Javascript - Unanswered questions - Part 1

What is Event delegation? Event delegation is Javascript as it relates to the DOM. It basically means that if you attach an event listener to a DOM element that listener is not only firing on that DOM element. It's actually firing on every children in that. So, for instance if you have a navigation and so you've got an unordered list you've got list items and then you've got anchor tags inside that navigation what you have. If you add an event listener to the ul element in essence you're actually adding event listener to all of the children as well. In short, JS event listeners fir not only on a single DOM element but on all its descendants. What is Event Bubbling? It's actually inverse of Event delegation.

Large Volume of Dataset Transfer from WCF to Silverlight

Most of the times the developers, architects have the problem to retrieve large volume of data from WCF Service to Silverlight client applications. It’s a big head ache for developers. But it’s not up to that much problematic one. We can solve this problem by changing some property’s values in Web.config of WCF Service host, Silverlight application’s ServiceReference.clientconfig and Silverlight XAP hosted ASP.Net Applications. Here I’m going to explain the Web.config changes we need to retrieve large volume of data from WCF Service and also uploading large size of files to the Server. Last week, I was trying to figure out why my WCF service call always threw the generic NotFound exception when trying to retrieve large datasets. Even though, I set buffer limits to 2147483647 (int.MaxValue) in the Silverlight ServiceReferences.ClientConfig file and WCF Service configuration Section under web.config the problem was persisting. I tried so many things from Data Access Layer and UI. Finall...
