hello dears
i have multipe layer and i want when user click on the map get nearest feature and display it
we know method :
QueryTools.GetFeaturesNearestTo
in some cases (large data) takes times to finish but code after that run without wait, for example i open layer
call this method and then close layer
here i got exception that reader must be open or closed , etc thats belong to method is in action but layer will be close immediatly !
i don't know what should i do? is there any built in event that show me the method done its job and continue? or something else?
best regards
