Method to create and change label - c#

I want to create label and set the text using method but it wont work, here's my code:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
intro();
}
private void fullScreen()
{
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Bounds = Screen.PrimaryScreen.Bounds;
}
private void intro()
{
pictureBox1.BackColor = Color.White;
pictureBox1.SendToBack();
Label introInfo = new Label();
introInfo.Font = new Font("century gothic", 24, FontStyle.Bold);
introInfo.ForeColor = Color.Cyan;
introInfo.Text = "succes bro!";
introInfo.Visible = true;
introInfo.Location = new Point(100, 100);
}
}
What should I do to make it work?

You need to add the label to the form
this.Controls.Add(label);
Take a look at this example
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.Load += Form1_Load;
}
void Form1_Load(object sender, EventArgs e)
{
intro();
}
private void fullScreen()
{
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Bounds = Screen.PrimaryScreen.Bounds;
}
private void intro()
{
Label introInfo = new Label();
introInfo.Font = new Font("century gothic", 24, FontStyle.Bold);
introInfo.ForeColor = Color.Cyan;
introInfo.Text = "succes bro!";
introInfo.Visible = true;
introInfo.Location = new Point(100, 100);
introInfo.Height = 35;
introInfo.Width = 250;
this.Controls.Add(introInfo);
}
}

You need to add newly created label to the control collection
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
intro();
}
private void fullScreen()
{
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Bounds = Screen.PrimaryScreen.Bounds;
}
private void intro()
{
pictureBox1.BackColor = Color.White;
pictureBox1.SendToBack();
Label introInfo = new Label();
introInfo.Font = new Font("century gothic", 12, FontStyle.Bold);
introInfo.ForeColor = Color.Cyan;
introInfo.Text = "succes bro!";
introInfo.Visible = true;
introInfo.Location = new Point(75, 23);
introInfo.Size= new Size(100,100);
this.Controls.Add(introInfo);
}

Winform UserControl update while not visible

I have a tabControl in a Winform application. The user is able to change settings that will impact each tab visually, and I need to get each tabs as images.
I'm trying to understand why/how some controls are updating even if not visible and some other don't.
Is there a way to force an existing UserControl to update/redraw even if not visible so that Control.DrawToBitmap(...) gets a valid image?
I created an example with a Chart and a FlowLayoutPanel to explain what I mean and to make sure I could reproduce the issue I have.
In the example below:
The image created from the FlowLayoutPanel is only correct if it was updated and visible before DrawToBitmap is called.
The image from the Chart is alway up to date even if updated when not visible.
Questions:
How does it work with one control and not the other?
How could I ensure the FlowLayoutPanel has the same behavior as the Chart?
(EDIT) I have tried a few things without success:
Suspend/Resume layout when updating
call Refresh / Update / Invalidate on the layout that do not update as expected
Here is a gif showing that the chart get updated even when not visible but not the FlowLayoutPanel:
Here is the code of this example:
using LiveChartsCore.SkiaSharpView;
using System.Collections.ObjectModel;
namespace WinFormsDrawToBitmapTest
{
public partial class Form1 : Form
{
int legendCount = 1;
ViewModel viewModel;
public Form1()
{
InitializeComponent();
viewModel = new ViewModel();
cartesianChart1.Series = viewModel.Series;
updateLegend(this.flowLayoutPanel1);
}
private async void button1_Click(object sender, EventArgs e)
{
Bitmap bitmap = await Task.Run(() => getImg3());
this.pictureBox1.Image = bitmap;
this.pictureBox1.Invoke((MethodInvoker)delegate
{ this.pictureBox1.Image = bitmap; });
}
private Bitmap getImg3()
{
Bitmap bitmap = new Bitmap(this.cartesianChart1.Width, this.cartesianChart1.Height + this.flowLayoutPanel1.Height);
Bitmap chart = new Bitmap(this.cartesianChart1.Width, this.cartesianChart1.Height);
Bitmap legend = new Bitmap(this.flowLayoutPanel1.Width, this.flowLayoutPanel1.Height);
this.cartesianChart1.Invoke((MethodInvoker)delegate
{
this.cartesianChart1.DrawToBitmap(chart, new Rectangle(new Point(0, 0), this.cartesianChart1.Size));
});
this.flowLayoutPanel1.Invoke((MethodInvoker)delegate
{
this.flowLayoutPanel1.DrawToBitmap(legend, new Rectangle(new Point(0, 0), this.flowLayoutPanel1.Size));
});
using (Graphics g = Graphics.FromImage(bitmap))
{
g.DrawImage(legend, 0, 0);
g.DrawImage(chart, 0, legend.Height);
}
return bitmap;
}
private void button2_Click(object sender, EventArgs e)
{
Random r = new Random();
viewModel.Data.Add(r.Next(0, 10));
legendCount++;
updateLegend(this.flowLayoutPanel1);
}
private void updateLegend(FlowLayoutPanel flow)
{
flow.Controls.Clear();
Color[] colorList = new Color[]
{
Color.FromArgb(15, 1, 215),
Color.FromArgb(255, 0, 0),
Color.FromArgb(0, 176, 80),
Color.FromArgb(112, 48, 160)
};
for (int i = 0; i < legendCount; i++)
{
//flow.Controls.Add(new LegendLabel($"Label {i}", colorList[i % colorList.Length]));
Button btn = new Button();
btn.Name = $"Button {i}";
btn.TabIndex = 0;
btn.Text = $"Button {i}";
flow.Controls.Add(btn);
}
}
}
public partial class ViewModel
{
public ObservableCollection<double> Data { get; set; }
public List<LineSeries<double>> Series { get; set; }
public ViewModel()
{
Data = new ObservableCollection<double>();
Data.Add(1); Data.Add(2); Data.Add(5); Data.Add(4);
Series = new List<LineSeries<double>>();
Series.Add(new LineSeries<double> { Values = Data, Fill = null });
}
}
}

Creating class that generate labels

I have a problem creating a class that generates labels with specific weight and height, it works on the code, but doesn't show up on the form when I create the object. how I can solve this problem guys?
class cub
{
public int cubWeight = 150;
public int cubHeight = 150;
public void createNewCub()
{
Label cubLabel = new Label();
cubLabel.Size = new Size(cubWeight, cubHeight);
cubLabel.Text = "GeeksforGeeks";
cubLabel.Location = new Point(500, 200);
cubLabel.Font = new Font("Calibri", 18);
cubLabel.ForeColor = Color.Green;
cubLabel.Padding = new Padding(6);
}
}
public Form1()
{
InitializeComponent();
label1.Text = "Number of cubs: " + trackBar1.Value;
label2.Text = "Number of seconds: " + trackBar2.Value;
cub xxx = new cub();
xxx.createNewCub();
)
how I can solve this problem?
You can do like this: Edit from your code
public Form1()
{
InitializeComponent();
cub xxx = new cub();
this.Controls.Add(xxx.createNewCub()); // Add the Label
}
class cub
{
public int cubWeight = 150;
public int cubHeight = 150;
public Label createNewCub() //change void to Label
{
Label cubLabel = new Label();
cubLabel.Size = new Size(cubWeight, cubHeight);
cubLabel.Text = "GeeksforGeeks";
cubLabel.Location = new Point(500, 200);
cubLabel.Font = new Font("Calibri", 18);
cubLabel.ForeColor = Color.Green;
cubLabel.Padding = new Padding(6);
return cubLabel; //return label
}
}

User control using panel and labels dynamically added horizontally

I am trying to create a user control using a Windows Forms Panel and number of Labels with some text dynamically added to the Panel horizontally. I am trying with below code and the Labels get overridden.
public partial class AllergyBar : Panel
{
public AllergyBar()
: base()
{
InitializeComponent();
}
int X = 0, Y=0;
int height, width;
public AllergyBar(List<String> lstAlerts)
: base()
{
this.BackColor = System.Drawing.Color.WhiteSmoke;
this.Name = "panel2";
this.Size = new System.Drawing.Size(75, 23);
this.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;
foreach (string alert in lstAlerts)
{
Label AllergyLabel = new Label();
AllergyLabel.Text = alert;
width = AllergyLabel.Size.Width;
Y = AllergyLabel.Location.Y;
AllergyLabel.Location = new System.Drawing.Point(X+width, Y);
AllergyLabel.Size = new System.Drawing.Size(75, 23);
AllergyLabel.AutoSize = true;
AllergyLabel.BorderStyle = BorderStyle.FixedSingle;
AllergyLabel.Dock = DockStyle.Fill;
this.Controls.Add(AllergyLabel);
}
InitializeComponent();
}
}
You have to update X value at the end of each loop:
public partial class AllergyBar : Panel
{
public AllergyBar(): base()
{
InitializeComponent();
}
int X = 0, Y=0;
int height, width;
public AllergyBar(List<String> lstAlerts): base()
{
InitializeComponent();
this.BackColor = System.Drawing.Color.WhiteSmoke;
this.Name = "panel2";
this.Size = new System.Drawing.Size(75, 23);
this.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;
foreach (string alert in lstAlerts)
{
Label AllergyLabel = new Label();
AllergyLabel.Text = alert;
AllergyLabel.Location = new System.Drawing.Point(X, Y);
AllergyLabel.AutoSize = true;
AllergyLabel.BorderStyle = BorderStyle.FixedSingle;
AllergyLabel.Dock = DockStyle.Fill;
X += AllergyLabel.Width;
this.Controls.Add(AllergyLabel);
}
}
}

ObjectDisposedException when moving form

I made a custom form.
Now I'm trying to implement the feature to drag the form around while holding the titlebar. But it always throws this exception:
