如何以编程方式在C＃中连接ToolStripButton事件？

I'm programmatically adding ToolStripButton items to a context menu.

我是以编程方式将ToolStripButton项添加到上下文菜单中。

That part is easy.

那部分很容易。

this.tsmiDelete.DropDownItems.Add("The text on the item.");

However, I also need to wire up the events so that when the user clicks the item something actually happens!

但是,我还需要连接事件,以便当用户点击该项时实际发生的事情!

How do I do this? The method that handles the click also needs to receive some sort of id or object that relates to the particular ToolStripButton that the user clicked.

我该怎么做呢?处理点击的方法还需要接收某种与用户点击的特定ToolStripButton相关的id或对象。

Couldn't you just subscribe to the Click event? Something like this:

难道你不能订阅Click事件吗?像这样的东西:

ToolStripButton btn = new ToolStripButton("The text on the item.");
this.tsmiDelete.DropDownItems.Add(btn);
btn.Click += new EventHandler(OnBtnClicked);

And OnBtnClicked would be declared like this:

并且OnBtnClicked将被声明为:

private void OnBtnClicked(object sender, EventArgs e)
{
    ToolStripButton btn = sender as ToolStripButton;

    // handle the button click
}

The sender should be the ToolStripButton, so you can cast it and do whatever you need to do with it.

发件人应该是ToolStripButton,因此您可以投射它并做任何您需要做的事情。

Thanks for your help with that Andy. My only problem now is that the AutoSize is not working on the ToolStripButtons that I'm adding! They're all too narrow.

谢谢你对安迪的帮助。我现在唯一的问题是AutoSize不能处理我正在添加的ToolStripButtons!他们太狭隘了。

It's rather odd because it was working earlier.

这很奇怪,因为它提前工作了。

Update: There's definitely something wrong with AutoSize for programmatically created ToolStripButtons. However, I found a solution:

更新:对于以编程方式创建的ToolStripButtons,AutoSize肯定存在问题。但是,我找到了一个解决方案:

Create the ToolStripButton.

创建ToolStripButton。

Create a label control and set the font properties to match your button.

创建标签控件并设置字体属性以匹配您的按钮。

Set the text of the label to match your button.

设置标签的文本以匹配您的按钮。

Set the label to AutoSize.

将标签设置为AutoSize。

Read the width of the label and use that to set the width of the ToolStripButton.

读取标签的宽度并使用它来设置ToolStripButton的宽度。

It's hacky, but it works.

这很hacky,但它确实有效。
