    Hello Sai Krishna,

    We can not answer all of your questions here. You can google it for sample application of authentication & authorization.

    2--> Themes

    // Get the theme name from a QueryString variable
    string ThemeName;
    ThemeName = Request.QueryString["thename"];
    if (ThemeName != null)
    Page.Theme = ThemeName;

    4--> XML

    <html xmlns="" >
    <head runat="server">
    <form id="form1" runat="server">
    <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine" Width="1000px" Height="500px"></asp:TextBox>

    Code - behind :

    using System.Data;
    using System.Data.SqlClient;
    using System.Xml;

    SqlConnection con = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|Database1.mdf;Integrated Security=True;User Instance=True");
    protected void Page_Load(object sender, EventArgs e)

    SqlCommand cmd = new SqlCommand("SELECT * FROM Employees", con);
    SqlDataReader dr = cmd.ExecuteReader();
    string strXML = "<EMPLOYEES>" + Environment.NewLine + Environment.NewLine;
    while (dr.Read())
    strXML += "<EMPLOYEE>" + Environment.NewLine +
    "<ID>" + dr[0].ToString() + "</ID>" + Environment.NewLine +
    "<NAME>" + dr[1].ToString() + "</NAME>" + Environment.NewLine +
    "<DESIGNATION>" + dr[2].ToString() + "</DESIGNATION>" + Environment.NewLine +
    "<EMAIL>" + dr[3].ToString() + "</EMAIL>" + Environment.NewLine +
    "</EMPLOYEE>" + Environment.NewLine + Environment.NewLine;
    strXML += "</EMPLOYEES>";

    XmlDocument xDoc = new XmlDocument();

    TextBox1.Text = strXML;
    catch(Exception ex)

    See the attached image. It's an output i have got using above mentioned code.

    Hope this will help you.

    Hello Sai Krishna,

    Theme doesn't mean css file. Theme is too much different from css file in ASP.NET

    Themes in ASP.NET :
    You should create .skin file in ASP.NET to apply it on controls.

    Default skin template. The following skins are provided as examples only.

    1. Named control skin. The SkinId should be uniquely defined because
    duplicate SkinId's per control type are not allowed in the same theme.

    <asp:GridView runat="server" SkinId="gridviewSkin" BackColor="White" >
    <AlternatingRowStyle BackColor="Blue" />

    2. Default skin. The SkinId is not defined. Only one default
    control skin per control type is allowed in the same theme.

    <asp:Image runat="server" ImageUrl="~/images/image1.jpg" />
    <asp:Label runat="server" Backcolor="#ff9999"/>
    <asp:Button runat="server" Forecolor="Blue"/>
    <asp:TextBox runat="server" Font-Size="small" Backcolor="#66ccff"/>

    <asp:TextBox runat="server" Font-Size="large" Backcolor="#ff9966" SkinID="t"/>

    If you are defining SkinID="t" than wherever you will use SkinID in textbox only on those textboxes it will be applied. Where in other control it will applied on all controls if you are adding theme in your page.

    Hope it will help you.

    Hi Saikrishna.

    Authentication modes in are Windows, forms and passport.
    Authentication is like checking whether he is allowed user or not.
    Authorization is like checking whether the user has rights to access particular resource.
    < authentication mode="Windows"/>
    <location path="Admin.aspx">
    <allow roles="Administrator"/>
    <deny users="*"/>
    </ authorization >
