This user is not accepting anybody's answer and creating new thread of the same question rather discussing with the same thread.



Thanks

in page load section apply this code:


  refid.ReadOnly=true;

refid is that textbox id, change into your textbox id.

If this post helps you mark it as answer



Thanks

Try


private void textBox1_TextChanged(object sender, EventArgs e)
        {
            if (textBox1.Text.Length > 0)
            {
                MessageBox.Show("Do not allow anything numbers,characters and special characters and symbols etc.");
            }
            textBox1.Text = "";
        }
