This is probably simple but i cant see it in the new documentation.
In the old control we used to clear and add markers on the serverside as follows -
How do we do this now with control 6.0.
I have already used the datasource from a sql server db with control 6.0 for loading points and it works great. But in this case i want to just load a couple of values quickly on the serverside.
NB For any one using datasource, make sure your long and lat DB fields are not in varchar etc format as this got a cast error for me...use float etc
