Hi Friends,

I have created windows application using c# coding. In my application i am using GMap-Control, in Gmap-Control i am plotting lot of Markers based on Latitude and Longitude on map.This control is working fine for limited data. If i go for Large data (More then 2000 records) its getting too slow and system is hanging for plotting Markers. I am using FOR LOOP to plot each marker on the map(Based on Latitude and Longitude for each rows in a data-table). Is there any way to plot markers other than FOR LOOP which makes the plotting of markers on Gmap-Control as fast as possible.

Thank's in Advance

I don't know much about your app and even less about GMap-Control but a for loop is as fast as any code you are going to use. You should use the iterator version of the loop rather than an incrementing index; but this won't make that much difference. Since the work being done is in a UI thread, you can't multi-thread anything.

If there is processing that occurs when getting each record, you can create an array of cached record info that is pre-computed.

One thing you can do to create the appearance of faster display is to break the records into chunks and redisplay the control after adding every 'n' records.
