When to call MapView.LocationToScreen()

Question

Hi!

Is there an event/property I can use to determine when functions like LocationToScreen() can be called? I noticed that I have to wait several hundred milliseconds until this function doesn't return (NaN, NaN).

Hi Morten,

thanks. Waiting only for SpatialReference != null doesn't work, but waiting for VisibleArea != null seems to work.

Wait for the VisibleArea or SpatialReference property on the view has been established. You could also wait for the first ViewpointChanged event.
