Range Parameters?

I am currently working with a report that displays four columns and the report source is a store procedure that takes two parameters or arguments from the user in order to display the data. This is going to be developed in visual studio 2005m language: visual.

My question is, How can I pass parameters from one webform to another webform and display the data in the second one? Obviously the second webform has the crystal report viewer but I dont know how to send this two parameters which are date range to display the data that the user wants.

Well, when you submit the first webform, read the values from the input boxes and put them the into session variables. Then when you show your second form, read the values from the session variables, and pass them as parameters in your Crystal Reports.

The Crystal Report has to read the data from a Procedure (that's the way I know at least), and when you pass the values as parameters, Crystal Report will pass the same values to the Procedure.

How Can I do this?????

Well, I know it's not possible to make a procedure in Access database, so if you are using Access as your database, then I don't know how to do this... (then wait for someone else who knows more about this to reply to your question)

But... if you are using SQL Server (the only one I know...), You can make a procedure like this:

Code:

---

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE proc_ListRecords
        @FromDate datetime,
        @ToDate datetime
AS
BEGIN
        SET NOCOUNT ON;

        SELECT * FROM SOME_TABLE WHERE SOME_TABLE.FromDate BETWEEN @FromDate AND @ToDate
END
GO

---

Then in your Crystal Reports, you have to select the procedure "proc_ListRecords" to read the data from, and Crystal Reports will add the FromDate, and ToDate parameters automatically.

After that, in code, you have to pass the values to the Crystal Report when you run it, something like this:
Please note that this is VB6 code, I'm not sure how you do this in .NET, but it should be simmilar...

Code:

---

    Dim CRApp As New CRAXDDRT.Application
    Dim PrintReport As CRAXDDRT.Report
    Dim ReportFileName As String

        ReportFileName = App.Path & "\Reports\CR_Report.rpt"
        Set PrintReport = CRApp.OpenReport(ReportFileName)
       
        PrintReport.Database.Tables(1).ConnectionProperties.Item("user id") = ConnUserName
        PrintReport.Database.Tables(1).ConnectionProperties.Item("password") = ConnPassword

        PrintReport.ParameterFields.GetItemByName("@FromDate").AddCurrentValue FromDate
        PrintReport.ParameterFields.GetItemByName("@ToDate").AddCurrentValue ToDate

        PrintReport.SelectPrinter "", "printer name here, or comment line to select default printer", ""
        PrintReport.PrintOut False
       
        Do While PrintReport.PrintingStatus.Progress = crPrintingInProgress
            DoEvents
        Loop

Sorry if I could not be of more help (I don't know .NET very well), I did some webforms in the past, but did not need to do any Crystal Reports in it. I only did Crystal Reports in VB6...

:bigyello: Muchas Gracias!!! = Thank You!!!

I will try to change it to vb.net and see if it works :thumb:
