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:

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:

} base.Dispose(disposing); } #region Windows 窗体设计器生成的代码 /// <summary> /// 设计器支持所需的方法 - 不要 /// 使用代码编辑器修改此方法的内容。 /// </summary> private void InitializeComponent() { this.components = new System.ComponentModel.Container(); this.barManager1 = new DevExpress.XtraBars.BarManager(this.components); this.bar1 = new DevExpress.XtraBars.Bar(); this.bar2 = new DevExpress.XtraBars.Bar(); this.barButtonItemDemo = new DevExpress.XtraBars.BarButtonItem(); //手动添加下面代码 CodeTest this.CodeTest = new DevExpress.XtraBars.BarButtonItem(); this.bar3 = new DevExpress.XtraBars.Bar(); this.barDockControlTop = new DevExpress.XtraBars.BarDockControl(); this.barDockControlBottom = new DevExpress.XtraBars.BarDockControl();

this.SuspendLayout(); // // barManager1 // this.barManager1.Bars.AddRange(new DevExpress.XtraBars.Bar[] { this.bar1, this.bar2, this.bar3}); this.barManager1.DockControls.Add(this.barDockControlTop); this.barManager1.DockControls.Add(this.barDockControlBottom); this.barManager1.DockControls.Add(this.barDockControlLeft); this.barManager1.DockControls.Add(this.barDockControlRight); this.barManager1.Form = this; this.barManager1.Items.AddRange(new DevExpress.XtraBars.BarItem[] { this.barButtonItemDemo //手动添加下面代码 CodeTest , this.CodeTest}); this.barManager1.MainMenu = this.bar2; this.barManager1.MaxItemId = 3;

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。
