Caliburn.Micro：一个按钮已经绑定按照约定的方法绑定文本 [英] Caliburn.Micro: Bind text of a button that is already bound by convention to a method

问题描述

我使用Caliburn.Micro出色的公约为基础的结合一键绑定到我的视图模型的方法。事情是，我希望按钮的内容绑定到一个字符串视图模型的属性。

目前，我允许约定的方式结合，并明确约束力的内容。这里有一个例子：

例如：

 ＆LT;按钮X：名称=提交CONTENT ={结合SubmitCaption}/＆GT;

公共类MyViewModel：PropertyChangedBase
{
    公共无效提交（）{}
    公共字符串SubmitCaption {获得;组; } //技术上将提高PropertyChanged事件
}
 

不过，我在想，如果有有这样做的更优雅的方式？我在考虑覆盖的按钮约定，以便它仍然绑定按钮操作的方法，但内容到指定的按约定财产。

 ＆LT;按钮X：名称=提交/＆GT;

公共类MyViewModel：PropertyChangedBase
{
    公共无效提交（）{}
    公共字符串SubmitContent {获得;组; } //技术上将提高PropertyChanged事件
}
 

解决方案

您可以自定义所有按键的默认行为，但我认为你目前的方法更明确，明显给开发商，而似乎没有特别讨厌的。我会建议与你有什么坚持。

如果你决定要在按钮的内容要多字符串会发生什么？你让 SubmitContent 的对象类型？你会设置它在code值？这听起来很厉害了我。

I'm using Caliburn.Micro's excellent convention-based binding to bind a button to a method on my view model. Thing is, I want the Content of the button to be bound to a string property of the view model.

At the moment I'm allowing the convention binding for the method, and an explicit binding for the content. Here's an example:

E.g.:

<Button x:Name="Submit" Content="{Binding SubmitCaption}" />

public class MyViewModel : PropertyChangedBase
{
    public void Submit() {}
    public string SubmitCaption { get; set; } // Technically would raise PropertyChanged event
}

However I was wondering if there's there a more elegant way of doing this? I'm thinking about overriding the convention for buttons so that it still binds the button action to a method but the content to a named-by-convention property.

<Button x:Name="Submit" />

public class MyViewModel : PropertyChangedBase
{
    public void Submit() {}
    public string SubmitContent { get; set; } // Technically would raise PropertyChanged event
}

解决方案

You could customise the default behaviour for all buttons, but I think your current approach is more explicit and obvious to developers, and doesn't seem particularly nasty. I would recommend sticking with what you've got.

What happens if you decide you want the Button content to be more than a string? Do you make SubmitContent an object type? Would you set its value in code? That sounds nastier to me.
