Try this

C#

function fnvalidate() {
        if (!form1.TextBox1.value.match(/^[a-zA-Z]+$/) && form1.TextBox1.value != "") {
            form1.TextBox1.value = "";
            form1.TextBox1.focus();
            alert("only alphabets are allowed as UserName");
        }
    }

Call the function in onblur event of ur control on client side
