Unable to prevent event propagation with OnKeyPress

[Thomas]

 I'm trying to add JavaScript to allow users to select today's date by pressing "T" key.  I've copied the following code from elsewhere in this forum.  Sorry, I cannot find original post.   The below code does exactly what what we want except the t is showing up in the text.  For example, "8/4/2015t" is what is being displayed.  

 Is there a way to prevent key press from being propagated?  Below is demo code that I'm working with.

<telerik:RadDatePicker ID="DatePicker1" runat="server" >
     <DateInput ClientEvents-OnKeyPress="DateTextBoxKeyPress"/>
</telerik:RadDatePicker>

 

function DateTextBoxKeyPress(sender, args) {

    var s1 = args.get_keyCharacter().toUpperCase();

    if (s1 === "T") {

        var datePicker = sender;
        var date = new Date();

        date.setDate(date.getDate());
        datePicker.set_selectedDate(date);
    }
}

Hello Thomas,

You can achieve this requirement by adding args.set_cancel(true); to the end of the function.
That should do the trick. Please give it a try and let me know if it works for you.
