Hallo,
I have a radiobuttonlist control that is added on a custom Web User Control. This control has a property that exposes the SelectedIndex property of the embedded radiobuttonlist. When running this in IE, behaviour is as I would expect it. If I select an item and do a postback, the page remembers my selection when reloading, and the SelectedIndex property of my control returns the correct value. When running this in Firefox 3, I always get a -1 for the SelectedIndex prop, and the page does not remember my selection when reloading. If I add a radiobuttonlist directly on to an ASPX page, behaviour is as expected. Only fails in Firefox when the control is on a custom Web User Control. Below I will paste the aspx, ascx, and their respective code behind files. ..Net Framework 3.5. Any advice would be appreciated. Thanks Paul 1.

its a bug in IE, it should send -1 also.
you are loading the user control too late in the page lifecycle, so that it does not exist when postback data is applied. the proper place to load dynamic controls is in the CreateChildControls method (which was designed for this, or OnInit in a pinch) -- bruce (sqlwork.com) "Paul" wrote: > Hallo, > > I have a radiobuttonlist control that is added on a custom Web User Control. > This control has a property that exposes the SelectedIndex property of the > embedded radiobuttonlist. > > When running this in IE, behaviour is as I would expect it.

Hi,
moving the code to create the control to OnInit or CreateChildControls doesn't change the thing, ASP.NET is able to load postback data for controls loaded in Page_Load (postback data loading happens in two steps once before and once after Load - you can cofirm that by checking page trace). By the way, for testing purposes maybe OK, but don't use MSgBox in ASp.NET in production as it shows the MSgBoxes only on the server machine... The issue itself relates that you add vbTab to the ListItem's Text in code: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Question_TXT.Text = "Pick One" Answer_RBL.Items(0).Text = vbTab & "First" Answer_RBL.Items(1).Text = vbTab & "Second" End Sub Remove the vbTab appendings and you'll note the thing starts to work just fine (with control loaded in Page_Load, although in practise doing it in Init or CreateChildControls eases certain things in the long run. So I suppose it relates to other browser dealing with the tab... -- Teemu Keiski AspInsider, ASP.NET MVP http://blogs.aspadvice.com/joteke http://teemukeiski.net "Paul" <> wrote in message news:6281D426-7F77-46DD-AFA8-... > Hallo, > > I have a radiobuttonlist control that is added on a custom Web User > Control. > This control has a property that exposes the SelectedIndex property of the > embedded radiobuttonlist. > > When running this in IE, behaviour is as I would expect it.

Thanks for your Teemu's informative inputs.
Seems the problem is related to the firefox 3's handling on <select> options which contains tab chars. BTW, I agree that "OnInit" and "CreateChildControls" are the prefered place for dynamic controls though it may not address the problem here.

Hi Teemu,
Fantastic. So simple, and I spent so much time trying to track this down. Your help is appreciated. Thanks as well Bruce and Steven. By the way, in the sample I load the controls in the Page Load event, but in my actual page I load it in PreInit.
