How to remove the autocomplete in the RadDatePicker and the RadDateTimePicker?

[Paul Tran]

Hi,

I noticed that there's an autocomplete in the RadDatePicker and RadDateTimePicker controls. It is really easy to reproduce, just delete the year in the date and get out of focus, the control will automatically fill it up with some kind of algorithm. 

Is it possible to turn off this feature?

Thanks,

Paul

Hello Paul,

Unfortunately there is no straightforward way to turn off this functionality. You could override the built-in parsing but I don't recommend that you do this.

<script type="text/javascript">
    Telerik.Web.UI.RadDateInput.prototype.parseDate = function (value, baseDate)
    {
        if (new Date(value) != "NaN")
            return new Date(value);
        this.set_textBoxValue(value);
    }
</script>

I had the samiliar issue. I added overidden parseDate function as suggested, it wouldn't auto correct the input date. However, it won't accept two-digit year like '7/15/10', how do I make it take both 2-digit and 4-digit year?
Second question, assume that an invalid date '13/1/2010' enter, the OnError event invokes, then I change to '1/1/2010' by simply deleting '3'. At this moment, I found that no ValueChanging event is triggered. How to capture the changes when delete key pressed?

It is expected that the control won't convert such dates automatically given the fact that the parsing logic is overridden (which is not supported scenario). You should either implement you own parsing algorithm or leave the default functionality intact.

You could handle the onkeydown or onkeyup events.

<telerik:RadDatePicker runat="server" ID="RadDatePicker1">
    <DateInput onkeydown="myFunction()" />
</telerik:RadDatePicker>
