GoogleMap Control 4.1 beta released

I just released GoogleMap Control 4.1 beta.
Get it from codeplex, and give it a try.

Release Notes

In this release were fixed some important issues like: large number of markers using geocoding, zoom end event cycling etc.
Some new features were implemented as well, check out the list below.
I would like to highlight the proper implementation of Marker Manager coming in this release.
Check out the list of changes connected with that feature below.

Issues

• Large number of markers using geocoding
  • Issue with creating large number of Markers
  • Subsequent markers don't show after unsuccessful geocode
  • Random missing markers when using address property and adding more than 10?
• ZoomEnd event subscribing problems
  • OnZoomEnd issue

Features

• MarkerManager - MarkerManager is used to manage visibility of hundreds of markers on a map, based on the map's current viewport and zoom level.
  • The GoogleMaps API GMarkerManager class is deprecated and I have used the recommended open sourced MarkerManager instead.
  • I have added a new inner property MarkerManagerOptions in order to manager the options for the marker manager.
  • GoogleMarker class was changed and couple of new properties were added to it to: MaxZoom and MinZoom.
  • A sample page was added to Samples Website under /marker/MarkerManager.aspx. Check the sample page online here
  • Check out the short demo video (coming soon)
• Map
  • Enterprise / Premier support
• Directions
  • Add 'preserveViewport' functionality
• Polygon
  • Polygon EnableDrawing & EnableEditing

Changes

• The Anonymous JS classes' functions were changed to Pseudo-Named functions for better JS debug and error feedback experience.
• Samples Websites for .NET 2.0 and VB were removed - Sorry, guys, I just have no enough time to support and keep them up to date.

GoogleMap Control JS with Pseudo-Named functions now

I’m working recently on next release of GoogleMap Control v4.1.
As I have mentioned - I’m switching from anonymous to pseudo-named JS function for that release.
All the effort made, was for a better JS debug and error feedback experience.

At least, that’s the theory.
However, today I did some work on the control again and had a chance in practice to prove I was right.
I got some JS error during  my work, but the information I have now in the call stack is much more useful than just a list of anonymous function.

Here is a simple example of what I mean:

In this particular case, I just mismatch the functions’ bodies , but you get the idea, right.

Generic extension method for a safe item value fetch from HttpSessionState.

Hi there,

Here is an extension method for getting a value from the session in a safe manner.

   1: static public bool TryGet<T>(this HttpSessionState session, string key, out T value) {

   2:  

   3:     bool flag = false;

   4:     value = default(T);

   5:  

   6:     if (session != null) {

   7:         object objectValue = session[key];

   8:         if (flag = (objectValue != null && objectValue is T)) value = (T)objectValue;

   9:     }

  10:  

  11:     return flag;

  12: }

   1: bool flag;

   2: if(this.Page.Session.TryGet<bool>("MyFlag", out flag)) {

   3:     // TODO value exists and can be used

   4: }

Regards
