FetchData Event

Raised every time a new record is processed.

[Visual Basic]
Public Event FetchData() As ActiveReport.FetchEventHandler
[C#]
public event ActiveReport.FetchEventHandler FetchData();

Event Data

The event handler receives an argument of type ActiveReport.FetchEventArgs containing data related to this event. The following ActiveReport.FetchEventArgs properties provide information specific to this event.

PropertyDescription
EOF This parameter is passed by reference and its default Value is True.  It has to be explicitly set to False for the report to continue processing more records when the report is unbound. For bound reports, the EOF property is set automatically.

Remarks

This event is used to set the values of custom unbound fields that were added in the DataInitialize event.

ActiveReports does not null unbound field values before firing this event.  The unbound field value is carried over so you should always set the values of all unbound fields in this event.

Note:  Do not reference the Fields collection outside the DataInitialize and FetchData events.

Example

[C#] 

private void rptUnbound_FetchData(object sender, DataDynamics.ActiveReports.ActiveReport. 
    FetchEventArgs eArgs) 

    try     
    {         
        m_reader.Read();         
        Fields["CategoryName"].Value = m_reader["CategoryName"].ToString();         
        Fields["ProductName"].Value = m_reader["ProductName"].ToString();         
        Fields["UnitsInStock"].Value = m_reader["UnitsInStock"].ToString();         
        Fields["Description"].Value = m_reader["Description"].ToString();         
        eArgs.EOF = false;     
    }     
    catch     
    {         
        eArgs.EOF = true;     
    } 
}

[Visual Basic] 

Private Sub rptUnbound_FetchData(ByVal sender As Object, ByVal eArgs As DataDynamics._
      ActiveReports.ActiveReport.FetchEventArgs) Handles MyBase.FetchData
      Try
          m_reader.Read()
          Me.Fields("CategoryName").Value = m_reader("CategoryName")
          Me.Fields("ProductName").Value = m_reader("ProductName")
          Me.Fields("UnitsInStock").Value = m_reader("UnitsInStock")
          Me.Fields("Description").Value = m_reader("Description")
          eArgs.EOF = False
          Catch ex As Exception
          eArgs.EOF = True
      End Try
End Sub
