When the field is set to ReadOnly=true the set_value not work!

Enabled cannot use because the user needs access to the field to copy the information.
How do I fix this?

Hello Rudá Cunha,

set_value() works when a RadTextBox is readonly, however, you should know that the new value is not persisted across postbacks - this is by design and asp:TextBoxes behave the same way.

<%@ Page Language="C#" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
 
<head runat="server">
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<title>RadControls</title>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
 
<telerik:RadTextBox ID="RadTextBox1" runat="server" ReadOnly="true" Text="initial value" />
 
<asp:Button Text="set new value 1" runat="server" ID="Button1" OnClientClick="return setNewValue(1);" />
 
<asp:Button Text="set new value 2" runat="server" ID="Button2" OnClientClick="return setNewValue(2);" />
 
<asp:Button Text="get value" runat="server" ID="Button3" OnClientClick="return getValue();" />
 
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
 
function setNewValue(nv)
{
    $find("<%= RadTextBox1.ClientID %>").set_value(nv);
    return false;
}
 
function getValue()
{
    alert($find("<%= RadTextBox1.ClientID %>").get_value());
    return false;
}
 
</script>
</telerik:RadCodeBlock>
 
</form>
</body>
</html>
