Hi,

I have following code for DataList and the code behind in c# it is working fine.

I am trying to figure out how to refresh the page it every 10 seconds, i was thinking of placing timer but not sure which place it should go.

Any ideas how to do it? Thanks

ASP.NET

<asp:DataList ID="DataList1" runat="server" RepeatColumns="3" CellSpacing="3"
    RepeatDirection="Horizontal"  HorizontalAlign="Left"
    DataKeyField="email" DataSourceID="SqlDataSource1" Width="900px"
    onselectedindexchanged="DataList1_SelectedIndexChanged">
    <itemtemplate>

              Skipping the code here which is working fine
                </itemtemplate>

And in c#

C#

protected void Page_Load(object sender, EventArgs e)
{
  email.Text = "" + Session["email"];
}

protected void SqlDataSource1_Selecting(object sender, SqlDataSourceSelectingEventArgs e)
{

        if (!this.IsPostBack)
        {
            con.Close();
            con.Open();
            cmd = new SqlCommand("SELECT C, P FROM dr WHERE email='" + email.Text + "'", con);
           
            dr = cmd.ExecuteReader();
        
        }
}

Why go for any complex solution when the HTML can do it for you?

Use the HTML meta refresh tag on your page

HTML

<meta http-equiv="refresh" content="600">

One the page is loaded, it's on the client so that's where you need to make the refresh happen. There's a couple of ways you can do this.

1) Page directive
http://www.codelifter.com/main/tips/tip_011.shtml[^]

2) Using the setTimeout function

Both are a bit annoying in my opinion, I don't like whole page refreshes.

You could also look into anajax call to partially update the page, refreshing only the part of the page that's displaying the data.

JavaScript

<script type="text/javaScript">
    function timedRefresh(timeoutPeriod) {
	 setTimeout("window.location.reload(true);",timeoutPeriod);
    }
</script>

<body onload="timedRefresh(1000);">
</script>

OR

XML

<head runat="server">
    <title> Home page</title>
    <meta http-equiv="refresh" content="10" />
</head>

Here content=seconds
