void ClearAllControlsRecursive(Control container)
{
    foreach(var control As Control in container.Controls)
    {
        if(typeof control is TextBox)
        {
            ((TextBox)control).Text = String.Empty;
        }
        if(control.HasControls())
        {
            ClearAllControlsRecursive(control);  
        }
    }
}

then call this method like this:

ClearAllControlsRecursive(yourContainer);

You can also switch on the control type and clear the values accordingly.

foreach(var control As Control in (pnl.HasControls())) {} – Sambasiva Oct 03 '13 at 09:13
Nope, you need to put the for loop in a method, that takes in parameter a container. Then, you can make it recursive. I edited my Answer with an example. – Superzadeh Oct 03 '13 at 09:22
Then you should ask another question on this site about it. But before you do that, make sure you actually try to debug and code it. This is not a "do my homework" site. – Superzadeh Oct 03 '13 at 09:33
Updated the code, Controls is a Property, not a method. Just remove the "()" and it will work ... – Superzadeh Oct 03 '13 at 09:37

you can try like this

foreach (object control in form1.Controls) {
    if (control is TextBox) {
        control.Text = "";
    }
}

you can use this extension method :

public static IEnumerable<TControl> GetChildControls(this Control control) where TControl : Control
    {
        var children = (control.Controls != null) ? control.Controls.OfType<TControl>() : Enumerable.Empty<TControl>();
        return children.SelectMany(c => GetChildControls(c)).Concat(children);
    }

use :

foreach (TextBox tb in this.GetChildControls<TextBox>())
{
    tb.Text = String.Empty;
}

and here is a code(answer the question) for clear all controls on the form.

Another method :

yourForm.Controls.OfType<TextBox>().ToList().ForEach(textBox => textBox.Clear());
