    Hi @Kurakula, Julia,

    You can add your Script Manager tags just below the <Form> tag of your page. Here is how you can place your Script Manager tag.

    <body> 
<form runat="server"> 
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> 
...
</form> 
</body>

    Best regards,
    Lan Huang
