Hi ,
I am creating a web application in ASP.NET and C#.
I have 4 textboxes for Choice1, Choice 2, Choice3 and Choice4.
And, Radiobuttonlist with 4 items, A,B,C,D
I want if user select option A in radiobuttonlist, then its value should be equal to choice 1 textbox, if user select Option B in radiobuttonlist, then its value should be equal to Choice 2 textbox and so on..
i tried if else loop for this, but whatever option i select, radiobuttonlist selected index always remains 0.
How to get selected index of radiobuttonlist??

Hi,

Code in design page...

ASP.NET

<asp:radiobuttonlist id="RadioButtonList1" runat="server" autopostback="True" xmlns:asp="#unknown">
            onselectedindexchanged="RadioButtonList1_SelectedIndexChanged">
        <asp:listitem>Choice1</asp:listitem>
        <asp:listitem>choice2</asp:listitem>
        <asp:listitem>choice3</asp:listitem>
        <asp:listitem>choice4</asp:listitem>
        </asp:radiobuttonlist>

I raise server event on index changed by user.

event code for retrieving selectedindex from raised event

C#

protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
    int i = RadioButtonList1.SelectedIndex;
}

If you changed index this event'll be raise thn check for index values.
Just now I worked on it.it works fine for me.

If any doubts just post with your code it can helps to solve your problem

I hope you understand what I said.

All the best.

Solution 3

It seems that you're populating the RadioButtonList on the page load -
If so - make sure you surround your population of the RadioButtonList with an
If/Then/Postback block:
if not Page.IsPostBack then
' populate your RBL
end if

eg:

if (!IsPostBack)
{
loadradiobuttonlist();
}
