hi,
i'm trying to build a GridColumncollection based on a .NET DataTable it does not compile because vs says:

"New cannot be used on a class that is declared mustinherit",

so i´m not able to run my code.
if i remove te new constructor i get an error saying Column is null, obviously because it does not have an instance declared....
how can i Fix this????

here is my code.


Dim DcArr As New EO.Web.GridColumnCollection

For i = 0 To dtVendedor.Rows.Count - 1
Dim Columna As New EO.Web.GridColumn
Columna.HeaderText = "2" 'dtVendedor.Rows(i).Item("Nombre")
Columna.DataType = GridColumnDataType.Auto
DcArr.Add(Columna)
Columna = Nothing
Next
