"Gimme code" is not a question or a problem. What is it that you have tried to solve your own problem? Where is the code that demonstrates your problem? What is the problem with your code?

see something like this

bool emptyFound = false;
            foreach (Control c in this.Controls)
            {
                if (c.GetType() == typeof(TextBox))
                {
                    if ((c as TextBox).Text == "")
                    {
                        emptyFound = true;
                        error.SetError(c, "Valid input required");
                    }
                    else
                    {
                        error.SetError(c, "");
                    }
                }
            }
                return emptyFound;

C#

this.textBox1.Validating += new System.ComponentModel.CancelEventHandler(this.textBox_Validating);
this.textBox2.Validating += new System.ComponentModel.CancelEventHandler(this.textBox_Validating);
this.textBox3.Validating += new System.ComponentModel.CancelEventHandler(this.textBox_Validating);

// And so on for the 20 boxes.
private void textBox_Validating(object sender, CancelEventArgs e)
{
    TextBox textbox = (TextBox)sender;

    // Do whatever yo need to do with textbox here.
}
