老师好
如果需要同步加载有两个关联列的子表，LoadChildren不支持，如何实现。谢谢！
换其它方式，比如：
http://www.foxtable.com/webhelp/topics/2228.htm
If DataTables("订单").DataRows.Count = 0 Then '如果订单表没有数据
DataTables("订单明细").LoadFilter = "关联列1 Is Null" '不加载订单明细
Else
Dim ids As String
For Each dr As DataRow In DataTables("订单").DataRows
ids = ids & ",'" & dr("关联列1") & dr("关联列2") & "'"
Next
ids= ids.Trim(",")
DataTables("订单明细").LoadFilter = "关联列1+关联列2 In (" & ids & ")"
End If
DataTables("订单明细").Load()
