Question

Hi,

I have insert this a public void called SetUser() on master page

    public void SetUser()
    {
       Page.User.Identity.Name.ToLower();
    }

I need call the SetUser() from content page Method (static WebMethod)

I've tried in this mode, but on VS 2019 debug the error

"an object reference is required for the non-static field, method or property..."

Please can you help me?

my code below

[WebMethod(EnableSession = true)]
[ScriptMethod]
public static void Savepnauttlc(pnauttlcweb teleco)
{
    HttpContext.Current.Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
    HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
    HttpContext.Current.Response.Cache.SetNoStore();

    ((Mp)Master).SetUser();
}

It is not possible to call a master page method from a static web method.  This is a fundamental concept to understand in C#.  Basically the master page does not exist during the web request.  Only the web method is called.

Use JavaScript/jQuery to update the current page HTML.
