How to add radio buttons dynamically in Windows form?

I need to add radio buttons dynamically in my windows form and in horizontal mode. Sample

for (int i = 0; i <= r.Count; i++)
{
RadioButton rdo = new RadioButton();
rdo.Name = "id";
rdo.Text = "Name";
rdo.ForeColor = Color.Red;
rdo.Location = new Point(5, 30 );
this.Controls.Add(rdo);
}

You can do something like this

//This is my dynamic data list
List<ItemType> itemTypeData = new List<ItemType>()

RadioButton[] itemTypes = new RadioButton[ItemType.Count];
int locationX = 0;
for (int i = 0; i < ItemType.Count; i++)
{
     var type = ItemType[i];
     itemTypes[i] = new RadioButton
     {
         Name = type.Code,
         Text = type.Code,
         AutoSize = true,
         Font = new System.Drawing.Font("Calibri", 11F, FontStyle.Regular),
         Location = new Point(156 + locationX, 88),
     };
                
     this.Controls.Add(itemTypes[i]);
     locationX += 80;
}

This works fine for me

You could do something like this:

FlowLayoutPanel pnl = new FlowLayoutPanel();
pnl.Dock = DockStyle.Fill;

for (int i = 0; i < 4; i++)
{
    pnl.Controls.Add(new RadioButton() { Text = "RadioButton" + i });
}

this.Controls.Add(pnl);

You could also add the FlowLayoutPanel in the designer and leave that part out in the code.

To get the selected RadioButton use a construct like this:

RadioButton rbSelected = pnl.Controls
                         .OfType<RadioButton>()
                         .FirstOrDefault(r => r.Checked);

To use this the FlowLayoutPanel needs to be known in the calling method. So either add it to the Form in the designer (Thats what I would prefer) or create it as an instance member of the form and add it at runtime (this has no benefit).
