Fetch data from the database and place it in a marquee

1. First we should take the marquee tag in the source of our web form(Page.aspx) page like this:->
<marquee direction=”up” onmouseover=”this.start()” onmouseout=”this.stop()”
scrolldelay=”300″ style=”height: 213px”>
<asp:Literal ID=”lt1″ runat=”server”></asp:Literal></marquee>
Note:-> literal to show the database values in the marquee
2.In Database:->
My Database Name:->db2
Create a table:->
create table news1
(
id int identity(1,1),
headings varchar(50)
);
3.Page.aspx coding:->
using System.Data.SqlClient;
SqlConnection conn1 = new SqlConnection(“data source=AB\\SQLEXPRESS;initial catalog=db2;integrated security=true”);
SqlDataAdapter da1 = new SqlDataAdapter(“select * from news1″, conn1);
DataSet ds1 = new DataSet();
da1.Fill(ds1, “news1″);
string s1;
s1 = “<table><tr><td><a href=Default3.aspx style=font-family: fantasy; font-size: small; font-weight:bold; font-style: normal; color: #660066>”;
s1 += ds1.Tables["news1"].Rows[0][1].ToString();
s1 += “</a></td>”;
s1 += “<br/>”;
s1 += “<tr><td><a href=Default2.aspx style=color: #9966FF; font-weight: bold;>”;
s1 += ds1.Tables["news1"].Rows[1][1].ToString();
s1 += “</a></td></table>”;
lt1.Text = s1.ToString();

CascadingDropDown in Ajax With ASP.net

Step1: Create a table in database:-

create table test
(
state1 varchar(50),
city varchar(50)
)

Step2:- In the .aspx Page:-

  <select id="statelist" runat="server" onchange="showCity()" style="width: 160px">
   <option></option>
   </select>
   <asp:DropDownList ID="citylist" runat="server" Width="184px">
   </asp:DropDownList>

Take statelist for State and citylist for City
When you select any item from statelist the citylist will automatically fill because of ajax

Step3:- Write this in the <head> Part:-
  <script language="JavaScript" type="text/javascript" >

var xmlHttp
var arr;
function showCity()
{

xmlHttp=GetXmlHttpObject()

var url="Default.aspx"
url=url+"?name="+document.getElementById('statelist').value

xmlHttp.onreadystatechange=stateChanged
xmlHttp.open("GET",url,true)
xmlHttp.send(null)
return false;
}

function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
   var str;
   str = xmlHttp.responseText;

   arr=str.split(",");
   var i;
   for(i=0;i<arr.length;i++)
   {
   dd2= document.getElementById("citylist")

   var theOption = new Option;
   theOption.text = arr[i];
   theOption.value = arr[i];
   dd2.options[i] = theOption;
   }
}
}

function GetXmlHttpObject()
{
var objXMLHttp=null
if (window.XMLHttpRequest)
{
objXMLHttp=new XMLHttpRequest()
}
else if (window.ActiveXObject)
{
objXMLHttp=new ActiveXObject("Microsoft.XMLHTTP")
}
return objXMLHttp
}

</script>

Step 4:- in the .cs page:-

SqlConnection con = new SqlConnection("data source = MY\\SQLEXPRESS; initial catalog = try; integrated security=true");
   protected void Page_Load(object sender, EventArgs e)
   {
   if (!Page.IsPostBack)
   {
   con.Open();
   SqlCommand cmd = new SqlCommand("select * from test", con);
   SqlDataReader dr;
   dr = cmd.ExecuteReader();

   statelist.DataSource = dr;
   statelist.DataTextField = "state";
   statelist.DataBind();
   dr.Close();
   con.Close();
   }

   if (Request.QueryString["name"] != null)
   {
   string name = Request.QueryString["name"];
   Response.Clear();
   con.Open();
   SqlCommand cmd = new SqlCommand("select * from test where state=@state", con);
   cmd.Parameters.AddWithValue("@state", name);
   SqlDataReader dr;
   dr = cmd.ExecuteReader();
   string str = "";
   int a = 0;
   while (dr.Read())
   {
   if (a == 0)
   str += dr["city"].ToString();
   else
   str += "," + dr["city"].ToString();

   a++;
   }
   Response.Write(str);

   Response.End();
   con.Close();

   }
   }
