Hi!

I have a form inside a panel using:

public void CreateNewFormInsidePanel(){
Form form1 = new Form();
form1.TopLevel = false;
panel.Controls.Add(form1);
form1.Show();
form1.BringToFront();
}

Everything goes according plan when I'm creating a new form after a
button click event but when I want to create a new form inside a panel
just after initializing the main form it does not work.

public Main2()
{
InitializeComponent();
CreateNewFormInsidePanel();

}

The form appears inside the panel but without any label, combobox etc
initialized.

If I do a form1.show after the initialization the content of the form1
appears but of course not inside the panel.

Any help?
 
Hi Tiago M,

Although I don't quite understand why you would want to do this it should
work ok. I have used the following code to create a form within a panel (the
form contains a number of child controls that render correctly).

namespace FormInForm
{
public partial class FormMain : Form
{
public FormMain()
{
InitializeComponent();

FormEmbedded childForm = new FormEmbedded(); //Key line
childForm.TopLevel = false;
this.panelFormHolder.Controls.Add(childForm);
childForm.Show();
}
}
}

The one thing I did notice about your sample code was that you were creating
a form derived from the base class 'Form' and not from the actual form that
you want to display.

If the code line marked //Key line above is replaced with

Form childForm = new Form();

then child controls will not be rendered because the 'Form' base class does
not know about them.

Hope this helps.
