问题
I am new to WinForms, and I am very used to styling in CSS, so maybe I am not looking at WinForm's Bottom Margin property correctly, but, no matter what element I set an arbitrarily large bottom-margin number to, it seems to have no effect, at all.
What I want is to extend the design of the form to below the initial viewable window (vertical-scroll bar shows up just fine), and set a bottom-margin to these elements so that the very bottom of the element isn't flush with the very bottom of the window (a little space would be nice).
I have tried this on several elements just to see if it was only the one element (or the fact that it was out of the initial visible part of the window) that was giving me problems, but I can't seem to get any effect out of the margin property at all.
Looking here: http://msdn.microsoft.com/en-us/library/ms229627.aspx It seems that this is, indeed, what the margin property should do. Also, I can't find any padding within the GUI controls for any element.
As it stands, I am mostly only coding C# for the event handlers, until I get a better grasp of where Visual Studio puts everything within the two partial classes (and the other .cs files).
If it helps, here is the code for the designer file:
namespace WindowsFormsApplication1
{
partial class IntroForm
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;
/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

/// the contents of this method with the code editor.

------------------------------------------UPDATE-------------------------------------------
The element I have set the bottom margin property to within the code above is simply, richTextBox1.
Also, I did find a Padding element to the main form element, but sadly, this doesn't push other elements away from its edges either :(
What do these properties do (margin, padding)?
回答1:
The Margin property is used by the automatic layout feature built into Winforms. But it does require that you allow the container to grow so it can provide the requested margin. So you must set the form's AutoSize property to True.
Combining AutoSize and AutoScroll is possible, you can set the MaximumSize property to prevent it from growing too much. The scrollbar automatically appears when the layout calculation produces a layout that exceeds the MaximumSize. The default maximum size is the Screen.WorkingArea on which the form is displayed, usually good enough.
