Disable maximize button of WPF window, keeping resizing feature intact
WPF does not have the native capability to disable the Maximize button alone, as you can do with WinForms. You will need to resort to a WinAPI call. It's not scary:
[DllImport("user32.dll")]private static extern int GetWindowLong(IntPtr hWnd, int nIndex);[DllImport("user32.dll")]private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);private const int GWL_STYLE = -16;private const int WS_MAXIMIZEBOX = 0x10000;private void Window_SourceInitialized(object sender, EventArgs e){ var hwnd = new WindowInteropHelper((Window)sender).Handle; var value = GetWindowLong(hwnd, GWL_STYLE); SetWindowLong(hwnd, GWL_STYLE, (int)(value & ~WS_MAXIMIZEBOX));}
