Hello, Lee,

Currently, the Kendo UI Map does not have a render/dataBound event like the Kendo UI Chart.

I have now converted this to a Feature request here so people can upvote it and added a vote on your behalf as well. Meanwhile, you could simulate the event in the following way:

• add a change event handler to the marker dataSource and check how many markers are in the response
• add a markerCreated event handler to the Kendo UI Map and increase the count of a variable until it reaches the response length from the previous step

var markersToRender = 0;
var allMarkersRendered = 0;

// marker data source change event handler
change: function(e){
   markersToRender = e.items.length;
}

// map markerCreated event handler
 markerCreated: function(e){
   allMarkersRendered +=1;
   if(markersToRender === allMarkersRendered){
     this.element.css({ opacity: 1 });
   }
}

Here is a runnable example for your reference:

Let me know what you think.
