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;

I am using Devexpress winform for my project. There are three forms simply. The first is MainForm that used MdiParent, the second is FormArticles that used listing articles about law into GridControl. And the last is FormArticleView that used viewing selected article into pdfViewer control. I managed to use documentManager and SplashScreenManager while loading Mdi Child forms and articles into one of Mdi Child form FormArticles. Here is my code:
public prjLibrary()
{
InitializeComponent();
var frm = new FormArticles{ MdiParent = this, Dock = DockStyle.Fill };
frm.Show();
}
While transition one form to another, the forms is fractured and after load it is fixed. Here is my screenshot:
And here is fixed view:
How can I fix fractured view while transition of forms?
This is because when the form from the first screenshot is getting focused, the controls have to be rendered in their Paint-event. This seems to take some time but you can see the fractured text is shown in rectangles where I think the underlying controls (radio buttons, text boxes, labels) are placed. So they are not rendered yet and not ready to go while any other call is blocking the thread. I think the problem is that you create a new form in your mainForm's constructor.
Anyway, it is a good practice to perform heavy tasks (which seem to block the painting of your controls) in a background thread having the UI waiting for the response. If this is too hard to do, try to do it after the UI is shown to the user. This could be the OnLoad- or even OnShown-event.
Note that I don't want to encourage you to write any business code into the UI layer but that seems not to be the question here.
I'm trying to implement some complement views inside my application and I would like to have a better layout control over them. I don't know how to explain in words what my desired functionality is, so I made it through with some photoshop help, hoping you could give me a hand to implement it.
My application now looks like this:
(i need reputation to post images so.. sorry for the links)
http://i59.tinypic.com/2ikv8m1.jpg
When I minimize the modeless form which is focused in the previous image, I would like to be able to see it (and handle it to maximize or close) inside my main form as I show in the image below (made it in photoshop)
http://i58.tinypic.com/1e28go.jpg
Hope someone can lead my into a solution and thanks for the support.
EDIT: I need to be able to move that form outside my main form, even to a different monitor.
If you don't want to use the MDI approach, then set TopLevel of the modeless Form to false and add it to the main Forms Controls collection before showing it:
Form frm = new Form();
frm.TopLevel = false;
this.Controls.Add(frm);
frm.Show();
*Obviously changing Form to the correct type of your modeless form.
If i understand what you are trying to do, you want to minimize a certain form but still see it within your app (im assuming like Excel or Word)
You can do something similar to what Idle_Mind said, but enclose both in a Form instead of the parent.
Form fParent = new Form();
fParent.Dock = DockMode.Fill;//i think this is the syntax. Use this if you want the form to fill to the screen
Form fChild = new Form();
fChild.TopLevel = false;
fParent.Controls.Add(fChild);
fChild.Show();
Here, it should minimize to the lower left part of the parent form. You can then size the parent to whatever you want it to be.
So here's my Question, I'm new to C#(teaching my self at that) Here's the thing, I'm working on a basic sim game, nothing to complex but I've got the design and basic functions done.
However In order to implement it, I'm currently using multiple Forms(Visual Studio 2013)
I have my "main" form which has the "action" buttons to it
So when i want to go to a user Profile page I have
Btn_profileview Click(object sender, EventArgs e){
Form profile = new Form();
profile.Show();
}
The User would then implement the changes(for instance change name) which is written to a text file, for use in other areas of the program.
However It opens a new windows, I've tried modal and nonmodal windows and while the benefit of Modal so they have to actual close the window solves the issue, i'd rather have it just overwrite the preexisting Form, and then on close go back to the "main" screen without actually using multiple windows.
Now I was told UserControl and/or Panel would solve the issue, but it would cause a complete redesign moving from the multiple forms to the multiple panel screens and figuring out how to get those to work(Visible and Invisible), i'm assuming it wouldn't be extremely difficult something along the lines of Panel"name".show(); and panel"name".close();
But would it be possible to actually add a line of code to the pre-existing code(so as not to cause a complete reesign) or are Panels and UserControl the only real way to implement within 1 continuous windows?
paqogomez is right: There are many ways to do it.
Here is one that combines a lot of the pros:
You create an invisible Tab on your window with as many pages as you need. Place a Panel on each tab and create all your controls on of them. This does not mean that you have to do it all over - you can move and drop the controls you already have without much hassle. Of course you need to turn off docking and maybe anchors, but other than that this is a simple process.
If you have controls on the 2nd form with the same name, these names should be changed to something unique though. I hope all Controls have proper names already, but especially Labels get neglected, at least here.. (With a little luck you can even use cut and paste to get Controls from another form to panel2!)
The big pro of this trick is that you can do all work in the designer of the same form. The Tab control serves only as a container where you keep your panels without adding to the UI and without giving the user control of what is shown.
Next you create one Panel variable in your main form:
Panel currentPanel;
On Load you assign the first 'real' Panel to it like this:
currentPanel = panel1;
this.Controls.Add(currentPanel);
Later, each time you want to switch, you re-assign the panels you need like this:
this.Controls.Remove(currentPanel);
currentPanel = panel2; // or whichever panel you want to show..
this.Controls.Add(currentPanel );
If your real panels are docked to fill the tabpage, as they should, the currentPanel will fill the form. You still have access to each panel and to each control by their names at any time but you see no overhead of tabs and your form never changes, except for the full content.
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);
}
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.
