C# playing embedded Windows Media Player in fullscreen

Question

I'm working on my eyetracking Windows Forms application. I need to play a video and keep track of eye movements simultaneously. Eyetracking part is done, now I need to open a video. I can open a DialogBox to choose which video to play, but I need to have a fullscreen, in order to make more accurate operations.

In my VideoStream class I have got :

public static string videoPath;
    public VideoStream(string path)
    {
        InitializeComponent();
        videoPath = path;
        axWindowsMediaPlayer1.URL = videoPath;
        axWindowsMediaPlayer1.Dock = DockStyle.Fill;
    }

with the dockstyle fill, I can make my form maximized, but the video is just playing in a small screen like this

but what I want is actually this

I tried to use axWindowsMediaPlayer1.fullScreen = true; but just expands the borders of the form, not the video itself. How can I solve this?

Answer 1

Try adding these lines after initializeComponent():

FormBorderStyle = FormBorderStyle.None;
WindowsState = FormWindowState.Maximized;
TopMost = true;
