Did you want some text to be showing the value for the “Desc:” field or property? If so, make sure that TextBlock has a Binding so that it can get the value from your data object.
Yes
I explained it wrong.
I have the field that will receive the value of the choice when it is selected.
But what I want is that when loading the diagram, be inserted in the field corresponding to “Desc:”, the value of the choice, which in this case will be only a value.
I’m going to have to change to that by loading my model myDiagram.model = go.Model.fromJson (data); it needs to populate the fields with their respective values in the text property.
