i used the code on master page and content page pageload individually. but it not working. my code is below.. Please tel me where should i place code

You didn't paste the code correctly. You pasted this.

private void LoopButtons(ControlCollection controlCollection)
        {
            foreach (var control in controlCollection)
            {
                if (control is Button)
                {
                    // This is sample code
                    // You get each button here
                    // Do something else here
                    Response.Write(((Button)control).Text);
                }
            }
        }

It should be like this.

private void LoopButtons(ControlCollection controlCollection)
{
    foreach (var control in controlCollection)
    {
        if (control is Button)
        {
            // This is sample code
            // You get each button here
            // Do something else here
            Response.Write(((Button)control).Text);
        }

        if (control.Controls.Count > 0)
        {
            LoopButtons(control.Controls);
        }
    }
}

That piece of code is needed to make it recursive.

An observation: The Page_Load is too fat. you have to refactor it.
