    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());
    <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:
    function handleKeyDown(inputElement, eventArgs)
        var TextBox = $find(;
    <telerik:RadTextBox runat="server" ID="tbGroupName" onkeydown = "handleKeyDown(this,event)"></telerik:RadTextBox>
