I have a simple tab control with 4 tab pages displayed under it.

I only wish to allow the user to change tab page once they have
filled out certain text boxes on each tab page (a wizard entry
type app).

My question: how can I prevent the user from changing tab page ?
(ie until they have entered the required data on each tab page).

Any help much appreciated.

Hello,

       Just put causevalidation at true for all of page in the tabcontrol. In the event validating of each page put the code who check if all conditions is ok.
Example :
    Private Sub TabPage1_Validating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TabPage1.Validating
        If text1.text = "" And text2.text = "" Then
            e.Cancel = True
        End If
    End Sub

         i hope that will help you
