    Your HTML mark up for RadTextbox is wrong, Usually Telerik controls will have a TagPrefix “telerik”, just like "asp" for asp.net controls.

    Please modify your code like given below

    <asp:ScriptManager ID="ScriptManager1" runat="server">
            <telerik:RadTextBox ID="test" runat="server">

    Side Note : Make sure you have the below tag prefix line in your page.

    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
