popup another form?

[avmvldr]

I am pretty new to C# even though I've been developing software for quite some time. I also took about 4.5 years off from IT. Anyway, I'm trying to find a good FREE resource for learning this language. Right now, I'm trying to build a simple little WPF form with input and storing the data to a SQL Server DB.

My problem is, when I click a button, I just want to popup another form. I'm trying to use the following statement:

Form f = new Form();

Below is the code that I have right now.

using System.Windows;

namespace WpfApp1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void AddRecord_Click(object sender, RoutedEventArgs e)
        {
            ///How do I popup a form here
        }
    }
}

Thanks!

WPF uses classes that derive from Window. Windows Forms (aka WinForms) uses classes that derive from Form. I think you are trying to mix WPF and WinForms.

As an aside, you should first focus on learning how to use C# with just plain old console programs. Once you know the language pretty well then start learning the UI framework of your choice. Better to climb on learning curve at a time instead of trying to climb 2-3 learning curves simultaneously.

Anyway, you would do something like:

OtherWindow other = new OtherWindow();
other.Show();

which is similar to WinForms. You don't just all the constructor. You also need to tell it to show itself.

SkyDiver,

Thanks for your reply. I ended up figuring it out which is basically what you did. I'm also doing the C# tutorials on the Microsoft Docs site using the browser as a console...thanks again!

And maybe don't make WPF or WinForms the next thing you learn; they're not so in-demand these days
