How can I disable a tab inside a TabControl

Question

Is there a way to disable a tab in a TabControl

User · Answer

You can do it through the tabpages  tabPage1 Hide    tabPage2 Show   etc

User · Answer

You can simply use   tabPage Enabled   false    This property is not shown  but it works without any problems   You can program the Selecting event on TabControler to make it impossible to change to a non-editable tab   private void tabControler Selecting object sender  TabControlCancelEventArgs e        if  e TabPageIndex  lt  0  return      e Cancel    e TabPage Enabled

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

The only way is to catch the Selecting event and prevent a tab from being activated

User · Answer

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

Using events  and the properties of the tab control you can enable disable what you want when you want  I used one bool that is available to all methods in the mdi child form class where the tabControl is being used    Remember the selecting event fires every time any tab is clicked  For large numbers of tabs a  CASE  might be easier to use than a bunch of ifs   public partial class Form2   Form               bool formComplete   false           public Form2                         InitializeComponent                        private void button1 Click object sender  EventArgs e                          formComplete   true              tabControl1 SelectTab 1                       private void tabControl1 Selecting object sender  TabControlCancelEventArgs e                        if  tabControl1 SelectedTab    tabControl1 TabPages 1                                  tabControl1 Enabled   false                   if  formComplete                                        MessageBox Show  You will be taken to next tab                        tabControl1 SelectTab 1                                      else                                       MessageBox Show  Try completing form first                        tabControl1 SelectTab 0                                     tabControl1 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
