Answer 1

There is no direct way to disable Tab Page, only you can remove it. But in your case, you can't remove the Tab, So I think you need to put some code in the Tab_SelectionIndex change event. And when ever the Tab index comes, set it back to another one.

Try this code

private void tabControl1_SelectedIndexChanged(object sender, EventArgs e)
{
if (tabControl1.SelectedIndex == 1)
{
tabControl1.SelectedIndex = -1;
}
}

In addition to anuraj's answer, set the colour of the tab text to the disabled text colour state, so it is a visual cue it is "disabled".

Answer 3

Use something besides a tab panel.

It is not standard behavior for a tab panel to have one tab "stuck" so that the user cannot move to the other tabs. You're going to throw users off if you do this.

What you are after sounds like a modal dialog. It sounds like you don't want the users to move away from a certain screen until they're doing entering some data or some such. The modal dialog is built for this purpose.
