    Here is my code

    <asp:ScriptManager ID="ScriptManager1" runat="server" 
                   LoadScriptsBeforeUI="false"
                   EnablePartialRendering="false" EnableCdn="true">
</asp:ScriptManager>

    I don't understand what I am doing wrong.

    Or is there any possible to add async attribute?

    Any Idea?

    Hi mukul.db,

    I don't understand what I am doing wrong.

    If you could provide some error message or more relevant code, it will be easier for us to help you.

    ScriptManager.EnablePartialRendering Property

    Gets or sets a value that enables partial rendering of a page, which in turn enables you to update regions of the page individually by using UpdatePanel controls.

    ScriptManager.LoadScriptsBeforeUI Property

    Gets or sets a value that indicates whether scripts are loaded before or after markup for the page UI is loaded.

    If you want to use ScriptManager control to enable partial-page rendering, you could refer to the follow code snippets.

    <form id="form1" runat="server">
        <asp:ScriptManager ID="MainScriptManager" runat="server" />
        <asp:UpdatePanel ID="pnlHelloWorld" runat="server">
            <ContentTemplate>
                <asp:Label runat="server" ID="lblHelloWorld" Text="Click the button!" />
                <br />
                <br />
                <asp:Button runat="server" ID="btnHelloWorld" OnClick="btnHelloWorld_Click" Text="Update label!" />
            </ContentTemplate>
        </asp:UpdatePanel>
    </form>

code behind:

protected void btnHelloWorld_Click(object sender, EventArgs e)
{
    lblHelloWorld.Text = "Hello, world - this is a fresh message from ASP.NET AJAX!The time right now is: " +         DateTime.Now.ToLongTimeString();
}

    Best Regards,

    Chris
