有没有谁知道这个？

我一直在尝试这种在过去的一周，没有运气。

现在我可以看到，一旦可以成功地绑定到一个按钮的Text属性，而不是它的ImageKey属性：

  myButton.Text =新文本; //真正改变绑定的数据
myButton.ImageKey =新文本; //不改变绑定的数据
 

我使用的：

  myButton.DataBindings.Add（新绑定（ImageKey，this.MyData，姓名，真实，DataSourceUpdateMode.OnPropertyChanged））;
 

为什么呢？是什么让绑定滴答/工作？我只是不明白这一点。

编辑：

行，所以我定义了这些我自己的派生控件：

 公共事件的EventHandler ImageKeyChanged;

受保护的虚拟无效OnImageKeyChanged（EventArgs的发送）
{
    如果（ImageKeyChanged！= NULL）
    {
    ImageKeyChanged（这一点，E）;
    }
}

[可绑定（真）
大众新的字符串ImageKey
{
    得到
    {
    返回base.ImageKey;
    }
    组
    {
    base.ImageKey =价值;
    this.OnImageKeyChanged（EventArgs.Empty）;
    }
}
 

它仍然无法正常工作。有上了网，这显示了该教程什么的。它只是不适合我。

...不会更改绑定的数据

2双向绑定，你需要通知的事件 - 这可能需要2常见的形式：

这肯定是如何对象到控制结合的作品;我是pretty的确保控制到对象的检测是非常相似的。请注意，有一个框TextChanged 事件，但没有 ImageKeyChanged 事件。

Is there anyone who knows this?

I have been trying this for the last week, and no luck.

Now I can see that once can bind successfully to a Button's Text property, but not its ImageKey property:

myButton.Text = "new text"; // really changes the bound data
myButton.ImageKey = "new text"; // does NOT change the bound data

I use:

myButton.DataBindings.Add ( new Binding ( "ImageKey", this.MyData, "Name", true, DataSourceUpdateMode.OnPropertyChanged ) );

Why? What makes the Binding tick/work? I just don't get it.

EDIT:

OK so I defined these for my own derived control:

public event EventHandler ImageKeyChanged;

protected virtual void OnImageKeyChanged ( EventArgs e )
{
    if ( ImageKeyChanged!= null )
    {
    	ImageKeyChanged ( this, e );
    }
}

[Bindable ( true )]
public new string ImageKey
{
    get
    {
    	return base.ImageKey;
    }
    set
    {
    	base.ImageKey = value;
    	this.OnImageKeyChanged ( EventArgs.Empty );
    }
}

It still doesn't work. Is there a tutorial or something on the net, that shows this. It just doesn't work for me.

...does NOT change the bound data

for 2-way binding, you need notification events - this can take 2 common forms:

This is certainly how object-to-control binding works; I'm pretty sure that control-to-object detection is very similar. Note that there is a TextChanged event, but no ImageKeyChanged event.
