ArcGISDynamicMapServiceLayer mapServiceLayer = MyMap.Layers[8] as ArcGISDynamicMapServiceLayer;
mapServiceLayer.VisibilityChanged += (s, e) => System.Windows.MessageBox.Show("ok");

and I have a checkbox that respoisble change the layer vsibility.

            <CheckBox Content="ways"
                      IsChecked="{Binding MyMap.Layers[8].Visible, Mode=TwoWay}"/>

the chechbox working and changing the visibility of layer.
But visibility changed event of ArcGISDynamicMapServiceLayer is not firing.


I put a breakpoint and watched that Layer[8] of MyMap has visibilityChanged event and not null.

The VisibilityChanged event occurs when the visibility of the sublayers changed.

When the visibility of the layer changes, the Layer.PropertyChanged event is fired. In your Handler you will have to test that the PropertyName is 'Visible'
