Binding RadioButtonList to List<T> and setting DataValueField Proprty

Question

Hello..

I have a class called "Answer" includes:

int ID;

String Text;

And I have a list of them like this:

List<Answer> myList;

in the web page, I have RadioButtonList that I want to bind data from the list above, so I've done:

AnswersButtonList.DataSource = myList;
AnswersButtonList.DataTextField = "Text";
AnswersButtonList.DataValueField = "ID";
AnswersButtonList.DataBind();

but the DataValueField didn't bind well! I feel I'm doing that in a wrong way, waiting your help :)

Answer 1

perhaps try changing your ID property to string.

according to documentation here DataValueField is a string property:

Answer 2

This works for me

Answer class has following properties

public string AnswerID
{
    get { return theAnswerID; }
    set { theAnswerID = value; }
}

public string Text
{
    get { return theText; }
    set { theText = value; }
}

then create your list and bind. If it still isn't working then I'd bind to a gridview to see what is getting churned out by your list.
