我想在GridView
:
NetAmount = (ServiceAmount * Quantity) * Discount
我在RowDataBound
编写了代码,但它无效。有人可以帮我解决这个问题吗?如果有人分享他们的知识,我将不胜感激。
我的Aspx代码:
<asp:GridView ID="GridView1" runat="server" Height="156px" Width="618px"
AutoGenerateColumns="False" BorderWidth="1px"
HorizontalAlign="Justify" onrowdatabound="GridView1_RowDataBound"
BackColor="LightGoldenrodYellow" BorderColor="Tan" CellPadding="2"
ForeColor="Black" GridLines="None" onrowcommand="GridView1_RowCommand">
<FooterStyle BackColor="Tan" />
<PagerStyle BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" />
<HeaderStyle BackColor="#FFFFC4" Font-Bold="True" ForeColor="#BF6000"/>
<Columns>
<!-- snip -->
<asp:TemplateField HeaderText="Net Amt">
<ItemTemplate>
<asp:TextBox ID="TxtNetAmt" ReadOnly="true" Font-Bold="true" ForeColor="#BF6000" runat="server" Width="55px"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<AlternatingRowStyle BackColor="PaleGoldenrod" />
</asp:GridView>
<script type="text/javascript">
function CalcSercode(ServiceAmount,Quantity, Discount,NetAmount)
{
var Quantity=parseFloat(document.getElementById(Quantity).value);
var Discount= parseFloat(document.getElementById(Discount).value);
var ServiceAmount=document.getElementById(ServiceAmount);
var SerAmountValue = parseFloat((ServiceAmount * Quantity)-((ServiceAmount *Quantity)*Discount/100));
//var SellPriceValueRound = Math.round(SellPriceValue,4);
var SerAmountValueRound = SerAmountValue;
ServiceAmount.innerHTML= SerAmountValueRound ;
}
</script>
我的cs代码:
//TextBox TxtServiceCode = GridView1.Controls[0].Controls[0].FindControl("TxtServiceCode") as TextBox;
//DataSet dss = new DataSet();
//SqlConnection MyConnection = new SqlConnection("server=prog; database=mydatabase;UID=sa;PWD=naco123;");
//SqlCommand sqlcmd = new SqlCommand("select * from [ServiceCode]", MyConnection);
//SqlDataAdapter adp = new SqlDataAdapter(sqlcmd);
//DataSet ds = new DataSet();
//adp.Fill(ds);
//GridView1.DataSource = ds.Tables[0];
//GridView1.DataBind();

您应该能够使用内联数据绑定语法进行计算:
<ItemTemplate>
<%# ((Convert.ToDecimal(Eval("ServiceAmount")) * Convert.ToInt32(Eval("Quantity"))) * Convert.ToDecimal(Eval("Discount"))).ToString("C") %>
</ItemTemplate>

一般情况下,我建议您不要在前端进行此计算,但要么在业务层中,要么在您的情况下,您似乎没有,直接进入数据库。
因此,不要将NetAmount =(ServiceAmount * Quantity)* Discount添加到您的select语句中。如果您这样做,您可以简单地将该列数据绑定到您的网格,因为它无论如何都是只读
