The following code snippet will to hide the value associated with gridview column.

                            CellPadding="4" ForeColor="#333333" GridLines="None" Width="100%" Height="272px" Style="font-family: Consolas">
                            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
                            <Columns>
                                <asp:TemplateField HeaderText="Data 1">
                                    <ItemTemplate>
                                        <asp:Label ID="lblId" runat="server" Text='<%# Bind("id") %>' Visible="false"></asp:Label>
                                        <asp:Label ID="lblData1" runat="server" Text='<%# Bind("data1") %>'></asp:Label>
                                    </ItemTemplate>
                                </asp:TemplateField>
                                <asp:TemplateField HeaderText="Data 2">
                                    <ItemTemplate>
                                        <asp:Label ID="lblData2" runat="server" Text='<%# Bind("data2") %>'></asp:Label>
                                    </ItemTemplate>
                                </asp:TemplateField>
                            </Columns>
                        </asp:GridView>


The id column is associated with non visible label. So you can access the data that is binded with this label.

Use this code

<asp:GridView ID="GridView1" runat="server" CssClass="GridViewStyle"
        DataKeyNames="id" AutoGenerateColumns="False" OnRowDeleting="DeleteRecord"
               AllowPaging="True" AllowSorting="true" PageSize="15"
          OnPageIndexChanging="ChangePage" OnSorting="SortRecords">
            
           <Columns>
           <asp:BoundField DataField="id" HeaderText="S No" ReadOnly="True"  SortExpression="id" Visible="false" />

You can get the row by using the GridViewDeletedEventArgs.RowIndex and from the row access the cell.
void GridView_RowDeleted(Object sender, GridViewDeletedEventArgs e)
{
    int id = gridView.Rows[e.RowIndex].Cells["id"].Text;
}

This is the code snippet, you can enhance and use as you require. Just handle the row-editing event in code-behind.

<pre lang="xml">asp:GridView ID="gvwTest" runat="server" CssClass="display" AutoGenerateColumns="False" DataKeyNames="id" OnRowEditing="gvwTest_RowEditing" Width="100%">
    <columns>
        <asp:boundfield datafield="code" headertext="Code" itemstyle-width="75px" xmlns:asp="#unknown" />
        <asp:boundfield datafield="name" headertext="Name" xmlns:asp="#unknown" />
        <asp:commandfield showeditbutton="True" itemstyle-width="50px" xmlns:asp="#unknown" />
    </columns
