Limitations of Asp.net

After two weeks of ASP, I feel bound to the Asp.net control.

ASP is of course very good, it has a lot of space is very convenient, I need to easily display out. However, these functions seem to be insufficient in the future. To be simple, try to maintain the display function of the control.

Why cannot I easily extend the functions of controls?ProgramPersonnel are generally relatively lazy, especially reluctant to perform large-scale reconstruction. When he finds that the predefined control cannot meet his function, he must fix it.

However, ASP does not have the advantages of visualization, but it is still being modified.CodeASP code is not concise. I feel like I am stuck in the ASP framework.
