Hi,

You can do it in 2 ways, one is in database wise and another one is in C# code wise.

If you want to filter the result only date wise then you should convert the result set into date format only, as per output provide by you it is in datetime format.

If you want to convert the result in date format using SQL query refer below sample query for the same.


select convert(date, getdate())

If you want to convert the datatable result in date format, using .ToString() you can convert the result as you want.


foreach(DataRow dr in dt.Rows)
{
          string date=dr["datefield"].ToString("dd/MMM/yyyy");
}

After get the data in your expected format then filter it.

I provide you the sample you have to recode as you want.

I have below method to filter date from datatable, see below snippet, it filters using LINQ


private DataTable FilterTable(DataTable table, DateTime startDate, DateTime endDate)
{
    var filteredRows =
        from row in table.Rows.OfType<DataRow>()
        where (DateTime)row[0] >= startDate
        where (DateTime)row[0] <= endDate
        orderby (int)row[1] descending 
        select row;
    var filteredTable = table.Clone();
    filteredRows.ToList().ForEach(r => filteredTable.ImportRow(r));
    return filteredTable;
 }

I have not try it though.

Hi

you can try this code



DataTable dt = new DataTable();
            dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id"), new DataColumn("Name"), new DataColumn("LastUpdateDate") });
            dt.Rows.Add(1, "harni", "03/25/2016 09:07:20");
            dt.Rows.Add(2, "seetha", "03/25/2016 09:07:20");
            dt.Rows.Add(3, "vision", "03/26/2016 09:06:20");
            dt.Rows.Add(4, "abc", "03/24/2016 09:09:20");
            dt.Rows.Add(5, "def", "03/27/2016 09:07:20");
            dt.Rows.Add(6, "ghi", "03/27/2016 09:07:20");
            dt.Rows.Add(7, "jkl", "03/28/2016 09:07:20");
            dt.Rows.Add(8, "mno", "03/28/2016 09:07:20");
            dt.Rows.Add(9, "pqr", "07/29/2016 09:07:20");

            string date = "03/25/2016";

            //dt.Select("LastUpdateDate like '%" + date + "%'");
            //dt.DefaultView.RowFilter = " LastUpdateDate like '% " + date + " %'";
            //dt.DefaultView.RowFilter = " LastUpdateDate= #03/25/2016# ";
            DataTable Dt = new DataTable();
            DataView dv = new DataView();
            dv = dt.DefaultView;
            dv.RowFilter = " LastUpdateDate >=#'" + date + "' And  LastUpdateDate<= #'" + date + "'";
            Dt = dv.ToTable();
