我正在尝试遵循本教程http://www.daypilot.org/calendar-tutorial.html。我想创建一个使用数据库中数据的日历。我已经创建了一个与教程相同的名为 event 和 data 的表。表名叫做event，里面有id、name、eventstart、eventend、resource 5个字段。
但我正在为我的数据库使用 .mdf。本教程使用 sqlite 作为数据库。而且我的代码有错误，因为我没有使用 sqlite 数据库。我想为我的数据库使用 .mdf，如何更改我的代码？
public partial class number2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
lblVenue.Text = Session["roomvalue"] != null ? Session["roomvalue"].ToString() : "";
if (!IsPostBack)
{
DayPilotCalendar1.StartDate = DayPilot.Utils.Week.FirstDayOfWeek(new DateTime(2009, 1, 1));
DayPilotCalendar1.DataSource = dbGetEvents(DayPilotCalendar1.StartDate, DayPilotCalendar1.Days);
DataBind();
}
}
protected void DayPilotCalendar1_EventMove(object sender, DayPilot.Web.Ui.Events.EventMoveEventArgs e)
{
dbUpdateEvent(e.Value, e.NewStart, e.NewEnd);
DayPilotCalendar1.DataSource = dbGetEvents(DayPilotCalendar1.StartDate, DayPilotCalendar1.Days);
DayPilotCalendar1.DataBind();
DayPilotCalendar1.Update();
}
private DataTable dbGetEvents(DateTime start, int days)
{
SQLiteDataAdapter da = new SQLiteDataAdapter("SELECT [id], [name], [eventstart], [eventend] FROM [event] WHERE NOT (([eventend] <= @start) OR ([eventstart] >= @end))", ConfigurationManager.ConnectionStrings["projectConnectionString"].ConnectionString);
da.SelectCommand.Parameters.AddWithValue("start", start);
da.SelectCommand.Parameters.AddWithValue("end", start.AddDays(days));
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
private void dbUpdateEvent(string id, DateTime start, DateTime end)
{
using (SQLiteConnection con = new SQLiteConnection(ConfigurationManager.ConnectionStrings["db"].ConnectionString))
{
con.Open();
SQLiteCommand cmd = new SQLiteCommand("UPDATE [event] SET [eventstart] = @start, [eventend] = @end WHERE [id] = @id", con);
cmd.Parameters.AddWithValue("id", id);
cmd.Parameters.AddWithValue("start", start);
cmd.Parameters.AddWithValue("end", end);
cmd.ExecuteNonQuery();
}
}
}
