<asp:RadioButton /> Determining which is selected without javascript

(1/1)

h0meopathic:
I have 36 radio buttons in a form, all with the same groupName, and all with different IDs.  Is it possible to find out which ID is selected without fishing for it? Surely a dynamic control such as a radiobutton wouldn't have been made without a simple way of finding out which button was selected.

housetier:
go check out asp:RadioButtonList, it has a bunch of properties that start with "Selected"

h0meopathic:
You have to make a radiobuttonlist as follows


--- Code: HTML ---<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack="True"                    RepeatColumns="3" TextAlign="Left">                    <asp:ListItem Value="1">07:00AM-07:15AM</asp:ListItem>                     <asp:ListItem Value="2">07:15AM-07:30AM</asp:ListItem>                    <asp:ListItem Value="3">07:30AM-07:45AM</asp:ListItem>                    <asp:ListItem Value="4">07:45AM-08:00AM</asp:ListItem>                </asp:RadioButtonList>
Then add some statements to make sure its working (inside submitButton_Click). radioButton is my label

--- Code: C# ---if (RadioButtonList1.SelectedIndex > -1)        {            radioButton.Text = "<br />you selected: " + RadioButtonList1.SelectedIndex.ToString();        }        else        {            radioButton.Text = "Select a radio button";        }
Then attache it to the database like so:

--- Code: C# ---appNameComm = new SqlCommand("INSERT INTO AppointmentName (LastName, FirstName, Email, BirthDate, Slot) " +                "VALUES (@LastName, @FirstName, @Email, @BirthDate, @Slot)", conn);...appNameComm.Parameters.Add("@Slot", System.Data.SqlDbType.Int, 2);            appNameComm.Parameters["@Slot"].Value = RadioButtonList1.SelectedIndex.ToString();

be sure to check that SelectedWhatever is not null. Never trust user input and even a selected radio button is user input.
