Activating server control event in aspx page

I have a simple c# TextBox server control that I have rendered in aspx page. I like to activate the textBox_TextChanged event and I can not. I like somebody to look at this code and fix this problem. Here it is: Open the solution called "[login to view URL]". make sure [login to view URL] has the break point under protected void bLoaded_TextChanged(object sender, EventArgs e) event. Start the program by clicking F5. Text box is rendred and displayed on the Text Box. Change the content of the page and move the tab bar to leave the Text box Control. I want bLoaded_TextChanged to get activated. I want to activate event on the server control. So the program should go to this line: [login to view URL] = false; I am not sure may be public class AATree : WebControl Is not the right selection. Anyway this event is not working. I am not sure what I am missing. Thanks a lot for your help. I don't need resume or background info. If you fix this for me this means you know server control and differences between server control and user control or custom control. More work will come when this issue is resolved. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
