hide the page border on a diagram?

[Johnathan Tunnicliffe]

Is there a way to hide the page border in my diagram? I'm trying to give the illusion of infinite space but can't get rid of the page border (see screen in attachment).

I've tried the following:

this.diagram1.View.PageBorderStyle.BorderColor = Color.Transparent;
this.diagram1.View.PageBorderStyle.ShowBorder = false;
this.diagram1.View.PageBorderStyle.BorderWeight = BorderWeight.Thick;

But that seemed to have no effect.

Thanks for the help,
John

Hi Johnathan,

Thanks for your interest in Syncfusion products.

We suggest you to set the Diagram.Model.LineStyle’s ‘LineWidth’ to ‘0’ to achieve your requirement.

Here is the code:
[C#]
this.diagram1.Model.LineStyle.LineWidth = 0;

For your convenience we have created a simple sample to achieve your requirement.

Thanks very much, that works great.

I have one more question (slightly unrelated to this one):
What's the way to get the bounds of the current view in the document? Idea would be to ensure that anytime a new node was added, it gets created in center of the page wherever the user happens to be looking in the document.

Thanks very much

Hi Johnathan,

Thanks for the update.

We suggest you to use the Diagram.Model’s ‘DocumentSize’ property to get the current document size of the diagram.

Here is the code:
[C#]
PageSize ModelSz = diagram1.Model.DocumentSize;
Syncfusion.Windows.Forms.Diagram.Rectangle rect = new Syncfusion.Windows.Forms.Diagram.Rectangle(ModelSz.Width/2,ModelSz.Height/2,50,50);
rect.PinPoint = new PointF(ModelSz.Width / 2, ModelSz.Height / 2);
this.diagram1.Model.AppendChild(rect);

For your convenience we have created a simple sample to achieve your requirement.

What I was asking for is if I was zoomed into a section of the document (imagine a giant document), I want to calculate the middle of the view i'm currently looking.

So if i have a giant document and I can only see the bottom right corner of the document and I add a node, I want it to be added in the center of the screen I'm looking at.

Hi Johnathan,

Thanks for the update.

We suggest you to convert Diagram.view’s ‘Clientsize’ to model co-ordinates to achieve your requirement.

Here is the code snippet:
System.Drawing.Rectangle rg = diagram1.Controller.ConvertToModelCoordinates(diagram1.View.ClientRectangle);
Syncfusion.Windows.Forms.Diagram.Rectangle rect = new Syncfusion.Windows.Forms.Diagram.Rectangle(rg.Width / 2, rg.Height / 2, 50, 50);
rect.PinPoint = new PointF(rg.Width / 2, rg.Height / 2);
this.diagram1.Model.AppendChild(rect);

Please try the below sample and let us know if you have any queries.
