    How can I reset a RadTextBox to its configured EmptyMessage value using JavaScript?

    Note, I want to use the property value without having to state it twice.

    Hi Craig,

    Please check the following code I tried to clear the RadTextBox content and display the empty message.

    <telerik:RadTextBox ID="RadTextBox1" runat="server" EmptyMessage="Enter Name">
    <telerik:RadButton ID="RadButton1" runat="server" Text="Clear Textbox" AutoPostBack="false"

    <script type="text/javascript">
        function clearTextbox(sender, args) {
            var radtextbox = $find('<%=RadTextBox1.ClientID %>');

    There is no such direct method to get the RadTextBox collection, but you can try the following approach to meet your scenario:

    function GetRadTextBoxes()
        var allRadTextBoxes = [];
        var allRadControls = $telerik.radControls;
        for (var i = 0; i < allRadControls.length; i++)
            var element = allRadControls[i];
            var isRadTextBox = element instanceof Telerik.Web.UI.RadTextBox;
            if (isRadTextBox)
                Array.add(allRadTextBoxes, element);

    Once you have all textboxes you can clear them.

    The solution is based on How-to create a javascript array of all particular RadControls on the page.
