public:
 void EndEdit();
public void EndEdit ();
member this.EndEdit : unit -> unit
Public Sub EndEdit ()

异常

该编辑操作破坏了约束。The edit broke a constraint.

此行属于该表,该编辑尝试更改只读列的值。The row belongs to the table and the edit tried to change the value of a read-only column.

该编辑操作尝试将 null 值放在 AllowDBNull 为 False 的列中。The edit tried to put a null value into a column where AllowDBNull is false.

示例

如果验证函数返回 true EndEdit , 则下面的示例使用方法DataRow来结束对值的编辑。The following example uses the EndEdit method to end the edit of a DataRow value if the validation function returns true.

   private void AcceptOrReject(DataRow row)
   {
       // Use a function to validate the row's values.
       // If the function returns true, end the edit;
       // otherwise cancel it.
       if(ValidateRow(row))
           row.EndEdit();
       else
           row.CancelEdit();
   }

   private bool ValidateRow(DataRow thisRow)
   {
       bool isValid = true; 
       // Insert code to validate the row values. 
       // Set the isValid variable.
       return isValid;
   }
 Private Sub AcceptOrReject(ByVal row As DataRow)
    ' Use a function to validate the row's values.
    ' If the function returns true, end the edit; 
    ' otherwise cancel it.
    If ValidateRow(row) Then
       row.EndEdit()
    Else
       row.CancelEdit()
    End If
End Sub
 
Private Function ValidateRow(ByVal row As DataRow) As Boolean
    Dim isValid As Boolean
    ' Insert code to validate the row values. 
    ' Set the isValid variable.
    ValidateRow = isValid
End Function

注解

设置属性时, 如果RowChanging事件中发生异常, 则会生成异常。When you set the property, an exception is generated if an exception occurs in the RowChanging event.
