<!--Defines the custom connection indicator style for port connection-->
<Style TargetType="Path" x:Key="PortConnectorIndicatorstyle">
   <Setter Property="Stroke" Value="Yellow" />
   <Setter Property="StrokeThickness" Value="2"></Setter>
</Style>
 
<!--Defines the custom connection indicator style for port connection-->
<Style TargetType="Path" x:Key="NodeConnectorIndicatorstyle">
    <Setter Property="Stroke" Value="Yellow"/>
    <Setter Property="StrokeThickness" Value="2"/>
</Style>

//To change the connection indicator style of the node and port connection.
diagram.ConnectionIndicatorStyle = this.Resources["NodeConnectorIndicatorstyle"] as Style;
//Here, diagram is the instance of SfDiagram.

public class Diagram : SfDiagram
{
  protected override void SetTool(SetToolArgs args)
  {
    Console.WriteLine(args.Source);
    if (args.Source is INodePort)
    {
      //To change the connection indicator style of the port connection.
      this.ConnectionIndicatorStyle = this.Resources["PortConnectorIndicatorstyle"] as Style;
      base.SetTool(args);
    }
    else if (args.Source is NodeViewModel)
    {
      this.ConnectionIndicatorStyle = this.Resources["NodeConnectorIndicatorstyle"] as Style;
      base.SetTool(args);
    }
    else
    {
      base.SetTool(args);
    }
  }
 
  protected override void ValidateConnection(ConnectionParameter args)
  {
    var isSourceAction = args.ConnectorEnd == ConnectorEnd.Source;
    if ((isSourceAction && args.SourcePort != null) || (!isSourceAction && args.TargetPort != null))
    {
      //To change the connection indicator style of the port connection.
      this.ConnectionIndicatorStyle = Application.Current.Resources["PortConnectorIndicatorstyle"] as Style;
    }
    else if ((isSourceAction && args.SourceNode != null) || (!isSourceAction && args.TargetNode != null))
    {
      this.ConnectionIndicatorStyle = Application.Current.Resources["NodeConnectorIndicatorstyle"] as Style;
    }
    base.ValidateConnection(args);
