SaveToXml / SaveToString with TemplatedNode (Read 1924 times)

	I have a diagram with TemplatedNodes. Each TemplatedNode can have a different Template assigned so that they show up differently on the diagram. I've called diagram.SaveToString(SaveToStringFormat.Xml, true) and then later with that string, called diagram.LoadFromString(diagramString) The correct number of nodes show up and are placed in the correct locations, however they do not seem to have their Template assigned anymore. How do I get the Template to be saved in the XML string? Thanks, Joel.

	Saving templates is not supported. Consider using style triggers instead - Code <Style TargetType="{x:Type diag:TemplatedNode}"> <!-- default template --> <Setter Property="Template"> <Setter.Value> <DataTemplate DataType="{x:Type diag:TemplatedNode}"> <Rectangle Fill="Chocolate" /> </DataTemplate> </Setter.Value> </Setter> <Style.Triggers> <!-- template based on tag value --> <Trigger Property="Tag" Value="Ellipse"> <Setter Property="Template"> <Setter.Value> <DataTemplate DataType="{x:Type diag:TemplatedNode}"> <Ellipse Fill="LightGreen" /> </DataTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> Now if you use Tag or another property serialized with nodes as a trigger, it should apply the templates also after loading.

	Thanks! I was already using Tag for something else, but not the Text property. So assigning that a meaningful string and triggering off it works great.
