Have you tried setting the DisabledHandlesColor property?

I hope that helps,

Hi Stoyan,

I want to display RectangleBorder to select the node but if the node is active item of the diagram than RectangleBorder should have some adorner inside it.

How can I get this?

I have tried this code; please suggest where to need make changes?

Code
Select All
private void diagram_DrawAdjustmentHandles(object sender, MindFusion.Diagramming.Wpf.DrawItemEventArgs e)

  {


if (e.Item is DiagramNode)


{


    ShapeNode node = e.Item as ShapeNode;


    if (node != null)


    {



  double hatchSize = diagram.AdjustmentHandlesSize;



  Pen pen;







  if(node == diagram.ActiveItem)



  {




node.HandlesStyle = HandlesStyle.HatchHandles3;




diagram.DisabledHandlesColor = Brushes.Blue;




diagram.AdjustmentHandlesSize = 5;




pen = new Pen(Brushes.Blue, MindFusion.Diagramming.Wpf.Constants.GetPixel(diagram.MeasureUnit) * 3);






  }



  else



  {




pen = new Pen(Brushes.Blue, MindFusion.Diagramming.Wpf.Constants.GetPixel(diagram.MeasureUnit) * 3);



  }






  Rect nRect = new Rect(0, 0, node.Bounds.Width, node.Bounds.Height);



  e.Graphics.DrawRectangle(null, pen, nRect);



  Keyboard.Focus(diagram);


    }


}

  }



Regards,
Anshul

Hi,

What exactly do you need to draw in the ActiveItem case? Note that if you keep the node.HandlesStyle = HandlesStyle.HatchHandles3 assignment there, you won't get this event raised anymore, unless you revert the style to Custom later.

I want a custom implementation.
For active node. Rectangle selection should also have four/eight adorner while in case of other nodes only Rectangle selection should be there.

Hi Stoyan,

I am sending a sample image to show the behavior of handle on active node which I want in my application.

1). Handle should have rectangle border around it for all other nodes other than active node.

2). For active node, handle style should have rectangle border with some adorner around it.


Regards,
Anshul

You could set HandlesStyle to Custom and handle DrawAdjustmentHandles like this:

Code
Select All
void diagram_DrawAdjustmentHandles(object sender, DrawItemEventArgs e)
{
	var node = e.Item as DiagramNode;
	if (node != null)
	{
		if (node == diagram.ActiveItem)
		{
			node.HandlesStyle = HandlesStyle.HatchHandles3;
			node.DrawHandles(e.Graphics, Brushes.Red);
			node.HandlesStyle = HandlesStyle.Custom;
		}
		else
		{
			node.HandlesStyle = HandlesStyle.MoveOnly;
			node.DrawHandles(e.Graphics, Brushes.Black);
			node.HandlesStyle = HandlesStyle.Custom;
		}
	}
}

Hi stoyan,

Thanks for the code sample. Its working well but need some clearity in selection border. I have set selection border color as DarkBlue but it has some black dots. I have tried with some other color(Red, Yellow etc.) as well but that black dots are always coming. can we remove these black dots?

Code which I have used is

Code
Select All
double hatchSize = diagram.AdjustmentHandlesSize;



  if (node == diagram.ActiveItem)



  {




node.HandlesStyle = HandlesStyle.HatchHandles3;




node.DrawHandles(e.Graphics, Brushes.DarkBlue);




node.HandlesStyle = HandlesStyle.Custom;



  }



  else



  {




node.HandlesStyle = HandlesStyle.MoveOnly;




node.DrawHandles(e.Graphics, Brushes.DarkBlue);




node.HandlesStyle = HandlesStyle.Custom;



  }




  Pen pen = new Pen(Brushes.DarkBlue, MindFusion.Diagramming.Wpf.Constants.GetPixel(diagram.MeasureUnit) * 3);



  Rect nRect = new Rect(0, 0, node.Bounds.Width, node.Bounds.Height);



  if (node.Shape == textOnTheRightRound)




e.Graphics.DrawRoundedRectangle(null, pen, nRect, nRect.Width / 9, nRect.Height / 3);




  else




e.Graphics.DrawRectangle(null, pen, nRect);


Regards,
Anshul

Hi Stoyo,

In case of e.Graphics.DrawRoundedRectangle(null, pen, nRect, nRect.Width / 9, nRect.Height / 3);

I am still getting Rectangular Black Colored Dotted Border along with my DarkBlue RoundRectangle.

How can I remove this RectangularBlackColoredDotted Border?

Regards,
Anshul


A general question: If I want to attach an Image in the Post, how can I do this? I have selected and putted some image path inside it but not able to attach image.

Hi Anshul,

Do not call the built-in node.DrawHandles method if you don't need the standard dotted border. You can't upload images here; you might upload it on flickr.com or your server, paste the URL, select it, and click the "insert image" button from the toolbar above the message field.
