How can I use a textbox, label and button that was added to a panel to input and show information

Okay so basically I have a calendar display and when you click on anyone of the dates on it, it creates a new panel with a label displaying the date selected. I also made it so when you click on a date and a new panel is made, a label, textbox and button is created and placed onto that new panel as well.
So what I want and have been struggling with is for me to enter something into that textbox then to press the button to submit it and then for it to show on the label.
I think I know what the issue is but I've been stuck at this for hours.
Here is my code:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void monthCalendar1_DateSelected_1(object sender, DateRangeEventArgs e)
{
Panel newPanel = new Panel();
this.Controls.Add(newPanel);
newPanel.Visible = true;
newPanel.Size = new Size(564, 831);
newPanel.Location = new Point(0, 190);
newPanel.BringToFront();
Label textLabel = new Label();
textLabel.Size = new Size(500, 500);
textLabel.Font = new Font(textLabel.Font.Name, 25, textLabel.Font.Style);
textLabel.Location = new Point(3, 3);
Label dateLabel = new Label();
dateLabel.Size = new Size(500, 500);
dateLabel.Font = new Font(dateLabel.Font.Name, 25, dateLabel.Font.Style);
dateLabel.Location = new Point(128, 3);
Button Submitbutton = new Button();
Submitbutton.Location = new Point(100, 500);
Submitbutton.Text = "Add Food";
Submitbutton.Size = new Size(400, 100);
Submitbutton.BackColor = Color.Aqua;
Submitbutton.BringToFront();
Submitbutton.Click += Button_Click;
TextBox textBox = new TextBox();
textBox.Location = new Point(100, 650);
textBox.Size = new Size(500, 500);
textBox.BackColor = Color.Aqua;
textBox.Visible = true;
textBox.Text = "Enter food here...";
textBox.BringToFront();
Label inputtedFood = new Label();
inputtedFood.Size = new Size(500, 500);
inputtedFood.Font = new Font(inputtedFood.Font.Name, 25, inputtedFood.Font.Style);
inputtedFood.Location = new Point(100, 600);
inputtedFood.Text = "placeholder";
newPanel.Controls.Add(dateLabel);
newPanel.Controls.Add(textLabel);
newPanel.Controls.Add(Submitbutton);
newPanel.Controls.Add(textBox);
newPanel.Controls.Add(inputtedFood);
String myCalendar = monthCalendar1.SelectionRange.Start.ToShortDateString();
textLabel.Text = "Date:";
dateLabel.Text = myCalendar;
}
private void Button_Click(object sender, EventArgs e)
{
inputtedFood.Text = textBox.Text;
}
private void monthCalendar1_DateChanged_1(object sender, DateRangeEventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
}
}
I tried the above code and was met with errors that are shown in the post.

Totally agree with both LarsTech and Ňɏssa Pøngjǣrdenlarp, you should be building a UserControl in place of the Panel and placing the TextBox, Button, and Label inside of that.
Your immediate question, though:
So what I want and have been struggling with is for me to enter
something into that textbox then to press the button to submit it and
then for it to show on the label.
Can be accomplished with this simple code:
Button Submitbutton = new Button();
// ... more code ...
Submitbutton.Click += (s2, e2) =>
{
inputtedFood.Text = textBox.Text;
};
Here's a little example showing it in action:
private void button1_Click(object sender, EventArgs e)
{
FlowLayoutPanel flp = new FlowLayoutPanel();
TextBox textBox = new TextBox();
// ... more code ...
Label inputtedFood = new Label();
inputtedFood.Text = "placeholder";
// ... more code ...
Button Submitbutton = new Button();
// ... more code ...
Submitbutton.Click += (s2, e2) =>
{
inputtedFood.Text = textBox.Text;
};
flp.Controls.Add(textBox);
flp.Controls.Add(Submitbutton);
flp.Controls.Add(inputtedFood);
flowLayoutPanel1.Controls.Add(flp);
}
The output:

I am making a chat app in c# wpf and it is doing something strange

So basically i just add a label to a panel once i get a message and im tracking the y axis of the previous message and im adding 35 to it every time a new message is detected and i use that variable as the y axis for each label, it worked fine so far but after i added a scroll bar it is acting wierd, the numbers are as i expected, but the messages are put so far apart its hard to see.

prompt.Width = 500;
prompt.Height = 200;
prompt.Text = "Enter a nickname";
Label textLabel = new Label() { Left = 50, Top = 20, Text = "Nickname: " };
TextBox inputBox = new TextBox() { Left = 50, Top = 40, Width = 400 };
Button confirmation = new Button() { Text = "Ok", Left = 350, Width = 100, Top = 70 };
confirmation.Click += (sender, e) => { prompt.Close(); };
prompt.Controls.Add(confirmation);

How to assign Tab Pages dynamically and add a single text box to store the data from text box into the database using c#

So I am creating forms using Visual Studio .NET.
I am stuck when I try to add tab pages dynamically on a button click which creates a text box in a new tab.
When I create multiple tabs I want to get the data from the text boxes of each newly created tabs and add it to the database. I am having problems as these text boxes have the same name as I create them dynamically. I am new to C# and I need help.
public void add()
{
aa.Add(txt.Text);
var a = 1;
var newTabPage = new TabPage()
{
Text = "Page"
};
txt = new System.Windows.Forms.TextBox();
this.tabControl1.TabPages.Add(newTabPage);
newTabPage.Controls.Add(this.txt);
System.Windows.Forms.Label lbl = new System.Windows.Forms.Label();
newTabPage.Controls.Add(lbl);
lbl.Text = "New";
txt.Name = "Get";
lbl.AutoSize = true;
lbl.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Underline, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
lbl.Location = new System.Drawing.Point(7, 389);
lbl.Name = "label263";
lbl.Size = new System.Drawing.Size(871, 13);
lbl.TabIndex = 317;
lbl.Text = "AA";
newTabPage.Controls.Add(lbl);
}
private void txt_TextChanged(object sender, EventArgs e)
private void button1_Click_1(object sender, EventArgs e)
{
add();
string value = txt.Text;
aa.Add(value);
}
private void saveToolStripMenuItem2_Click(object sender, EventArgs e)
{
SqlCommand command;
string insert1 = #"insert into testing(test) values(#testingt)";
using (SqlConnection conn = new SqlConnection(connectionString))
{
try
{
conn.Open();
for(int i= 0;i<aa.Count;i++)
{
if (aa[i]!= "" && aa[i]!="New Box")
{
command = new SqlCommand(insert1, conn);
command.Parameters.AddWithValue(#"testingt", aa[i]);
command.ExecuteNonQuery();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Maybe you can set the Name property to distinguish them when you create them by creating an increment variable.
int pagecount = 1;
private void btAddtab_Click(object sender, EventArgs e)
{
TabPage tabPage = new TabPage
{
Name = "Tabpage" + pagecount.ToString(),
Text = "Tabpage" + pagecount.ToString()
};
TextBox textBox = new TextBox
{
Name = "TextBox" + pagecount.ToString()
};
tabPage.Controls.Add(textBox);
tabControl1.TabPages.Add(tabPage);
pagecount++;
}
As for how to get the value of the specified TextBox, you can refer to the following code.
private void btGetValue_Click(object sender, EventArgs e)
{
foreach (TabPage page in tabControl1.TabPages)
{
foreach (Control control in page.Controls)
{
// get the first textbox's value
if (control is TextBox && control.Name == "TextBox1")
{
Console.WriteLine(((TextBox)control).Text);
}
}
}
}

Create Button at runtime and save it permanently in c#

I have this code to create a button:
private void CreateButton(){
Button createButton = new Button();
// Set Button properties
createButton.Height = 40;
createButton.Width = 300;
createButton.BackColor = Color.Red;
createButton.ForeColor = Color.Blue;
createButton.Location = new Point(20, 150);
createButton.Text = "I am Button";
createButton.Name = "Button";
createButton.Font = new Font("Georgia", 16);
createButton.Click += new EventHandler(create_Button_Click);
this.Controls.Add(createButton);
}
private void create_Button_Click(object sender, EventArgs e)
{
MessageBox.Show("button is clicked");
}
and i want to save it permanently in the project. what is the best way to do this?

How to host datetimepicker in DataGridView control in C# winforms

private void showdate(DataGridViewCellEventArgs e)
{
dateTimePicker1.Size = vacation_transDataGridView.CurrentCell.Size;
dateTimePicker1.Top = vacation_transDataGridView.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true).Top + vacation_transDataGridView.Top;
dateTimePicker1.Left = vacation_transDataGridView.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true).Left + vacation_transDataGridView.Left;
if (!(object.Equals(Convert.ToString(vacation_transDataGridView.CurrentCell.Value),"")))
{
dateTimePicker1.Value = Convert.ToDateTime(vacation_transDataGridView.CurrentCell.Value);
//dateTimePicker1.Visible = false;
}
dateTimePicker1.Visible = true;
}
This code in dgv cell_click event

There is an example of exactly this thing on MSDN.
http://msdn.microsoft.com/en-us/library/7tas5c80.aspx

Unfortunately there isn't such a Cell or Column Type you can use (as far as i know). But Microsoft provides an example on how to get a NumericUpDown (that also doesn't exist) into a DataGridView.
Maybe you can adopt this example to get your DateTimePicker into a DataGridView.

private void dgtest_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex == 0)
{
dtp = new DateTimePicker();
dgtest.Controls.Add(dtp);
dtp.Format = DateTimePickerFormat.Short;
Rectangle Rectangle = dgtest.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex, true);
dtp.Size = new Size(Rectangle.Width, Rectangle.Height);
dtp.Location = new Point(Rectangle.X, Rectangle.Y);
dtp.CloseUp += new EventHandler(dtp_CloseUp);
dtp.TextChanged += new EventHandler(dtp_OnTextChange);
dtp.Visible = true;
}
}
private void dtp_OnTextChange(object sender, EventArgs e)
{
dgtest.CurrentCell.Value = dtp.Text.ToString();
}
void dtp_CloseUp(object sender, EventArgs e)
{
dtp.Visible = false;
}
