定义

DataError 事件提供数据。Provides data for the DataError event.

public ref class BindingManagerDataErrorEventArgs : EventArgs
public class BindingManagerDataErrorEventArgs : EventArgs
type BindingManagerDataErrorEventArgs = class
    inherit EventArgs
Public Class BindingManagerDataErrorEventArgs
Inherits EventArgs

示例

下面的代码示例演示如何使用此类型。The following code example demonstrates the use of this type. 在示例中,事件处理程序报告的匹配项DataError事件。In the example, an event handler reports on the occurrence of the DataError event. 此报告可帮助您了解事件发生的并可以帮助您进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告或频繁发生的事件上多个事件,请考虑更换ShowConsole.WriteLine或将消息附加到多行TextBoxTo report on multiple events or on events that occur frequently, consider replacing Show with Console.WriteLine or appending the message to a multiline TextBox.

若要运行此代码示例,请将其粘贴到包含继承的类型的实例的项目BindingManagerBase,如PropertyManagerCurrencyManagerTo run the example code, paste it into a project that contains an instance of a type that inherits from BindingManagerBase, such as a PropertyManager or CurrencyManager. 然后该实例命名BindingManagerBase1,并确保事件处理程序相关联DataError事件。Then name the instance BindingManagerBase1 and ensure that the event handler is associated with the DataError event.

private void BindingManagerBase1_DataError(Object sender, BindingManagerDataErrorEventArgs e) {
    System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
    messageBoxCS.AppendFormat("{0} = {1}", "Exception", e.Exception);
    messageBoxCS.AppendLine();
    MessageBox.Show(messageBoxCS.ToString(), "DataError Event");
}
Private Sub BindingManagerBase1_DataError(sender as Object, e as BindingManagerDataErrorEventArgs) _ 
     Handles BindingManagerBase1.DataError

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Exception", e.Exception)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"DataError Event")

End Sub
