这是我的网格视图。

<asp:GridView ID="gridview1" runat="server" AutoGenerateColumns="False" CellPadding="4"
OnPageIndexChanging="gridview1_PageIndexChanging" ForeColor="#333333" GridLines="None"

                            </FooterTemplate>
                        </asp:TemplateField>
                        <asp:TemplateField HeaderText="Net Salary">
                            <ItemTemplate>
                                <asp:Label ID="lblns" runat="server"></asp:Label>
                            </ItemTemplate>
                            <FooterTemplate>
                                <asp:Label ID="lblnewns" runat="server"></asp:Label>
                            </FooterTemplate>
                        </asp:TemplateField>
                    </Columns>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

如您所见，在第一个网格视图（gridview1）中，它有另一个网格视图（gridview2）。这是我的表： enter image description here

净工资的价值=总薪资 - E.P.F.

如何计算净薪水的价值？

Answer 1

更改.ASPX文件中的以下内容。

<asp:TemplateField HeaderText="Net Salary">
                            <ItemTemplate>
                                <asp:Label ID="lblns" runat="server" Text='<%# GetNetSalary(Eval("GROSS_SALARY"),Eval("epf")) %>'></asp:Label>
                            </ItemTemplate>
                            <FooterTemplate>
                                <asp:Label ID="lblnewns" runat="server"></asp:Label>
                            </FooterTemplate>
                        </asp:TemplateField>

在.CS文件中添加此

private string GetNetSalary(object grossSalary,object epf)
{
return (grossSalary - epf).ToString();
}

感谢您抽出宝贵时间阅读我的问题。我已经有了解决方案。

<asp:TemplateField HeaderText="Net Salary">
                        <ItemTemplate>
                            <asp:Label ID="lblns" runat="server" Text='<%# Convert.ToDouble(Eval("GROSS_SALARY")) - ConvertToDouble(Eval("epf")) %>'></asp:Label>
                        </ItemTemplate>
                        <FooterTemplate>
                            <asp:Label ID="lblnewns" runat="server"></asp:Label>
                        </FooterTemplate>
                    </asp:TemplateField>
