following code:
protected void Page_Load(object sender, EventArgs e)
{
foreach(Control ctrl in Page.Controls)
{
ListBox1.Items.Add(ctrl.GetType().ToString() + ":" + ctrl.ID);
}
}
This code will access the Page.Controls collection and cycle through it, taking the
type and ID of the control and adding them to the list. You can see the results of the code
in Figure 3-6.
