When I click on maximizebtn_Click and the form is maximized then loadbtn_Click doesn't click

What I have tried:

private void maximizebtn_Click(object sender, RoutedEventArgs e)
            // Set the window state to maximized
            if (WindowState == System.Windows.WindowState.Normal)
                WindowState = System.Windows.WindowState.Maximized;
                WindowState = System.Windows.WindowState.Normal;
private void loadbtn_Click(object sender, RoutedEventArgs e)
        // Create OpenFileDialog
        Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();

        // Set filter for file extension and default file extension
        dlg.DefaultExt = ".stl";
        dlg.Filter = "STL Files|*.stl;";

        // Display OpenFileDialog by calling ShowDialog method
        Nullable<bool> result = dlg.ShowDialog();

        if (result == true)
            // Open document
            string filename = dlg.FileName;
            openfile = filename;
        ModelVisual3D device3D = new ModelVisual3D();
        device3D.Content = Display3d(openfile);
	//Add the ModelVisual3D to the Children property of the HelixViewport3D

That seems extremely unlikely. I've never seen a WPF application stop firing events when the window is maximized.

Set a breakpoint of the first line of the loadbtn_Click event handler - you'll probably find that the event is being fired, but something else is going wrong. Perhaps the dialog is appearing behind your window?

If it's definitely not hitting the event handler, then there's something else going on. We'll need to see the relevant parts of your XAML.

Make sure that you pass the owning window, without it, it may be displaying behind your app maximized window. See: ShowDialog(Window) - Microsoft Learn[^]
