DirectedTreeLayout doesn't allign nodes automaticaly

[Vladimir]

Hello everyone,

It seems that DirectedTreeLayout  doesn't allign nodes automaticaly, if Nodes and Connectors are bound to ViewModel properties.

I've prepared a demo app, where the issue is shown.  It's just a simple app where only one view and one view model, nodes are created on view model side etc.

PS: If I call "Diagram.LayoutManager.Layout.UpdateLayout();" right after creation of nodes, it does work. Should it be applied automaticaly, shouldn't it?

thanks in advance.

Hi Vladimir,

It is by design that SfDiagram WinRT updates the Layout in its loaded event (i.e. Data for Layout are assigned before that). After analyzing your sample, we came to know that Data for Layout is assigned in Page loaded event (after Diagram is loaded). So, the Layout does not get refreshed. In order to solve this problem, Layout can be updated manually after data assigned.

Please let us know if you have any concerns

Hi,

thanks you for the response. 

so, if it does not apply automatically , then it creates a node somewhere on a random position and only if I call ApplyLayout it will be realigned. right? It doesn't make much sense to me.  I would definitely like to see this feature released. :)

regards,

Vladimir.
