    Default Controls

    Hi all

    I make a control and put it on the form. My control search on the page
    something and if it doesn't found must add one control on the form. I try
    myCotnrol.Page.Controls.Add(c) and I get error "A control cannot modify its
    parents' control collections.". How can I add a control to form from my
    control?

    go to the bottom of the page. there's a section on how to add controls at
    runtime. i'm a newbie, though, and not sure if this is what you need.

    Hi, first remove the control from its parent controls collection them add it
    to the form controls.
    ad-hoc slice of code :
    c.Parent.Controls.Remove(c);
    myCotnrol.Page.Controls.Add(c);
    HTH,r.
