    Bind Two Fields into One Database Field

    I have a details view where I have a date textbox and a time textbox. I am using a dataset to insert and update to the database. I need to combine the date and time textboxes to a single parameter to be entered into the database to a datetime field. My detailsview and dataobject are below. Help is appreciated.

    Code:
    <asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="training_id"
            DataSourceID="ObjectDataSource1" Height="50px" Width="125px">
            <Fields>
                <asp:TemplateField HeaderText="Type">
                    <EditItemTemplate>
                        <asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource1"
                            DataTextField="session_type_name" DataValueField="session_type_name" AppendDataBoundItems="True" SelectedValue='<%# Bind("training_type") %>'>
                            <asp:ListItem Selected="True" Value="NULL">Select Training Type</asp:ListItem>
                        </asp:DropDownList><asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:UserConferenceConnectionString %>"
                            SelectCommand="SELECT [session_type_name] FROM [training_session_type]"></asp:SqlDataSource>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# Eval("training_type") %>'></asp:Label>

    Why not store the value as one attribute, as in date/time field in the database table, therefore, eliminating the need to pull in the value from two separate text boxes? It will simplify the design and make inserting/updating/deleting that table and associated attribute much easier.
