How do I resize the diagram and scrollbars if BoundaryContraints are off and a node is dragged outside of the current boundaries in any direction?

Hi Truman,

Thanks for your interest in Syncfusion products.

We suggest you to set the Diagram.Model’s ‘SizeToContent’ property to ‘true’ to achieve your requirement. Please refer the below code snippet.

Here is the code:
[C#]
//Indicates whether Model will be sized to its content, but not less than MinimumSize
diagram1.Model.SizeToContent = true;

Here is the Sample:

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

I also set

DiagramWebControl1.Style.Add("overflow", "auto");

to get this working.
