How to correctly filter a datatable (datatable.select)

Question

Dim dt As New DataTable
Dim da As New SqlDataAdapter(s, c)

        c.Open()
        If Not IsNothing(da) Then
            da.Fill(dt)
            dt.Select(\"Groupi         


        

Answer 1

dt.Select() returns an array of DataRows.

Why don't you use a DataView?

 DataView dv = new DataView(dt);
 dv.RowFilter = "GroupingID = 0";
 GridView1.DataSource = dv;
