Shapefile over 500 records

Nov 5, 2009 at 2:19 AM

Hi, i'm using this library to add a local shapefile to my silverlight app but when the shapefile has many records the ESRI API takes a lot of time to render the grapchiclayer.

 

any idea to improve the performance for rendering?

I think than using a DynamicLayer instead of a GrapchicLayer increase the performance but i'm not sure on how to create the image that the dynamiclayer returns, any suggestions?

I noticed that performance went down with large datasets.  However, I don't believe it is a drawing issue.  I believe it is purely a memory issue.  Take a look at task manager, and you will notice iexplore growing in memory usage.  My experience is that silverlight apps start to bog down if they consume too much memory.  I don't have anything definitive on this, but that has been my experience.

Thanks aullman,

I'm totally agree with you, the problem is the memory usage. 

I think a graphiclayer demands more memory than a dynamiclayer that's why im trying to implement this, but im still looking for some help.

If I get something ,i'll be posting it.
