Grade Does Not Increment!

[mercea]

Hi all,
i have a web page which contains a gridview. On this gridview, the user uses a set of radiobuttonlists to select an option. the selected option is then to be compared with the data in a table. I draw out this data using a dataset table adapter. i want to compare the two values and if they are the same, increment Grade by 1. This is my code below. When i run it, grade always remains at zero. Can you please help me check why its not working? thanks

 string studentAnswer;
    string lecturerAnswer;
    int Grade = 0;
    int i = 1;
 
      public void Button1_Click(object sender, EventArgs e)
    {
        DataSet1TableAdapters.QuestionsTTableAdapter adapter = new DataSet1TableAdapters.QuestionsTTableAdapter();
        DataSet1.QuestionsTDataTable questions = adapter.GetData();
        DataSet1.QuestionsTRow rowT = questions[i];
 
 
        foreach ( GridViewRow row in GridView1.Rows ) 
        {
            lecturerAnswer = rowT.Answers;
            i++;
            RadioButtonList radiolist = (RadioButtonList)row.FindControl("radlist");
 
            if (radiolist != null  )
            {
                foreach (ListItem litem in radiolist.Items)
                {
                    if (litem.Selected)
                    {
                        studentAnswer = radiolist.SelectedValue.ToString();
                    }     
                }
            }
            if (studentAnswer == lecturerAnswer)
            {
                Grade++;
            }
            else
            {
                Grade= Grade + 0;
            }
        }
        Label1.Text = "You have Scored " + Grade;
    }

            }
                  }
        Label1.Text = "You have Scored " + Grade;
    }
 

See bolded code above. I think the reason that Grade was not being incremented is because the only studentAnswer being compared was the very last studentAnswer in radiolist.Items.

Place this code

if (studentAnswer == lecturerAnswer)
                    {
                        Grade++;
                     }
                     else
                     {
                         Grade= Grade + 0;
                      } 

after this conditional statement.

 if (litem.Selected)
                    {
                        studentAnswer = radiolist.SelectedValue.ToString();
                    }
