I am working on an update to the ContactWebContextBrowser control where it would only fetch the web site pages if visible (this way, If you have 15 or more web site tabs on your layouts it is not trying to load all of them when switching contacts). Anyway, the solution was rather simple, and that was largely because the TabControl already sets the visible property of any controls not shown to false. So, all I had to do was to make sure I do not fetch the URL unless it is visible. I also had to add an event handler to make sure that the URL is fetched if the user makes the control visible (presumably by selecting the Tab).
Anyway, thought I'd share the changes, as it will be a few more days before I can post an update, since I had feedback that some users like it the way it is, so I will have to add this "fetch only on visible" feature as n option rather than the only way.
Hope this helps
private void GetURL()
// only fetch the URL if the control (this) is visible
if (this.Visible == true)
if (currentContact != null)
// build the URL to navigate to
// navigate to that URL
// make sure we call GetURL if the visibility of the control is changed. Note, since we are overriding this internal protected method
// we do not have to explicitly do any event hooking.
// also note that we call the base handler to make sure other handlers listening to the event are called.
protected override void OnVisibleChanged(EventArgs e)
