Multi-functional app

[shuzERR]

Hello, I need to create app with login page and after logging in few features. I want to what is the best way to do this? I used sample code from Example.cs but modified
btnLogin.Clicked += () => { if (usernameText.Text == "admin" && passwordText.Text == "password") { MessageBox.Query ("Logging In", "Login Successful", "Ok"); Application.RequestStop (); } else { MessageBox.ErrorQuery ("Logging In", "Incorrect username or password", "Ok"); } };
to
btnLogin.Clicked += () => { if (usernameText.Text == "admin" && passwordText.Text == "password") { MessageBox.Query("Logging In", "Login Successful", "Ok"); Application.RequestStop(); Application.Run<MainWindow>(); } else { MessageBox.ErrorQuery("Logging In", "Incorrect username or password", "Ok"); } };
but now when I successfully log in, I still recieve MessageBox when clicking
Is that correct way or I should know abaout something else?

Your event handler for btnLogin has 3 statements

MessageBox.Query("Logging In", "Login Successful", "Ok"); 
Application.RequestStop(); 
Application.Run<MainWindow>(); 

but now when I successfully log in, I still recieve MessageBox when clicking

Do you mean that you still recieve the 'Successful' message? If so that is because you have are still invoking that method (MessageBox.Query("Logging In", "Login Successful", "Ok"); ).

If you change your code to the following (remove the red bits from your code, add the green bits) it sounds like you will get what you want:

// When login button is clicked display a message popup
btnLogin.Clicked += () => {
	if (usernameText.Text == "admin" && passwordText.Text == "password") {
-		MessageBox.Query ("Logging In", "Login Successful", "Ok");
		Application.RequestStop ();
+		Application.Run<MainWindow> ();
	} else {
		MessageBox.ErrorQuery ("Logging In", "Incorrect username or password", "Ok");
	}
};
