Recently I have noticed some odd behavior for the MapView.NavigationCompleted Event. I have the following XMAL and code-behind.
<esri:MapView WrapAround=”False” NavigationCompleted=”MapView_NavigationCompleted” … />
private void MapView_NavigationCompleted(object sender, EventArgs e){
System.Diagnostics.Debug.WriteLine(“[{0}] {1}”, DateTime.Now.ToString(“hh:mm:ss.fff”),((MapView)sender).Extent.ToJson());
}
When I look at the Output Window I can see that this event sometimes fires twice rapidly within less than a second. Most of the time it seems to only fire once as expected. I have seen this behavior with rolling the mouse wheel, panning, and using the shift key to zoom into a drawn envelope. The coordinates of the extent for the two that fired within half a second of each other are almost identical but actually differ at the 14th decimal place. Our Spatial Reference is WGS84. I am using these extents in a list and the extra extents are causing problems.
Has anyone else seen this behavior? Does this seem like a minor bug?
Thanks,
