Question

I am using:

if (RadioButtonList_VolunteerType.SelectedItem != null) 

or how about:

if (RadioButtonList_VolunteerType.Index >= 0) 

or how about (per Andrew Hare’s answer):

if (RadioButtonList_VolunteerType.Index > -1) 

To those who may read this question, the following is not a valid method. As Keltex pointed out, the selected value could be an empty string.

if (string.IsNullOrEmpty(RadioButtonList_VolunteerType.SelectedValue)) 

Answer 1

In terms of readability they all lack something for me. This seems like a good candidate for an extension method.

public static class MyExtenstionMethods  {      public static bool HasSelectedValue(this RadioButtonList list)    {     return list.SelectedItem != null;   } }   ...  if (RadioButtonList_VolunteerType.HasSelectedValue) {  // do stuff }
