Asp.net CommanArgument传递未经处理的数字超出系统。FormatException:输入字符串的格式不正确

请帮忙，我被卡住了。我有一个获取和填充网格的存储过程。我尝试在命令参数中传递一个数字值，然后根据我的标题得到未处理的异常。我试着查看DBML，但什么也看不到。这是我的密码：

</asp:TemplateField>
        <asp:BoundField DataField="name"  HeaderText="Player" />
        <asp:BoundField DataField="dsc" HeaderText="Desc." />
        <asp:BoundField DataField="cond" HeaderText="Cond." />
        <asp:BoundField DataField="maker" HeaderText="Make" />
        <asp:BoundField DataField="year" HeaderText="Year" />
        <asp:BoundField DataField="price" HeaderText="Price" DataFormatString="{0:C}"/>      
        <asp:BoundField DataField="qty" HeaderText="Qty." />
        <asp:TemplateField HeaderText="Buy">
            <ItemTemplate>
                <asp:Button ID="Button2" runat="server" Text="Buy" ToolTip="Add to Cart" OnClientClick="GridView1_SelectedIndexChanged" CommandArgument='<% #Eval("name") + "," + Eval("price") + "," + Eval("pic") %>'></asp:Button>
            </ItemTemplate>
        </asp:TemplateField>

提前感谢

鉴于

价格

是某种货币数字格式，在连接按钮

命令参数

时，需要将其转换为字符串

<asp:Button ... CommandArgument='<% #Eval("name") + "," 
+ Eval("price").ToString() + ","
+ Eval("pic") %>'>

单击按钮2时是否会发生错误？是否确定问题不在于数据绑定（是否尝试删除

DataFormatString

属性）？

<asp:Button ... CommandArgument='<% #Eval("name") + "," 
+ Eval("price").ToString() + ","
+ Eval("pic") %>'>
