刚开始我对C#和xaml很新。
我已经看过,检查了教程,关于绑定,但我看到的大部分内容都在xaml中创建了一个对象。但是,我想在代码中创建对象,然后绑定到它的属性。此外,我将在稍后的代码中定义几个对象。一般来说,我想绑定到文本框。
一般来说,我的代码看起来像这样:
MainWindow.xaml.cs
public partial class MainWindow : Window
{
MyTestObject myTestObject;
public MainWindow()
{
myTestObject= new MyTestObject ();
this.DataContext = this;
InitializeComponent();
}
}
MyTestObject .cs
class MyTestObject : INotifyPropertyChanged
{
public MyTestObject ()
{
}
private string testString = "Test";
public string TestString
{
get { return testString; }
set
{
if (value == testString) return;
testString = value;
this.OnPropertyChanged("TestString");
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
this.PropertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
}
}
最终我将拥有相当多的(数字)属性,这些属性将显示在多个文本框中,因为该软件旨在作为发送测量数据的外部硬件组件的接口。我尝试了几种绑定方式,但我还没有成功。我非常感谢如何将前面提到的属性绑定到TextBox
。

将Datacontext设置为myTestObject。或者,为myTestObject创建一个公共属性,并将您的Xaml绑定设置为{Binding MyTestObjectPropertyHere.TestString}
例如:
public partial class MainWindow : Window
{
MyTestObject myTestObject;
public MainWindow()
{
myTestObject = new MyTestObject ();
this.DataContext = myTestObject;
InitializeComponent();
}
}
<强>的Xaml 强>
<TextBox Text="{Binding Path=TestString}" />
作为datacontext绑定到MainWindow的示例:
public partial class MainWindow : Window
{
MyTestObject myTestObject;
public MyTestObject MyTestObjectProperty { get { return myTestObject; } }
public MainWindow()
{
myTestObject = new MyTestObject ();
this.DataContext = this;
InitializeComponent();
}
}
<强>的Xaml 强>
<TextBox Text="{Binding Path=MyTestObjectProperty.TestString}" />
