so I have a Homepage on one of the TabPages on winform TabControl. I have a button, that adds a new tab using this Tabs.TabPages.Add("Homepage");
But TabPages.Add() just adds a new blank page, how would i clone my HomePage on the new tab? For instance, if my homepage has a button "Click me", when i open a new tab, I want it to have the same button "Click me" linked to the same event "ClickMe_click". Like a Chrome Tab control. I couldn't find any event or method built in for TabControl on msdn, unless i missed it.
Any help or hint or suggestion would be appreciated. Thanks.
You can't clone a tabpage so easily. One can try but the recommended way is:
Create a UserControl and add all the controls you want on your page. Make it Dock=Fill and add any code that connects the controls. You can layout as freely as you would in a form or a tabpage..
Whenever you want another page of this type, add a new tabpage and add an instance of the UserControl to its Controls collection.
Note: All controls on your UserControl by default are private. This is not really different from placing them on the tabpage directly. But now they are private members of the UC class, so your form and its code can't access them.
Looks like a problem when you're new to it. But if you look at it right, it is a good oportunity to create a leaner & cleaner interface.
Solution 1: Change the control modifiers to public as needed
Solution 2: Add properties to expose those data you really want to expose.
Also note: You can do all layout but can do so only in the UC designer. After adding to a form or tabpage there will be no embedded designer..

I just started working with Visual Studio C# and to be honest I didn't fully understand what happens when we chose to hide a form or a user control.
My intuition tells me this hide/show method is kind of "inefficient" way to get an user through all the functions of my app.
So I am asking you guys if there is another workaround to "load" user control parts in a form.
Right now my main_menu form has all the user control objects placed on the form, but hidden, and I am using buttons to show them.
Is there a better way to achieve the same result? (I was thinking of a workaround like having an empty panel where I can load the User Control - not sure if possible)
Thank you!
You can create the controls on the fly and add them to or remove them from the Controls collection. On the class level, define this field
private Control _currentPanel;
You can use a more specific type here, if you are deriving all your panels from a common base type.
Then change the panel with
// Remove previous one.
if (_currentPanel != null) {
Controls.Remove(_currentPanel);
}
// Add new one
_currentPanel = new MyNewPanel();
//TODO: possibly set the panels Docking property to Fill here.
Controls.Add(_currentPanel);
In the example I am working with the form's Controls collection; however, you might have to use the Controls collection of some container control holding the panel.
I am doing my college project onclick event I do not want to open a new form but show the component in the same form by disabling the components of the previous option.
For instance, if I click on ADD button, it will open a new form with details to be added to save.
But, I want to show all those components of ADD form in the same form where click event occurs.
My design is something like, all options will be in left hand side and the result / form with component has to be displayed in the right hand side without opening a new form.
Use Panels.
The Panel Control is a container control to host a group of similar child controls. One of the major uses I have found for a Panel Control is when you need to show and hide a group of controls. Instead of show and hide individual controls, you can simply hide and show a single Panel and all child controls.

Use Panel Control
Add multiple panels one over the other, like a stack.
Either use:
panel1.Visible=false ; panel2.Visible=true on button click
panel1.Enabled=false ; panel2.Enabled=true on button click
according to your design

I have a tab control with tabs on it in a windows application. I have already created some pages. Can I make these pages display on tabs of the tab control?
Thanks in advance.
Make Usercontrols of your pages and add them as TabPages
edit:
To add forms to a TabControl, you will first want to set a Panel inside of a page in the TabControl. Then, do the following in the constructor of the form with the TabControl:
FormToLoad formToLoad = new FormToLoad();
formToLoad.TopLevel = false;
panelInTabPage.Controls.Add(formToLoad);
formToLoad.Show();
You may also want to individually style your forms so that they don't show window chrome.
I have a C# Forms tab application. Each TabPage has a menu on the left (Outlook style navigation panel), and a Panel on the right for content.
If I want the content panel for tab page 0, how would I go about fetching it? I'm a bit stumped because I don't know how to index into the controls collection on a tab page. The following is underlined in red, so I believe its wrong.
Panel panel = tabControl.TabPages[0].Controls["Panel"];
EDIT: remove Window in Panel sub question. It will be moved to a separate question.
Sorry about the beginner questions. I'm a C/C++ guy with lots of MFC time, and C# UI is a bit frustrating at the moment.
foreach (Control control in tabControl1.TabPages[0].Controls)
{
// if (control.Name == "panel1")
}
You can always call this recursively on control.Controls to find a control in any hierarchy. control.Name can be used to find your specific control.
You can't show a Form, inside a Panel. You could create Custom Control where you can add your functionality and add that control to a Panel.
in order to create a new form for example you need to create a variable of what ever form that it is you want to create.
example
Form2 frm2 = new Form2();
frm2.Show();
if you want to show that form in the panel then the panel would be the Owner keep in mind the difference between Owner and Parent
please paste what ever code you have so far and we can suggest the necessary changes
Finally, how does one display a Window in a Panel? - you don't want to do that. If you want a window and a panel to share a piece of UI functionality, create a user control with all the the functionality and then you can place it in a form or in a panel.
A possibility to encapsulate complex UI content is to create a UserControl. This way you can create a reusable piece of complex UI you can basically add as a "blob" inside a form.
The reason why
Panel panel = tabControl.TabPages[0].Controls["Panel"];
is underlined red is because the Controls collection returns a Control which might be a Panel but also might be something else. So you need to cast it:
Panel panel = tabControl.TabPages[0].Controls["Panel"] as Panel;
if (panel != null)
{
// got a panel here so do something
}
Also: MSDN has some good resources - you should make use of it.
I have a bunch of Custom Control Forms (i.e. login page, home page, etc.) that I want to be embedded within a "main form". Every time the user navigates to another page, only the content of the "main form" gets changed.
But the only way I can do this is to copy the contents of the Custom Controls and paste them into the "main form" - which is messy. Is there a standard way of doing this type of thing?
Update:
Ok it sounds like possibly you want to use an MDI form or maybe to use user controls (switching out controls for the new pages and such).
Old:
Is it possible you are talking about ASP.net pages and wanting to use master pages?
You might want to use a Panel. Put all the controls for each “embedded form” in a panel of its own. Then you can just show and hide the right panel to make controls appear and disappear.
Alternatively, if you want the user to be able to manually switch between the “pages”, you could consider using a TabControl.
