wpf return object from showdialog in csharp

To return an object from the ShowDialog() method in a WPF application, you can create a new window and define a property to hold the return value.

Here's an example:


main.cs
// Create a new window to display dialog
DialogWindow dialogWindow = new DialogWindow();

// Show the dialog and wait for result
bool? result = dialogWindow.ShowDialog();

// Check if user clicked OK button
if (result == true)
{
    // Retrieve the return value from the dialog window
    object returnValue = dialogWindow.ReturnValue;

    // Use the return value
    // ...
}

In DialogWindow class, you can define a property ReturnValue to hold the return value :


main.cs
public partial class DialogWindow : Window
{
    // Define a public property to hold the return value
    public object ReturnValue { get; set; }

    public DialogWindow()
    {
        InitializeComponent();
    }

    private void OkButton_Click(object sender, RoutedEventArgs e)
    {
        // Set the return value and close the dialog
        this.ReturnValue = new object(); // Change this to whatever object you want to return
        this.DialogResult = true;
    }

    private void CancelButton_Click(object sender, RoutedEventArgs e)
    {
        // Close the dialog without setting the return value
        this.DialogResult = false;
    }
}

In this example, the OkButton click event handler sets the ReturnValue property with the desired object and closes the dialog. The CancelButton click event handler cancels the dialog without setting the return value.
