Client OnKeyPress Backspace key

[Dirk]

I am having problems with the client side events. Im trying to fire a javascript whenever a key is pressed:

<script language="javascript" type="text/javascript">

        function tbGroupNamekeypress(sender, eventArgs) {
            var c = eventArgs.get_keyCharacter();
            var idtbGroupname = '<%=tbGroupName.ClientID%>';
            var tbGroupnameValue = encodeURI($('#' + idtbGroupname).val() + c);
            $('#divGroupNamePreview').load("/_layouts/checkGroupName.aspx?name=" + tbGroupnameValue + "&t=" + new Date().getTime());
        }
 </script>

<telerik:RadTextBox runat="server" ID="tbGroupName" Width="79%" Skin="Metro" ClientEvents-OnKeyPress="tbGroupNamekeypress" MaxLength="47"></telerik:RadTextBox>

this works for all keys except the backspace key. Is there any workaround for this?

Hi Frank,

You can handle directly the onkeydown event:

<script......>

function handleKeyDown(inputElement, eventArgs)
{
    var TextBox = $find(inputElement.id);
}

</script>

<telerik:RadTextBox runat="server" ID="tbGroupName" onkeydown = "handleKeyDown(this,event)"></telerik:RadTextBox>
