Hi Guys,

Just having an issue that has completely stumped me.

In a nutshell, how to hide/show certain controls when a tabpage is changed?
ie. when the tabpage 1 is switched to tabpage 2 by the users, I want to hide the menustrip and toolbar.

The TabControl object has an event called Selected.

When a new tab is selected, this event fires. One of the objects included in the event's arguments is the TabPage that was just selected.

So, in the method, you can check e.TabPage.Name and see if you want to show or hide the controls.

Check KSchuler's answer. He's got the right event identified.

Well, just like with any control, there are multiple events that one could use. If you look at the code for the TabControl, specifically the WmSelChange() method, what you will find is that OnSelected is fired immediately before OnSelectedIndexChanged. And with the SelectedIndexChanged event, you don't get anything in your arguments.

But with the Selected event, you get passed not only the SelectedTab object, but also the SelectedIndex number. This means that the SelectedTab event is a more self-contained solution and a better one.

The Selected event is under the category of Action. Or, you can switch to the alphabetical view and find it right after RightToLeftLayoutChanged.
I use the TabControl's SelectedIndexChanged Event. Make sure you are looking at events for the TabControl not the TabPage. You can include code that checks which TabPage is selected like this:

Private Sub tcMyTabControl_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles tcMyTabControl.SelectedIndexChanged
       'If newly selected tab is tabpage2
       If tcMyTabControl.SelectedTab Is tpTabPage2 Then
          'Hide menu/toolbar
          'Show menu/toolbar           
       End If
End Sub

Hope this helps.

This is the right one - a 5.

What exactly makes it the "right" one. As far as I can see, using SelectedIndexChanged or Selected is personal preference and therefore there is no right or wrong!
