User · Answer

I had to handle this a while back  I removed the Tab from the TabPages collection  I think that s it  and added it back in when the conditions changed  But that was only in Winforms where I could keep the tab around until I needed it again

You could register the  Selecting  event and cancel the navigation to the tab page   private void tabControl1 Selecting object sender  TabControlCancelEventArgs e        if  e TabPage    tabPage2          e Cancel   true      Another idea is to put all the controls on the tabpage in a Panel control and disable the panel  Smiley  You could also remove the tabpage from the tabControl1 TabPages collection  That would hide the tabpage   Credits go to littleguru   Channel 9

The user cannot click on tabs to navigate  but they can use the two buttons  Next and Back   The user cannot continue to the next if the   conditions are no met   private int currentTab   0   private void frmOneTimeEntry Load object sender  EventArgs e        tabMenu Selecting    new TabControlCancelEventHandler tabMenu Selecting      private void tabMenu Selecting object sender  TabControlCancelEventArgs e        tabMenu SelectTab currentTab      private void btnNextStep Click object sender  EventArgs e        switch tabMenu SelectedIndex                case 0                if conditions met GoTo         case 2                if conditions met GoTo         case n                if conditions met GoTo           CanLeaveTab      currentTab        tabMenu SelectTab tabMenu SelectedIndex   1       if  tabMenu SelectedIndex    3          btnNextStep Enabled   false      if  btnBackStep Enabled    false          btnBackStep Enabled   true       CannotLeaveTab               private void btnBackStep Click object sender  EventArgs e        currentTab--      tabMenu SelectTab tabMenu SelectedIndex - 1       if  tabMenu SelectedIndex    0          btnBackStep Enabled   false      if  btnNextStep Enabled    false          btnNextStep Enabled   true

Cast your TabPage to a Control  then set the Enabled property to false     Control this tabPage  Enabled   false    Therefore  the tabpage s header will still be enabled but its contents will be disabled

I could not find an appropriate answer to the question  There looks to be no solution to disable the specific tab  What I did is to pass the specific tab to a variable and in SelectedIndexChanged event put it back to SelectedIndex     variable for your specific tab  int  TAB   0     here you specify your tab that you want to expose  TAB   1  tabHolder SelectedIndex    TAB   private void tabHolder SelectedIndexChanged object sender  EventArgs e        if   TAB    0  tabHolder SelectedIndex    TAB      So  you don t actually disable the tab  but when another tab is clicked it always returns you to the selected tab

in C  7 0  there is a new feature called Pattern Matching  You can disable all tabs via Type Pattern  foreach  Control control in Controls           the is expression tests the variable and         assigned it to a new appropriate variable type     if  control is TabControl tabs                tabs Enabled   false

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
