Question
What do i try to achieve:
Trying to get the following result roughly
[day number] [FixtureTeamHome] v [FixtureTeamAway]
[month name] [Shortdescription], [Venue]
On the Page_load I retrieve the Team Details page which has all the fixtures involved First of all is this the correct way, secondly i got the result needed but how would i add a style this as currently s += "
thank you for your advice, help and directions
public partial class WebForm6 : System.Web.UI.Page { public string TeamTitle = null; public string TeamTitle1 = null; protected void Page_Load(object sender, EventArgs e) { DataView TeamRecordSet = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty); foreach (DataRowView DRV in TeamRecordSet) { lblTeamName.Text = DRV["TeamName"].ToString(); lblTeamNameShortInfo.Text = DRV["TeamShortInfo"].ToString(); Image1.ImageUrl = "~/style/images/teams/" + DRV["TeamPhoto"].ToString(); } DataView TeamFixtureRecordSet = (DataView)SqlDataSource2.Select(DataSourceSelectArguments.Empty); string s = "<ul class=\\"latest-posts\\" id=\\"TeamFIxtures\\">"; foreach (DataRowView DRV1 in TeamFixtureRecordSet) { int FixtureMonth = (int)DRV1["FixtureMonth"]; string strMonthName = CultureInfo.CurrentCulture.DateTimeFormat.GetAbbreviatedMonthName(FixtureMonth); s += "<li><span class=\\"date\\"><em class=\\"day\\">"; s += "</em><em class=\\"month\\">" + strMonthName + "</em></span>"; // Fixture ================================================================ // Home Team int FixtureTeamHomeID = (int)DRV1["FixtureTeamHomeID"]; TeamNameHome(FixtureTeamHomeID); s += "<a href=\\"#\\">" + TeamTitle + "</a>"; TeamTitle = null; s += " v "; // Away Team int FixtureTeamAwayID = (int)DRV1["FixtureTeamAwayID"]; TeamNameAway(FixtureTeamAwayID); s += "<a href=\\"#\\">" + TeamTitle1 + "</a><br />"; TeamTitle1 = null; // Venue s += "<a href=\\"#\\">" + DRV1["FixtureShortInfo"].ToString() + "</a><br /><br />"; s += "<a href=\\"#\\">" + DRV1["VenueID"].ToString() + "</a></li>"; } s += "</ul>"; lblTeamFIxtures.Text = s; } public void TeamNameHome(int arg1) { using (SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["WCDB_local"].ConnectionString)) { string sqlSelect = @"select TeamName from Teams where TeamID = @TeamID"; using (SqlCommand cmd = new SqlCommand(sqlSelect, conn)) { cmd.Parameters.AddWithValue("@TeamID", arg1); conn.Open(); TeamTitle = cmd.ExecuteScalar().ToString(); } } } public void TeamNameAway(int arg2) { Int32 myTeamID = arg2; using (SqlConnection conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["WCDB_local"].ConnectionString)) { string sqlSelect = @"select TeamName from Teams where TeamID = @TeamID"; using (SqlCommand cmd = new SqlCommand(sqlSelect, conn)) { cmd.Parameters.AddWithValue("@TeamID", arg2); conn.Open(); TeamTitle1 = cmd.ExecuteScalar().ToString(); } } } I think i might have sussed it, and slowly beginning to understand the logic behind it , could i have an opinion if this is the correct way to approach this ? thanks again guys, every little advice helps....

Basically, you're using ASP classic techniques with some other not so pretty code.
No flame, but this makes the application hard to debug :) So this is not an answer to your question but a lookup tip
IMO a good place to start would be researching data binding / 'Live binding', which is basically creating the (design) skeleton in ASPNET and then binding a datasource to it. Easy to implement and maintain
