Constraints enable or disable certain behaviors of the diagram, nodes, and nodes, etc.,.

Inheritance
System.Object
DiagramConstraints
Namespace: Syncfusion.Blazor.Diagrams
Assembly: Syncfusion.Blazor.dll
Syntax
public sealed class DiagramConstraints : Enum
Remarks
The constraints are enabled or disabled using bitwise operators. The constraints are disabled using ‘~’ bitwise operator.
The constraints should be set in the Constraints of the SfDiagram.
The following links might be useful in understanding the Constraints in the diagram.
1. AnnotationConstraints
2. BoundaryConstraints
3. ConnectorConstraints
4. NodeConstraints
5. PortConstraints
6. SnapConstraints
7. SelectorConstraints
The following code snippet is an example to set diagram constraints as default and page editable.
Examples
<SfDiagram Height="600px" Nodes="@NodeCollection" Constraints="@DiagramConstraints">
</SfDiagram>
@code{
//Sets the Diagram constraints...
DiagramConstraints DiagramConstraints = DiagramConstraints.Default & ~DiagramConstraints.PageEditable;
   ObservableCollection<DiagramNode> NodeCollection;
   protected override void OnInitialized()
   {
       NodeCollection = new ObservableCollection<DiagramNode>();
       DiagramNode Node = new DiagramNode()
       {
           Id = "node1",
           Height = 100,
           Width = 100,
           OffsetX = 100,
           OffsetY = 100,
       };
       NodeCollection.Add(Node);
   }
}
