Hiding and Showing TabPages in tabControl

Question

I am trying to show or hide tabpages as per user choice. If user selects gender male then form for male in a tabpage "male" should be displayed and if user selects female then similar next form should be displayed in next tab "female"

I tried using

tabControl1.TabPages.Remove(...) 

and

tabControl1.TabPages.Add(...) 

It adds and removes the tabpages but doing so will loose my controls on tabpages too... i can't see them back. what's the problem here?

Answer 1

I think the answer is much easier.

To hide the tab you just can use the way you already tried or adressing the TabPage itself.

TabControl1.TabPages.Remove(TabPage1) 'Could be male TabControl1.TabPages.Remove(TabPage2) 'Could be female 

a.s.o.

Removing the TabPage does not destroy it and the controls on it. To show the corresponding tab again just use the following code

TabControl1.TabPages.Insert(0, TabPage1) 'Show male TabControl1.TabPages.Insert(1, TabPage2) 'Show female 

Answer 2

You could remove the tab page from the TabControl.TabPages collection and store it in a list. For example:

    private List<TabPage> hiddenPages = new List<TabPage>();      private void EnablePage(TabPage page, bool enable) {         if (enable) {             tabControl1.TabPages.Add(page);             hiddenPages.Remove(page);         }         else {             tabControl1.TabPages.Remove(page);             hiddenPages.Add(page);         }     }      protected override void OnFormClosed(FormClosedEventArgs e) {         foreach (var page in hiddenPages) page.Dispose();         base.OnFormClosed(e);     }
