Schema Connections in Kendo Diagram

I am currently experimenting with the Telerik Kendo diagram in an attempt to create a visual representation. Due to the fact that I am retrieving all shapes and their connections from my database, I encountered an issue where the attributes of my data source object do not align with the required naming conventions. To address this challenge, I utilized the "schema" for the shapes, which can be observed in the screenshot provided:

While this approach proved effective for the shapes, I attempted to apply the same methodology to the connections without success. Upon conducting further investigation, I came across alternative solutions that do not involve using schema at all.

Is there a method to incorporate schema for the connections as well?

Answer №1

The documentation provided by Telerik explains that the 'from' and 'to' fields in the connectionsDataSource should correspond to the 'id' of the dataSource. Have you experimented with implementing a custom schema.parse function? This function can be used to manipulate the response data before it is utilized, offering a way to map the fields accordingly - see this helpful example.

  var connDS = new kendo.data.DataSource({
    transport:{
        read:{
          url:"https://run.mocky.io/v3/8930bf8f-3bf0-422c-ba93-36a0662338f0"
      }
    },
    schema: {
      parse: function(response) {
        var data = [];
        for (var i = 0; i < response.length; i++) {
          var itm = {
            from: response[i].source,
            to: response[i].destination,
            label: response[i].label
          };
          data.push(itm);
        }
        return data;
      }
    }
  });
