ASP.NET - 1st character is showing capital in Gridview Row!

Hi All,
I am bind a gridview and 1st character is showing capital.
From code behind I am sending roman numbers like (ii)
and in Gridview It is showing like (Ii),
How we manage same at gridview. I am taking asp bound fields
in gridview.

Hi,
     Please check your code ,is any where you are converting the text to uppercase like...  e.Row.Cells(0).Text.ToUpper

I am not converting anywhere. and i am send in lower case and through firebug it showing lower in source code but in browser it showing 1st upper.

Share your code if possible....

private string ConvertLowerCaseRoman(int number)
      {
        string strLowerCaseRoman = string.Empty;
        if (number == 1)
        {
          strLowerCaseRoman = "i";
        }
        else if (number == 2)
        {
          strLowerCaseRoman = "ii";
        }
        else if (number == 3)
        {
          strLowerCaseRoman = "iii";
        }
        else if (number == 4)
        {
          strLowerCaseRoman = "iv";
        }
        else if (number == 5)
        {
          strLowerCaseRoman = "v";
        }
        else if (number == 6)
        {
          strLowerCaseRoman = "vi";
        }
        else if (number == 7)
        {
          strLowerCaseRoman = "vii";
        }
        else if (number == 8)
        {
          strLowerCaseRoman = "viii";
        }
        else if (number == 9)
        {
          strLowerCaseRoman = "ix";
        }
        else if (number == 10)
        {
          strLowerCaseRoman = "x";
        }
        else
        {
          strLowerCaseRoman = "x" + number.ToString();
        }
        return strLowerCaseRoman;

      }
