To allow passing a procedure parameter to an XtraReport descendant class (XtraReport1), it's updated with an argument which is used while populating the DataSet instance.
On the web page, a DropDownList control is placed, which is populated with the list of parameters.
In the example, the "CustOrdersOrders" stored procedure (Northwind database) with the "CustomerID" parameter is used, so the DropDownList contains every CustomerID from the Customers table.
Within the Page_Load event handler, the ReportViewer.Report property is updated using a newly created report instance.

Is there any "How To" for this? It seems to contradict other examples which use _BeforePrint
Is part of this example missing?
Added By: Mark D Loaney at: 6/20/2012 3:59:08 AMI've been wasting days trying to get this working, it appears that when I pass the parameters in the system breaks. I have a procedure that has the following parameters:
@OrganisationID INT = 0,
@Key INT = 3,
@WeekStarting DATE = NULL,
@WeekEnding DATE = NULL,
@DivisionID INT = 0,
@WorkgroupID INT = 0,
@EmployeeID INT = 281,
@Factor FLOAT = 0.00000
of which I only really need Key, EmployeeID, Division and Workgroup
The 'New' in xtrareports is as follows (note if I comment out the parameters passed in it works with the detault values and returns data:
Public Sub New(ByVal mEmployeeID As Integer, ByVal mKey As Integer, ByVal Org As Integer, divsn As Integer, wrkgp As Integer)
MyBase.New()
'This call is required by the Designer.
InitializeComponent()
cpM_Reports_StaffTableAdapter1.Fill(Me.staff1.CPM_Reports_Staff, Convert.ToInt32(Org), Convert.ToInt32(mKey), Convert.ToDateTime(Now()), Convert.ToDateTime(Now()), Convert.ToInt32(divsn), Convert.ToInt32(wrkgp), Convert.ToInt32(mEmployeeID))
End Sub
ie this works, but of course the parameters aren't there!
Public Sub New() 'ByVal mEmployeeID As Integer, ByVal mKey As Integer, ByVal Org As Integer, divsn As Integer, wrkgp As Integer)
MyBase.New()
'This call is required by the Designer.
InitializeComponent()
'cpM_Reports_StaffTableAdapter1.Fill(Me.staff1.CPM_Reports_Staff, Convert.ToInt32(Org), Convert.ToInt32(mKey), Convert.ToDateTime(Now()), Convert.ToDateTime(Now()), Convert.ToInt32(divsn), Convert.ToInt32(wrkgp), Convert.ToInt32(mEmployeeID))
End Sub
The proper values are coming in to the system when I put in a breakpoint - seems that the initialise isn't firing??
The code on the webform is
Dim Division As Integer = 0
Dim Workgroup As Integer = 0
Dim Key As Integer = lstFilter.SelectedIndex
If IsNumeric(lstDivision.SelectedValue) Then Division = CInt(lstDivision.SelectedValue)
If IsNumeric(lstWorkgroup.SelectedValue) Then Workgroup = lstWorkgroup.SelectedValue
Dim report As New XStaffActivity(Helpers.EmployeeID, Key, Helpers.MyCompanyID, Division, Workgroup)
rvStaffActivity.Report = report
Help please (PS I've copied the full xtrareports code below (cutting out the 60 off labels etc on there):
