 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
        <Columns>
            <asp:CheckBoxField HeaderText="SELECT"  />
            <asp:BoundField DataField="ICAO" HeaderText="ICAO" />
            <asp:BoundField DataField="IATA" HeaderText="IATA" />
            <asp:BoundField DataField="AIRPORT_NAME" HeaderText="AIRPORT NAME" />
            <asp:BoundField DataField="CITY" HeaderText="CITY" />
            <asp:BoundField DataField="COUNTRY" HeaderText="COUNTRY" />
            <asp:BoundField DataField="REVISED_DATE" HeaderText="REVISED DATE" />
            <asp:BoundField DataField="EMAIL_DATE" HeaderText="EMAIL DATE" />

        </Columns>
    </asp:GridView>

Try using a <TemplateField /> instead

<asp:TemplateField>
    <ItemTemplate>
        <asp:CheckBox runat="server" ID="cbSelect"/>
    </ItemTemplate>
</asp:TemplateField>

You have to add the CheckBox to the ItemTemplate, like in Bala's example.

Take a look here http://www.asp.net/data-access/tutorials/adding-a-gridview-column-of-checkboxes-vb

CheckBoxField is designed to work with a Boolean data field. That is, in order to use the CheckBoxField we must specify the underlying data field whose value is consulted to determine whether the rendered checkbox is checked. We cannot use the CheckBoxField to just include a column of unchecked checkboxes.

Just add an ItemTemplate field and add a <asp:checkbox> to it.
