How to use AddInfo

[Jeff]

Hi, can you give me some guidance on how to use the AddInfo property of nodes?

1. How to add items to AddInfo in MVC/.NET
2. How to retrieve the values in JavaScript

Thanks for your help.

Ooops.  I meant to put this in the ASP.NET MVC forum.  Could you move it for me?  Sorry, and thank you.

Hi, can you give me some guidance on how to use the AddInfo property of nodes? 1.       How to add items to AddInfo in MVC/.NET 2.       How to retrieve the values in JavaScript Thanks for your help.

We have created a simple sample to meet your requirement and attached below. Please see the code snippet below.   //add items to addinfo           Node add = CreateNode("add", 150, 50, 200, 200, "add");             Dictionary<string, object> addInfo = new Dictionary<string, object>();             addInfo.Add("email", "[e-mail]");             add.AddInfo = addInfo;             model.Nodes.Add(add);   function onclick(args) {            var diagram = $("#Diagram1").ejDiagram("instance");            if (args.element.shape) {                //retreiving addinfo values in javascript    var addinfo = args.element.addInfo.email;            alert(addinfo);         }     }

Please let me know if any concerns.

Hi, at least in the present version js args.element.addinfo does not seem to exist. I tried .element.attributes.getNamedItem() but failed. Please advise.

Hi Gyorgy Gorog, 

 

We have created a MVC sample in which we have set an addInfo property for nodes and retrieved it in the client side(.cshtml file) using click event. Please refer to the code example and sample below. 

 

Code example: 

 

DiagramController.cs 

 

  BasicShape node = new BasicShape(); 

   //create addInfo property for node 

   Dictionary<string, object> addInfo = new Dictionary<string, object>(); 

   addInfo.Add("email", "[e-mail]"); 

   node.AddInfo = addInfo; 

   Diagram.Nodes.Add(node); 

 

  //define click event 

  Diagram.Click = "click"; 

 

  function click(args) { 

        if (args.element) { 

            if (args.element.addInfo) { 

                             //retrieve addInfo property 

                alert(args.element.addInfo.email); 

            } 

        } 

    }
