Accepted Answer

No, this doesn't exist. You have to remove the tab and re-add it when you want it. Or use a different (3rd-party) tab control.

I realize the question is old, and the accepted answer is old, but ...

At least in .NET 4.0 ...

To hide a tab:

tabControl.TabPages.Remove(tabPage);

To put it back:

tabControl.TabPages.Insert(index, tabPage);

TabPages works so much better than Controls for this.

Visiblity property has not been implemented on the Tabpages, and there is no Insert method also.

You need to manually insert and remove tab pages.

Here is a work around for the same.

Variant 1

In order to avoid visual klikering you might need to use:

bindingSource.RaiseListChangeEvent = false 

or

myTabControl.RaiseSelectedIndexChanged = false

Remove a tab page:

myTabControl.Remove(myTabPage);

Add a tab page:

myTabControl.Add(myTabPage);

Insert a tab page at specific location:

myTabControl.Insert(2, myTabPage);

Do not forget to revers the changes:

bindingSource.RaiseListChangeEvent = true;

or

myTabControl.RaiseSelectedIndexChanged = true;

Variant 2

myTabPage.parent = null;
myTabPage.parent = myTabControl;

Solutions provided so far are way too complicated. Read the easiest solution at: http://www.codeproject.com/Questions/614157/How-to-Hide-TabControl-Headers

You could use this method to make them invisible at run time:

private void HideAllTabsOnTabControl(TabControl theTabControl)
{
  theTabControl.Appearance = TabAppearance.FlatButtons;
  theTabControl.ItemSize = new Size(0, 1);
  theTabControl.SizeMode = TabSizeMode.Fixed;
}

I combined the answer from @Jack Griffin and the one from @amazedsaint (the dotnetspider code snippet respectively) into a single TabControlHelper.

The TabControlHelper lets you:

  • Show / Hide all tab pages
  • Show / Hide single tab pages
  • Keep the original position of the tab pages
  • Swap tab pages

public class TabControlHelper
{
    private TabControl _tabControl;
    private List<KeyValuePair<TabPage, int>> _pagesIndexed;
    public TabControlHelper(TabControl tabControl)
    {
        _tabControl = tabControl;
        _pagesIndexed = new List<KeyValuePair<TabPage, int>>();

        for (int i = 0; i < tabControl.TabPages.Count; i++)
        {
            _pagesIndexed.Add(new KeyValuePair<TabPage, int> (tabControl.TabPages[i], i ));
        }
    }

    public void HideAllPages()
    {
        for (int i = 0; i < _pagesIndexed.Count; i++)
        {
            _tabControl.TabPages.Remove(_pagesIndexed[i].Key);
        }
    }

    public void ShowAllPages()
    {
        for (int i = 0; i < _pagesIndexed.Count; i++)
        {
            _tabControl.TabPages.Add(_pagesIndexed[i].Key);
        }
    }

    public void HidePage(TabPage tabpage)
    {
        if (!_tabControl.TabPages.Contains(tabpage)) return;
        _tabControl.TabPages.Remove(tabpage);
    }

    public void ShowPage(TabPage tabpage)
    {
        if (_tabControl.TabPages.Contains(tabpage)) return;
        InsertTabPage(GetTabPage(tabpage).Key, GetTabPage(tabpage).Value);
    }

    private void InsertTabPage(TabPage tabpage, int index)
    {
        if (index < 0 || index > _tabControl.TabCount)
            throw new ArgumentException("Index out of Range.");
        _tabControl.TabPages.Add(tabpage);
        if (index < _tabControl.TabCount - 1)
            do
            {
                SwapTabPages(tabpage, (_tabControl.TabPages[_tabControl.TabPages.IndexOf(tabpage) - 1]));
            }
            while (_tabControl.TabPages.IndexOf(tabpage) != index);
        _tabControl.SelectedTab = tabpage;
    }

    private void SwapTabPages(TabPage tabpage1, TabPage tabpage2)
    {
        if (_tabControl.TabPages.Contains(tabpage1) == false || _tabControl.TabPages.Contains(tabpage2) == false)
            throw new ArgumentException("TabPages must be in the TabControls TabPageCollection.");

        int Index1 = _tabControl.TabPages.IndexOf(tabpage1);
        int Index2 = _tabControl.TabPages.IndexOf(tabpage2);
        _tabControl.TabPages[Index1] = tabpage2;
        _tabControl.TabPages[Index2] = tabpage1;
    }

    private KeyValuePair<TabPage, int> GetTabPage(TabPage tabpage)
    {
        return _pagesIndexed.Where(p => p.Key == tabpage).First();
    }
}
