[mapguide-users] Re: Creating and adding layers

[Kenneth Skovhede]

What is the "table of content" ?

Make sure you set "layer.Visible = true"
Make sure your layer is on top (IIRC, Layers.Add() places it at the bottom).
You need to call map.refresh() in javascript for the changes to appear.
I vaguely recall some issue with the legend not refreshing correctly.
