c - celltemp结合数据

Question

 <GridView AllowsColumnReorder="False">
      <GridViewColumn Header="Tên Mặt Hàng" CellTemplate="{StaticResource Ten}">
          <GridViewColumn.CellTemple>
                <DataTemplate x:Key="Ten">
                     <TextBlock Text="{Binding Ten}"></TextBlock>
                </DataTemplate>
          </GridViewColumn.CellTemple>
      </GridViewColumn> </GridView>

各位，我有代码，我想绑定(bind)textBlock的Text，以便在其他文件中再次使用数据，那我该怎么办？

Answer 1

您可以创建此 View 的 ViewModel。并将 viewModel 属性绑定(bind)到该 View 。例如:

public class NamViewModel: INotifyPropertyChanged {
    private string _ten;
    public string Ten {
        get
        {
           return _ten;
        }
        set 
        {
           _ten = value;
           this.RaisePropertyChanged("Ten");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    private void RaisePropertyChanged(string propertyName) {
        if (PropertyChanged != null) {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

然后你可以在 View 的构造函数中绑定(bind)这个viewModel。例如:

public partial class NamView : Window {
    public NamView() {
        InitializeComponent();
        this.DataContext = new NamViewModel();
    }
}
