Highlight a row in Datagridview based on textbox value

Good Evening.

I have a program in VB.Net that refreshes datagridview after you edit some data my problem here is im populating over 1000 records.

Let say Im editing row 999 and after i click update the data will refresh causing the datagridview to return at the top (The blue highlighter)

My goal here is how can I maintain it to its current position after update?

My solution here is highlight the data where Textbox1 = value

Is this possible like this?

'SAMPLE CODE
Datagridview1.Column(0).value.BlueHighLighter = Textbox1.text


Pls see my code on how i refresh DGV

Dim con11 As MySqlConnection = New MySqlConnection("server=192.168.2.87;userid=root;password=admin1950;database=inventory")
Dim sql1 As MySqlCommand = New MySqlCommand("select PONo,ItemCode,Description,QtyPack,PackUoM,QtyStan,StanUoM,UnitPrice,Total,Remarks,ExpiryDate from Receiving where RINo = '" & Add_Receiving_Items.TextBox1.Text & "';", con1)
Dim ds1 As DataSet = New DataSet
Dim adapter1 As MySqlDataAdapter = New MySqlDataAdapter
con1.Open()
adapter1.SelectCommand = sql1
adapter1.Fill(ds1, "MyTable")
Add_Receiving_Items.DataGridView1.DataSource = ds1.Tables(0)
con1.close()
With Add_Receiving_Items.DataGridView1()
.RowHeadersVisible = False
.Columns(0).HeaderCell.Value = "PO No"
.Columns(1).HeaderCell.Value = "Item Code"
.Columns(2).HeaderCell.Value = "Description"
.Columns(3).HeaderCell.Value = "Quantity/Pack"
.Columns(4).HeaderCell.Value = "Packaging UoM"
.Columns(5).HeaderCell.Value = "Quantity/Pc"
.Columns(6).HeaderCell.Value = "Standard UoM"
.Columns(7).HeaderCell.Value = "Unit Price"
.Columns(8).HeaderCell.Value = "Total"
.Columns(9).HeaderCell.Value = "Remarks"
.Columns(10).HeaderCell.Value = "Expiry Date"
End With

Add_Receiving_Items.DataGridView1.Columns.Item(0).Width = 80
Add_Receiving_Items.DataGridView1.Columns.Item(1).Width = 80
Add_Receiving_Items.DataGridView1.Columns.Item(2).Width = 120
Add_Receiving_Items.DataGridView1.Columns.Item(3).Width = 86
Add_Receiving_Items.DataGridView1.Columns.Item(4).Width = 68
Add_Receiving_Items.DataGridView1.Columns.Item(5).Width = 75
Add_Receiving_Items.DataGridView1.Columns.Item(6).Width = 68
Add_Receiving_Items.DataGridView1.Columns.Item(7).Width = 70
Add_Receiving_Items.DataGridView1.Columns.Item(8).Width = 80
Add_Receiving_Items.DataGridView1.Columns.Item(9).Width = 105
Add_Receiving_Items.DataGridView1.Columns.Item(10).Width = 63
Add_Receiving_Items.DataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomCenter
Add_Receiving_Items.DataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.BottomCenter
With Add_Receiving_Items.DataGridView1
.RowsDefaultCellStyle.BackColor = Color.WhiteSmoke
.AlternatingRowsDefaultCellStyle.BackColor = Color.Lavender
End With

Use DataGridView.CurrentRow property. But please be aware that CurrentRow is ReadOnly, you must use CurrentCell

Before refreshing your data store Dim oldIndex = DataGridView.CurrentRow.Index and after the refresh set DataGridView.CurrentCell = DataGridView.Rows(oldIndex).Cells(0)

EDIT:

My answer was downvoted without any comment. So I did a test and proved that the above code is working.

Create a form with a Button1 and a DataGridView1 with two columns and paste the following code:

Public Class Form1
    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        For i = 1 To 5
            DataGridView1.Rows.Add("foo" & i, "bar" & i)
        Next
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

        Dim currentIndex = DataGridView1.CurrentRow.Index
        currentIndex += 1
        If currentIndex >= DataGridView1.Rows.Count Then currentIndex = 0

        DataGridView1.CurrentCell = DataGridView1.Rows(currentIndex).Cells(0)
    End Sub
End Class
