You need to call JavaScript function on OnBlur() event of textbox
like e.g. your string is: 01/Name-Address

<asp:textbox id="txtAutoComplete" runat="server" onblur="return validateAutoComplete(this);" tabindex="3" xmlns:asp="#unknown"></asp:textbox>

function validateAutoComplete(el) {
    var str = el.value
    var n = str.indexOf("/");
    var l = str.indexOf("-");
    if (n == -1 || l == -1) {
        el.value = "";
    else {
        return true;
