protected void Page_Load(object sender, EventArgs e)
{
string abc = "hello world";
Response.Write("<marquee>"+abc+"</marquee>");
}
Now connect your abc string to the database's datareader object and execute. i.e..
sqldatareader dr = commandobject.executereader();
while (dr.read())
{
abc = dr[0].Tostring();
}
So it'll display what exactly is the data, as a marquee tag.
