C# Datagridview没有'；t返回行的id

我在我的项目中插入了一个gridview，我放置了一个按钮来获取单击行的id，但每次它都返回“0”值

以下是我的gridview代码：

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" ForeColor="#333333" GridLines="None" OnRowCommand="GridView1_RowCommand">
        <AlternatingRowStyle BackColor="White" />
        <Columns>
            <asp:BoundField DataField="SubProductId" HeaderText="شماره " />
            <asp:TemplateField HeaderText="برند ">
                <EditItemTemplate>
                    <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("SubProductName") %>'></asp:TextBox>
                </EditItemTemplate>
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text='<%# Bind("SubProductName") %>'></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:ButtonField ButtonType="Image" CommandName="editrecord" HeaderText="ویرایش" ImageUrl="~/adminPortal/Images/edit.png" />
        </Columns>
        <EditRowStyle BackColor="#2461BF" />
        <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
        <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
        <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
        <RowStyle BackColor="#EFF3FB" />
        <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
        <SortedAscendingCellStyle BackColor="#F5F7FB" />
        <SortedAscendingHeaderStyle BackColor="#6D95E1" />
        <SortedDescendingCellStyle BackColor="#E9EBEF" />
        <SortedDescendingHeaderStyle BackColor="#4870BE" />
    </asp:GridView>

我最终发现，问题是因为我删除它时的“EditItemTemplate”起作用
