ComboBox的初始值为“AA”,下拉值为“AA|BB|CC”,如果选择了BB后,直接删除BB,此时ComboBox的值为空,如何返回到BB这值上去??
Dim tb02 As Table = Tables(e.Form.Name & "_Table02")
If e.Sender.Value = "往来付款明细" Then
tb02.DataSource = DataTables("往来付款明细")
tb02.SetColVisibleWidth(Tables("往来付款明细").GetColVisibleWidth())
ElseIf e.Sender.Value = "往来收款明细" Then
tb02.DataSource = DataTables("往来收款明细")
tb02.SetColVisibleWidth(Tables("往来收款明细").GetColVisibleWidth())
Else
MessageBox.Show("查询表类型不能为空!")
e.Sender.Value = ????
End If
