Iterate for loop after user input

Question

for (int i = 0; i < service.journeys.Count; i++)
{
    var popup = new JourneyPopup();

    // Fill out the form
    popup.txtJourney.Text = service.journeys[i].journeyCode;
    popup.txtDays.Text = service.journeys[i].daysOfWeek;
    popup.txtDeparture.Text = service.journeys[i].departureTime;
    popup.txtOrigin.Text = service.journeys[i].description;

    popup.Show();
}

Inside my JourneyPopup form I have a button called 'done'. I need to iterate the for loop only after 'done' has been clicked. How can I do this?

@DROPtableusers Sure, but how do I pause the for loop whilst it waits for the click event? — jskidd3

You might try the .ShowDialog() function. It will not return until the dialog/form has closed.

I assume that it's a WinForm application and JourneyPopup is derived from Form. Then, in the Forms designer, you can give the button a custom int value, that will be returned by the Form.Show() methods when the button was pressed.

At the end of your loop, you then can check this:

if (popup.ShowDialog() != <Returnvalue from button>)
{
    break;
}

Are you assuming WinForms or WPF? The function exists in both, but has different return values.

WinForms. Didn't even know that the Show() method(s) also exist in WPF.
