Different CSS is applied over the markers when opened in mobile device. Which enlarges the marker elements and the rendered positions appear incorrect.

The temporary fix is to reset the marker elements to their original size and position: 

 @media only screen and (-webkit-min-device-pixel-ratio: 2), only screen and (min-device-pixel-ratio: 2) {
     .k-map span.k-marker{
         width: 28px;
         height: 40px;
         margin: -40px 0 0 -14px;

When the map is set to e.g. Zoom=1 the world map shows as continued sequence of the same layout.

All markers set on the map should appear on all correct places, so that the user could zoom out and pan outside the center view port and still be able to see the markers.

FeatureCollections can have a collection of features in which the GeometryCollection type provides the coordinates of multiple geometries.

The above matter should be fully supported, but in RadMap the geometries in the geometry collection does not render.

Release Q1 2015
The following error occurs after the partial post back:

Error: Sys.InvalidOperationException: Two components with the same id 'RadMap1' can't be added to the application.

You can resolve this by using the RadScriptManager instead of native ScriptManager control.

this is my scenario:

I add the MapMarkers to the markers collection  on Server side.
I bind the marker click event on server side and forward the retrieved values to a hidden input and button:

            // Verbinden des Clicks

            string function = "function(sender) { var title = sender.marker.options.title; " +

                " title = title.substr(0, title.indexOf('-') - 1); document.getElementById('" +

                c_MarkerData.ClientID + "').value = title; document.getElementById('" +

                c_Markerclick.ClientID + "').click(); }";

            c_Mainmap.ClientEvents.OnMarkerClick = function;

<div style="display: none; visibility: hidden">

    <asp:HiddenField runat="server" ID="c_MarkerData" />

    <asp:Button runat="server" ID="c_Markerclick" OnClick="c_Markerclick_Click" />


The title starts with a unique ID of the data entity - i need this id to identify the data row when handling the c_Markerclick_Click event. So i misuse the marker title to forward this.

If the MapMarker would have a Tag attribute or so, i could set that on Server side and retrieve the needed Information in a clean way.

Greetings Jochen

In the Kendo/ASP.Net Map add the option for a legend with distance scale that updates on zoom level.  See attached image for placement and function

When the Map position is not on the top of the page, creating a new marker via the OnClick event argument location, the marker is not correctly positioned.

This feature would be useful when the bound markers are dynamically changing. With such functionality the end-user will be able to automatically examine all bound markers and would not need to pan or zoom.

This is actually a request for the RadMap category, but that option is not listed in the "Category:" dropdownlist on this page for some reason?

The problem -- when a RadMap's marker has its tooltip visible (say, by rolling the mouse over the marker), moving the mouse over the tooltip itself does not prevent the tooltip from disappearing. Instead, when the mouse is rolled over the tooltip, the tooltip will hide itself. 

This should be changed for two reasons: 1) when a user rolls over a tooltip, it means they are interested in the tooltip's content and likely do not want it to close. 2) If you have a link inside the tooltip, it can be impossible to reach it in time before the tooltip closes. 

Lengthening the delay to closing is not a solution to this problem. Nor is enable click-to-open, click-to-close for the tooltip, since requiring clicks to open or close the tooltip is too time-consuming for quick scanning of tooltip (until the desired marker item is found).

Only keeping the tooltip visible when moused-over will resolve this issue. I can think of no reason to let the tooltip close when moused over.

This error is due to missing configuration option for the Bing layer. The settingsUrl property of layer options could be used to fine tune the URL and modify it to request data from SSL enabled URL and resolve the mixed content issue.

To resolve the issue, you can configure this property on the OnInitialize event and the options of the Map, exposed by the arguments:

<telerik:RadMap runat="server" ID="RadMap1">
        <telerik:MapLayer Type="Bing" Key="YOUR BING KEY"></telerik:MapLayer>
    <ClientEvents OnInitialize="OnInitialize" />
<script type="text/javascript">
    function OnInitialize(sender, args) {
        var options = args.get_options();
        options.layers[0]["settingsUrl"] = " imagerySet #?output=json&jsonp=bingTileParams&include=ImageryProviders&s=1&key=#= key #";
