I’d like to handle a code when user start to draw a shape/polygon/line/point/etc…  
But i just don’t know what event should be handled.  
I don’t know if it is related to `map.events.register("WHAT EVENT SHOULD BE APPLIED HERE", this, function (e) {...});`  
or not.

Hi Reza,

Our client side APIs and event can be found here: [Client API Documentation for Map Suite Web Edition](https://community.thinkgeo.com/t/client-api-documentation-for-map-suite-web-edition/4771/23)

It looks you should want to hang the OpenLayers event, but it looks the Openlayers only have an event named featureAdded which can be fired when a feature is added into map, you can view the document here: [http://dev.openlayers.org/docs/files/OpenLayers/Control/DrawFeature-js.html#OpenLayers.Control.DrawFeature.events](http://dev.openlayers.org/docs/files/OpenLayers/Control/DrawFeature-js.html#OpenLayers.Control.DrawFeature.events)

Regards,

Don
