Hi
U cant hide tabs in windows forms application.U should add and remove tabs according to your users

eg.

C#

if (textBox1.Text == "z" && textBox2.Text == "t")
       {
           this.Hide();
           Form1 fr1 = new Form1();
          //how can I hide tabpage2 and tabpage3 on form1(fr1) for this user
tabControl1.TabPages.Remove(tabpage2);
tabControl1.TabPages.Remove(tabpage3 );
           fr1.ShowDialog();
       }

Your problem, I guess, was, that .Hide() and .Visible = false didn't work out as assumed...

You have to remove it from the TabPages of your control... something like this

C#

if (this.tabControl1.TabPages.Contains(this.tabPage2))
    this.tabControl1.TabPages.Remove(this.tabPage2);
else
    this.tabControl1.TabPages.Add(this.tabPage2);

Remember, this is just a hint... don't just copy&paste it...

I read before in Internet that I have to remove them but my problem is I want to remove it from fr1(form1) not loginform then "this" phrase is not applicable for me cause login form does not have any tab.

Ok... then you have to create a public method to hide/show them accordingly to your use case. Don't just make the methods public, rather create a method which handles this.

Sth like

fr1.hideFirstTab();
fr1.showFirstTab();

or more generic

fr1.hideTabWithThis([Index/Name of the tab]);
fr1.showTabWithThis([Index/Name of the tab]);

To be honest, I would choose an approach that decides itself, what would be neccessary to handle the cases...

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.
may be like below code

C#

private System.Windows.Forms.TabControl _tabControl;
private System.Windows.Forms.TabPage _tabPage1;
private System.Windows.Forms.TabPage _tabPage2;

...

// Initialise the controls

...

// "hides" tab page 2
_tabControl.TabPages.Remove(_tabPage2);

// "shows" tab page 2
if (_tabControl.TabPages.Contains(_tabPage2))
{
    _tabControl.TabPages.Add(_tabPage2);
}
