ASP.net How to see the Anchors are used in Page

 All the anchor tags are generated from server side ?

You can use javascript. document.getElementsByTagname("a");

If you wanted to do it in server side,

foreach(Control c in this.Page.Controls)
{
    if c.GetType() =="YOUR TYPE")
   {
        //Add the details in the list box.
   }
}

Hope this helps you.
