Is there a way to change the Label property via javascript.

    
            <telerik:RadTextBox Width="300px" ID="txtUrl" runat="server" Label="Url: " 
        
            EmptyMessage="please type url here" InvalidStyleDuration="100" > 
        
            </telerik:RadTextBox>

Depending on what has been selected in a combobox I want to chnage the label from Url: to something else

    
                var txtUrlInputID = $telerik.$("[id$='txtUrl']").attr("id");  
        
                var txtUrlInput = $find(txtUrlInputID);  
        
                txtUrlInput.set_emptyMessage('Please type Email here');  
        
                txtUrlInput.set_value("")  
        
            //I would like to set label as well. I know the below does not exist but can I do it another way.  
        
            //txtUrlInput.set_label("Email: ")

Hi Paul,

You can achieve the desired behavior like this:

<%@ 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">

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

<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" />

<asp:TextBox ID="TextBox1" runat="server" Text="Label" />

<asp:Button ID="Button1" runat="server" Text="Apply" OnClientClick="return setLabel()" />

<br /><br />

<telerik:RadTextBox ID="RadTextBox1" runat="server" Label="Label" />

<script type="text/javascript">

function setLabel()

{

var tb = $find("<%= RadTextBox1.ClientID %>");

$get(tb._wrapperElementID).getElementsByTagName("label")[0].innerHTML = $get("<%= TextBox1.ClientID %>").value;

return false;

}

</script>

</form>

</body>

</html>
