Filtering a datagridview based on a textbox input

[Pianoman23]

Using VS2017 I have created a windows form containing a datagridview populated from an Excel workbook.
The population is performed using the following code.

Imports System.IO
Imports ExcelDataReader
Public Class Products
    Dim FilePath As String
    Dim tables As DataTableCollection
    Dim result As New DataSet
    Dim dt As DataTable
    Private Sub Products_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Using ofd As OpenFileDialog = New OpenFileDialog()
            ofd.FileName = "E:\MWP\Databases\NoDupeLinkDB.xlsx"
            tbFile.Text = ofd.FileName
            Using stream = File.Open(ofd.FileName, FileMode.Open, FileAccess.Read)
                Using reader As IExcelDataReader = ExcelReaderFactory.CreateReader(stream)
                    result = reader.AsDataSet(New ExcelDataSetConfiguration() With {
                                                                   .ConfigureDataTable = Function(__) New ExcelDataTableConfiguration() With {
                                                                   .UseHeaderRow = True}})
                    tables = result.Tables
                    cboSheet.Items.Clear()
                    For Each table As DataTable In tables
                        cboSheet.Items.Add(table.TableName)
                    Next
                End Using
            End Using
        End Using
        cboSheet.Text = "Tabs"
        dt = tables(cboSheet.SelectedItem.ToString())

        dgvProdND.DataSource = dt

    End Sub

This works fine.
What I am looking to do is to type something into a textbox and have a second datagrid populated with matching records from the first.
So I would have dgvProdND populated as above; type something like "Abil" into the textbox and have a second datagrid (dgvResult) populated with rows from dgvProdND where the "Description" column matches, or is like the typed text.
Research on this appears to always refer to querying the source database (usually MS Access); but I don't have a connection to an Access database.
I'm fairly new to vb so please be gentle!!!
