只是为了开始,我对C#和xaml很新.
我已经看过,检查了教程,关于绑定,但是我看到的大部分内容在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,我将在以后的代码中定义几个对象.一般我想绑定到文本框.
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));
}
}
最终我会有很多(数值)属性,它将显示在几个文本框中,因为该软件是作为发送测量数据的外部硬件组件的接口.我尝试了几种有约束力的方法,但我还没有成功.我将非常感谢一个例子如何将前面提到的属性绑定到一个TextBox.
解决方法
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();
}
}
XAML
<TextBox Text="{Binding Path=TestString}" />
将MainWindow绑定为数据标签的示例：
public partial class MainWindow : Window
{
MyTestObject myTestObject;
public MyTestObject MyTestObjectProperty { get { return myTestObject; } }
public MainWindow()
{
myTestObject = new MyTestObject ();
this.DataContext = this;
InitializeComponent();
}
}
XAML
<TextBox Text="{Binding Path=MyTestObjectProperty.TestString}" />
