DataInitialize Event
See Also  Example


Raised after the ReportStart event to allow the addition of custom fields to the report's fields collection.

Syntax

Visual Basic (Declaration) 
Public Event DataInitialize() As EventHandler
Visual Basic (Usage)Copy Code
Dim instance As ActiveReport3
Dim handler As EventHandler
 
AddHandler instance.DataInitialize, handler
C# 
public event EventHandler DataInitialize()

Example

C#Copy Code
private void rptUnbound_DataInitialize(object sender, System.EventArgs eArgs)
{
   Fields.Add(
"CategoryName");
   Fields.Add(
"ProductName");    
   Fields.Add(
"UnitsInStock");        
   Fields.Add(
"Description");
}
Visual BasicCopy Code
Private Sub rptUnbound_DataInitialize(ByVal sender As Object, ByVal e As _
    System.EventArgs) Handles MyBase.DataInitialize
    Fields.Add("CategoryName")
    Fields.Add("ProductName")
    Fields.Add("UnitsInStock")
    Fields.Add("Description")
End Sub

Remarks

Custom fields can be added to a bound report (one that uses the built-in data source to retrieve records) or an unbound report (one that does not depend on the data source to get its records).

In a bound report, the report's data source is initialized, opened and its fields are added to the Fields collection before the DataInitialize event is raised.

The DataInitialize event is raised only once unless you call the Restart() method.

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