if trying accomplish selected value, change this

<select id="letter" runat="server">     <option>a</option>     <option>b</option>     <option>c</option> </select> 

for this

<asp:dropdownlist id="letter" runat="server" >     <asp:listitem text="a" value="a"></asp:listitem>     <asp:listitem text="b" value="b"></asp:listitem>     <asp:listitem text="c" value="c"></asp:listitem> </asp:dropdownlist> 

and selected value this

string selectedvalue = letter.selectedvalue;
