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
