asp.net validator that allows everything but not numbers

Question

Hello!

As I put in the title I need a validator (regular expresion, customvalidator, etc) that allows the user to input everything (lettrs, special characters, spaces) but not numbers.

How can I do that?

Thank you,
Sabrina

No I have a LastName field in my country (Uruguay) a last name can be D'Elia or Del Riego so I have to accept both letters and special characters and spaces between one word and another but not accept that the lastname field is just   (only one space)

I've seen what you send me but I could find something that fits what I want. I want a regex that allows all letters and all special characters incluiding space (this is done with ^[^0-9]+$ ) but now the thing that I can't get to work is that it doesn't allow the user to only enter spaces the textbox has to have at least one letter or special character but not only the space. Can you help me with this? I'm really thankful

or you can use asp:TextBox id=txtbox onkeypress=return isNumberKey(event) runat=server/> function isNumberKey(evt) { var charCode = (evt.which) ? evt.which : event.keyCode; if (charCode != 46 && charCode > 31 && (charCode 57)){ return false; } var x=document.getElementById(txtbox).value; console.log(x); }

Thanks! This works very well but the only problem I have is that it allows that the user inputs only one space. Is there a way to also validate that it has no spaces on the begnin? Thank you very much Sabrina

use below javascript function AllowAlphabet() { if (!txtName.value.match(/^[a-zA-Z @#$%&*.]+$/) && txtName.value != ) { txtName.value = ; txtName.focus(); alert(Please Enter only alphabets in text); } }
