According to your comments I understood your mission . You can solve this by creating Hidden Field for getting Id of table and you can access this id when the checkbox is checked. Then do update on the basis of id. Here I am updating name column of grid view.

Sample: WebForm1.aspx

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowCommand="GridView1_RowCommand" OnRowEditing="GridView1_RowEditing">
            <Columns>
                <asp:TemplateField HeaderText="name">
                    <ItemTemplate>
                        <asp:Label ID="lblUpdate" runat="server" Text= '<%#Eval("name") %>'></asp:Label> 
                        <asp:CheckBox ID="chkbox" runat="server" />
                         <asp:HiddenField ID="HiddenField1" runat="server" Value='<%#Eval("ID") %>' />
                    </ItemTemplate>
                </asp:TemplateField>

WebForm1.aspx.cs

protected void btnSave_Click(object sender, EventArgs e)        {

        foreach (GridViewRow row in GridView1.Rows)
        {

            if (row.RowType==DataControlRowType.DataRow)
            {
                CheckBox chkbox = (CheckBox)row.Cells[0].FindControl("chkbox");
                HiddenField hdID = (HiddenField)row.Cells[0].FindControl("id");
                Label lbl = (Label)row.Cells[0].FindControl("lblUpdate");
                if (chkbox!=null)
                {
                    if(chkbox.Checked)
                    {
                        string Id = hdID.Value;
                        //now update name...  here by the help of this RowId===> Id
                    }
                }
            }

        }

Note here Cells[0] means first TemplateField data. And I have used this because I have placed all name field and checkbox field in first templatefield.

I think this will help you. :)
