Runtime map edit/update #27

Open vergo77 opened 2 years ago

vergo77 commented 2 years ago

Hello all, I'm working on a GPS based runtime data collector, now I'm able to create a stream for my shape files. My next goal is to update runtime one or more records of this stream without destroy and recreate it every time (SfMap.RemoveShapeFile and SfMap.AddShapeFile), because this happens more times and it causes a flash on GUI. I would to do somthing similar to SFMap.SetRecordVisibility, to change, in my case, the inner color of a rectangle. Is it possible to do it? Thanks. Rob.

Hi Rob, If you're loading a shapefile onto the map you can't edit it once it is loaded and will need to remove it and replace it with an updated shapefile.

If you have a large background shapefile, to avoid the flickering on the GUI you can add/remove your dynamic shapefile as a foreground layer. The EGIS Code Snippets demo on the project's website shows how to do this. https://www.easygisdotnet.com/code-examples.html
