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.

ASPX:

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

JavaScript:

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

Thanks,
Shinu.
