RadDateInput set_newValue in IE7

[Eric]

I have this code to allow users to enter dates into a RadDateInput using the formats mdyy or mddyy, reformatting them as mm/dd/yyyy.  It works great for Firefox and IE8, but it does not work for IE7.  I walked through the code, and set_newValue is in fact fired, but it does not change the date, and it handles those formats as invalid.

I also tried hacking it by setting the textbox and hidden fields directly, but that failed in pretty short order.

Has anyone implemented set_newValue in IE7?

<script type="text/javascript">
    function PreParseDate(sender, eventArgs)
    {
        var reSpace = /\s*/g;
        var reMdyy = /^\d{4}$/;
        var reMddyy = /^\d{5}$/;
        var val = eventArgs.get_newValue().replace(reSpace, '');

        if (reMdyy.test(val))
        {
            eventArgs.set_newValue('0' + val[0] +
     '/0' + val[1] +
     '/' + (val[2] > 1 ? '19' : '20') + val[2] + val[3]);
        }
        else if (reMddyy.test(val))
        {
            eventArgs.set_newValue('0' + val[0] +
     '/' + val[1] + val[2] +
     '/' + (val[3] > 1 ? '19' : '20') + val[3] + val[4]);
        }
    }
</script>
<telerik:RadDateInput ID="rdiDOB" runat="server">
    <ClientEvents OnValueChanging="PreParseDate" />
</telerik:RadDateInput>

Thank you,

Hi Eric,

The problem is not related to our control and is caused by the way different IE versions interpret the javascript code you are using. In the older IE7 val[0] returns "undefined". You can verify this with this simple script:

function pageLoad()
{
    var num = "123456";
    alert(num[0]);
    alert(num[5]);
}

You can workaround the problem by using the charAt() method of the javascript string object:

else if (reMddyy.test(val))
{
    eventArgs.set_newValue('0' + val.charAt(0) +
    '/' + val.charAt(1) + val.charAt(2) +
    '/' + (val.charAt(3) > 1 ? '19' : '20') + val.charAt(3) + val.charAt(4));
}

Yes, that was it.  Thank you, Pavel.
