我尝试使用“绑定导航器添加”按钮添加新记录。我有三个字段可以在新记录中默认设置。用户ID,开始时间和结束时间。使用下面的代码,我可以设置开始时间和结束时间,但不能设置用户组合框。无法设置该值吗?
我尝试在BindingNavigatorAddNewItem_Click中设置值
Private Sub BindingNavigatorAddNewItem_Click(sender As Object, e As EventArgs) Handles BindingNavigatorAddNewItem.Click
'MsgBox("Add new Log")
Dim User As String = currUser.Name
Dim Index As Integer = cmbOperator.FindString(User)
cmbOperator.SelectedIndex = Index
cmbOperator.SelectedItem = User
dtpLogIn_Date.Value = currUser.Start_Time
dtpLogOut_Date.Value = currUser.End_Time
End Sub
答案 0 :(得分:0)
一种解决方案是在BindingSource_PositionChanged事件中设置cmbOperator索引。我的猜测是在记录位置更改后会触发这种情况。然后,将其包装在代码中,以检查是否为新增内容。可能也可以将它放在BindingNavigator_PositionChanged中。
Dim varShiftKey = Shift_LogBindingSource.Current("Shift_Key")
If varShiftKey = -1 Then
Dim User As String = currUser.Name
Dim Index As Integer = cmbOperator.FindString(User)
cmbOperator.SelectedIndex = Index
End If
