How to know ActualHeight from shape?

[Mikel]

Hello,

I want to align some custom shapes vertically from my diagram.  I make a method called AlignShapes inside a class inheried from SerializableGraphSourceBase<Shape_VM, Link_VM>, and this method is invoked always when InternalItems Changed.

I have create my custom shape class, inherited from NodeViewModelBase and I give it 2 properties, Height and Width (double), that I binded these properties in XAML. Depend of the custom shape, height value is NaN for auto-size, then, when I get the value from custom shape, it return NaN, but the shape in the diagram has a specific height value that I do not know to get.

 How can I get Shape ActualHeight?

 

Thank you!

Hello Mikel,

To get a Shapes' actual size runtime you can use Bounds, ActualHeight and ActualWidth properties. Let us know if this helps you move forward.

Hi Petar!

 

I make AlignShape() in View class, that class has access to RadDiagramShape, and RadDiagramShape has access to ActualHeight, and the value of that property is 0.  :( I dont know why happen that.

I take a picture in debug mode of object value. How can I get real height of the shape?

 

Thank you, Regards!

Hi Mikel,

I guess you invoke this method too early and the shapes are not rendered yet. Is this the case ? When do you call the method ? You can try calling it in Dispatcher.BeginInvoke(()=> call).
