I have this Code in "details.aspx":

<asp:radiobuttonlist id="UserType" runat="server" >
<asp:ListItem Value="reular">reular</asp:ListItem>
<asp:ListItem Value="advance">reular</asp:ListItem>
</asp:radiobuttonlist>

In "details.aspx.vb" I have this code

Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim number as integer= request.form("numType")

If number="1" then
  ' here come the mising code
else
  ' here come the mising code
end if

END SUB


In the mising code I want to write that if numbet="1" so I want that in my radiobuttonlist, the first Radio will be checked and Else the seconed will be checked.

How to do it???

Radiobuttonlist has 0 based index. So what you can do is something like this(Code in C#)

if(number >= 1)
   UserType.SelectedIndex = number-1;

This should check the Radiobuttonlist according to the number. So if number is 1 it will check first item, if number is 5 it will check fifth item.

Hope it helps
