这里:    rx.Text = "产品数目: " & Rows.Count,求的是产品数目,如果要求选定类别的产品的库存量,公式该怎么写

或者在最后加入一行,对当前列进行合计

rx.Text = "产品数目: " & Rows.Count

 

改为:

 

rx.Text = "产品数目: " & DataTables("产品").Compute("Sum(库存)", "关联列 = \'" & tbl.Rows(i)("关联列")  & "\'")

 

 

或者:

 

Dim sum As integer = 0

For Each sr as row in rows

     sum = sum + sr("库存")

next

rx.Text = "产品数目: "  & sum

如果有一逻辑列,只对选定的列的存求合计,上面的公式又该怎样定啊

打错了:是

Dim sum As integer = 0

For Each sr as row in rows

     if r("逻辑列") = True Then

          sum = sum + sr("库存")

    End if

next

rx.Text = "产品数目: "  & sum
