagram (Items or GraphSource), how do you add items, etc.
