Hi @Ruwan Ratnayake ,
You can study this document, which contains detailed steps to implement asynchronous web forms.
https://learn.microsoft.com/en-us/aspnet/web-forms/overview/performance-and-caching/using-asynchronous-methods-in-aspnet-45#CreatingAsynchGizmos
ASP.NET asynchronous pages must include the Page directive with the Async attribute set to "true".
I wrote a simple example, you can refer to:
]1

private async Task GetGizmosSvcAsync()  
        {  
            Label1.Text = "Test";  
        }  

        protected void Button1_Click(object sender, EventArgs e)  
        {  
            RegisterAsyncTask(new PageAsyncTask(GetGizmosSvcAsync));  
        }  

Best regards,
Lan Huang
