WPF 自定义控件的依赖属性的绑定方法

public partial class UC_ReagentWellTextBlock : UserControl
{
public UC_ReagentWellTextBlock()
{
//界面初始化
InitializeComponent();

//我这里需要绑定两个TextBlock,因此将这两个TextBlock进行绑定,绑定的是用于中转的变量,后续看的到.
Binding bindInformation = new Binding("InformationText") { Source = this };
this.TextBlockInformatioin.SetBinding(TextBlock.TextProperty, bindInformation);

Binding bindPosition = new Binding("PositionText") { Source = this };
this.TextBlockPosition.SetBinding(TextBlock.TextProperty, bindPosition);
}

//声明依赖属性.
public static readonly DependencyProperty PositionTextProperty = DependencyProperty.Register("PositionText", typeof(string), typeof(UC_ReagentWellTextBlock));
public static readonly DependencyProperty InformationTextProperty = DependencyProperty.Register("InformationText", typeof(string), typeof(UC_ReagentWellTextBlock));

//声明中转的变量
public string PositionText
{
get { return (string)GetValue(PositionTextProperty); }
set { SetValue(PositionTextProperty, value); }
}

public string InformationText
{
get { return (string)GetValue(InformationTextProperty); }
set { SetValue(InformationTextProperty, value); }
}
}
