i have a wizard control , i tried to put all the insert command and update commands withing the ( Next , Previous ) buttons of the wizard , the code i use is :

Protected Sub Wizard1_PreviousButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.PreviousButtonClick
        Select Case e.CurrentStepIndex
            Case 2
                Select Case FormView2.CurrentMode
                    Case FormViewMode.Insert
                        FormView2.InsertItem(True)


                    Case FormViewMode.Edit
                        FormView2.UpdateItem(True)

                End Select


        End Select
    End Sub


when i test this code , i get the following error

Page.IsValid cannot be called before validation has taken place. It should be queried in the event handler for a control that has CausesValidation=True and initiated the postback, or after a call to Page.Validate.


any help on this issue ?

Control validation has to be done. If it is valid then Page.Validate() should be called in your method. Please check the link:  http://forums.asp.net/t/1106963.aspx/1
