Hi,

I'm currently running a feasibility assessment of the Blazor library for our project. I have a created a subclass of the DiagramConnector class with some default properties set. When this is added the symbol palette, and dragged from there the colours and other properties are displayed correctly. However, when the same custom class is used as the DrawingObject it ignores the colours and other properties that are set.

public class ExampleConnector: DiagramConnector
    {

        public ExampleConnector() : base()
        {
            Type = Diagrams.Segments.Orthogonal;
            SourcePoint = new ConnectorSourcePoint() { X = 0, Y = 0 };
            TargetPoint = new ConnectorTargetPoint() { X = 40, Y = 40 };
            Style = new ConnectorShapeStyle()
            {
                StrokeColor = "#FF0000",
                StrokeWidth = 2,
            };
            TargetDecorator = new ConnectorTargetDecorator() { Shape = DecoratorShapes.None };
            Constraints = ConnectorConstraints.Default &
                          ~ConnectorConstraints.Drag;
        }
    }

Hi Simon, 

We have created a simple sample with your code example and we are unable to replicate the reported issue at our end. please refer to the below code example and sample. However, we don’t provide a customization support for blazor diagram component. If you customize the diagram class, the add/remove functionalities of the diagram’s will not work. So could you please share us more information about your requirement such as using screenshot or video to elaborate your requirement, which will help us validate and provide a better solution? 

Code example: 

//Add a custom connector to symbbol palette... 
private void CreatePaletteConnector(string id) 
{ 
ExampleConnector diagramConnector = new ExampleConnector() 
{ 
Id = id, 
}; 
ConnectorList.Add(diagramConnector); 
} 
 
//Activate tool to draw a custom connector... 
private void Draw(MouseEventArgs args) 
{ 
drawingObject = new ExampleConnector(); 
diagram.Tool = DiagramTools.ContinuousDraw; 
} 
 
public class ExampleConnector : DiagramConnector 
{ 
 
public ExampleConnector() : base() 
{ 
Type = DiagramSegments.Orthogonal; 
SourcePoint = new ConnectorSourcePoint() { X = 0, Y = 0 }; 
TargetPoint = new ConnectorTargetPoint() { X = 100, Y = 100 }; 
Style = new ConnectorShapeStyle() 
{ 
StrokeColor = "#FF0000", 
StrokeWidth = 2, 
}; 
TargetDecorator = new ConnectorTargetDecorator() { Shape = DecoratorShapes.None }; 
Constraints = ConnectorConstraints.Default & ~ConnectorConstraints.Drag; 
} 
} 


Regards,

Hi Naganathan,

Firstly thank you for the reply. 

The continuous draw does seem to follow the defined styles, however drawing from a node port doesn't, apologies I should have been clearer.

STR:

  1. Define a node with a port that has the PortConstraints.Draw set
  2. Add custom styling to a connector instance and set as the drawing object
  3. Drag a connector from the port created above.

P.S. When is the blazor Diagram feature scheduled to come out of preview?
