Getting started with userHandles - help

I would like to implement the link userHandle in my application.
I've lifted the code from your DiagramBuilder sample that creates the handle (by the way, you give it a name of Line rather than Link).
I've also added the following 3 statements in my load event:

    // Add the link handle
    createLinkHandle(); // Code lifted directly from the SF DiagramBuilder sample app
    diagram.model.userHandles = userHandles;

My selection change handler looks like this:

    function selectionChangeHandler(args) {
        var handles = diagram.model.userHandles;
        handles[0].visible = true;

When I run the app and select a single node, the handle does not show.
I realize I need to be making a lot more checks in my handler above, but for now I'm just trying to get the link handle working when I click on a node.

I'm obviously missing something.
What would that be?

Thanks in advance.

Hi Jim

Thanks for using Syncfusion products.

Please note that we have made API changes for selector related properties (userHandles, selectorConstraints) in our latest release and these properties  are moved from diagram model to selectedItems. Please refer the below sample and code snippet.

Code snippet:

var userHandles = [];

        $(window).load(function () {

            var diagram = $("#Diagram1").ejDiagram("instance");


            diagram.model.selectedItems.userHandles = userHandles;




We have provided the online UG documentation which represents how to use the “Selector”.

Documentation: http://help.syncfusion.com/ug/js/documents/selector.htm

Please refer the below Release notes link to view the breaking changes that we have made in our latest release

Please let me know if any concerns.
