how to create an interactive form in c#

Answer 1

Hi,@ Len G. Welcome to Microsoft Q&A. To create a display form and an interactive form in C# WPF (Windows Presentation Foundation), you'll typically use XAML for designing the user interface and C# for handling the logic and interaction. Here are examples of both a display form and an interactive form in WPF. Display Form: A display form is used to show information without allowing users to edit it. It typically contains labels, text blocks, or other controls to display data. Window1(DisplayWindow):

<Grid>
    <Label Content="Name:" VerticalAlignment="Center" HorizontalAlignment="Left" Margin="10"/>
    <TextBlock Text="{Binding UserName}" VerticalAlignment="Center" HorizontalAlignment="Left" Margin="70,0,0,0"/>
</Grid>

   public partial class Window1 : Window
   {
       public Window1(string userName)
       {
           InitializeComponent();
           DataContext = new DisplayViewModel(userName);
       }
   }
   public class DisplayViewModel
   {
       public string UserName { get; }
       public DisplayViewModel(string userName)
       {
           UserName = userName;
       }
   }

Interactive Form: An interactive form allows users to input or edit data. It typically contains text boxes, combo boxes, buttons, etc., to facilitate user interaction. MainWindow:

 <Grid>
      <Label Content="Name:" VerticalAlignment="Center" HorizontalAlignment="Left" Margin="10"/>
      <TextBox Text="{Binding UserName}" VerticalAlignment="Center" HorizontalAlignment="Left" Width="100" Margin="70,0,0,0"/>
      <Button Content="Submit" Click="SubmitButton_Click" VerticalAlignment="Center" HorizontalAlignment="Center" Margin="0,30,0,0"/>
     
   
  </Grid>

 public partial class MainWindow : Window
 {
     public MainWindow()
     {
         InitializeComponent();
         DataContext = new InteractiveViewModel(); // Assign view model to provide data and handle interaction
     }
     private void SubmitButton_Click(object sender, RoutedEventArgs e)
     {
         string userName = ((InteractiveViewModel)DataContext).UserName;
         Window1 displayWindow = new Window1(userName);
         displayWindow.Show();
     }
 }
 public class InteractiveViewModel : INotifyPropertyChanged
 {
     private string _userName;
     public string UserName
     {
         get => _userName;
         set
         {
             _userName = value;
             OnPropertyChanged(nameof(UserName));
         }
     }
     // Add more properties for other data fields
     public event PropertyChangedEventHandler PropertyChanged;
     protected virtual void OnPropertyChanged(string propertyName)
     {
         PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
     }
 }
