ASP.NET AJAX Control Toolkit Not for Enterprise Applications

We have been using our own ajax framework till now. Now that Microsoft itself published these controls I thought of checking them out.

The first thing is their much talked about UpdatePanel.

I noticed when some client interaction happens the Panel actually calls the Page_Load event every time. It basically loads the entire page instead of just calling the method which should have been written to be self sufficient. This is like let the server reload the page but the client will get only filtered content.

I have never seen a technology which such a big blunder being accepted so fast.

Its a known fact that the page load is used for load content into the page so if it calls this event it would also get all the datasources even though the ajax function does not deserve it.

This shall never work in an enterprise scenario. I am lost for words as to how these so called experts did not notice this blunder.

I am really lost for words.

For those of you who develop enterprise applications please develop your own frameworks.

Happy programming,
Anton
