DevExpress 在LayoutControl中放置控件保持布局居中显示

主体方法：嵌入两个LayoutControl。

效果如图：



窗体代码如下，关键代码加粗红色显示。

namespace WindowsFormsApplication1
{
partial class XtraForm11
{
/// <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);
}

#region Windows Form Designer generated code
