When dynamically adding controls to a form only one will show

Question

I am adding two controls dynamically during runtime, however only the control that is made first is displayed.

Here is the code:

Label tempLab = new Label();
tempLab.text = "Test Label";
MyControl.Controls.Add(tempLab);
tempLab.Location = new Point(5,5);

Button tempBut = newButton()
tempBut.text = "Test Button";
MyControl.Controls.Add(tempBut);
tempBut.Location = new Point(20,20);

Isn't copypasta so ignore syntax errors with caps. Any ideas ?

They are being added to a groupbox. I have tried adding them to a panel or just the form and the same issue occurs. I don't need event handlers, so please don't cite that requirement.

Answer 1

I quickly tried your code pasting it in a windows form constructor. It runs ok, but the label is slightly overlapping the button because of its size. You may want to autosize it:

Label tempLab = new Label();
tempLab.Text = "Test Label";
tempLab.AutoSize = true;
Controls.Add(tempLab);
tempLab.Location = new Point(5,5);

Button tempBut = new Button();
tempBut.Text = "Test Button";
Controls.Add(tempBut);
tempBut.Location = new Point(20,20);

Oh, by the way. You mentioned you are using MyControl as a Panel or a GroupBox. Please ensure that you are also adding MyControl to your Controls collection.

Answer 2

it appears that the location does not have a Size which becomes a flat line so to speak which is not visible.. this tempBut.Location = new Point(20,20); try changing to this

this.tempBut.Location = new System.Drawing.Point(20,20); 
this.tempBut.Size = new System.Drawing.Size(30, 15);

hope this helps. I am adding a array of MyTextBox into panel.

         Point prevlocation = new Point(0,0);
         foreach (object key in keys)  //List of Objects or which make new controls
         {


            MyTextBoxControlArray[i] = new MyTextBoxUserControl(key);   //User control but could be any control like textbox etc
            MyTextBoxControlArray[i].Width = this.panel1.Width - 50;
            MyTextBoxControlArray[i].AutoSize = true;
            MyTextBoxControlArray[i].InfoLoad += new MyTextBoxUserControl.InfoLoadEventHandler(Form1_InfoLoad);

            if (i == 0)
            {
                //first control
                prevlocation.Y += 3;
                prevlocation.X += 3;
                MyTextBoxControlArray[i].Location = prevlocation;
            }
            else
            {
            //adjsuting height and width
                MyTextBoxControlArray[i].Location = new System.Drawing.Point(
                             prevlocation.X,
                             prevlocation.Y + MyTextBoxControlArray[i].Height+3);
            }

            prevlocation = MyTextBoxControlArray[i].Location;

            i++;
        }

        this.panel1.Controls.AddRange(MyTextBoxControlArray); //in panel i can add a array of controls , but this could be done one by one
