How can I disable a tab inside a TabControl?

Is there a way to disable a tab in a TabControl?

Solution

  • The TabPage class hides the Enabled property. That was intentional as there is an awkward UI design problem with it. The basic issue is that disabling the page does not also disable the tab. And if try to work around that by disabling the tab with the Selecting event then it does not work when the TabControl has only one page.

    If these usability problems do not concern you then keep in mind that the property still works, it is merely hidden from IntelliSense. If the FUD is uncomfortable then you can simply do this:

    public static void EnableTab(TabPage page, bool enable) {
    foreach (Control ctl in page.Controls) ctl.Enabled = enable;
}
