Came across this when looking for something. Your code above does not work if any of the tabs are invisible as the selected tab becomes nothing so it crashes when checking the index. It also don't work right well even if it did not crash because you end up on the hidden tab being selected, rather than the next non-hidden task.

Here is what I suggest.

 

Public Sub btnNext_Click(sender As System.Object, e As System.EventArgs) Handles btnNext.Click

Dim visInd As Integer

visInd = uTabOptions.ActiveTab.VisibleIndex

Do

visInd += 1

uTabOptions.SelectedTab = uTabOptions.Tabs(visInd)

Loop Until uTabOptions.SelectedTab IsNot Nothing Or visInd >= uTabOptions.Tabs.Count

End Sub

Public Sub btnback_Click(sender As System.Object, e As System.EventArgs) Handles btnback.Click

Dim visInd As Integer

visInd = uTabOptions.ActiveTab.VisibleIndex

Do

visInd -= 1

uTabOptions.SelectedTab = uTabOptions.Tabs(visInd)

Loop Until uTabOptions.SelectedTab IsNot Nothing Or visInd <= 0

End Sub

Hello MisterRafter,

Danko thanks,

i did convert your code into vb.net and got it to run. Thanks for your code explanation, all makes sense now.

Hello MisterRafter,

Here is the same code in VB :

Private Sub UltraButton1_Click(sender As System.Object, e As System.EventArgs) Handles UltraButton1.Click
        If UltraTabControl1.SelectedTab IsNot Nothing AndAlso UltraTabControl1.SelectedTab.Index + 1 < UltraTabControl1.Tabs.Count Then
            UltraTabControl1.Tabs(UltraTabControl1.SelectedTab.Index + 1).Selected = True
        End If
    End Sub

Here in the button click event handler the code is verifying if there is a selected tab at all, and if so verifies if the next possible tab should be within the collection, and if both of those are true, it just selects the next tab after the already selected one.

If you need further assistance with this please feel free to let us know.

perfect that works. Star! thanks

now i need to understand the code you provided. Im fairly new to VB.net :)
