Hello,
You can do the following:
1. Sort the data by cardcode before you load the matrix
or
2. Create a class for stroring the matrix row id and the customer code
When you search, you can define some Algoritm like binary search to find quickly in the sorted table or class
example for the class
    Class _BP
        Public row As Integer = 0
        Public cardcode As String = ""
    End Class
' Comparer class for soring
Public Class ComparerCardCodes
        Implements IComparer(Of _BP)
        Public Function Compare(ByVal x As _BP, ByVal y As _BP) As Integer Implements IComparer(Of _BP).Compare
            Return x.cardcode.CompareTo(y.cardcode)
        End Function
    End Class
'USe this clas when you load the matrix
Dim Bps As New List(Of _BP)()
' Loop when you load the matrix
                Dim bp As New _BP()
                bp.cardcode = CardCode
                bp.row = iRow
                Bps.Add(bp)
'After you have loaded,
                ' Sorting by CardCode
                Dim cpBp As New ComparerCardCodes()
                Bps.Sort(cpBp)
'Now when you find a cardcode, you can
                Dim bp2Find As New _BP()
                bp2Find.cardcode = CARDCODETOFIND
                Dim i As Integer = 0
'In a loop search
                i = Bps.BinarySearch(i, Bps.Count - 1, bp2Find, cp)
                if i = -1 then ' exit from the loop
'Result: for selection
                oMatrix.SelecRow(Bps.Item(i).row)
This is working independelty from the sort order of the filling.
Best Regards,
János
