Taskbar disappeared when set WindowState to Maximized.

[wk-j]

In MaterialForm if set WindowsState to Maximized (in Properties Windows) form will display as fullscreen.

Problem

• Taskbar disappeared.
• Restore button not working.

I'm try to fix with this code but restore button still not working.

        private void Form_Load(object sender, EventArgs e)
        {
            MaximizeWindow(true);
        }
        /*
            Fix Full Screen
        */
        private Size previousSize;
        private Point previousLocation;
        private const int MONITOR_DEFAULTTONEAREST = 2;

        private void MaximizeWindow(bool maximize)
        {
            if (maximize)
            {
                IntPtr monitorHandle = MonitorFromWindow(Handle, MONITOR_DEFAULTTONEAREST);
                MONITORINFOEX monitorInfo = new MONITORINFOEX();
                GetMonitorInfo(new HandleRef(null, monitorHandle), monitorInfo);
                previousSize = Size;
                previousLocation = Location;
                Size = new Size(monitorInfo.rcWork.Width(), monitorInfo.rcWork.Height());
                Location = new Point(monitorInfo.rcMonitor.left, monitorInfo.rcMonitor.top);
            }
            else
            {
                Size = previousSize;
                Location = previousLocation;
            }
        }
