How to hide TabPage from TabControl

How to hide TabPage from TabControl in WinForms 2 0

User · Answer

As a cheap work around  I ve used a label to cover up the tabs I wanted to hide   We can then use the visible prop of the label as a substitute   If anyone does go this route  don t forget to handle keyboard strokes or visibility events   You wouldn t want the left right cursor keys exposing the tab you re trying to hide

Well  if you don t want to mess up existing code and just want to hide a tab  you could modify the compiler generated code to comment the line which adds the tab to the tabcontrol   For example  The following line adds a tab named  readformatcardpage  to a Tabcontrol named  tabcontrol   this tabcontrol Controls Add this readformatcardpage    The following will prevent addition of the tab to the tabcontrol    this tabcontrol Controls Add this readformatcardpage

Visiblity property has not been implemented on the Tabpages  and there is no Insert method also   You need to manually insert and remove tab pages   Here is a work around for the same   http   www dotnetspider com resources 18344-Hiding-Showing-Tabpages-Tabcontrol aspx

I realize the question is old  and the accepted answer is old  but      At least in  NET 4 0      To hide a tab   tabControl TabPages Remove tabPage     To put it back   tabControl TabPages Insert index  tabPage     TabPages works so much better than Controls for this

Create a new empty class and past this inside it   using System Windows Forms   namespace ExtensionMethods       public static class TabPageExtensions                public static bool IsVisible this TabPage tabPage                        if  tabPage Parent    null                  return false              else if  tabPage Parent Contains tabPage                   return true              else                 return false                     public static void HidePage this TabPage tabPage                        TabControl parent    TabControl tabPage Parent              parent TabPages Remove tabPage                      public static void ShowPageInTabControl this TabPage tabPage TabControl parent                        parent TabPages Add tabPage                       2- Add reference to ExtensionMethods namespace in your form code   using ExtensionMethods    3- Now you can use yourTabPage IsVisible    to check its visibility  yourTabPage HidePage    to hide it  and yourTabPage ShowPageInTabControl parentTabControl   to show it

In WPF  it s pretty easy   Assuming you ve given the TabItem a name  e g     lt TabItem Header  Admin  Name  adminTab  Visibility  Hidden  gt   lt  -- tab content -- gt   lt  TabItem gt    You could have the following in the code behind the form    if  user AccessLevel    AccessLevelEnum Admin          adminTab Visibility   System Windows Visibility Visible       It should be noted that a User object named user has been created with it s AccessLevel property set to one of the user-defined enum values of AccessLevelEnum    whatever  it s just a condition by which I decide to show the tab or not

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

I ve used the same approach but the problem is that when tab page was removed from the tab control TabPages list  it is removed from the tab page Controls list also  And it is not disposed when form is disposed    So if you have a lot of such  hidden  tab pages  you can get windows handle quota exceeded error  and only application restart will fix it

I also had this question   tabPage Visible is not implemented as stated earlier  which was a great help   1    I found you can override the control and this will work   A bit of necroposting  but I thought to post my solution here for others          System ComponentModel DesignerCategory  Code    public class MyTabPage   TabPage       private TabControl  parent      private bool  isVisible      private int  index      public new bool Visible               get   return  isVisible            set                       if   parent    null   parent   this Parent as TabControl              if   parent    null  return               if   index  lt  0   index    parent TabPages IndexOf this               if  value  amp  amp    parent TabPages Contains this                                 if   index  gt  0   parent TabPages Insert  index  this                   else  parent TabPages Add this                             else if   value  amp  amp   parent TabPages Contains this    parent TabPages Remove this                 isVisible   value              base Visible   value                       protected override void InitLayout                 base InitLayout             parent   Parent as TabControl
