什么是C＃winform中的等效UpdateSourceTrigger？

Question

我有问题。 C＃windows应用程序中的什么是等效的UpdateSourceTrigger？

public static void Bind(ComboBox cmb, ComboVAlidationRule vld) 
     { 
      Binding bndControl = new Binding("DataBind"); 
      bndControl.Source = vld; 
      bndControl.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged; 
      bndControl.ValidationRules.Add(vld); 
      cmb.SetBinding(ComboBox.SelectedItemProperty, bndControl); 
     }

Binding.DataSourceUpdateMode是你在找什么。

using System.Windows.Forms; 

// ... 

    Binding binding = new Binding("Text", this.personBindingSource, "Name"); 
    binding.DataSourceUpdateMode = DataSourceUpdateMode.OnPropertyChanged; 

    this.nameTextBox.DataBindings.Add(binding);
