Problem with Combobox and SelectedValue

Problem with Combobox and SelectedValue

• ptlsra

  Hi,
  
  I think the value changed event is not fired, because the selectedvalue should be set then to the right value, isn't it

  If you set AutoCompleteMode to Append and AutoCompleteSource to ListItems then you could tab through your combobox.

  Hi,
  let's first learn what is combobox. this is consider with using textbox, button and listbox right.
  lostfocus event is not a bug, but it is not handle easily so programer face some kind of problems.
  you have some knoledage about Overriding. This concept will solve your problem if your will foucs lost with using Tab key but if you focus lost with using mouse click than parallarly you have to handles a mouse click event for all componet except combo.
  about both combination will 100% solve you problems.
  1)protected overrides processcmdkey(.....)
  in body of the methods you will handle Tab and Enter key event and pick value from combobox to any variable as well as you want.
  end sub
  2)private sub control_MouseClick(byval sender as object, byval e as system.eventargs) _
  handles a1.mouseclick, b1.mouseclick, c1.mouseclick, etc
  in body of the routine you will handle Tab and Enter key event and pick value from combobox to any variable as well as you want.
  end sub

  Hi,
  
  try to make use of:
  
  LostFocusControl
  Occurs when the control loses focus.
  
  and
  
  

  FindString	Finds the first item in the T:System.Windows.Forms.ComboBox that starts with the specified string.
  FindStringExact	Finds the item that exactly matches the specified string.

  could be... I have not tried it before... but since he is using autocomplete, it can be trigered either by valuechanged or keypress

  Hi,
  
  I took that event of ComboBox from the online MSDN. I think you found an mistake in it, too

  I set the AutoCompleteMode to Append and the source to ListItems... and don't work. :(
  
  It's a bug in Beta2

  I just created a new project in Beta2. Dropped a Combobox, filled in some items. set AutoCompleteMode to Append and the source to ListItems. Added som textboxes to enable tabbing. And it just works fine. So there is some other option that you are setting and I don't.

  Thanks for the replays.
  
  I use this code in the "Leave" event. I don't find "LostFocusControl " in the ComboBox.
  
  Now works fine... thanks... but... i think this is a bug... ! :)
  
  

  Dim index As Integer                 index = MyComboBox.FindString(MyComboBoxComboBox.Text)                MyComboBoxComboBox.SelectedIndex = index

  Hi,
  You need to add this line;
  

  combobox1.SelectedValue = combobox1.Text
  
  in the aprpriate events. I think most apropriate would be valuechanged
  
  Good luck
