I have a code behind for my default.aspx page.
I am using a databaind control (RadioButtonList) for options a user would choose from.
some where in the code, i have created a protected function in which i try to reference the list item value of my radio control the user has selected.
when the page submits, i get the following error on this line:
System.NullReferenceException: Object reference not set to an instance of an object.
Here's the line that generates that error:
userChoice = Convert.ToSByte(radioListContainer.SelectedItem.Va lue);
I don't know what i am missing or doing wrong?
Any help please?!
Many thanks
