-- 作者:zylzdsb -- 发布时间:2020/6/29 11:34:00 -- 记录窗口问题 请教请教,我要实现表中点击已结算后,给用户一个提示框,用户选择“是” 按钮后,锁定记录并勾选已结算,如下图1,然后选择“否”以后,就取消锁定与勾选,如下图2,表中能实现这功能,但记录窗口始终不能同步显示,需要点击另一条记录后,再回过去点刚刚修改的那个记录才能看到表与记录窗口都没有勾选,请问这是怎么一回事,如何才能实现这一功能呢?(图2中是点击“否”以后,表中的勾选没有了,但上面的记录窗口的勾选还存在,这样子会给用户一个错觉) 代码写在datacolchanged 事件里面 If Forms("明细录入").Opened() Then Dim lab7 As WinForm.Label = e.Form.Controls("Label7") Dim st As String = "" .PadLeft(1) If user.IsRole("结算") = False Then If e.DataRow("已结算") = True Then e.DataRow("已结算") = False MessageBox.Show("你无结算权限","提示",MessageBoxButtons.OK,MessageBoxIcon.Information) e.Cancel = True End If Else Dim chek As WinForm.CheckBox = Forms("明细录入").Controls("CheckBox1") If chek.Checked = False \'用于批量结算时跳过重复执行下面的消息提示 Dim Result As DialogResult If e.DataRow("已结算")=True Then Result = MessageBox.Show("请确认是否已结算,确认后将锁定此记录不能再修改?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question) If Result = DialogResult.Yes Then e.DataRow.Locked = True e.DataRow("已结算") = True e.DataTable.Save Else e.Cancel = True e.DataRow.Locked = False e.DataRow("已结算") = False \'主要是这一段代码,能改变表中状态,但不能改变记录窗口的状态 End If End If Dim drs As List(Of DataRow) drs = DataTables("支出总表").Select("[已结算] = \'false\' ") If drs.Count -1 >= 0 Then chek.Enabled =True chek.Checked = False End If End If Dim drss As List(Of DataRow) drss = DataTables("支出总表").Select("") If drss.Count -1 < 0 Then lab7.Text = "共有" & st & DataTables("支出总表").DataRows.Count & st & "条记录" Else If DataTables("支出总表").Compute("sum(未结算金额)") = Nothing Then lab7.Text = "共有" & st & DataTables("支出总表").DataRows.Count & st & "条记录" & st & st & "合计金额 :" & st & DataTables("支出总表").Compute("sum(金额)") & "元" & st & ",其中已结算:" & st & DataTables("支出总表").Compute("sum(已结算金额)") & "元" & st & ",未结算:" & st & "0" & st & "元" Else If DataTables("支出总表").Compute("sum(已结算金额)") = Nothing Then lab7.Text = "共有" & st & DataTables("支出总表").DataRows.Count & st & "条记录" & st & st & "合计金额 :" & st & DataTables("支出总表").Compute("sum(金额)") & "元" & st & ",其中已结算:" & st & "0" & "元" & st & ",未结算:" & st & DataTables("支出总表").Compute("sum(未结算金额)") & "元" Else lab7.Text = "共有" & st & DataTables("支出总表").DataRows.Count & st & "条记录" & st & st & "合计金额 :" & st & DataTables("支出总表").Compute("sum(金额)") & "元" & st & ",其中已结算:" & st & DataTables("支出总表").Compute("sum(已结算金额)") & "元" & st & ",未结算:" & st & DataTables("支出总表").Compute("sum(未结算金额)") & "元" End If End If End If End If End If |
