Session Management

Session is a important object to store serializable information that must be accesible in all pages in the web application.
It has some important points which are as;

It is tracked by the 120 bit indentifier
Session is tracked with the session ID in two ways
1. By cookies (session is stored in special cookie ASP.NET_SessionId)
2. By modified url
The session default time-out in 20 mintues
Session in controlled in four modes
1. InProc default mode
2. StateServer: Here a separate window service handles it known as "ASP.NET State Service".
3. SQLServer:It is best mode for storage, it is persite event in case of failures.
  To make this enable we use a tool called "aspnet_regsql.exe".The default database for storage of session is ASPState
4. Custom

Using Repeator to show data in Xml files

1. Firstly make xml file "data.xml"
<?xml version="1.0" encoding="utf-8" ?>
<catalog>
<cd>
    <Name>Veer</Name>
    <Id>10</Id>
</cd>
<cd>
    <Name>Karan</Name>
    <Id>11</Id>
</cd>
</catalog>

2. Add the repeator control as

form id="form1" runat="server">

        <asp:Repeater ID="cdcatalog" runat="server">
        <HeaderTemplate>
        <table border="2px" width="100%">
        <tr>
        <th>Name</th>
        <th>ID</th>
        </tr>
        </HeaderTemplate>
        <ItemTemplate>
        <tr>
        <td><%#DataBinder.Eval(Container.DataItem,"Name") %></td>
        <td><%#DataBinder.Eval(Container.DataItem,"Id") %></td>
        </tr>
        </ItemTemplate>

        <FooterTemplate>
        </table>
        </FooterTemplate>
        </asp:Repeater>
    </form>

3. Now in page_load event read xml file by dataset and add that dataset as reference to the repeator control

protected void Page_Load(object sender, EventArgs e)
    {
        DataSet ds = new DataSet();
        ds.ReadXml(MapPath("data.xml"));
// cdcatalog in ID of the repeator control
        cdcatalog.DataSource=ds;
        cdcatalog.DataBind();
    }
