VB.Net Hide Tabpage

Question

Ive seen some discussion on here about how to hide tabs in a tabcontrol but they all seem to be in C or some variant. I havent seen one for vb.net (i cant do C)

What

Answer 1

Currently, the following code block disables all the controls on that TabPage (Sets Control.Enabled = False). The tab itself is still visible and selectable from the TabControl, it is not hidden. The tab is selectable and all the elements appear disabled.

TabMyTab.Enabled = False

If you want to disable the tab similar to i.e. button.Enabled = False which does not allow the control to be used, you will need to do something different as disabling a TabPage as in the code above disables all controls in that tab. If this is what you want, keep reading. A lot of programmers suggest using the TabControl to disallow the tab from being selected by selecting a different or the previously selected tab. This is the most effective way I know. I would implement this as follows:

Private PreviousTab As New TabPage
Private CurrentTab As New TabPage

Private Sub TabControlName_Deselected(ByVal sender As Object, ByVal e As System.Windows.Forms.TabControlEventArgs) Handles TabControlName.Deselected
        PreviousTab = e.TabPage
End Sub

Private Sub TabControlName_Selected(ByVal sender As Object, ByVal e As System.Windows.Forms.TabControlEventArgs) Handles TabControlName.Selected
        CurrentTab = e.TabPage
        If (PreviousTab.Name <> CurrentTab.Name) And (CurrentTab.Name = UnselectableTab.Name) Then
            MessageBox.Show("Tab disabled.", "Selection Error", MessageBoxButtons.OK, MessageBoxIcon.Warning)
            TabControlName.SelectedTab = PreviousTab
        End If
End Sub

Substitute your own values for "UnselectableTab" and "TabControlName" for your project.
