How can I serialize the custom property of a node?

Essential Diagram supports the custom serialization. To serialize the custom property, you have to derive the Group class and create a custom node. You have to override GetObjectData() method and you can add the custom property in the SerializationInfo. Please refer to the below code snippet.

C#

[Serializable()]

public class CustomNode : Group

{

protected CustomNode(SerializationInfo info, StreamingContext context) : base(info, context)

{

this.m_nodeInformation = info.GetString("strDescription");

}

protected override void GetObjectData(SerializationInfo info, StreamingContext context)

{

base.GetObjectData(info, context);

// Additional member variables are serialized here

info.AddValue("strDescription", this.NodeInformation);

}

}

VB

<Serializable()> _

Public Class CustomNode

Inherits Group

Public Sub New()

End Sub

Protected Sub New(ByVal info As SerializationInfo, ByVal context As StreamingContext)

MyBase.New(info, context)

Me.m_nodeInformation = info.GetString("strDescription")

End Sub

Protected Overrides Sub GetObjectData(ByVal info As SerializationInfo, ByVal context As StreamingContext)

MyBase.GetObjectData(info, context)

' Additional member variables are serialized here

info.AddValue("strDescription", Me.NodeInformation)

End Sub

End Class

Please refer to the attached sample that illustrates this.
