SQLConnection - probably simple

Hello all!

I'm fighting with this little problem. I'm trying to retrieve data from a
table in SQL Server 2k. I'm dead. The only result I get is retrieving the
headers of the columns - no data in it actually :/ I'm probably missing
something on the way. Could somebody explain me how do I get data and even
WHERE I should retrieve it to? Explain like to an idiot - really.

Don't know 'what' exactly you want to display, but below is a sample of how you can display
data from an SQL Table in a "DataGrid" using ASP.NET (written in C#).

<!-------------------------------BEGIN EXAMPLE------------------------------------------>
<%@ Page Language="C#" %>
<%@ import Namespace="Syst em.Data" %>
<%@ import Namespace="Syst em.Data.SqlClie nt" %>
<script runat="server">

void Page_Load(objec t sender, EventArgs e) {

if (!Page.IsPostBa ck) {

// Databind the data grid on the first request only
// (on postback, rebind only in paging and sorting commands)


void DataGrid_Page(o bject sender, DataGridPageCha ngedEventArgs e) {

DataGrid1.Curre ntPageIndex = e.NewPageIndex;

void DataGrid_Sort(o bject sender, DataGridSortCom mandEventArgs e) {

DataGrid1.Curre ntPageIndex = 0;
SortField = e.SortExpressio n;

// Helpers
// use a property to keep track of the sort field, and
// save it in viewstate between postbacks
protected String SortField {

get {
object o = ViewState["SortField"];
return (o == null) ? String.Empty : (String)o;
set {
ViewState["SortField"] = value;

void BindGrid() {

// TODO: update the ConnectionStrin g values for your application
string ConnectionStrin g =
"server=ServerN ame;database=Da tabaseName;UID= username;Passwo rd=password";
string CommandText;

// TODO: update the CommandText values for your application
if (SortField == String.Empty)
CommandText = "select Column1, Column2, Column3, Column4, Column5 from TableName
order by Column1";
CommandText = "select Column1, Column2, Column3, Column4, Column5 from TableName
order by " + SortField;

SqlConnection myConnection = new SqlConnection(C onnectionString );
SqlDataAdapter myCommand = new SqlDataAdapter( CommandText, myConnection);

DataSet ds = new DataSet();
myCommand.Fill( ds);

DataGrid1.DataS ource = ds;
DataGrid1.DataB ind();

<body style="FONT-FAMILY: arial">
<h2>Database example of ASP.NET DataGrid w/Paging & Sorting
<hr size="1" />
<form runat="server">
<asp:datagrid id="DataGrid1" runat="server" width="80%" CellSpacing="1" GridLines="None "
CellPadding="3" BackColor="Whit e" ForeColor="Blac k" OnPageIndexChan ged="DataGrid_P age"
PageSize="6" AllowPaging="tr ue" OnSortCommand=" DataGrid_Sort" AllowSorting="t rue">
<HeaderStyle font-bold="True" forecolor="whit e" backcolor="#4A3 C8C"></HeaderStyle>
<PagerStyle horizontalalign ="Right" backcolor="#C6C 3C6"
mode="NumericPa ges"></PagerStyle>
<ItemStyle backcolor="#DED FDE"></ItemStyle>

//--------------------------END EXAMPLE HERE------------------------------------------------>

NOTE: Copy the code into notepad, then save the file with a ".aspx" extension. The example is
VERY basic, but should give you a beginning point!

I have an SqlConnection object defined as a member of main form. I also have a thread that creates an SqlDataReader but uses the same SqlConnection object.

No exceptions are generated. Sometimes the...

In our new .NET web applications, we try to limit the use of SqlConnection to just one instance per page, even if there are multiple accesses to various queries.

However, this does requires more deliberate coding, like calling the...

Hello! Below is a simple program that works fine. In this program there is no explicit open for the SqlConnection instead the DataAdapter will open the Connection to the database automatically. Now to my question if I check the connection after the SqlDataAdapter has been created the connection is then closed ? So when does the SqlDataAdapter open and close the DataAdapter ?
