问题描述
我是Lightswitch 2011的新手.
我要做的就是运行一个查询,如果返回结果则显示文本消息,如果为false则显示另一条文本消息.我可以这样做,但是当查询不变时,该消息不会出现.
我知道这是因为我使用了下面的Procedure SelectionChanged.我还能用什么呢?
I am new to Lightswitch 2011.
All I want to do is run a query that will show text message if results are returned and another text message if false.. I can do this , but when the query does not change, the message does not appear.
I know it is because I used the Procedure SelectionChanged below. What else could I possibly used.
Private Sub Query1_SelectionChanged()
Dim TotalCount As Integer
TotalCount = Me.Query1.Count
If TotalCount = 1 Then
Me.ShowMessageBox("This is a Bostik Part. Please check batch card again")
End If
If TotalCount = 0 Then
Me.ShowMessageBox("Please Press Enter to continue")
End If
End Sub
