        {
            结合bndControl =新的绑定（的DataBind）;
            bndControl.Source = VLD;
            bndControl.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;

        }

<一个href=\"http://msdn.microsoft.com/en-us/library/system.windows.forms.binding.datasourceupdatemode.aspx\"相对=nofollow> Binding.DataSourceUpdateMode 是你要找的东西。

 使用System.Windows.Forms的;// ...    约束力181 =新的绑定（文本，this.personBindingSource，姓名）;
    binding.DataSourceUpdateMode = DataSourceUpdateMode.OnPropertyChanged;    this.nameTextBox.DataBindings.Add（绑定）;
 

I have question. what is equivalent UpdateSourceTrigger in C# windows application?

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);
        }

解决方案

Binding.DataSourceUpdateMode is what you're looking for.

using System.Windows.Forms;

// ...

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

    this.nameTextBox.DataBindings.Add(binding);
