Hi sth_syed,

GridView check one by one.

Code below is for your reference :

<asp:GridView ID="GridView1" runat="server" HeaderStyle-BackColor="#3AC0F2" HeaderStyle-ForeColor="White"
            AutoGenerateColumns="false" OnRowDataBound="OnRowDataBound">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:CheckBox ID="chkRow" runat="server" AutoPostBack="true" OnCheckedChanged="chkRow_CheckedChanged"   />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150" />
                <asp:TemplateField HeaderText="Country" ItemStyle-Width="150">
                    <ItemTemplate>
                        <asp:Label ID="lblCountry" runat="server" Text='<%# Eval("Country") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

server side :

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!this.IsPostBack)
            {
                DataTable dt = new DataTable();
                dt.Columns.AddRange(new DataColumn[2] { new DataColumn("Name"), new DataColumn("Country") });
                dt.Rows.Add("John Hammond", "Canada");
                dt.Rows.Add("Rick Stewards", "United States");
                dt.Rows.Add("Huang He", "China");
                dt.Rows.Add("Mudassar Khan", "India");
                GridView1.DataSource = dt;
                GridView1.DataBind();
            }


        }

        protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                if (e.Row.RowIndex ==0)
                {
                    CheckBox CheckBox1 = (e.Row.FindControl("chkRow") as CheckBox);

                    CheckBox1.Checked = true;
                }
                if (e.Row.RowIndex>1)
                {
                    CheckBox CheckBox1 = (e.Row.FindControl("chkRow") as CheckBox);

                    CheckBox1.Enabled = false;

                }
                        
            }
        }

        protected void chkRow_CheckedChanged(object sender, EventArgs e)
        {
            CheckBox chk = (CheckBox)sender;
            GridViewRow row = (GridViewRow)chk.NamingContainer;
            GridViewRow nextRow = this.GridView1.Rows[row.RowIndex+1];
            var checkbox = nextRow.FindControl("chkRow") as CheckBox;
            checkbox.Enabled = true;
        }
