Hi Laura,
Requirement: “Need to multi-touch gestures, pinch zoom and panning with touch”.
We have a support to achieve your requirement in our SfDiagram Control. We have created a simple sample and video to represent this. Please refer to sample and video link as below.
Sample Details:
In sample, we have used different buttons to Enable/Disable ZoomPan and MultiSelect for the Diagram. ZoomPan is used to Pan/Zoom the Diagraming Objects and the MultipleSelect is used to select multiple Nodes and Connectors
Note:
For more details about Diagraming Tool, please refer the Online Documentation from the below link.
Regards,
