Page Load is first then Radiobuttonlist .selecteditemCh anged, can we change this?

[ricardo.sobral.santos]

Hello,

I am trying to get the value of the radiobuttonlist . The problem is
that I need it to be unselected at every page load. The
radiobuttonlist is set to autopostback (true).
My idea is simple. When I select a value, I get it, insert something
into the database with that value and the page loads again with
different data. Imagine a questionnaire and every page load a random
question would be load on screen and when the user clicks the
radiobutton list, I get the value, insert into the database and only
after I do the page_load again. Is there any way of doing this without
a button, and setting the selecteditemcha nged to fire first then the
page_load?

Tks for the help.

The code is simple!
'My Page load is working just the way I want it!
Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArg s) Handles Me.Load

If Not Page.IsPostBack Then
RadioButtonList 1.ClearSelectio n() ' I need it to be clear
each time!
leftPanel.Visib le = False
Dim users As New ArrayList
users = User_.ArrayOfUs ers
Session.Add("us ers", users)
Session.Add("i" , 0)

i = 0
details = User_.getQuesti ons(users.Item( i))
Image.ImageUrl = details(1).ToSt ring
lblLastChecked. Text = details(3).ToSt ring
details.Clear()
'users.Clear()
Else
'RadioButtonLis t1.ClearSelecti on()
i = CType(Session(" i"), Integer)

Dim users_tmp As ArrayList
users_tmp = CType(Session(" users"), ArrayList)

If (i < users_tmp.Count - 1) Then
detailsAfterRat ing =
User_.getQuesti ons(users_tmp.I tem(i))
details = User_.getQuesti ons(users_tmp.I tem((i + 1)))

Image.ImageUrl = details(1).ToSt ring
lblLastChecked. Text = details(3).ToSt ring

RatedImage.Imag eUrl = detailsAfterRat ing(2).ToString
lblRating.Text = detailsAfterRat ing(5).ToString
lblPastRate.Tex t = Session("youRat ed")
i = (i + 1)
Session.Add("i" , i)
'details.Clear( )
'detailsAfterRa ting.Clear()
leftPanel.Visib le = True
Else
Response.Redire ct("Homepage.as px")
End If
End If
End Sub



'This works fine, but only after the page_load. So the first time is
ok, but the second time I need it to be clear and to do something
before it goes to page_load again.

Protected Sub RadioButtonList 1_SelectedIndex Changed(ByVal sender
As System.Object, ByVal e As System.EventArg s) Handles
RadioButtonList 1.SelectedIndex Changed
Dim answer As String
answer = RadioButtonList 1.SelectedValue .ToString

'Code for inserting into database...

End Sub
Tks for all the help.

Simply redesign it a little bit, as per

Sub Page_Load(...)

If Not Page.IsPostBack Then
LoadNewQuestion ()
End If

End Sub

Sub RadioButtonList 1_SelectedIndex Changed
'Code for inserting into database...
......
LoadNewQuestion ()
End Sub

Sub LoadNewQuestion ()
RadioButtonList 1.ClearSelectio n()
' Loading new question
.......
End Sub
