Dynamically create array of textboxes and labels winforms

Question

I need to create an array of label and text boxes dynamically.

I have a groupBox and I need to add the above to it. What is the best way to align then correctly? How do you get the location?

below does not work

    public void TestCreateInputLabelAndTextBox()
    {

        foreach (Parameter parameter in Params)
        {
            var lbl = new Label();
            lbl.Name = "lbl" + parameter.Name;
            lbl.Text = parameter.Name;
            lbl.AutoSize = true;
            lbl.Location = new Point(7, 30);
            lbl.Name = "label1";
            lbl.Size = new Size(35, 13);


            var txtBox = new TextBox();
            txtBox.Name = "txt" + parameter.Name;
            txtBox.Text = parameter.Name;
            txtBox.Location = new Point(20, 20);
            txtBox.Location = new Point(49, 22);
            txtBox.Size = new Size(100, 20);


            groupBox1.Controls.Add(lbl);
            groupBox1.Controls.Add(txtBox);
        }

    }

How do you do it?

How would you calculate their locations with pen-and-paper? Try that first, then take your logic and convert it to code. — mellamokb

Consider ditching the labels and textboxes and use a datagridview instead. Then all you need to do is add rows. — LarsTech

Use standard containers like FlowLayoutPanel, TableLayoutPanel, etc for aligning purpose. — Angshuman Agarwal

If they're all going to be the same size, you can have them located at fixed intervals. You'll need a starting location and then add to that for each new textbox and label. — Jon Senchyna

The reason you're getting random suggestions is that we don't understand what problem you're trying to solve. Why do you need to do this? What "does not work" about what you are doing? — Dour High Arch

you must make an array of textbox and lable for example:

TextBox[] txt= new TextBox[10];
for (int i = 0; i <=10; i++) {
    txt(i) = new TextBox();
    txt(i).Text = i.Tostring();
    if (i > 0) {
        txt(i).Left = txt(i - 1).Right;
    }

    this.Controls.Add(txt(i));
}

Further to comments placed above I have used a tablePanelLayout.

I am sorry that my question seems not to have been clear. I tried to be as concise as possible because I beleive that the more you say the more you can confuse somebody who might help you.

All I needed was some pointers.By using a tablePanellayout solved my problem. thanks for your comments
