This might provides you some of the idea:

Example code:

XML

<asp:Button ID="Button_Save" runat="server" Text="Save" OnClick="Button_Save_Click" />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
    <Columns>
        <asp:BoundField DataField="id" HeaderText="ID" />
        <asp:TemplateField HeaderText="Pending Account">
            <ItemTemplate>
                <asp:DropDownList ID="dropAction" runat="server"></asp:DropDownList>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>
