Zoom in on double click

[Warnestam]

Hi,

I'm missing the opportunity to zoom in by double clicking on the map. Is there a way to detect a double click in the client?

 

Kind regards

Robert

I am having opposite problem. My map zooms on double-click and i would like to avoid that.

Any suggestions?

Hi David,

You can prevent the zoomStart event if the event is a double click/tap. For example (I'm fairly certain jQuery always sends "doubleTap" but just in case I showed a more robust check in case it may send a dlbclick in some browser):

<script>
    function OnZoomStart(evt) {
        if (evt.originalEvent.type &&
            (
                evt.originalEvent.type.indexOf("double") > -1 ||
                evt.originalEvent.type.indexOf("dbl") > -1)
            ) {
            evt.preventDefault();
        }
    }
</script>
<telerik:RadMap RenderMode="Lightweight" runat="server" ID="RadMap1" Zoom="2" Width="300px" Height="300px">
    <ClientEvents OnZoomStart="OnZoomStart" />
    <CenterSettings Latitude="23" Longitude="10" />
    <LayersCollection>
        <telerik:MapLayer Type="Tile" Subdomains="a,b,c"
            UrlTemplate="https://#= subdomain #.tile.openstreetmap.org/#= zoom #/#= x #/#= y #.png"

    </LayersCollection>
</telerik:RadMap>
