I want to use jQuery to select an option, say the 3th item, in a DropDownList by clicking a button, then have the DropDownList box change it's value, say '44'.
<asp:DropDownList ID="DropDownList2" runat="server"
onselectedindexchanged="DropDownList2_SelectedIndexChanged">
<asp:ListItem Selected="True">SELECT</asp:ListItem>
<asp:ListItem Value="1">23</asp:ListItem>
<asp:ListItem Value="2">32</asp:ListItem>
<asp:ListItem Value="3">44</asp:ListItem>
<asp:ListItem Value="4">61</asp:ListItem>
</asp:DropDownList>
