no. me.refresh will just update
its actually depends on what exactlly you wish to reset like textboxes, checkboxes and so on.
you could do an function like:
vb Syntax (Toggle Plain Text) 
  1. private sub ClearCtrl
  2. for each ctrl as control in Form1
  3. try
  4. if typeof(ctrl) is checkbox then ctrl.checked=false
  5. if typeof(ctrl) is textbox then ctrl.clear
  6. catch as exception
  7. 'catch the containers here
  8. end try
  9. next
end sub

something like that

I don't get a word "reset". Do you want to reset the state of controls or just clear the text or setting up selectedindex with 0?

vb.net Syntax (Toggle Plain Text) 
  1. For Each c As Control In Me.Controls
  2.   If TypeOf c Is TextBox Then
  3.      CType(c, TextBox).Text = String.Empty
  4.   End If
  5. Next

cant edit my post anymore. but since adatapost told me its not working i did a test and its working

vb Syntax (Toggle Plain Text) 
  1.   For Each ctrl As Control In Me.Controls
  2.             Try
  3.                 If TypeOf (ctrl) Is CheckBox Then DirectCast(ctrl, CheckBox).Checked = False
  4.                 If TypeOf (ctrl) Is TextBox Then DirectCast(ctrl, TextBox).Clear()
  5.             Catch ex As Exception
  6.                 'catch the containers here
  7.             End Try
  8.         Next

works as it is and only if you dont have the controls inside containers such as panels, groupboxes then you need to recurse these aswell.

@GeekByChoice : it should be "for each ctrl as control in Form1.controls".
-- It must be Me.Controls.

isn't there a centralised option for resetting the from...

like am using a user specified array of custom controls on a flow panel connecting to a database.

Now how do i reset the data to it's initial state if the user presses a button called reset

Dispose the form and re-instantiate it to the state defined by the contructor(s). However I am almost certain this is not what you want so please clarify what you are doing, and what you would like to do.
