Question

asp.net page is also a control.
how can I access child control within page control?

this.page.?

Answer 1

You can access it via the Controls Collection

Page.Controls

Recursive FindControls from Rick Strahl’s Blog

public static Control FindControlRecursive(Control Root, string Id)
{
    if (Root.ID == Id)
        return Root;

    foreach (Control Ctl in Root.Controls)
    {
        Control FoundCtl = FindControlRecursive(Ctl, Id);
        if (FoundCtl != null)
            return FoundCtl;
    }

    return null;
}

Be careful with this however… This is not a method you want to be using inside a loop or anything.
