Select value from previous page

Question

HI Guys,
I populate this select using C# code.
When I submit this form how do I get the selected value on the the new page?

<form >
<tr bgcolor="#ffffff">
                        <td style="width: 134px">
                            Device Type*</td>
                        <td>
                            <select id="selDevice" runat="server" name="selDevice">
                                <option value="" selected="selected" > [ Device Type ] </option>
                            </select>
                        </td>
                    </tr>
</form>


thanks Guys
