Question

我正在尝试计算gridview行值并希望在文本框中显示。我在gridview，itemid，itemname，orderedqty，price，totalprice中有5行。当我点击这里添加行时，我想计算总价格总额。想把它显示给文本框。

我在尝试这是代码，我认为它不起作用。请帮我找到解决方案。

Public Sub Calculate()
    Dim Countrow As Integer = 1
    Dim AmountTotal As Decimal = 0

    For Each row As DataGridView In dgvPurchaseOrder.Rows
        Countrow += 1
        AmountTotal = dgvPurchaseOrder.Rows.Count.ToString()
    Next
    'GridView1.FooterRow.Cells(1).Text = "Total = " & AmountTotal.ToString()
    txtGrossTotal.Text = AmountTotal.ToString()
End Sub

Answer 1

尝试这样

   Public Sub Calculate()
        Dim Countrow As Integer = 1
        Dim AmountTotal As Decimal = 0

        For Each row As DataGridView In dgvPurchaseOrder.Rows
            Countrow += 1
            AmountTotal += row.Cells(4).Value  // give correct price column index
        Next
               txtGrossTotal.Text = AmountTotal.ToString()
    End Sub

Public Sub Calculate()
