Question

The current code: manually setting.

<asp:DropDownList ID="Question" runat="server">
  <asp:ListItem>What is the city of your birth?</asp:ListItem>
  <asp:ListItem>What school did you attend for sixth grade?</asp:ListItem>
  <asp:ListItem>What is your maternal grandmother's maiden name?</asp:ListItem>
  <asp:ListItem>Where were you when you had your first kiss?</asp:ListItem>
  <asp:ListItem>Who was your childhood hero?</asp:ListItem>
</asp:DropDownList>

In the configuration file, if I put items in

<appSettings>
    <add key="Question1" value="What is the city of your birth?" />

Then how can I retrieve them from code?

Answer 1

You can do something like this:

int i = 1;

string question = null; 

do {
   question = System.Configuration.ConfigurationManager.AppSettings["Question" + i.ToString()]; 

   if (question != null) {
     Question.Items.Add(new ListItem(question, i.ToString()));
     i++;
   }
} while (question != null);
