Debug it. It sounds like it isn't hitting your controls.

A larger code sample would be helpful however I suspect your having scope issues. What is 'this' referring to in relation to where your code is being executed?

Try this:

C#

private void Button1_Click(object sender, System.EventArgs e)
{
    string allTextBoxValues = "";
    foreach (Control c in Page.Controls)
    {
        foreach (Control childc in c.Controls)
        {
            if (childc is TextBox)
            {
                allTextBoxValues += ((TextBox)childc).Text + ",";
            }
        }
    }
}
