Class DiagramObject
Represents the base class for all diagram objects in the SfDiagramComponent. This class provides fundamental functionality for property change notifications, parent-child relationships, and object lifecycle management.
Inheritance
Namespace: Syncfusion.Blazor.Diagram
Assembly: Syncfusion.Blazor.dll
Syntax
public class DiagramObject : Object, IDiagramObject, ICloneableRemarks
The DiagramObject class serves as the foundation for all diagram elements including nodes, connectors, and other visual components. It implements the IDiagramObject interface to provide consistent behavior across all diagram objects.
This class manages parent-child relationships through the internal Syncfusion.Blazor.Diagram.DiagramObject.Parent property and handles property change notifications.
Constructors
DiagramObject()
Initializes a new instance of the DiagramObject.
Declaration
public DiagramObject()DiagramObject(DiagramObject)
Creates a new instance of the DiagramObject from the given DiagramObject.
Declaration
public DiagramObject(DiagramObject src)Parameters
| Type | Name | Description |
|---|---|---|
| DiagramObject | src | DiagramObject |
Methods
Clone()
Creates a new diagram object that is a deep copy of the current diagram object.
Declaration
public virtual object Clone()Returns
| Type | Description |
|---|---|
| System.Object | A new DiagramObject that is a copy of the current instance. The returned object has the same property values with a separate instance. |
GetParent()
Gets the parent object of the current diagram object in the object hierarchy.
Declaration
public IDiagramObject GetParent()Returns
| Type | Description |
|---|---|
| IDiagramObject | An IDiagramObject representing the parent object. |
OnPropertyChanged(String, Object, Object, IDiagramObject)
Invoked when the effective value of any property on this diagram object has been updated and propagates the change notification to the parent object.
Declaration
public void OnPropertyChanged(string propertyName, object newVal, object oldVal, IDiagramObject container)Parameters
| Type | Name | Description |
|---|---|---|
| System.String | propertyName | The name of the property that changed. Can be null if the property name is not available. |
| System.Object | newVal | The new value of the property. Can be null if the new value is null or not provided. |
| System.Object | oldVal | The previous value of the property. Can be null if the old value is null or not available. |
| IDiagramObject | container | The IDiagramObject that contains the changed property. |
Remarks
This method implements the property change notification pattern used throughout the diagram framework. When a property changes on any diagram object, this method is called to propagate the change up the object hierarchy.
