  Hi,

  You are wrong. When I click the mouse and want to show the context menu it appears near but the Left Top corner can be in another place then the mouse position.

  I took as base position that you tell but I found that is wrong.

  Thank's
  Alexei

  Hi,

  I checked. It's nice but I didn't get the position in context menu. I get the position of context menu container.

  Thank's

  Normally, the context menu will be shown at the center of the control when the keyboard is used to invoke the context menu of a control (Shift+F10, for example). You can customize the location as follows.

  Override WndProc in the grid and check if the Message.Msg is WM_CONTEXTMENU (0x007b)

  If so, check if the Message.LParam is -1, which means this was due to a keyboard message as opposed to the user right-clicking the mouse.

  Now, call the associated ContextMenu's Show method explicity at the selected row position.

  Make sure NOT to call the base class after showing the menu explicitly.

  protected override void WndProc(ref Message m)
  {
  if(m.Msg == 0x007B /*WM_CONTEXTMENU*/)
  {
  // LParam == -1 means that this is due to a keyboard message
  if((int)m.LParam == -1)
  {
  this.contextMenu.Show();
  return;
  }
  }
  }
  

  [VB.NET]

  Protected Overrides Sub WndProc(ByRef m As Message)
  If m.Msg = 0x007B Then 'WM_CONTEXTMENU
  ' LParam == -1 means that this is due to a keyboard message
  If (CType(m.LParam,Integer)) = -1 Then
  Me.contextMenu.Show()
  Return
  End If
  End If
  End Sub

  Hello Alex,

  If we get the mouse position at the time of displaying the contextmenu ,that is the top-left position of context menu.bcos the context menu will display in the same position of mouse pointer always.

  I think I had told this point in my first post.

  Hi

  The context menu will be displayed near to mouse always.So get the position of mouse using

  Control.MousePosition

  Alexei,

  Is this context menu for a form or some other control.If it for some other control,then add this method to that control.Put a breakpoint on the first line and see if code comes in there.

  Have you tried Control.MousePosition in popup event of contextmenu

  private void contextMenu1_Popup(object sender, System.EventArgs e)

  {

  Console.WriteLine(Control.MousePosition .ToString());

  }

  In the MouseUp Event of your panel write this code:

  
  

  if (e.Button == MouseButtons.Right)
  {
  Point contextMenuLocation = e.Location;
  MessageBox.Show(contextMenuLocation.ToString());
  }

  Hi Alexei,

  If you want the top-left of the context menu,then Point p in my example above has that value.Do you want the top-left position of the contextmenu or the point where the contextmenu was clicked

  In your form,use this bit of code to return the left-top co-ordinate of the contextmenu.

  protected override void WndProc(ref Message m)

  {

  if (m.Msg == 0x7b) //WM_CONTEXTMENU

  {

  Point p = Control.MousePosition;

  p = this.PointToClient(p); //Convert Screen to client coordinates

  this.CreateGraphics().DrawRectangle(Pens.Red,p.X,p.Y,100,100); //Proof that it works

  }

  base.WndProc(ref m);

  }

  Hope this helps.

  Hi,

  It doesn't work. It doesn't get into the if clause.

  Thank's
