Clustering with Dynamic Layers

YaminNoor — Fri, 01 Nov 2013 17:39:44 GMT

Hi
I wanted to see if I can use clustering for my dynamic layers. I am using this statement to load 10 sublayers under Data Layers category. All I want is to use clustering for some specific layers using layer ids.

<layer label="Data Layers" type="dynamic" visible="true" alpha="1" url="http://url_here/MapServer"/>

I am guessing I have to use sublayer & clustering tag in combination. But how? If anyone knows, it will be a great help.

Thanks
Yamin

Hi Yamin,

I am not really sure where the Dynmaic Layers support for clustering. But you can start read the sample code:
https://developers.arcgis.com/en/flex/sample-code/clustering.htm

By changing the tag <esri:FeatureLayer> to <esri: DynamicLayer>. I would suggest start from one layer then move to 2 and more sublayers under Data Layers catgory.

For Sublayers information you can reference this thread:

Hope these tips can help. Good Luck!

Yamin,

Clustering can be applied only to feature and GeoRSS layers not dynamic layers. The layer tag you posted up looks like you are referring to the flex viewer not the API. Help on clustering in the viewer can be found here:
