new in .Net but learning SqlConnection, SqlCommand and SqlDataReader How in code_behind

Hi.

I want to now a little about CodeBehind how to use it with SqlConnection, SqlCommand and SqlDataReader.

How i use:
Web.Config
<connectionStrings>
<add name="ConnectionStringTest" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\DSNbase.mdb;Persist Security Info=True"providerName="System.Data.OleDb"/>
</connectionStrings>

Default.aspx
<asp:RepeaterID="test"runat="server"DataSourceID="SqlDataSourcetest">
...
..
<asp:SqlDataSourceID="SqlDataSourcetest"runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionStringTest %>"
ProviderName="<%$ ConnectionStrings:ConnectionStringTest.ProviderName %>"
SelectCommand="SELECT [ID], [Name], [Sex], [Born], [Color], [Dog], [Images] FROM [Dogs] WHERE ([Dog] = 'YES') ORDER BY [ID]">
</asp:SqlDataSource>

How can i take my asp:SqlDataSource and put it in my CodeBehind, so it use the ConnectionString from my Web.Config and so i can use my Repeater on my default.aspx site.. !?
Maybe if u got a great link that show "How to do" maybe om MSDN/MSDN2.

You can use a datareader. Heres an example i put together using a stored procedure:

#region StoredProcedure GetDogs
// CREATE PROCEDURE GetDogs()
// AS
// SELECT ID, Name, Sex, Born, Color, Dog, Images FROM Dogs WHERE Dog='YES' ORDER BY ID
// RETURN
#endregion

//This will get the connectionstring from the web.config
SqlConnection objConn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionStringText"].ConnectionString);
SqlCommand objCmd = new SqlCommand("GetDogs", objConn);
objCmd.CommandType = CommandType.StoredProcedure;

objConn.Open();
SqlDataReader objRdr = objCmd.ExecuteReader(CommandBehavior.CloseConnection);

if (objRdr.HasRows)
{
testRepeater.DataSource = objRdr;
testRepeater.DataBind();
}
else { // do alternative if no data is present. }

objRdr.Close();
objConn.Close();

Hi.

How will this look like if im using VB.

This should work, but im not 100% sure, Im doing this by hand and not in VS, but its striaght forward and you should be able to see how to change it:

//This will get the connectionstring from the web.config
Dim objConn As SqlConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionStringText"].ConnectionString)
Dim objCmd As SqlCommand = new SqlCommand("GetDogs", objConn)
objCmd.CommandType = CommandType.StoredProcedure

objConn.Open();
Dim objRdr As SqlDataReader = objCmd.ExecuteReader(CommandBehavior.CloseConnection)

testRepeater.DataSource = objRdr
testRepeater.DataBind()

objRdr.Close()
objConn.Close()

Hope this helps.
