Hi,
I am trying to impliment a Marker Highlight Layer that changes with user input. ( I have added check boxes to alow the user to check to see data from a dynamic sql statement. This data is loaded into a InmemoryMarkerOverlay and loads correclty on inital load however it does not update to display the new resultset when changed.
How do i properly update an InmemoryMarkerOverlay to show the newly retrieved data or should this be a diferent Overlay type?
Thanks in advance.
Trevor,
The simplest way to update the features in the InMemoryMarkerOverlay is to clear all the features and re-add the new features. If there is only few features are be updated, you can edit them directly by:inMemoryMarkerOverlay.FeatureSource.UpdateFeature(newFeature);
We have an online sample which shows clear and re-add marker to update it. Although it has only one marker but I think it makes sense.

If you have any questions please let me know.
Thanks,
Howard
