    I have a question.
    Anyone know if there is a difference in performance between a user control and a custom control?

  2. Hi,

    Custom Controls and User Controls have different purposes. You can easily
    distribute your Custom Controls just by distributing the assembly but User
    Controls will always need the ASCX file. Also Custom Controls don't support
    visual development but User Controls do support it.

    So I don't think comparing their performance would be correct in this

    If you tell me more about your purpose, I would like to help you more in

    All the best,

    Hi Coskun,
    thanks for your response. I understand the difference of distrubution and visual studio development of user controls and custom controls. I guess what I was wondering was that if I convert my existing user controls to custom controls, would I gain any performance for that extra work?

    This question has been asked many time and the reponse is --

    Well written user control will execute just as good as an equivalent custom
    control. The end game is to emit HTML so in a sense the user controls should
    be faster but that's not necessarily the case. What you can be sure of is
    that you will not suffer a performance loss using a well designed user

    Hope this helps,
