    Load events happens at strange times

    I have a Form (FV&C) containing a userconrtrol (CF&E)

    I do a ShowDialog for the form and the form's Load calls a method of the
    UserControl.

    The first time I do this the usercontrol appears on the form as I'd expect
    after the method had been run.

    The second time I do this the usercontrol appears on the form as if the
    usercontrols Load had last been run.

    I peppered the code with writes and the following resulted.

    Note that for the fist time, the usercontrol's Load runs before the form's
    Load starts.

    But, notice at the bottom of the list that for the second time, the
    usercontrol's Load runs after the form's Load ends.

    Does this make sense to you?

    Any suggestions as to what is going on?

    I need to have the CF&E Load run before the called method or better, if the
    usercontrol remember from the last time, not to run at all.

    Thanks

      My guess is you are not using a form variable, but rather loading the
      form directly. Using a form variable, you will then call New, and the
      process should proceed as in the first portion.

          Re: Load events happens at strange times

          Maybe the problem is because I use the same Form variable for two
          ShowDialog's.
          As normal with ShowDialog, the form is closed at the end of the first
          ShowDialog run.
          What happens the second time I do ShowDialog

          I think that must be the problem.
          I want to keep the form around because it contains data that I need.
          So I do ShowDialog on the form
          The form closes itself when finshed
          I do ShowDialog later thinking ( maybe not thinking clearly) that my data
          will still be there and the form will simply become visible.



          In Declarations I do
          Friend WithEvents mFormVolAndChap s1 As CAG.formVolAndC haps.FormVolAnd Chaps =
          New CAG.formVolAndC haps.FormVolAnd Chaps



          On menuitem click event I do

          Console.WriteLi ne("Call FV&C method")

          mFormVolAndChap s1.Action =
          FormVolAndChaps .FormVolAndChap s.ActionType.Cr eateNewVolumeFo lder

          Console.WriteLi ne("FV&C.ShowDi alog")

          mFormVolAndChap s1.ShowDialog()

          Console.WriteLi ne("FV&C.ShowDi alog Returned")

          ' It's the second time I click that I have a problem.

          ' I've noticed that the usercontrol Visible property is True the
          first time and False the second time!




          Comments?

          I believe the above procedure would be OK if I were using Show instead of
          ShowDilog - correct?


          Thanks
