Class NodeConstraints

The node constraints allow the users to enable or disable certain behaviors and features of the diagram nodes.

Inheritance
System.Object
NodeConstraints
Namespace: Syncfusion.Blazor.Diagrams
Assembly: Syncfusion.Blazor.dll
Syntax
public sealed class NodeConstraints : Enum
Remarks
The node constraints are enabled or disabled using the bitwise operators. The ’~’ operator is used to disable the node constraints.
The following code snippet is an example to set node constraints.
Examples
<SfDiagram Height="600px" Nodes="@NodeCollection">
</SfDiagram>
@code{
  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,
           //sets the NodeConstraints constraints...
           Constraints = NodeConstraints.Default & ~NodeConstraints.Rotate
       };
       NodeCollection.Add(Node);
   }
}
