主题：数据操作日志记录删除行

Dim cmd As New SQLCommand
cmd.CommandText = "SELECT * Fr om {数据操作日志} Where [_Identify] Is Null"
Dim dt As DataTable = cmd.ExecuteReader(True)
Dim dr As DataRow = dt.AddNew
dr("ID") = e.DataRow("_Identify")
dr("用户") = _UserName
dr("涉及表") = e.DataTable.Name
dr("涉及行") = e.DataRow("_Identify")
dr("修改时间") = Date.Now
dr("操作") = "删除了一行"
Dim str As String = ""
For Each c As DataCol In e.DataTable.DataCols
    str += c.Name & "=" & e.DataRow(c.Name) & "|"
Next
dr("原行数据") = str

AfterOpenProject 代码

For Each dt As DataTable In DataTables
    dt.GlobalHandler.DataColChanged = True
    dt.GlobalHandler.DataRowAdded = True
    dt.GlobalHandler.DataRowDeleted = True
Next

请老师指点错在哪？谢谢

没有报错提示，数据操作日志没有删除记录

已经保存了

找到问题了

For Each dt As DataTable In DataTables
    dt.GlobalHandler.DataColChanged = True
    dt.GlobalHandler.DataRowAdded = True
    dt.GlobalHandler.DataRowDeleting = True
Next
