TabPages for newly opened Windows Forms C# - c#

I want to add a new tab page for every newly opened form.
Example:
frmReport reportform = new frmReport();
report.Show();
When I open the frmReport form, it must be opened in a new TabPage, as in Windows Internet Explorer 7-8 tabpages.

What you would like to achive here is to have "windows inside tab pages". This is not like it supposed to be! It looks like this:
Windows OS
Windows of applications (Window class)
Containers placed on Window (for example: Panel, TabControl!)
Controls placed on Windows and Containers (for example: Button, but also containers like Panel!)
So when you look on this you see that it's not ok to put Windows class into TabControl!
So what to do?
Create for example UserControl class and move all your controls from Window to this new UserControl. Next place on your Window TabControl nad on one of it's TabPages put this newly created UserControl.
In this way you'll have a good designed UI. Once again: You do not put Window on your TabPage!

In fact U can add Windows.Forms to TabPages you just need to do set
Form.TopLevel = false
and you can add it to any container be it TabPage or Panel

i used DevExpress Controls for tabPages.

Sorry, there is no direct way to do it. Better to go with Usercontrols instead of Forms and Add controls to the Tab Page.

WPF Workaround to add Window control as a child of visual

I have a requirement to add a Window control inside a panel.
Of course this doesn't seem possible:
Window must be the root of the tree. Cannot add Window as a child of Visual.
The problem boils down to drawing the Window Chrome (control box, title bar, minimize/restore/close button and borders) inside a panel using the OS theme configured by the user. Are there any workarounds I should be investigating?
This is what User Controls are for - creating controls that can be reused in multiple windows. Refactor your Window Control so that it is just a Window that contains a single User Control (which in turn contains everything your window previously had). Place the User Control in your Panel. The idea is that your current window (that you want to be a child, we'll call it Window B) looks something like this:
Window B -> Grid/Panel -> Other Controls
And should instead look like this
Window B -> Grid/Panel -> User Control B -> Grid/Panel -> Other Controls
And now other other window can look like this:
Window A -> Grid/Panel -> ... -> Panel -> User Control B
If you're trying to achieve an MDI like interface, you have a few options - use tab controls, use a panel that can be dragged and/or resized, etc. In this case, you would still want a User Control, so that it could easily be reused in different windows (or panels) that you create, especially if you end up having to create those panels programatically (e.g. if you intend to create multiple instances dynamically at runtime).
In this case, you'll probably want two user controls: one that has all the controls from your other window, and one that would act as a "window" control within your main window. The "Window" control would have functionality for resizing, docking, etc.
WPF does not support creating a window as if it were a control, or as a child of another window (the closest you can get to that is having a window be shown as a modal dialog).
As the only answer is completely off topic, here is the best answer I can come up with:
Create window, render window as Bitmap, put bitmap inside panel.

How to show multiple form pages in single windows form application?

I have got a requirement to design a windows forms application using Visual Studio 2010.
According to the design I have to develop the application which contains a menu bar. On selecting of the menus from the Menu bar relevant forms should open. Now as per my requirement these menu forms should be displayed in the same parent Windows Form. Means everything should be in the single form Application.Nothing should be out of that.
The problem that I'm facing is that I don't know how to proceed with this. This is the first time I'm working on Windows Form Application leaving Web.
You are looking for developing an MDI application. MSDN article to guide you - http://msdn.microsoft.com/en-us/library/xyhh2e7e(v=vs.100).aspx
You could build a grid area on your form using a combination of split containers (horizontal and vertical).
Then in separate panels design each of your menu forms, with each panel visibility set to false.
When choosing a menu you would need to assign a parent (split container panel) to the menu form and set it to visible.
Step 1
Create a form and give the name it to "mdiMain" and set the property IsMdiContainer to true.
Add a MenuStrip control from the ToolBar and add some menues.
Step 2
Create another form and give the name it to "frmChild"
Step 3
Write some code in menu click event to display frmChild form in MDI Parent.
Dim frm As New frmChild()
frm.MdiParent = Me
frm.Show()
Now your application is ready. You can place your code and control in frmChild window form.
As an option in some cases you can use WebBrowser control and manipulate html code inside depending on the menu bar selection.

C# make each panel in a separate view

I would like to know how I could possibly modulate my views in an application. Let me explain.
Instead of building my view and adding all the components in one screen. I want to say put each panel in its own class / form and then have a main form where I can add and remove these 'modular' panels.
Is this possible and how would I go about doing it?
In Windows Forms there is the concept of an empty component called UserControl, that can be freely designed and added at any time to another component or form container. UserControls are used very often in order to create flexible and exchangable UI. You can create a UserControl item in Visual Studio like this:
Name the new control:
After that you can design your UI control:
When your are done with the design, compile your project/solution and go to the form where you want to add your newly designed control. In the toolbar panel you will see your new UserControl, which can be added to the form with drag & drop (with the mouse):
You can create as many UserControls as you want and add/remove them to/from your form.
All of this steps can be done completely in the code. In order to create new view of this kind, you need to create a new class that inherits the predefined UserControl class:
public class EditorUserControl : UserControl
{
}
Every Control element has a ControlsCollection that holds/contains components of type Control that are drawn when the UI is shown. In order to add your new control to the main panel you need to add it to the controls collection:
public partial class EditorUserControl : UserControl
{
public EditorUserControl()
{
var button = new Button();
button.Text = "Import";
this.Controls.Add(button);
}
}
Note, that when adding components manually, you are responsible for sizing and position them. Predefined layout panels can help you here:
TableLayoutPanel - layout with cells
SplitPanel - horizontal or vertical predefined resizable panels
etc.
Now all that left is to add the new user control to the main form just like you added the UI elements to your own control:
var simpleEditor = new EditorUserControl();
simpleEditor.Dock = DockStyle.Fill;
this.Controls.Add(simpleEditor);
You can adjust the UI control settings through its predefined properties.
You can mix predefined containers and UserControls in order to achieve the desired UI:
There are a lot of good beginners tutorials for C# and VS and .NET:
Channel9 tutorials
MSDN Visual Studio UI tutorials
Composite UserControl tutorial
Developing with Windows Forms Documentation and Examples
This is definitely possible. I will use WinForms but there are similar ways in WPF such as frames.
In WinForms you can create a new User Control for each 'modular' panel which will automatically create .cs and .designer.cs files just like in a normal Form. You can then add logic and functionality to the panels as if they were forms themselves. All that would then remain is to add the logic to the form to load the default panel on startup and think of ways of how other panels can be brought into view (e.g. a next button or having a panel on each tab in a tab control). Showing a panel in a form (or any other user control for that matter) is achieved by creating an instance of your desired panel and adding it to you form/control's Controls property like so:
public Form1()
{
InitializeComponent();
MyPanel panel = new MyPanel();
this.Controls.Add(panel);
}

Is their something like iframe in C#?

Is their something like iframe in c#?
I want to build an application with one form that its content changes according to the actions I do, like messenger live. The part when I log in and log out its too different "windows" but it happens in the same form.
There is no iframe equivalent in winforms or wpf, but there are ways to deal with it.
For either winforms or wpf, what you want to do is have a Panel which you change the content of.
A panel is a container which holds/encapsulates other controls.
If you have two different views you want to toggle between, create two panels at the same position with the content you need. Then you will show one and hide the other. When the user executes some action which requires you to change the view, then simply hide the displaying panel, and unhide/show the other one.
Think of it as layers, where you will only show one at a time.
You can also dynamically load user controls into a panel, much like an iframe, but I find it easier to have the content in the form, and hide/show as needed.
Assuming WinForms, how about using UserControls? Place as many as you want in a single/multiple forms, and interact as you do in forms. See, UserControl class.
You can load a form into a Panel or tabPage from a TabControl:
Form f = new Form();
f.TopLevel = false;
panel1.Controls.Add(f);
f.Show();
f.Dock = DockStyle.Fill;

What is the standard way to add controls to a TabPage at Design Time?

I am creating my first Windows Forms application, to be deployed on Windows Mobile and I am having some trouble designing a Tabbed Interface.
I had assumed that I could Create a TabControl, then Add some TabPages and then drag Controls on to each Tab Page in turn. This does not appear to be possible and most of the information I see on the web seems to suggest that the controls should be added dynamically at run-time.
Am I missing something obvious here or is this indeed correct?
If you do have to add the controls at runtime then how do people generally manage the design process. Do they create a Custom UserControl for each tab and then add that at runtime?
Design environment (C# Visual Studio 2005, .net 2.0)
Runtime environment (Windows Mobile 6.1)
Update 1
The actual steps taken within visual studio were as follows :-
Select New Project -> SmartDevice -> Windows Mobile 6 Professional -> Device Application
Added a TabControl to Form1. This automatically adds tabPage1 and tabPage2
Update 2
The solution to this is embarrassingly noobish. The TabControl puts the tabs at the bottom of the page, the first thing I was doing was resizing the tab control to a single line which was then hiding the TabPage control.
Currently i don't use Windows Mobile, but i think it works quite the same.
After adding a TabControl to your form you should take a look into the properties and search for TabPages. Here you can add and delete new TabPages to your Control and design it as you like in the designer.
To your question about using UserControls on each TabPage i would definitely say Yes. It makes easier to separate between each page and what will happen on each one.
Also at a last step i am going to move the needed code out of the Designer.cs into my own function (e.g. var tabControl = CreateTabControl() where all of my properties are set. Then i put all my UserControls into an
private IEnumerable<Type> GetAllTypes()
{
yield return typeof(MyFirstControl);
yield return typeof(MySecondControl);
}
and make an
private void CreateTabPages(TabControl tabControl, IEnumerable<Type> types)
{
foreach(var type in types)
{
var control = Activator.CreateInstance(type);
var tabPage = new TabPage();
tabPage.Controls.Add(control);
tabControl.TabPages.Add(tabPage);
}
}
this will then be called by
CreateTabPages(tabControl, GetAllTypes());
With this approach i can easily add another Tab Page with a single line of code and design it in its own scope.
I just opened vs2008 and created a tabcontrol, then I added controls inside using drag and drop in the designer and I didn't found any problem.
The way I use to do it is to create a usercontrol for each tab, But I add the usercontrol to the tab in the designer. (note that the usercontrol will not appear in the toolbox until you generate your solution).
I didn't know why your method are not working. Did you stop your application before try to add the controls?
Good Luck.
