how to fill grid view with dataset - c#-4.0

Question

i have done code to fill up grid view with data set.
just look at :
public void FillGrid(string StartAlpha, string CommandName, string ColumnName, string SearchText)
{
using (DataClassesDataContext db = new DataClassesDataContext())
{
int userid = db.Users.Where(u => u.EmailAddress.Equals((String)Session["EmailID"])).Select(u => u.Id).SingleOrDefault();
var sms = Enumerable.Repeat(new
{
Id = default(int),
Title = string.Empty,
Body = string.Empty,
FromUser = string.Empty,
ToUser = string.Empty,
SentDateTime = default(DateTime?),
IsMedia = default(bool),
CreatedDate = default(DateTime),
}, 1).ToList();
DataSet myDataSet = new DataSet();
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Id", typeof(string)));
dt.Columns.Add(new DataColumn("Title", typeof(string)));
dt.Columns.Add(new DataColumn("Body", typeof(string)));
dt.Columns.Add(new DataColumn("FromUser", typeof(string)));
dt.Columns.Add(new DataColumn("ToUser", typeof(string)));
dt.Columns.Add(new DataColumn("SentDateTime", typeof(DateTime)));
dt.Columns.Add(new DataColumn("IsMedia", typeof(bool)));
dt.Columns.Add(new DataColumn("CreatedDate", typeof(DateTime)));

What wrong with my Code?????
please help me to throughout this problem.....

Answer 1

Looks like you have a spelling error SentDatetTime -> SentDateTime:
if (item.SentDateTime != null)
{
dr["SentDateTime"] = item.SentDateTime;
}
else
{
dr["SentDateTime"] = DBNull.Value;
}
