    Hi Vvamc,

    Try to use onkeyup event to count the number of entered character in the RadTextBox. This event will fire when the key is released. Please take a look into the below sample code snippet to achieve your scenario.

    <telerik:RadTextBox ID="rtxtCharacterLength" runat="server" onkeyup="return checkLength(this);">

    function checkLength(txt) {
        var txtLength;
        if (txt != null) {
            var txtLength;= txt.value.length
