DataGridView.CellErrorTextChanged 事件

定义

在单元格的 ErrorText 属性值更改时发生。Occurs when the value of the ErrorText property of a cell changes.

public:
 event System::Windows::Forms::DataGridViewCellEventHandler ^ CellErrorTextChanged;
public event System.Windows.Forms.DataGridViewCellEventHandler CellErrorTextChanged;
member this.CellErrorTextChanged : System.Windows.Forms.DataGridViewCellEventHandler 
Public Custom Event CellErrorTextChanged As DataGridViewCellEventHandler 

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 @no__t 的事件发生。In the example, an event handler reports on the occurrence of the CellErrorTextChanged 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,请考虑将 @no__t 0 替换为 Console.WriteLine,或将消息附加到多行 TextBoxTo 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 @no__t DataGridView 类型实例的项目中。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 @no__t 0 事件关联。Then ensure that the event handler is associated with the CellErrorTextChanged event.

private void DataGridView1_CellErrorTextChanged(Object sender, DataGridViewCellEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ColumnIndex", e.ColumnIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "RowIndex", e.RowIndex );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "CellErrorTextChanged Event" );
}
Private Sub DataGridView1_CellErrorTextChanged(sender as Object, e as DataGridViewCellEventArgs) _ 
     Handles DataGridView1.CellErrorTextChanged

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

End Sub
