Start by looking at your data source: the chances are that you are storing your date values in strings (or returning them in strings when t=you fetch them into your datatable) instead of using the correct datatype (DateTime for C#, DATETIME for SQL).
As a result, the comparison which is used for sorting is string based - which stops at the first distinct character and uses that as the result for the whole comparison.
So "12-April-2015" will be before "12-February-1999" because 'A' is before 'F' - teh erst of the string is ignored.

Sort out your data source! And if it's a Database, never store date or numeric values in strings - it always causes major problems when you try to use the actual data!

Solution 2

try this

XML

table.Columns.Add("dateValue", typeof(DateTime?));

   var orderedRows = from row in dt.AsEnumerable()
                     orderby  row.Field<DateTime>("Date")
                     select row;
   DataTable tblOrdered = orderedRows.CopyToDataTable();
