How to hide TabPage from TabControl

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.

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.

I also had this question. tabPage.Visible is not implemented as stated earlier, which was a great help (+1). I found you can override the control and this will work. A bit of necroposting, but I thought to post my solution here for others...

    [System.ComponentModel.DesignerCategory("Code")]
public class MyTabPage : TabPage
{
    private TabControl _parent;
    private bool _isVisible;
    private int _index;
    public new bool Visible
    {
        get { return _isVisible; }
        set
        {
            if (_parent == null) _parent = this.Parent as TabControl;
            if (_parent == null) return;

            if (_index < 0) _index = _parent.TabPages.IndexOf(this);
            if (value && !_parent.TabPages.Contains(this))
            {
                if (_index > 0) _parent.TabPages.Insert(_index, this);
                else _parent.TabPages.Add(this);
            }
            else if (!value && _parent.TabPages.Contains(this)) _parent.TabPages.Remove(this);

            _isVisible = value;
            base.Visible = value;
        }
    }

    protected override void InitLayout()
    {
        base.InitLayout();
        _parent = Parent as TabControl;
    }
}
