How to show records in GridView between two dates - vb.net

Question

I have a search button and two textboxes that function as a datetime picker. What can I do to show all the records in a specific date interval? I am new to programming.
<%# Page Title="Report" Language="VB" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeFile="Report.aspx.vb"
Inherits="Report" %>
<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent">
<asp:GridView ID="gvItems" runat="server" AutoGenerateColumns ="false">
<Columns>
<asp:BoundField HeaderText="Part Number" DataField="Part_Number" readonly="true" ></asp:BoundField>
<asp:BoundField HeaderText="Last Inventory" DataField="Last_Inv" readonly="true" ></asp:BoundField>
<asp:BoundField HeaderText="Last Quantity" DataField="Last_Qty" readonly="true" ></asp:BoundField>
<asp:BoundField HeaderText="Inventory Today" DataField="Today_Inv" readonly="true" ></asp:BoundField>
<asp:BoundField HeaderText="Today's Quantity" DataField="Today_Qty" readonly="true" ></asp:BoundField>
</Columns>
</asp:GridView>
<br />
<br />
<div class ="container" >
<div class="input-group class col-sm-3 col-md-6">
<asp:Button ID="btnSearch" runat="server" Text="Search" />
<asp:TextBox ID="txtbxSearch1" runat="server" TextMode ="Date" Width="205px"></asp:TextBox>
<asp:TextBox ID="txtbxSearch2" runat="server" TextMode ="Date" Width="205px"></asp:TextBox>
</div> <br /> <br />

Imports System.Data
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
Dim ds As DataSet = New DataSet
ds.Tables.Add(New DataTable)
ds.Tables(0).Columns.AddRange(New DataColumn() {New DataColumn("Id", GetType(System.Int32)), New DataColumn("Name", GetType(System.String)), New DataColumn("DOB", GetType(DateTime))})
ds.Tables(0).Rows.Add(1, "John Hammond", "12/12/1996")
ds.Tables(0).Rows.Add(2, "Mudassar Khan", "11/16/1995")
ds.Tables(0).Rows.Add(3, "Suzanne Mathews", "10/20/1997")
ds.Tables(0).Rows.Add(4, "Robert Schidner", "09/22/1991")
Dim dt2 As DataTable = New DataTable
dt2 = ds.Tables(0).Select.Where(() => { }, ((Convert.ToDateTime(p("DOB")) >= Convert.ToDateTime("12/12/1996")) _
AndAlso (Convert.ToDateTime(p("DOB")) >= Convert.ToDateTime("12/12/1996")))).CopyToDataTable
GridView1.DataSource = dt2
GridView1.DataBind
