GroupPanel Context Menu

This sample shows how you can add a custom context menu to a GroupPanel control so users can right-click the markers in the panel to collapse, expand, sort, or remove groups.

Note: To enable drag/drop operations on touch devices, your project should import the '@grapecity/wijmo.touch' module.
