Default LINQ Group and Sum


Hi, all masters.

I have a problem. I use below code;

Dim dt = New DataTable("tblEntTable")
...
...
dt.Columns.Add("DATE", GetType(Date))
dt.Columns.Add("ID", GetType(String))
dt.Columns.Add("INFORMATION", GetType(String))
dt.Columns.Add("QTY", GetType(Decimal))
dt.Columns.Add("AMOUNT", GetType(Decimal))
dt.Columns.Add("empID", GetType(Short))
bla
bla
bla
Datatable columns total 60 fields.

dt.Rows.Add
.....
.....

Dim res = dt.AsEnumerable()
.OrderBy(Function(row) row.Field(Of String)("ID"))
.GroupBy(Function(row) row.Field(Of String)("ID"))
.[Select](Function(grp) grp.First())

dtgrdClone.DataSource = res.CopyToDataTable


Code is perfect run, but not SUM Amount Fields.

How to SUM "Ammunt" Fields.

Please Help
