How do i get rid of the body in my tabControl? and how do i add and remove tabpages? I need to add/remove tabpages in code but hide the body in code or in the editor. I tried making the tabControl hight <20 but no matter what it has a line showing how wide it is.
As far as I know, there's no built-in control for a row of tabs without pages for each tab.
You could just cover the body with a Panel. If you adjust the size of the panel carefully, it should look ok.
What do you mean by "hide the body"? If you mean the "page" part of the tab, it's not really a tab page any more if you can only see the labels. What are you trying to accomplish? It may well be that a tab control isn't the best approach.
You can create new tab pages in code and add them to the TabControl's Controls collection:
private System.Windows.Forms.TabPage tabPage1;
this.tabPage1 = new System.Windows.Forms.TabPage();
this.tabControl1.Controls.Add(this.tabPage1);
You can hide the tab control from code with this:
tabControl1.Hide();
To hide the tabpage from the user you just remove it from the tabControl.TabPages collection like so:
tabControl1.TabPages.Remove(tabPage1);

I'm using tabControl with many tabs(>10), and each tab has UserContol. But tabs Initialize each control at starting my app. It's making my program too slow. I want to run my userControl only when I click on it. How can I do this?
You should improve your UserControls that they do not do the performance stuff until they get activated/visible. Give them a method Activate which the tabcontrol calls when the tabs becomes the selected tab.
Alternatively you could not add the UserControls to the TabPage content in the designer. Instead create your UserControl when the tab becomes active. But this will make them insivible in the Designer.
You could either have a marker such as IsLoaded and until a tab is selected, not load the controls. When the tab is then selected, if it hasn't already been loaded, you could load the controls and add them at runtime to the tabs Controls.
Or, you could have the controls added but not do anything with them until the tab is selected, and then each tab will do the calculations or whatever and update the correct controls.
It's all about your design.
Add a handler to your UserControl's Load event. Then kick off slow activity in the handler.
I have a TabControl which I have designed in the VS2005 designer that has about 7 tabs.
How can I easily switch the order of the tabs around?
I put one tab at the end in a rush, but now I want it somewhere in the middle.
In the properties of the tab control there's a TabPages collection. You should be able to shuffle them around in there. Just click the ellipses next to TabPages and a dialog will appear allowing you to move each one up or down in the order.
Mark the TabControl in the Designer.
In the Properties Window (F4) you have a TabPages Property.
You can open a new Window where you can reorder the TabPages.
If you want to do that at runtime you have to do
tabControl.TabPages.Remove(tabPage1);
tabControl.TabPages.Add(tabPage1); // add to the end
tabControl.TabPages.Insert(2, tabPage1); // add on specific position
Open FormName.Designer.cs.
Find the line this.tabControl1.Controls.Add ....
You can change the order here.

In my previous question I could add a design time panel to a tab page at run time and my code looks like this and it works Ok.
tabControl1.SuspendLayout();
tabControl1.TabPages[0].Controls.Add(panel1);
tabControl1.ResumeLayout();
but now I need to do something like this:
tabControl1.SuspendLayout();
tabControl1.TabPages[0].Controls.Add(panel1);
tabControl1.TabPages[1].Controls.Add(panel1);
tabControl1.TabPages[2].Controls.Add(panel1);
tabControl1.ResumeLayout();
which just at run-time I can know how many of these Tabpages I will need. but now for testing I am assuming I will have three tabPages
the Problem is that the panel only gets added to the Last tabPage,
How can I fix this? I want it get added to all of the tab pages
Thanks.
You can't. A control can have only one parent at a time. Luckily, only one tab page is visible at a time, so I guess you could move the panel between the pages as they are displayed? On the other hand, if the panel is to be located in the same place for all pages, perhaps it should not be placed inside the tab control, but rather on top of it?
I have six tabs on my Windows application. I need to put tab #6 after tab #2, how can i do it?
I couldn't drag the tab to the location i want! The 5 tabs are full of controls that took long time to name and design. Any idea how to move last tab and place it after 3rd tab?
In order to arrange the tabs in a TabControl, access the property dialog for the TabControl and find the "TabPages" property. Clicking on the little button next to the value field will display a dialog which will allow you to control the properties and position of each tab in the TabControl.

Although an answer is there: I thought this picture may speak few more words ;)
Click on Tab Control
Go to Properties Window
Click on Tab Page as highlighted in blue
Voila! The TabPage Collection Editor allows you to perform what you need. It's intuitive.
I have a WPF tabcontrol with 3 tabs. On the top of the first page is a scrollviewer with a couple buttons which make up a menu of common tasks (save, load etc). I would like this scroll viewer to appear at the top of every tab. Is it possible to do this without simply copying and pasting the code to every tab?
You can make a custom control that contains the UI and logic for the buttons, and then include that control on each tab. The best way to do this is to create a subclass of ScrollViewer, and in the XAML define each of the buttons. On each of your tab pages you can create and create an instance of your new subclass.
This will result in a different instance of your class on each page, but the logic for the buttons will only exist in the code once.
You could implement the scroll viewer and buttons outside and on top of the tabcontrol.
