Did those replies help? I see that you posted this in the iPhone and iPad forum so the ASP.Net replies might not help. If not then say so.

Hi Manuel, Untitled Page function lettersOnly(evt) { evt = (evt) ? evt : event; var charCode = (evt.charCode) ? evt.charCode : ((evt.keyCode) ? evt.keyCode : ((evt.which) ? evt.which : 0)); if (charCode > 31 && (charCode 90) && (charCode 122)) { alert("Enter characters only."); return false; } return true; } Thanks

Hi, If you want to show any alert message when enter into the text box then use this. function CharValidation(){ var el=document.getElementById('txtName'); var re=/^[A-z]+$/; if(!re.test(el.value) ) { alert("please enter char only"); } } If you want to restrict to enter into the text box then function AllowAlphabet(e) { isIE = document.all ? 1 : 0 keyEntry = !isIE ? e.which : event.keyCode; if (((keyEntry >= '65') && (keyEntry = '97') && (keyEntry return true; else { return false; } } If it is useful then mark it as "Correct Answer"
