Secondly if user directly enter http://localhost:1560/Default.aspx in URL user should be redirected to Login Page .

<system.web>
    <authentication mode="Forms">
      <forms loginUrl="login.aspx" 	protection="All" 	timeout="1440" />
		</authentication> 

    <authorization>
      <deny users="?" /> 
    </authorization>
    
    <compilation debug="true" targetFramework="4.6"/>
    <httpRuntime targetFramework="4.6"/>
  </system.web>
  <location path="Login.aspx">
    <system.web>
      <authorization>
        <allow users="*"/>
      </authorization>
    </system.web>

int id;
            BAL.UsrLogin __objectdata = new BAL.UsrLogin();
            id = __objectdata.chkLogin(usercode, pwd);
            if (id == 1)

You should be addin the 'DefaultUrl' property to the 'forms' tag:

<forms loginUrl="login.aspx" defaultUrl="default.aspx" protection="All" timeout="1440" />

and you dont need the 'Location' tag that you're using to allow access to the login.aspx page, since it was declared on the forms.authentication.

also, after using the webmethod to check if the user/password pair is valid, you should call the following code:

FormsAuthentication.RedirectFromLoginPage(TheUsersNameGoesHere, True)

This latest line will ensure that the authentication is done, and that the user gets redirected to the default page once its authenticated

Your question is unclear.  Are you having an issue?  What are the steps to reproduce the issues, what are the expected outcomes and what actually happens?

<system.web>
    <authentication mode="Forms">
      <forms loginUrl="login.aspx" 	protection="All" 	timeout="1440" />
		</authentication> 

    <authorization>
      <deny users="?" /> 
    </authorization>
    
    <compilation debug="true" targetFramework="4.6"/>
    <httpRuntime targetFramework="4.6"/>
  </system.web>
  <location path="Login.aspx">
    <system.web>
      <authorization>
        <allow users="*"/>
      </authorization>
    </system.web>
  </location>

$.ajax({
                        type: "POST",
                        url: "Login.aspx/chkLogin",
                        data: "{'usercode':'" + usercode + "', 'pwd': '" + pwd + "'}",

                        success: function (response)
                        {
                            switch (response.d) {
                                case 1:
                                    window.location.href = "Default.aspx";
                                    break;
                                default:
                                    alert(response.d);
                            }
                        },
                        error: function (XMLHttpRequest, textStatus, errorThrown) {
                            alert("Status: " + textStatus); alert("Error: " + XMLHttpRequest.responseText);
                        }
                    });

public static int chkLogin(string usercode, string pwd)
        {
            int id;
            BAL.UsrLogin __objectdata = new BAL.UsrLogin();
            id = __objectdata.chkLogin(usercode, pwd);
            return id;
        }

<forms loginUrl="login.aspx" protection="All" timeout="1440" />

Add  defaultUrl="Default.aspx" and try removing both the location tag (just insert location tags for the folders where you store images that show on the page and also the CSS and JS files) and the AJAX method, and do the post via VB/C# and check if it works

That is odd... i usualy work in VB, so maybe you need to use 1 instead of true in c# in this context...
