Example

Designing a user-friendly login screen layout using native WPF components like TextBox, PasswordBox, and Button.

Scenario

A developer needs to create a consistent login screen for their application. MVVM WPF Expert guides them to use a Grid for layout, TextBox for username input, PasswordBox for password input, and Button for login action, resulting in the following XAML: ```xml <Grid> <TextBox x:Name="UsernameTextBox" PlaceholderText="Username" /> <PasswordBox x:Name="PasswordBox" /> <Button x:Name="LoginButton" Content="Login" /> </Grid> ```

Example

Creating a ViewModel for the login screen with properties bound to the TextBox and PasswordBox.

Scenario

MVVM WPF Expert helps the developer create a LoginViewModel class, where Username and Password properties are implemented with INotifyPropertyChanged. The command for the login button is also handled in this class: ```csharp public class LoginViewModel : INotifyPropertyChanged { private string _username; private string _password; public string Username { get { return _username; } set { _username = value; OnPropertyChanged(); } } public string Password { get { return _password; } set { _password = value; OnPropertyChanged(); } } public ICommand LoginCommand { get; } // Constructor and other members... } ```

Example

Binding button clicks to ViewModel commands using ICommand.

Scenario

A developer needs to bind a button click event to a command in the ViewModel. MVVM WPF Expert guides the developer to implement ICommand in the ViewModel and bind it in XAML: ```csharp public class LoginViewModel { public ICommand LoginCommand { get; } public LoginViewModel() { LoginCommand = new RelayCommand(LoginExecute); } private void LoginExecute(object parameter) { // Execute login logic } } ``` ```xml <Button Content="Login" Command="{Binding LoginCommand}" /> ```

Example

Suggesting the use of DataTemplate for displaying a list of user objects.

Scenario

A developer is creating a screen to list user profiles. MVVM WPF Expert suggests using a ListBox with a DataTemplate to customize the display of each user: ```xml <ListBox ItemsSource="{Binding Users}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Name}" /> <TextBlock Text="{Binding Email}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> ```
