DataGridView.RowErrorTextChanged DataGridView.RowErrorTextChanged DataGridView.RowErrorTextChanged DataGridView.RowErrorTextChanged Event

定义

在行的 ErrorText 属性更改时发生。Occurs when the ErrorText property of a row changes.

public:
 event System::Windows::Forms::DataGridViewRowEventHandler ^ RowErrorTextChanged;
public event System.Windows.Forms.DataGridViewRowEventHandler RowErrorTextChanged;
member this.RowErrorTextChanged : System.Windows.Forms.DataGridViewRowEventHandler 
Public Custom Event RowErrorTextChanged As DataGridViewRowEventHandler 

示例

下面的代码示例演示如何使用此成员。The following code example demonstrates the use of this member. 在此示例中, 事件处理程序报告RowErrorTextChanged事件的发生。In the example, an event handler reports on the occurrence of the RowErrorTextChanged event. 此报表可帮助你了解何时发生事件, 并可帮助你进行调试。This report helps you to learn when the event occurs and can assist you in debugging. 若要报告多个事件或频繁发生的事件, 请考虑MessageBox.ShowConsole.WriteLine消息替换为多行或将TextBox其追加到多行。To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

若要运行示例代码, 请将其粘贴到包含名为DataGridView DataGridView1的类型的实例的项目中。To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. 然后, 确保事件处理程序与RowErrorTextChanged事件相关联。Then ensure that the event handler is associated with the RowErrorTextChanged event.

private void DataGridView1_RowErrorTextChanged(Object sender, DataGridViewRowEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Row", e.Row );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RowErrorTextChanged Event" );
}
Private Sub DataGridView1_RowErrorTextChanged(sender as Object, e as DataGridViewRowEventArgs) _ 
     Handles DataGridView1.RowErrorTextChanged

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

End Sub
