problem with radio button in asp.net

[priyajee]

Hi all,
I have an issue with radiobuttonlist in asp.net.
Under selectedindexchanged event of radiobutton list, i'm doing marks calculation.
Actually speaking,that event should run only one time..but even after finishing the calculation, selectedindexchanged event is again loading so that my marks result is showing wrong..
Even i tried with page.ispostback condition also..no correct results came..

Plz help to do this..

Thanks in advance,
Priyajee

Hey,

Can you show the code that you are using?

Does the RadioButtonList AutoPostBack to the server, or do you have a Submit Button?

Protected Sub RadioButtonList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadioButtonListQ1.SelectedIndexChanged

        If RadioButtonListQ1.SelectedItem.Value = "radQ1a" Then
           
            Session("marks") = 1
        Else
            Session("noofwronganswers") = 1

        End If

    End Sub
    Protected Sub RadioButtonListQ2_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadioButtonListQ2.SelectedIndexChanged

        If RadioButtonListQ2.SelectedItem.Value = "radQ2b" Then
            Session("marks") = Session("marks") + 1
        Else
            Session("noofwronganswers") = Session("noofwronganswers") + 1

        End If

    End Sub

    Protected Sub cmdFinishtest_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdFinishtest.Click
      
         lblmarksscroed.Text = "Marks Scored:" & Session("marks")
        lblnoofwrong.Text = "No.of Wrong Answers:" & Session("noofwronganswers")
      
    End Sub

looks like you are setting up a test...

instead of using session, you can use arraylist..(static) saving server resources..

if answer is correct add 1 to array list./..

on submit button calculate sum up all the 1's..

and get the output..
-------------------------------------------------------------------

in your code i guess you need to typecast the value of session..

in order to get the sum...

hope that helps..

Hey,

You still haven't really answered the question.

Is your RadioButtonList configured to post back to the server each time? If not, you have to take into consideration that ASP.Net will "remember" each change to the RadioList, and when you eventually post back to the server, it will do each SelectedChanged Event.

Can you define exactly what you want to achieve, perhaps with the aid of screen shots, and I am sure that we will be able to help you.
