how to enable Zooming without Editing

[Jacek Garczyk]

Hi,

After upgrade my project to 15.3.0.33 version, zooming of SfDiagram stoped working.

In my code I haved following diagram's constraints:

sfdiagram.Constraints = GraphConstraints.Default  ;

sfdiagram.Constraints &= ~(GraphConstraints.PageEditing | GraphConstraints.PanRails);

sfdiagram.Constraints =  GraphConstraints.Zoomable;

When I comment second code line, zooming is fine, but I'd like to have zoomable without editing. I attached example Organization Chart with adding zoom slider on MainWindow. 

Please let me know how to enable zooming with disable editing,

Best Regards, Jacek.

Hi Jacek, 

 

Thanks for contacting Syncfusion Support. 

 

By default, we have added Zoomable constraints to Diagram. We have restricted Zooming once PageEditing is disabled. This is the behavior. We have understood that your requirement is “to disable Page Editing and enable Zooming” for Diagram. This requirement can be achieved by using the Tool property of SfDiagram. We have provided code example and modified sample to represent this. Please refer to the sample from the below link. 

 

Code example: 

//This Tool helps to Zoom and Pan the Diagram, will disable Page editing 

 

sfdiagram.Tool = Tool.ZoomPan;

Hi Ranjitha

Thank You for your answer. It seems working only for first mouseover event. After moving mouse over diagram control the solution stop working.

Please see my video (attachment). In tenth second I did mouseover.
