Loading Markers without loop

#1

Hi


     I want to know that is it possible to load markers (more than 20000)  to a layer without using loop(for,foreach).  The looping consumes more time to load, so can you please provide any work around to load markers without using looping statement .


 


Thanks in Advance

Hi Karunakaran, 
  
 Your question is the same one with this topic: gis.thinkgeo.com/Support/DiscussionForums/tabid/143/aff/12/aft/9592/afv/topic/Default.aspx 
  
 I will reply you there.

Hi Karunakaran,

You can use FeatureSourceMarkerOverlay to display many markers. There’s a data source behind the scenes to provide the data, and you don’t have to loop through each feature to make it show.

Here is the detail about this class.

Here is the WPF HowDoI sample where you can find this function:

Here you can find the sample code of this particular feature (FeatureSourceMarkerOverlay):

But display too many markers (like 20,000 mentioned in the thread) on the map will slow things done a bit anyway. You can have a try and find the balance between the count of the features you want to show and its performance.

Thanks,
Mark
