WPF：数据与code绑定 [英] WPF: Data binding with code

问题描述

我如何使用数据绑定从code（C＃或VB）？

这是我到目前为止，但它显示 Binding.ToString 而不是 m_Rep.FirstName 。

 公共只读属性TabCaption作为对象
    得到
        返回新标签用{.Foreground = Brushes.Black，.Content =新绑定（名字），.DataContext = m_Rep}
    到底得的

解决方案

是的，在code结合是直的分配（这是XAML如何使它看起来像它的工作原理）有一点不同。

我可以给你在C＃中的例子 - 不应该太远VB.NET中删除

  VAR标签=新标签{前景= Brushes.Black，DataContext的= m_Rep};
label.SetBinding（Label.ContentProperty，新的绑定（名字））;
返回标签;
 

所以SetBinding的方法绑定（在DataContext的）中的名字路径标签的内容属性。

How do I use data-binding from code (C# or VB)?

This is what I have so far, but it is displaying Binding.ToString instead of m_Rep.FirstName.

Public ReadOnly Property TabCaption As Object 
    Get
        Return New Label With {.Foreground = Brushes.Black, .Content = New Binding("FirstName"), .DataContext = m_Rep}
    End Get
End Property

解决方案

Yes, binding in code is a little different from straight assignment (which is how XAML makes it look like it works).

I can give you an example in C# - shouldn't be too far removed from VB.NET.

var label = new Label { Foreground = Brushes.Black, DataContext = m_Rep };
label.SetBinding(Label.ContentProperty, new Binding("FirstName"));
return label;

So the "SetBinding" method binds the "FirstName" path (of the DataContext) to the label's Content property.
