Introduction
One of the new features being added to version 4.0 of ASP.NET is the ability to control the client side IDs that are generated by the framework. Previously the framework would modify the client side IDs to uniquely identify each control. This some times left you with the ID you defined in markup or sometimes left you with something that looks like this, “ctl00_MasterPageBody_ctl01_Textbox1.”
The Problem
The modification of the client side id property works great to ensure that each element is uniquely identified, however, to anyone that has tried to do any sort of client side scripting this becomes very frustrating....
