as an example take a sample grid and populate with data from database and then press button
here text and id of button is word
protected void word_Click(object sender, EventArgs e)
{
//string attachment = "attachment; filename=f.xls";
SqlDataAdapter da = new SqlDataAdapter("select * from empdata", cn);
DataSet dsExport = new DataSet();
da.Fill(dsExport);
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw =
new System.Web.UI.HtmlTextWriter(tw);
//DataGrid dgGrid = new DataGrid();
//dgGrid.DataSource = dsExport;
DataGrid1.DataSource = dsExport;
// //Report Header
hw.WriteLine("" +
"Report for the Employee Information: " +
"");
//hw.WriteLine("
");
//// Response.AddHeader("emp info", attachment);
// // Get the HTML for the control.
//dgGrid.HeaderStyle.Font.Bold = true;
//dgGrid.DataBind();
//dgGrid.RenderControl(hw);
DataGrid1.HeaderStyle.Font.Bold = true;
DataGrid1.DataBind();
DataGrid1.RenderControl(hw);
// // Write the HTML back to the browser.
Response.ContentType = "application/msword";
this.EnableViewState = false;
Response.Write(tw.ToString());
Response.End();
}

Hey Varsha,
Use this code. This code has a ability to move the Selected Items from source to target. You can alter it as you like.
function AddItem(src,target){
for (i=src.length-1; i>=0; i--){
if (src[i].selected){
for (j=0; j < target.options.length; j++){
if (src.options[i].text.toUpperCase() < target.options[j].text.toUpperCase())
break;
}
var oOptions = document.createElement("option");
target.options.add(oOptions,j);
oOptions.value=src.options[i].value;
oOptions.innerHTML=src.options[i].innerHTML;
src.options.remove(i);
}
}
}

What you are asking here is really basic, you simply take the input value from the login form then execute a simple query against DB to select the value. There are tons of tutorials out there that you can learn, you might also download the starter kits from the Microsoft ASP.NET site to learn from them.

You get it like this:
LoginControl1.UserName.Trim();

I followed the article here http://www.kirupa.com/net/sql_asp_introduction.htm
everything compiles ok but when it get to opening the database I get error message
An attempt to attach an auto-named database for file C:\Path\Games.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share
I do not have any other databases with the same name and it is on the C drive so leads me to believe for some reason it can not open the database.
could someone please help me with this.
Thanks

ok i figured out what was wrong, .net 2.0 needed to be reinstalled, my app now runs but does not write to the database, is there something wrong with my code to write to the database?
SqlConnection connection;
protected void Page_Load(object sender, EventArgs e)
{
connection = new SqlConnection(ConfigurationManager.ConnectionStrings["GameConnection"].ConnectionString);
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
SqlCommand command = new SqlCommand("INSERT INTO gameTable(gameName, gamePlatform) VALUES (@id_gameName,@id_gmaePlatform)", connection);
SqlParameter nameContent = new SqlParameter("@id_gameName", SqlDbType.VarChar);
nameContent.Value = txtName.Text;
command.Parameters.Add(nameContent);
SqlParameter platformContent = new SqlParameter("@id_gamePlatform", SqlDbType.VarChar);
platformContent.Value = txtPlatform.Text;
command.Parameters.Add(platformContent);
connection.Open();
command.BeginExecuteNonQuery();
connection.Close();
Response.Redirect("Results.aspx");
}

Planker wrote: command.BeginExecuteNonQuery();
connection.Close();
You make an asynchronous call to insert data, but you close the connection right after that then how data can be inserted into DB. You might also double check the parameter name gmaePlatform as well.
