How to bind Stencil Symbol Source

[tomer]

Hi,

In the following articles

https://help.syncfusion.com/wpf/sfdiagram/stencil

There is an example of creating symbols

But in one of the samples you can find the following code

 <stencil:Stencil.SymbolSource>

                    <local:SymbolCollection>

                        <!--BasicShapes-->

                        <local:NodeVm UnitWidth="60" UnitHeight="60" 

                                      Shape="{StaticResource Rectangle}" Key="Basic Shapes">

                        </local:NodeVm>

                    </local:SymbolCollection>

                </stencil:Stencil.SymbolSource>

NodeVm doesnot implmement ISymbol as mentioned in the article

How can i bind SymbolSource  to a collection of NodeVM from my view model?

Thanks in advance

Hi Tomer, 

 

We have deprecated the ISymbol dependency with SymbolSource and Stencil , in order to provide support to add Node and Connector into Stencil. We have Provided the sample and online documentation link. Please refer to sample and documentation link as below.

Thanks

But i dont see binding here

I was talking about something like

<stencil:Stencil x:Name="stencil"

                             SymbolSource="{Binding Shapes}"

Where the Shapes is a property in my view model of type ObservableCollection<NodeViewModel>

I have tried it and it throw exception

Thanks in advance
