Is it possible to hide a tab page of tab control?

You can remove a tab page from the control;

TabPage removedTab = tabControl1.TabPages[1];

tabControl1.TabPages.Remove(removedTab);

If you then store the removedTab you then add or insert it back into the tab page collection with;

if (removedTab != null)
{
    tabControl1.TabPages.Insert(1, removedTab);
}

or

if (removedTab != null)
{
   tabControl1.TabPages.Add(removedTab);
}
