更新时截断列总计的数据

Question

我在 C# 中使用 Telerik，我有 2 个 gridcalculatedcolumn 和 2 个 gridtemplatecolumn，带有页脚和 1 个按钮。在我的表格中，列类型是双倍的。我得到的值是正确的。当我按下按钮时，我试图更新我的数据库上的值，并且我在添加参数的行中截断了列总计的数据。

为什么我会收到此消息以及如何解决此问题？

输入 aspx：

 <telerik:GridTemplateColumn Aggregate="Sum"  FooterText="Total Discount: " DataField="DiscAmount" DataType="System.Decimal" FilterControlAltText="Filter DiscAmount column" HeaderText="DiscAmount(€)" SortExpression="DiscAmount" UniqueName="DiscAmount">
                    <EditItemTemplate>
                        <asp:TextBox ID="DiscAmountTextBox" runat="server" Text='<%# Bind("DiscAmount") %>' AutoPostBack="true"  OnTextChanged="DiscAmount_TextChanged" ></asp:TextBox>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:Label ID="DiscAmountLabel" runat="server" Text='<%# Eval("DiscAmount") %>'></asp:Label>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>
   <telerik:GridTemplateColumn Aggregate="Sum"  FooterText="Total NetAmount: "    DataField="NetAmount" DataType="System.Decimal" FilterControlAltText="Filter  NetAmount column" HeaderText="NetAmount(€)" SortExpression="NetAmount" UniqueName="NetAmount">
                    <EditItemTemplate>
                     <asp:TextBox ID="NetAmountTextBox" runat="server" Text='<%# Bind("NetAmount") %>' Enabled="false" ></asp:TextBox>
                 </EditItemTemplate>
                    <ItemTemplate>
                        <asp:Label ID="NetAmountLabel" runat="server" Text='<%# Eval("NetAmount") %>'></asp:Label>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>

          <telerik:GridCalculatedColumn HeaderText="Total VAT" UniqueName="TotalVAT" DataType="System.Decimal" DataFormatString="{0:F}"
                    DataFields="price,VAT" FooterText="Total Vat : "  Expression="({0}*({1}/100))" 
                    Aggregate="Sum" />
          <telerik:GridCalculatedColumn HeaderText="Total Price" UniqueName="TotalPrice" DataType="System.Decimal" DataFormatString="{0:F}"
                    DataFields="price,DiscAmount,VAT" Expression="(({0}-{1})*({2}/100))+({0}-{1})" FooterText="Total : "
                    Aggregate="Sum" />

aspx.cs:

  GridFooterItem footeritem = (GridFooterItem)RadGrid1.MasterTableView.GetItems(GridItemType.Footer)[0];
                double footervat = Convert.ToDouble( footeritem["TotalVAT"].Text);
                string footerprice =  footeritem["TotalPrice"].Text;
                string footerdisc = footeritem["DiscAmount"].Text;
                string footernetamount = footeritem["NetAmount"].Text;

            string[] words = footernetamount.Split(' ');
            footernetamount = words[2];
            string[] words2 = footerdisc.Split(' ');
            footerdisc = words[2];
            string insdocheader = "UPDATE mytable SET Total=@netAmount, AmountDue=@footerprice,VAT=@footervat,Discount=@footerdisc WHERE DocNo=@docnoparam and DocStatus=@docstatusparam";


               MySqlCommand cmd3 = new MySqlCommand(insdocheader, con2);
               cmd3.Parameters.AddWithValue("docnoparam", DocNoTxtBox.Text);
               cmd3.Parameters.AddWithValue("docstatusparam", 2);
              con2.Open();

            cmd3.Parameters.AddWithValue("netAmount", footernetamount);
            cmd3.Parameters.AddWithValue("footerprice", footerprice);
            cmd3.Parameters.AddWithValue("footervat", footervat);
            cmd3.Parameters.AddWithValue("footerdisc", footerdisc);
                cmd3.ExecuteNonQuery();

更新 我已经更改了此代码并且正在工作！我将 ',' 替换为 '.'

 string[] words = footernetamount.Split(' ');
            footernetamount = words[2];
            string[] words3 = footernetamount.Split(',');
            footernetamount = words3[0] + "." + words3[1];

有没有更简单的方法或者我必须这样做？

Answer 1

我已将 ',' 替换为 '.'并且正在工作

string[] words = footernetamount.Split(' ');
            footernetamount = words[2];
            string[] words3 = footernetamount.Split(',');
            footernetamount = words3[0] + "." + words3[1];
