get a value from a radio button

Question

I have a radio button in my .aspx page and in the code behind I have written the following:

if (rbOnlyCreatedorUpdated.Checked == true)
{
    searchObject.CreatedOrUpdatedOnValidDate = SearchCritera.OnlyCreatedOrUpdated;
}
else if (rbOnlyOld.checked == true)
{
    searchObject.CreatedOrUpdatedOnValidDate = SearchCritera.OnlyOld;
}
else
{
    searchObject.CreatedOrUpdatedOnValidDate = SearchCritera.AllChanged;
}

And I really dislike the above. It feels clumsy and unclean. I would like a value to be returned by the radio button itself (named rbOnlyCreatedOrUpdatedOnValidDate, ie the GroupName).

Is it possible or is the above the correct way to get the value?

Answer 1

If you use a RadioButtonList control, you can access the selected radiobuttons value by using IdOfRadioButtonList.SelectedValue . This will give you a string, so you will still have to do the conversion to one of the SearchCriteria class' properties yourself...

If it makes you feel any better, you can make it into a ternary operator, like so:

searchObject.CreatedOrUpdatedOnValidDate = 
    rbOnlyCreatedorUpdated.Checked ? SearchCritera.OnlyCreatedOrUpdated : 
    rbOnlyOld.checked ? SearchCritera.OnlyOld : 
    SearchCritera.AllChanged;
