Hello there!
Two main questions for you
1)
Following the ServerExample by Erel I managed to fill a 3 column table with a HUGE query (about 1500 rows...).
I noticed that in those example Erel uses Datatable. I digged a little bit and found out there's a new version, with some spicy things included (primarly I'm very interested in the search function).
I tried to implement the new Datatable, but I still get the "classic" one, without the marvellous search function...any tips?
2)
Also following the same example, I tried to implement the function that let you select a row and change its color, but without success.
I copied the css files (changing the table ID accordingly, of course).
Some code below

Some code below
Function that fills the table:
Sub FillTable(jq As JQueryElement, rs As ResultSet)
Dim data As List
data.Initialize
Do While rs.NextRow
Dim row As List
row.Initialize
For a = 0 To rs.ColumnCount - 1
Dim val As String = rs.GetString2(a)
row.Add(val)
Next
data.Add(row)
Loop
rs.Close
jq.RunMethod("dataTable", Array As Object(CreateMap("aaData": data, "bFilter": False, _
"bPaginate": True)))
'bind the selection changed event to the students table
ws.RunFunction("addSelectionToTable", Array As Object(tabella.Id, "TableView1_SelectedRowChanged"))
End Sub
Execution of the function:
FillTable(tabella, sql.ExecQuery("SELECT Cod, ListDesc, ListDescII FROM ANG_Prod"))
