How to put GroupBoxes next to each other

I have dynamically genereted group box with label inside
int dlugoscChuja = 0;
string przedmiot = "";//random strings
for (int i = 0; i < 5; i++)
{
GroupBox g = new GroupBox();
g.AutoSize = true;
g.Visible = true;
g.AutoSizeMode = AutoSizeMode.GrowAndShrink;
var lb = new Label();
lb.AutoSize = true;
lb.Location = new Point(6, 16);
lb.Text = przedmiot;
g.Controls.Add(lb);
dlugoscChuja += lb.Width;
if (i != 0)
{
g.Location = new Point((i*(g.Width+g.Padding.Size.Width)-100), 12);
}
else
{
g.Location = new Point(0, 12);
}
this.Controls.Add(g);
}
how i can put those group boxes next to each other?
my kod (i*(g.Width+g.Padding.Size.Width)-100) of course does not work, is there eany proffesional way to place them? If my labels text is longer of course my group box have more width

You can use Flowlayoutpanel inside your groupbox
We can set the direction of items in Flowlayoutpanel to
TopDown
LeftToRight
RightToLeft
BottomUp
Instead of adding labels to groupBox add it to FlowLayoutpanel
//groupbox must outsideloops
GroupBox g = new GroupBox();
g.AutoSize = true;
g.Visible = true;
g.AutoSizeMode = AutoSizeMode.GrowAndShrink;
var flowPanel;
for (int i = 0; i < 5; i++)
{
flowPanel = new FlowLayoutPanel();
flowPanel.Size = g.Size; // set size of flowpanel to groupbox
flowPanel.Dock = DockStyle.Fill; // Fill parent size
flowPanel.FlowDirection = FlowDirection.TopDown;//Use above directions
var lb = new Label();
lb.AutoSize = true;
lb.Location = new Point(6, 16);
lb.Text = przedmiot;
flowPanel.Controls.Add(lb);//lb your labe
}
g.Controls.Add(flowPanel);//finally add flowpanel to groupbox
this.Controls.Add(g);

Windows Forms C# Dynamic controls problem

I'm trying to make a form where the user can add group boxes with other controls inside.
groupboxes and other controls are all created dynamically.
Program image. *the button "Adicionar Pergunta" adds a new group box
Inside the groupbox is a combobox where the user can choose the preset of controls inside the groupbox.
each preset have different controls or controls in different locations of the group box.
my problem is that when the user change the preset of one groupbox all the other combobox stop working.
Here is the my script:
Variables:
int groupboxcount = 2;
RadioButton rb1 = new RadioButton();
RadioButton rb2 = new RadioButton();
TextBox tx1 = new TextBox();

How to set different events for dynamically created element

Im trying to create event with different index for dynamically created GroupBox. With my actual code event for every groupbox is that same. How can i make event with different index for every groupbox? My Code:
public void LoadGry()
{
// GroupBox groupbox = new GroupBox();
Label nazwagry = new Label();
for(int i = 0; i < myCollection.Count; i++)
{
GroupBox groupbox = new GroupBox();
groupbox.Text = myCollection[i];
groupbox.Size = new Size(290, 131);
groupbox.Location = new Point(6, 150 * (myCollection.Count - i - 1));
groupbox.ForeColor = Color.White;
Label label1 = new Label();
label1.Text = groupbox.Text;
label1.AutoSize = true;
label1.Location = new Point(groupbox.Location.X + 80, groupbox.Location.Y + 20);
groupbox.Controls.Add(label1);
Gry.Controls.Add(label1);
PictureBox picturebox = new PictureBox();
picturebox.Location = new Point(groupbox.Location.X + 5, groupbox.Location.Y + 20);
picturebox.Size = new Size(75, 75);
picturebox.SizeMode = PictureBoxSizeMode.StretchImage;
picturebox.LoadAsync(myCollection3[i]);
groupbox.Click += new EventHandler(delegate {groupboxclick(groupbox, picturebox, i);});
Label label2 = new Label();
label2.Text = "Status: " + "Aktualny";
label2.ForeColor = Color.Green;
label2.AutoSize = true;
label2.Location = new Point(label1.Location.X, label1.Location.Y + 20);
Gry.Controls.Add(label2);
Label zapiszopis = new Label();
zapiszopis.Text = myCollection4[i];
zapiszopis.Visible = false;
Gry.Controls.Add((Control)groupbox);
//MessageBox.Show("pokaz mi wysokosc");
}
}
private void groupboxclick(GroupBox groupbox, PictureBox picturebox, int itest)
{
groupbox.ForeColor = Color.Aqua;
this.pictureBox1.BackgroundImage = picturebox.BackgroundImage;
opishacka.Text = myCollection4[itest];
}

The problem is that the event setup is using the variable K value. For use the number instead you probably needs to create an expression manually to use the current value in each case.
BUT
You can easily do what you want using the following properties to attach values to controls.
1-) Tag in WinForms & WPF:
// Setup
pictureBox.Tag = i;
// Event
int i = (int) pictureBox.Tag;
2-) ViewState in WebForms
// Setup
ViewState[pictureBox.UniqueID] = i;
// Event
int i = (int) ViewState[pictureBox.UniqueID];
You can use many other techniques. I only post one for each popular framework. I guest that you are in a WinFors project.
Hope this help!

Restrict the numbers of controls in a winform

i have a button in my form and for every button click it is adding groupBox. but i want a winform contain only 8 groupboxes. when the numbers of groupBox reach 8 it will automatically do Visible=false all 8 before groupBox and again adds a groupBox named(groupBox9). what must i do?
private void butonYeni_Click(object sender, EventArgs e)
{
//creating Font
Font font = new Font("Microsoft Sans Serif", 10.0f, FontStyle.Bold);
Font font2 = new Font("Microsoft Sans Serif", 9.0f, FontStyle.Bold);
int sayGB = 0;
foreach (Control c in this.Controls)
{
if (c.GetType() == typeof(GroupBox))
{
sayGB++;
}
for (int i = sayGB; i < 1000; i++)
{
//creating groupbox
GroupBox Group = new GroupBox();
Group.Width = 767;
Group.Height = 179;
Group.Text = "Soru & Cevap";
Group.Font = font;
Group.ForeColor = Color.Maroon;
Group.Location = new Point(200,66);
//creating label
Label Soru = new Label();
Soru.Text = "Soru: ";
Soru.Font = font2;
Soru.ForeColor = Color.Maroon;
Soru.Location = new Point(6,33);
Soru.Width = 53;
Soru.Height = 13;
//creating textbox
TextBox soruText = new TextBox();
soruText.Width = 685;
soruText.Height = 20;
soruText.Font = font2;
soruText.ForeColor = Color.Black;
soruText.Multiline = true;
soruText.Location = new Point(70,31);
//creating label
Label Cevap = new Label();
Cevap.Text = "Cevap:";
Cevap.Font = font2;
Cevap.ForeColor = Color.Maroon;
Cevap.Location = new Point(6, 92);
Cevap.Width = 53;
Cevap.Height = 25;
//creating textbox
TextBox cevapText = new TextBox();
cevapText.Width = 685;
cevapText.Height = 69;
cevapText.Font = font2;
cevapText.ForeColor = Color.Black;
cevapText.Multiline = true;
cevapText.Location = new Point(70,67);
//creating button
Button btn = new Button();
btn.Width = 75;
btn.Height = 25;
btn.Text = "Kaydet";
btn.BackColor = Color.Maroon;
btn.Font = font2;
btn.ForeColor = Color.White;
btn.Location = new Point(682,148);
//kontrolleri ekleme
Group.Controls.Add(btn);
Group.Controls.Add(Soru);
Group.Controls.Add(soruText);
Group.Controls.Add(Cevap);
Group.Controls.Add(cevapText);
this.Controls.Add(Group);
}
}
}

define an integer class variable and increase it everytime the button is clicked. After increasing it, check if it's greater than 8. If it is, set your stuff to Visible = false.
Mock up:
public class MyClass
{
private int groupboxCounter = 0;
public MyClass()
{
}
private void btn_click(...)
{
// add a new groupbox here
groupboxCounter++;
if (groupboxCounter > 8)
{
//make stuff invisible here
}
}
}

Button_click event(in code) for every button in multiple GroupBox

I have multiple groupbox, which one contains a question and some answers and button ANSWER in each GroupBox. I create GroupBox and its Controls in Form_Load Method, not manually. How to handle button_click events for every button? I think it's not necessary to write this handle method for every button, because there are only two different button_handler: for questions where there can be only one correct answers, and for questions, where multiple answers can be correct.
My questions look like:
My GroupBox structure:
int loc = 20;
for (int i = 0; i < 10; i++)
{
GroupBox gb = new GroupBox();
gb.Name = "GroupBox" + (i + 1);
gb.Size = new Size(500, 200);
gb.Location = new Point(40, loc);
gb.BackColor = System.Drawing.Color.Aquamarine;
Label q_text = new Label(); // текст питання
q_text.Name = "label" + (i + 1);
q_text.Text = "Питання" + (i + 1);
q_text.Font = new Font("Aria", 10, FontStyle.Bold);
q_text.Location = new Point(10, 10);
gb.Controls.Add(q_text);
int iter = q_text.Location.Y + 30;
if (i <= 5)
{
foreach (string key in questions[i].answers.Keys)
{
RadioButton rb = new RadioButton();
rb.Text = key;
rb.Size = new Size(120, 25);
rb.Location = new Point(q_text.Location.X + 10, iter);
iter += 30;
gb.Controls.Add(rb);
}
}else
if (i > 5)
{
foreach (string key in questions[i].answers.Keys)
{
CheckBox rb = new CheckBox();
rb.Text = key;
rb.Size = new Size(120, 25);
rb.Location = new Point(q_text.Location.X + 10, iter);
iter += 30;
gb.Controls.Add(rb);
}
}
Button b = new Button();
b.Name = "button" + (i + 1);
b.Text = "Answer";
b.Location = new Point(gb.Size.Width - 120, gb.Size.Height - 30);
gb.Controls.Add(b);
this.Controls.Add(gb);
loc += 200;
}

You can create a general click event for your buttons:
Button b = new Button();
b.Name = "button" + (i + 1).ToString();
b.Click += b_Click;
and in the method, examine the sender to see which button was clicked:
void b_Click(object sender, EventArgs e) {
Button b = sender as Button;
if (b != null) {
GroupBox gp = b.Parent as GroupBox;
int bIndex = Convert.ToInt32(b.Name.Substring(6)) - 1;
MessageBox.Show(string.Format("I'm clicking {0}, question index #{1}",
gp.Name, bIndex));
}
}
After that, you would have to examine the checked values of your GroupBox child controls with the allowable answers in the questions[bIndex].answers variable.
