                            </ItemTemplate>
                        </asp:Repeater>

I want to get the selected value from RadioButtonList.

Answer 1

You have to loop through repeater and find each RadioButtonList as

foreach (RepeaterItem item in Rep_CatQuestion.Items)
{
    string value = (item.FindControl("Rep_Answer") as RadioButtonList).SelectedValue;
    ...
}
