    When you have a asp.net textbox control defined in RadInputManager as TextBoxSetting and

    If you disable the textbox control client-side prior to postback, the value is lost on postback.

    Consider the following code:
    <%@ Page Language="C#" %>
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
    <script runat="server">
        protected void btnGo_Click(object sender, EventArgs e)
    <head id="Head1" runat="server">
    <meta http-equiv="content-type" content="text/html;charset=utf-8" />
    <title>RadControls for ASP.NET AJAX</title>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server" />
    <telerik:RadInputManager ID="RadInputManager1" runat="server">
        <telerik:TextBoxSetting BehaviorID="PayeeLine1Behavior" EmptyMessage="Enter Payee / Beneficiary Name Here" ErrorMessage="Payee/Beneficiary Required"
            Validation-IsRequired="true" Validation-ValidationGroup="ValGrpPayeeInfo">
                <telerik:TargetInput ControlID="tbPayeeLine1" />
    <asp:TextBox ID="tbPayeeLine1" name="payee" runat="server" MaxLength="33" Width="300px" />
    <asp:Button ID="btnDisable" runat="server" Text="Disable" OnClientClick="DisableTextBox();return false;"></asp:Button>
    <asp:Button ID="btnGo" runat="server" Text="Go" onclick="btnGo_Click"></asp:Button>
    <script type="text/javascript">
        function DisableTextBox() {
            var tb = $find("<%= RadInputManager1.ClientID %>").get_targetInput("<%= tbPayeeLine1.ClientID %>");
            document.getElementById('<%= tbPayeeLine1.ClientID%>').disabled = true;

    Hi Brian,

    You can observe the same behavior if you use a regular asp textbox when it is not extended with InputManager  - the value is not persisted on postback when the control is disabled.

    Kind regards,
