Add a panel to your web form:
 <asp:Panel ID="Panel1" runat="server"></asp:Panel>

Add code to populate textboxes:

Dim cn As New SqlConnection("SERVER=.;DATABASE=usersDB;UID=sa;PWD=;")
    Dim cm As New SqlCommand("SELECT TOP 10 First_Name FROM members", cn)
    Dim da As New SqlDataAdapter(cm)
    Dim ds As New DataSet()
    da.Fill(ds)

    For Each dr As DataRow In ds.Tables(0).Rows
      Dim txt As New TextBox()
      txt.Text = dr("first_name").ToString()
      Panel1.Controls.Add(txt)
    Next

1.If you  are waitning just 8 results from your Query
2.If your Textboxes are already there and their names are TextBox1,TextBox2 e.t.c
then you can do this
Imports System.Data.SqlClient
Public Class Form1
    Private ProductList As New List(Of String)

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        
        Dim ProductConnection As New SqlConnection(YourProjectConnectionString)
        Dim ProductStr As String = "SELECT ProductName FROM Products"
        Dim ProductSql As New SqlCommand(ProductStr, ProductConnection)
        Dim ProductDa As New SqlDataAdapter(ProductSql)
        Dim ProductDs As New DataSet
        ProductDa.Fill(ProductDs)
        ProductList.Clear()
      
        For Each dr As DataRow In ProductDs.Tables(0).Rows
            ProductList.Add(dr.Item("ProductName").ToString)
        Next
  
       For i as Integer= 0 To ProductList.Count - 1
            Me.Controls.Find("TextBox" & i + 1, True)(0).Text = ProductList.Item(i)
        Next

    End Sub


End Class

Open in new window

If you dynamic populate the TxtBoxes using esolve's Solution just do not forget to adjust the Location of them to avoid overlap.
