Hi,
I am using WebDataTree with custom context menu not the WebDataMenu. So when I right click on Tree node, I get the custom context menu, but also getting default context menu. See my below JS code for right click on Node. After execute the args.set_cancel = true, the default context menu is being showing.
function nodeClick(tree, args) { var button = 1; if (args.get_browserEvent() != null) { button=parseInt(args.get_browserEvent().button); } //right click if (button == 2) { //call context menu on another page parent.showContextMenu(args); args.set_cancel = true; } }
