But the thing is I also want to be able to add textboxes etc in this popup window thru the form designer    It s unclear from your description at what stage in the development process you re in   If you haven t already figured it out  to create a new Form you click on Project --  Add Windows Form  then type in a name for the form and hit the  Add  button   Now you can add controls to your form as you d expect   When it comes time to display it  follow the advice of the other posts to create an instance and call Show   or ShowDialog   as appropriate

This is not so easy because basically popups are not supported in windows forms  Although windows forms is based on win32 and in win32 popup are supported  If you accept a few tricks  following code will set you going with a popup  You decide if you want to put it to good use    class PopupWindow   Control       private const int WM ACTIVATE   0x0006      private const int WM MOUSEACTIVATE   0x0021       private Control ownerControl       public PopupWindow Control ownerControl           base                 this ownerControl   ownerControl          base SetTopLevel true              public Control OwnerControl               get                       return  this ownerControl as Control                     set                       this ownerControl   value                       protected override CreateParams CreateParams               get                       CreateParams createParams   base CreateParams               createParams Style   WindowStyles WS POPUP                                    WindowStyles WS VISIBLE                                    WindowStyles WS CLIPSIBLINGS                                    WindowStyles WS CLIPCHILDREN                                    WindowStyles WS MAXIMIZEBOX                                    WindowStyles WS BORDER              createParams ExStyle   WindowsExtendedStyles WS EX LEFT                                      WindowsExtendedStyles WS EX LTRREADING                                      WindowsExtendedStyles WS EX RIGHTSCROLLBAR                                       WindowsExtendedStyles WS EX TOPMOST               createParams Parent    this ownerControl    null    this ownerControl Handle   IntPtr Zero              return createParams                        DllImport  user32 dll   CharSet   CharSet Auto  ExactSpelling   true       public static extern IntPtr SetActiveWindow HandleRef hWnd        protected override void WndProc ref Message m                switch  m Msg                        case WM ACTIVATE                                        if   int m WParam    1                                                  window is being activated                         if  ownerControl    null                                                        SetActiveWindow new HandleRef this  ownerControl FindForm   Handle                                                                        break                                case WM MOUSEACTIVATE                                        m Result   new IntPtr MouseActivate MA NOACTIVATE                       return                        break                                      base WndProc ref m              protected override void OnPaint PaintEventArgs e                base OnPaint e           e Graphics FillRectangle SystemBrushes Info  0  0  Width  Height           e Graphics DrawString  ownerControl as VerticalDateScrollBar  FirstVisibleDate ToLongDateString    this Font  SystemBrushes InfoText  2  2             Experiment with it a bit  you have to play around with its position and its size  Use it wrong and nothing shows

Just create another form  let s call it formPopup  using Visual Studio  In a button handler write the following code   var formPopup   new Form    formPopup Show this      if you need non-modal window   If you need a non-modal window use  formPopup Show     If you need a dialog  so your code will hang on this invocation until you close the opened form  use  formPopup ShowDialog

If you mean to create a new form when a button is clicked  the below code may be of some use to you   private void settingsButton Click Object sender  EventArgs e           Create a new instance of the Form2 class     Form2 settingsForm   new Form2            Show the settings form     settingsForm Show        From here  you could also use the  Show Dialog  method

Forms in C  are classes that inherit the Form base class   You can show a popup by creating an instance of the class and calling ShowDialog
