How to Create a Gridview with Scroll bar using ASP.NET 2.0 and VB is actually very simple. First, you will need to import the System.Data.SqlClient namespace for binding data to GridView. Then enclose your Gridview in a <div> tag and set the overflow style to auto/scroll.

We use the Page_Load event to bind the data. Then we can dynamically add style to GridView for layout.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
If (Not IsPostBack) Then
Dim connectionString As String = "server=localhost;database=Northwind;Integrated Security=SSPI" Dim customers As String = "SELECT ContactName,CompanyName,Address FROM Customers" Using con As New SqlConnection(connectionString)
Dim ds As New DataSet()
Dim da As New SqlDataAdapter(customers, con)
da.Fill(ds, "Customers")
GridView1.Attributes.Add("style", "table-layout:fixed")
GridView1.AutoGenerateColumns = True
GridView1.DataSource = ds
GridView1.DataBind() End Using End If |
The front end .aspx page looks something like this: DIV with "style="overflow-y: scroll; height: 200px" in aspx page will create a scrollbar.
<script type="text/javascript">
function s()
{
var t = document.getElementById("<%=GridView1.ClientID%>");
var t2 = t.cloneNode(true)
for(i = t2.rows.length -1;i > 0;i--)
t2.deleteRow(i)
t.deleteRow(0)
a.appendChild(t2) }
window.onload = s
</script>
<table width="600" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#cccccc">
<tr> <td bgcolor="#eeeeee" class="header1"> <fieldset> <legend>GridviewWithScrollbar</legend> <div id="a"> </div> <div style="overflow-y: scroll; height: 200px"> <asp:GridView ID="GridView1" runat="server" Font-Size="12px" BackColor="#FFFFFF" GridLines="Both" CellPadding="4" Width="560"> <HeaderStyle BackColor="#EDEDED" Height="26px" /> </asp:GridView> </div> </fieldset> </td> </tr> |
The flow for the code behind page is as follows.
Imports System
Imports System.Data
Imports System.Configuration
Imports System.Collections
Imports System.Web
Imports System.Web.Security
Imports System.Web.UI
Imports System.Web.UI.WebControls
