map shared datasource

[Joe]

Does some one have a  code example of a map (or multiple maps) using a shared datasource with the map widget?

Hi Joe,

Here is a simple example illustrating how a single DataSource could be used by multiple Map widgets.

Hi Alexander,

Thank you for the reply and the example.  I see that the example works, but I'm still having issues with the map widget.  I'm calling a webapi controller to get geojson for a map layer.  It works with the html helper, but I want to use the javascript widget.  Please see the attached file that contains javascript, webapi, and sample data.  Would you please see what I'm doing wrong?

Thank you!

Hello again Joe,

I reviewed the attached code snippets and I noticed that the DataSource object is used as and additional data parameter for the Map's DataSource. I would recommend specifying the type of the separate DataSource instance and refer it in the Map's layer options. For example:

var ds = new kendo.data.DataSource({
    type: "geojson",
    transport: {
        read: {
            url: "/api/ReportData/GetMoStateMap",
           ...
        }
    }
});

$("#map2").kendoMap({
    layers: [..
           {
               type: "shape",
               dataSource: ds

           }
    ],
