Create windows forms dynamically

Here's a simple example for creating key/value pair editors:

Form form = new Form();
form.Location = new Point(x, y);

form.Width = 200;
form.SuspendLayout();
int usedHeight = 0;

foreach(KeyValuePair<string,> kvp in someDictionary){
 Label label = new Label();
 label.Text = kvp.Key;
 label.Top = usedHeight + 7; label.Left = 5;
 form.Controls.Add(label);
 
 TextBox textBox = new TextBox();
 textBox.Text = kvp.Value;
 textBox.Top = usedHeight + 5; textBox.Left = 80;
 textBox.Width = 115;
 textBox.Anchor = AnchorStyles.Left | AnchorStyles.Top | AnchorStyles.Right;
 form.Controls.Add(textBox);

 usedHeight += textBox.Height + 5;
}

form.ResumeLayout();
form.Height = usedHeight + 10;

What you might want to do is dynamically fill a panel, and have other panels around the edges of your form with their Dock property set. That way you can use the designer to make an OK/Cancel button bar, menus, toolbar etc, and just have a panel in the middle with dynamic content (and set the size of the form appropriately). Dynamically creating entire forms is probably less useful.

I used something similar to this to bring up a selection dialog where the number of options to check wasn't known at design time (it was a list of data sets to operate on, which can be added by the user). In that case I had a GroupBox which was dynamically sized and several other controls in a panel docked to the top or the bottom made in the designer.
