I have a program that when I click the "next" button, another window appears with the same form or other components appear.
I tried to add a panel on the main form with two buttons "home" and "next" and then a panel where you can see other forms to give the feeling that the page is changing. In the constructor I try to pass the previous form and the main one so that when clicked it returns to it with all its elements.
DesktopReserve formPadre;
DesktopPrincipal deskPrincipal;
public Form1(DesktopReserve formPadre, DesktopPrincipal deskPrincipal)
{
InitializeComponent();
this.formPadre = formPadre;
this.deskPrincipal = deskPrincipal;
this.deskPrincipal.returnButton.Click += new System.EventHandler(this.returnButton_Click);
}
I understand that this is not the best way to do it. Apart from the fact that when I show the different forms within this panel it shows in another size, I would like to know a more efficient way to execute this.

I'm trying to make a WindowsFormApplication in Visual Studio 2015 and need some help.
I've been trying to search for the answer on internet but can find out how to do the following:
I have two windows (solutions?). I open the second window with a button in the first one with this code:
this.Hide();
intermec prodinter = new intermec();
prodinter.ShowDialog();
My question is:
How can i "include" the second window (like "include" in PHP) instead of close the first window and then open the next one, like it does now?
A Form is just another Control. Think of it as a Container (because it holds other Controls).
A User Control can also hold more than one Control. There are ways you can display a Window inside another Window in a WinForms app, but the desired effect is not always guaranteed. So it would be best to place all of your controls (for "page 1", for example) in a User Control called "Page1", and then, when appropriate, add that User Control to the Form, and set its Dock property to Fill.
And when it's time to show a different "page", Hide(); "Page1", and Show(); "Page2".
I think you are talking about form inheritance:
Just create a form, lets call it as frmBase. And add some controls onto frmBase which you want to have on other forms as well.
Create other form, lets call it as frmDerived.
In the code behind of frmDerived, just do the following:
// derive the frmDerived form from frmBase
public partial class frmDerived : frmBase
{
public frmDerived()
{
InitializeComponent();
}
}
And then just check the frmDerived form design, it should include everything from frmBase.
And you may want to make the access modifier of some controls of frmBase to Public as required to access them on frmDerived.
I hope this will help you. :)
So I'm trying to learn a thing or two about coding with c# and something i find quite annoying is the way to switch between forms.
Lets say for a game you want to go to the options panel and when you click the button to get there it closes that window(form1) and opens a new window(form2) for my app.
It doesn't look very nice having windows opening and closing like that so I'm wondering what i can do in order to make it switch from form1 to form2 without closing form1 and not open form2 in a new window (Everything switched on the main window(form1).
Might sound a bit confusing but hopefully you understand what i mean.
The code I'm using so far to switch between forms:
ChangeOptions optionchanger = new ChangeOptions ();
this.Hide();
optionchanger.Show();
You could add two panels to a single form, each of which contains the controls you would otherwise have added to one of the two forms. Then switch between the panels by changing their visibility or Z-order. This is slightly tricky in the Windows Forms Designer because you'll have to design the two panels, then position them in the same spot on the containing form.
As #ryanyuyu points out, you can set the Dock property to DockStyle.Fill and switch which panel is on top using Control.BringToFront or Control.SendToBack(). This is also a decent way to interact with the two panels in the designer, as you can switch which is on top from a context menu option.
To truly have two forms, your only option is to show a dialog. Hiding your current window is of course optional.
However, you can:
Group all the controls on a given "form" into a Panel or GroupBox, then show/hide the container control.
Put all the controls into UserControls and have an instance of each UserControl on the main form. You can then show/hide the control.
I prefer the second method as it keeps the encapsulation tighter. Since you already have two forms, its easy to convert to user controls.
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

In Form1 I'm enabling IsMdiContainer and I added a MenuStrip. In Form1_Load I "new" Form2 and I'm assiging Form2.MdiParent to this which is Form1. I'm also maximizing Form2 and this operation works well.
In Form2 I have a treeView on the left side of the form and on the right side of the form I would like to display a number of different forms with various editing capabilities which will be dependent upon the node or level selected in the treeView.
I would like to create a number of different forms for editing data that would be displayed in Form2 depending on the selection from the treeView. I can't seem to add a form to the MdiChild and I've been seeing some posts where adding a form to a form may create some programming problems which I'm not sure about.
I really don't have any code to paste into this post because nothing seemed to work except for the Mdi Parent and Child relationship which was pretty simple.
Thanks in advance for any help.
There is a lot of information on this subject, but some documentation can be difficult to understand for some new developers. Follow these steps:
Open Visual Studio
Create a Windows Form Application
Click your Form
Go to Properties for that Form
Minimum Size : 1366 pixels by 768 pixels.
Launch Maximized
The important element is IsMdiContainer
Open your Toolbox.
Go to Menus
Drag FileMenu onto your Form
Build your Menu
Then go to Solution Explorer
Right-Click Add Item
Add another Form
I left mine as Form2 (In a real program, not a good name).
So within those fifteen steps, we have all that we need to accomplish our goal. So what we will do to finish our task is:
Go back to our First Form
Go to our FileMenu
Double Click on the menu button you wish to link.
It will load a code view, inside the area put this:
Form2 newFrm = new Form2();
newFrm.MdiParent = this;
newFrm.Show();
What this code is doing is three distinct things:
Line 1: It is actually calling our object, in this case a second form. It is actually building our object for us.
Line 2: Is actually linking our second form to our current form, this is physically turning our second form into a Child Form.
Line 3: This is actually physically showing our second form when the button is clicked.
That is all you need to physically show a Form.
In regards to your second question, I'm not entirely sure what your attempting to accomplish. It sounds like your trying to have a tree, then as a Node is selected the right hand side of the Form changes to specific context.
Now this isn't the nicest example, but do you mean something like this?
TreeNode node = treeView1.SelectedNode;
if (node.Text.Contains("XP"))
{
TextBox one = new TextBox();
Panel i = new Panel();
i.Dock = DockStyle.Right;
i.BackColor = Color.Black;
i.Controls.Add(one);
i.Show();
TreeFrm.ActiveForm.Controls.Add(i);
}
Not sure if that is what you are seeking. Obviously you'd want to implement a FlowLayoutPanel to make the positioning not a pain for you. Keep in mind an MDI Parent, with a Child Form acting as a MDI Parent will not work very well. As most things will default to MDI Parent Forms Docking / Positioning. This example is not pretty, but I'm not entirely sure of what your asking.
Are you trying to dock other forms or components on the same form?
lets say i have a main form which have a lot of functionallity.
this form have a tab control in which each tab contain some set of functionality.
what i want to do is when i click on each tab controls button i want to load a form into the client area of the tab control.
so instead of having a lot of controls in the main form , i will only have set of forms and each form will have its control.
i think this is will be better in term of managing the controls so i dont have like 150 control on the main form.
so basically i want to load a form on another form and not show the form in a seperate view.
if its not possible with forms then can i use another control that will group the controls and will be loaded on the main form?
thanks
Alternate 1 :
You can make each of the form as a User Control and then you can load the appropriate user control in a blank panel in your main form whenever required.
You should be able to find a way to communicate between your form and those user controls.
Alternate 2 :
You can show the appropriate Form using ShowModal() method, with the main form as parent, that way user can finish the work with the child form, before coming back to the main form.
Disadvantages here are user wont be able to interact with the main form as long as the child form is closed.
I would recommend looking into User Controls.
User Controls come with a designer, just like forms, and have a rich event model to tap into. Unlike forms, they are easy to embed into other controls and forms. As a matter of fact, user controls will show up in your toolbox to drag-and-drop onto another form.
It's at least worth taking a look at.
Following code adds one Form to a panel in another form.
Add this code in Form1
Form2 ff = new Form2();
ff.TopLevel = false;
ff.Dock = DockStyle.Fill;
ff.ControlBox = false;
ff.Text = "";
panel1.Controls.Add(ff);
ff.Show();
The flip side is your panel should be big enough to accomodate the form...
