文本块绑定文本

[英]Textblock binding text

I want to display the string _lunedi in a textbox, the string _lunedi is updated periodically using InitializeBoxes().我想在文本框中显示字符串 _lunedi,使用 InitializeBoxes() 定期更新字符串 _lunedi。

I have my class:我有我的课:

public event PropertyChangedEventHandler PropertyChanged;
private string _lunedi= "lunedi ";
    public string lunedi
    {
        get { return this._lunedi; }

        set
        {
            if (value != this._lunedi)
            {
                this._lunedi = value;
                NotifyPropertyChanged("lunedi");
            }
        }
    }


    public void NotifyPropertyChanged(string propertyName)
    {
        if (this.PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }

whit this method change the lunedi:这个方法改变了lunedi:

private void InitializeBoxes()
    {
        lunedi += todayPivot.Day;
    }

xaml: xml:

<Border>
    <TextBlock Text="{Binding Path=lunedi, UpdateSourceTrigger=PropertyChanged}"></TextBlock>
</Border>

The problem is that the text of the textblock is empty.问题是文本块的文本是空的。 Thank you.谢谢你。

Sounds like the binding is using one time try this instead听起来绑定正在使用一次试试这个

<Border>
<TextBlock Text="{Binding Path=lunedi, Mode=OneWay}"></TextBlock>
