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"

"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

protected void btnGo_Click(object sender, EventArgs e)

{

Response.Write(tbPayeeLine1.Text);

}

</script>

<html xmlns="http://www.w3.org/1999/xhtml" >

<head id="Head1" runat="server">

<meta http-equiv="content-type" content="text/html;charset=utf-8" />

<title>RadControls for ASP.NET AJAX</title>

</head>

<body>

<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">

<TargetControls>

<telerik:TargetInput ControlID="tbPayeeLine1" />

</TargetControls>

</telerik:TextBoxSetting>

</telerik:RadInputManager>

<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() {

debugger;

var tb = $find("<%= RadInputManager1.ClientID %>").get_targetInput("<%= tbPayeeLine1.ClientID %>");

//tb.disable()

alert(tb.get_value());

document.getElementById('<%= tbPayeeLine1.ClientID%>').disabled = true;

}

</script>

</form>

</body>

</html>
