Serialize 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.
