Example

In This Topic
    DataInitialize Event
    In This Topic
    Raised after the ReportStart event to allow the addition of custom fields to the report's fields collection.
    Syntax
    'Declaration
     
    Public Event DataInitialize As EventHandler
    public event EventHandler DataInitialize
    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.

    Example
    private void rptUnbound_DataInitialize(object sender, System.EventArgs eArgs)
    {
        Fields.Add("CategoryName");
        Fields.Add("ProductName");    
        Fields.Add("UnitsInStock");        
        Fields.Add("Description");
    }
    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
