Return specified days from database

Asked by Anonymous

Hi,

I am using daypilot lite 2.3. I managed to connect the daypilot to my database but all events are rendering on one single day, todays current date. How can I render the events based their own specified days?

Possibly you didn't retrieve or not bind the date for each even. How does your query and binding look like? Or course you must also set the Calenders properties correctly, something like StartDate and DaysDisplayed or similar..

Greetings,

Martin

Martin is right, it seems that you are binding to a time-only field. The column values specified by DataStartField and DataEndField properties are converted to DateTime using Convert.ToDateTime() method. If you supply just time, current date will be added during the conversion.

here is how my binding and query looks like...also my DataStartField and DataEndField are bound to data with the date and time are supplied.

protected DataTable GetEventData()
{
SqlConnection myConnection = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["ConnectionString"]);
myConnection.Open();

SqlTransaction myTrans = myConnection.BeginTransaction();

SqlCommand myCommand = new SqlCommand();
myCommand.Connection = myConnection;
myCommand.Transaction = myTrans;
myCommand.CommandText = "Select * From appointment";
myCommand.ExecuteNonQuery();
myTrans.Commit();
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(myCommand);
da.Fill(ds);
myConnection.Close();

Session["EventData"] = ds.Tables[0];

return (DataTable)Session["EventData"];

}

Hi.

1. First, the lines that are commented out are not necessary (SqlDataAdapter.Fill() can open and closes the connection and transaction for you).
It's also not recommended to store the result in Session unless there is a specific reason for that. You can store it in a private field that will be used during a single page load. After page reload (or in another page) you will want to reload the data from the database anyway.
In the examples, Session is used just to emulate the database (to keep the changes during the session duration).

SqlConnection myConnection = new SqlConnection(System.Configuration.ConfigurationManager.AppSettings["ConnectionString"]);
//myConnection.Open();
//SqlTransaction myTrans = myConnection.BeginTransaction();
SqlCommand myCommand = new SqlCommand();
myCommand.Connection = myConnection;
//myCommand.Transaction = myTrans;
myCommand.CommandText = "Select * From appointment";
//myCommand.ExecuteNonQuery();
//myTrans.Commit();
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(myCommand);
da.Fill(ds);
//myConnection.Close();

Session["EventData"] = ds.Tables[0];

return (DataTable)Session["EventData"];

2. Can you please post your "appointment" table DDL definition and DayPilot declaration from .aspx file?

"Appointment Table"

Appt_day application_type appt_IDendDate
Jul 3 2007 9:30AM employment 1Jul 3 2007 9:45AM

<DayPilot:DayPilotCalendar id=DayPilotCalendar1 runat="server" Width="500"
NonBusinessHours="HideIfPossible" TimeFormat="Clock12Hours"
PkColumnName="appt_ID" NameColumnName="last_name"
EndColumnName="endDate" BeginColumnName="appt_time"
HourHeight="80" BusinessEndsHour="12" >

if (!IsPostBack) { DayPilotCalendar1.DataSource = GetEventData();}

You are using BeginColumnName="appt_time" but according to the table sample above it seems it should be BeginColumnName="Appt_day". Would changing it fix the problem?

No, that does not change anything
