Question

i’ve a Datatable that has a Column called sID with the values form 1 to 14 so i want to put each row with each sID in a new Datatable.

e.g Datatable1 contains all rows with sID=1
    Datatable2 contains all rows with sID=2
    Datatable3 contains all rows with sID=3

Now i am not sure how to use the Datatable.Select() to fill each Datatable with its rows.
Thanks

The Datatable.Select() method is to select row(s), to fill each Datatable you need to populate it like this:

Dim dt as DataTable
dt.Columns.Add("sID")
dt.Columns.Add("Column2")

Dim dr as Datarow
Dim i as integer

for i = 0 to 3
dr = dt.NewRow()
dr(0) = sID
dr(1) = "Column2Value"
dt.Rows.Add(dr)
next i

Or from a database like this:

Sub FillData()
    ' 1
    ' Open connection
    Using c As New SqlConnection(Properties.Settings.[Default].DataConnectionString)
        c.Open()
        ' 2
        ' Create new DataAdapter
        Using a As New SqlDataAdapter("SELECT * FROM EmployeeIDs", c)
            ' 3
            ' Use DataAdapter to fill DataTable
            Dim t As New DataTable()

                ' 4
                ' Render data onto the screen
                ' dataGridView1.DataSource = t; // <-- From your designer
            a.Fill(t)
        End Using
    End Using
End Sub
