Hi
In my wizard page-handling code I have been using the SelectionChanging event to control the setting up of the next wizard page according to previous selections. This includes setting the visibility of certain controls. However, I have noticed that while in this event, all controls on the new wizard page are visible=false.
Am I supposed to be using the SelectionChanged event for code that initialises a page? One of the reasons I've been using SelectionChanging is because I don't want the code to be executed if navigating backwards through pages, so have used something like "If e.Reason = ActiproSoftware.Wizard.WizardPageEventReason.BackButtonClick Then Exit Sub".
I have tried calling the page initialisation code from SelectionChanged but have noticed there is a lot of flicker from the controls (have tried using SuspendLayout on the wizard page with no difference).
Ideally, I'd like to leave the page initialisation code in SelectionChanging, however I still need to ensure controls are visible according to previous selections.
A sample of my code:Thanks
Richard

Select Case wizWizard.SelectedPage.Name
Case wpReportingOptions.Name
SetupReportingOptionsPage()
'other cases removed
End select
End Sub
Private Sub SetupReportingOptionsPage()
'set control visibility according to options selected on previous pages
lblDescription.Visible = someValueOnPreviousPage
'TODO: the setting of the above value is ignored here
'something to do with the wizard page not being initialised yet
end sub
