Very Simple, but I'm lost

Hi,

I am very new to asp.net and have been pulling my hair out to find a solution to something very simple. I have been using this zillow api widget:

aspx:

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Zillow.aspx.cs" Inherits="Caffeinated.TestPages.ZillowDemoPage" %>
<%@ Import Namespace="Caffeinated.TestPages" %>
<%
ZillowRateSummary MortgageRates = GetRateSummary();
%>
<html>
<body>
<style>
* { font-family:Myriad,Arial,Helvetica,sans-serif; font-size: 9pt }
a { color: blue; text-decoration: none }
a:hover { text-decoration: underline }
.falling { color: green }
.rising { color: red }
.steady { color: orange }
#morgagerates { width: 200 }
</style>
<div class="hslice" id="morgagerates">
<b class="entry-title">Mortgage Rates</b>
<table>
<tr>
    <td align="left"></td>
    <td align="center">Today's<br>Rates</td>
    <td align="center">Last<br>Week</td>
</tr>
<tr>
    <td align="left"><a href="http://www.zillow.com/30_Year_Fixed_Mortgage_Rates/">30 Year Fixed</a></td>
    <td class="<% =GetTrendClass(MortgageRates.Is30YearFixedDown)%>" align="center"><% =MortgageRates.Today30YearFixed %>%</td>
    <td class="<% =GetTrendClass(MortgageRates.Is30YearFixedDown)%>" align="center">
        <% =GetTrendIcon(MortgageRates.Is30YearFixedDown)%><% =MortgageRates.LastWeek30YearFixed %>%
    </td>
</tr>
<tr>
    <td align="left"><a href="http://www.zillow.com/15_Year_Fixed_Mortgage_Rates/">15 Year Fixed</a></td>
    <td class="<% =GetTrendClass(MortgageRates.Is15YearFixedDown)%>" align="center"><% =MortgageRates.Today15YearFixed %>%</id>
    <td class="<% =GetTrendClass(MortgageRates.Is15YearFixedDown)%>" align="center">
        <% =GetTrendIcon(MortgageRates.Is15YearFixedDown)%><% =MortgageRates.LastWeek15YearFixed %>%
    </td>
</tr>
<tr>
    <td align="left"><a href="http://www.zillow.com/5-1_ARM_Mortgage_Rates/">5.1 ARM</a></td>

				Response.Close();

            return zrs;
        }
    }
}

I simply want to add a drop downon the default.aspx page to select a state, which will change the value in on const string state = "ma"; on the code behind page.

that's it I have been doing some searching , but not ever sure what to search for.. Thank you for any help

I found this DropDownList online, so you can just copy and paste this in your aspx page wherver you want. I have set it to AutoPostBack="true", which means that when you change the state, the page will post back and your server code will be executed.

<asp:DropDownList ID="DropDownListState" runat="server" AutoPostBack="true">
	<asp:ListItem Value="AL">Alabama</asp:ListItem>
	<asp:ListItem Value="AK">Alaska</asp:ListItem>
	<asp:ListItem Value="AZ">Arizona</asp:ListItem>
	<asp:ListItem Value="AR">Arkansas</asp:ListItem>
	<asp:ListItem Value="CA">California</asp:ListItem>
	<asp:ListItem Value="CO">Colorado</asp:ListItem>
	<asp:ListItem Value="CT">Connecticut</asp:ListItem>
	<asp:ListItem Value="DC">District of Columbia</asp:ListItem>
	<asp:ListItem Value="DE">Delaware</asp:ListItem>
	<asp:ListItem Value="FL">Florida</asp:ListItem>
	<asp:ListItem Value="GA">Georgia</asp:ListItem>
	<asp:ListItem Value="HI">Hawaii</asp:ListItem>
	<asp:ListItem Value="ID">Idaho</asp:ListItem>
	<asp:ListItem Value="IL">Illinois</asp:ListItem>
	<asp:ListItem Value="IN">Indiana</asp:ListItem>
	<asp:ListItem Value="IA">Iowa</asp:ListItem>
	<asp:ListItem Value="KS">Kansas</asp:ListItem>
	<asp:ListItem Value="KY">Kentucky</asp:ListItem>
	<asp:ListItem Value="LA">Louisiana</asp:ListItem>
	<asp:ListItem Value="ME">Maine</asp:ListItem>
	<asp:ListItem Value="MD">Maryland</asp:ListItem>
	<asp:ListItem Value="MA">Massachusetts</asp:ListItem>
	<asp:ListItem Value="MI">Michigan</asp:ListItem>
	<asp:ListItem Value="MN">Minnesota</asp:ListItem>
	<asp:ListItem Value="MS">Mississippi</asp:ListItem>
	<asp:ListItem Value="MO">Missouri</asp:ListItem>
	<asp:ListItem Value="MT">Montana</asp:ListItem>
	<asp:ListItem Value="NE">Nebraska</asp:ListItem>
	<asp:ListItem Value="NV">Nevada</asp:ListItem>
	<asp:ListItem Value="NH">New Hampshire</asp:ListItem>
	<asp:ListItem Value="NJ">New Jersey</asp:ListItem>
	<asp:ListItem Value="NM">New Mexico</asp:ListItem>
	<asp:ListItem Value="NY">New York</asp:ListItem>
	<asp:ListItem Value="NC">North Carolina</asp:ListItem>
	<asp:ListItem Value="ND">North Dakota</asp:ListItem>
	<asp:ListItem Value="OH">Ohio</asp:ListItem>
	<asp:ListItem Value="OK">Oklahoma</asp:ListItem>
	<asp:ListItem Value="OR">Oregon</asp:ListItem>
	<asp:ListItem Value="PA">Pennsylvania</asp:ListItem>
	<asp:ListItem Value="RI">Rhode Island</asp:ListItem>
	<asp:ListItem Value="SC">South Carolina</asp:ListItem>
	<asp:ListItem Value="SD">South Dakota</asp:ListItem>
	<asp:ListItem Value="TN">Tennessee</asp:ListItem>
	<asp:ListItem Value="TX">Texas</asp:ListItem>
	<asp:ListItem Value="UT">Utah</asp:ListItem>
	<asp:ListItem Value="VT">Vermont</asp:ListItem>
	<asp:ListItem Value="VA">Virginia</asp:ListItem>
	<asp:ListItem Value="WA">Washington</asp:ListItem>
	<asp:ListItem Value="WV">West Virginia</asp:ListItem>
	<asp:ListItem Value="WI">Wisconsin</asp:ListItem>
	<asp:ListItem Value="WY">Wyoming</asp:ListItem>
</asp:DropDownList>

Then just use the value selected in your code like:

DropDownListState.SelectedValue

Max
