Thanks for using Syncfusion products.
Currently we don’t have support to update diagram’s model width and height at runtime. We consider this as an issue andlogged “Need to update diagram’s model width and height at runtime”as a defect and created a new incident 134564 on behalf of you related to this forum. We suggest you to follow up the incident for further reference using your direct trac account. However you can update the model’s width and height using the “updateViewPort()” API at runtime. We have created a workaround sample which meets your requirement and it is available in the below link for download.
