    I have a radtextbox that I am updating the text with JavaScript (clientside). The new value shows on the page but if I access the control server side, it shows the old value. This control is not being reloaded server side.

    JavaScript: this will set the new value which shows up on the web page

    document.Form1.txtTotalCharge_text.value = document.Form1.txtHdTotalCharge.value

    If I access txtTotalCharge.text on the server side, the old value shows up. The asp:textbox doesn't have this issue. Can anyone tell me how to fix this.

    In order to set text to RadTextBox client-side, it is needed to access the client object of the textbox and use set_value() method as it is shown below:
    <telerik:RadCodeBlock runat="server" ID="RadCodeBlock1">
          <script type="text/javascript">
              function loaded() {
                  txt = $find("<%= tb1.ClientID %>");

    Additionally, you can set AutoPostBack="true" to access this value server-side.
    <telerik:RadTextBox runat="server" ID="tb1" AutoPostBack="true">
            <ClientEvents OnLoad="loaded" />

    Kind regards,
