最近使用BarManager时候，发现一个问题就是在一开始把BarManager控件拖到窗体上的时候，控件上会有Add按钮，如下图：
此时，新增按钮或者其余类型的控件，方便无比。但有时候，当你新增完各个BarItem（Bar上的各个小控件，比如：BarButtonItem、BarCheckItem等等）后，再过一段时间，突然又有需求，要新增BarItem，发现Add按钮木有了，那应该怎么办呢？
解决方案：
通过代码添加。
代码修改前：
namespace IconTest
{
partial class Form1
{
///
/// 必需的设计器变量。
///
private System.ComponentModel.IContainer components = null;
///
/// 清理所有正在使用的资源。
///
/// 如果应释放托管资源，为 true；否则为 false。
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

/// 使用代码编辑器修改此方法的内容。

#endregion
private DevExpress.XtraBars.BarManager barManager1;

小注：虽然此时Bar上有Add按钮，但我们仍然通过代码添加BarItem。
比如我们仍然要添加一个按钮BarButtonItem，代码如下：
namespace IconTest
{
partial class Form1
{
///

///
private System.ComponentModel.IContainer components = null;
///
/// 清理所有正在使用的资源。
///
/// 如果应释放托管资源，为 true；否则为 false。
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

}
此时，就可以进行修改图片，点击事件之类的处理了，与通过Add按钮生成的用法一致。
小结：所谓的通过代码添加BarItem，即是参照之前的代码，手动复制修改一下即可。
