In this article I am going to explain how to show rotating ads
using Sql server database in asp.net without page refresh.
Description:
Adrotator control is used to show custom Ads (advertisements)
on asp.net build websites. When users click on any ad they will be redirect to link
assign for that. We can use both Xml and database as data source. Xml and database
table must have following properties and columns: ImageUrl, NavigateUrl, AlternateText,
Impressions, Keyword, Width and Height.
Implementations:
In this example I am going to use sql server database as
adrotator data source. I have create a table Ads and insert some dummy records into it.
Complete source of webform
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:Timer ID="Timer1" Interval="1000" runat="server"/>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:AdRotator ID="AdRotator1" runat="server" Target="_blank"/>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
</Triggers>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
Add namespaces
C# Code
using System.Configuration;
using System.Data.SqlClient;
using System.Data;
VB.net Code
Imports System.Data
Imports System.Data.SqlClient
Imports System.Configuration
Bind data to Adrotator
Create a method to get data from database and call it on page
load.
C# Code
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ToString());
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
AdRotator1.DataSource = BindAds();
AdRotator1.DataBind();
}
}
public DataTable BindAds()
{
SqlDataAdapter adp = new SqlDataAdapter("Select *
from Ads",
con);
DataTable dt = new DataTable();
adp.Fill(dt);
return dt;
}
protected void Timer1_Tick(object sender, EventArgs e)
{
AdRotator1.DataSource = BindAds();
AdRotator1.DataBind();
}
VB.net Code
Private con As New SqlConnection(ConfigurationManager.ConnectionStrings("connection").ToString())
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
If Not IsPostBack Then
AdRotator1.DataSource = BindAds()
AdRotator1.DataBind()
End If
End Sub
Public Function BindAds() As DataTable
Dim adp As New SqlDataAdapter("Select *
from Ads",
con)
Dim dt As New DataTable()
adp.Fill(dt)
Return dt
End Function
Protected Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
AdRotator1.DataSource = BindAds()
AdRotator1.DataBind()
End
Sub
