document.GetElementById('ctl00_MainPlaceHolder1_TextBox1') should be document.getElementById('ctl00_MainPlaceHolder1_TextBox1') The getElementById starts with small letter. This might be your problem. use disabled = true / false; Cheers.

i think you should also try document.form1.txt1.readOnly=true; hope this will work for you
