Best Practice for Display (Near) Real-Time Data

[AdamPfister]

I know everyone has a different setup but are there are any recommended methodologies for displaying real-time (or near real-time) data with v2.0 of the API?  I can't find a specific event on the DynamicMapServiceLayer or FeatureLayer that would "listen" for updates to its own underlying data. Should I be looking @ the Silverlight or Flex API for this type of application?

Any thoughts?

Thanks,
Adam

If you've got a dynamic map service that points to a data source that is constantly updated, you could do something as simple as a using setInterval() to refresh your map service every couple of seconds.  http://help.arcgis.com/en/webapi/javascript/arcgis/help/jsapi_start.htm#jsapi/dynamicmapservicelayer...

It does seem like that's the only way to do this at the moment.

Thanks for the reply.

I can't seem to get this to work, can anyone post a little bit of code that shows how to do this? Also, it seems one could trigger refresh() when the layer's onUpdateStart() event fires. Does that event fire as soon as the data starts to be edited, or am I way off-base on this? Thanks!
