hi

i use a dataset to set up the query and then pass the dataset to the crystal report viewer:

Dim newRpt As GeneralReport
        newRpt = New GeneralReport

        Make_con() 'sub that sets the connection to sql
        sqlCommand.Connection = sqlCon
        strQuery = "Select * From tableName"

        Dim sqlDA As SqlClient.SqlDataAdapter = New SqlClient.SqlDataAdapter(strQuery, sqlCon)

        strWhere = ""

        'SET UP THE QUERY HERE

        strQuery = strQuery & strWhere
        sqlDA.SelectCommand.CommandText = strQuery
        Dim sqlDS As New DataSet
        sqlDA.Fill(sqlDS)
        Me.cvReport.Visible = True
        newRpt.SetDataSource(sqlDS.Tables(0))
        cvReport.ReportSource = newRpt
        sqlCon.Close()

hope this helps u.

hi,

you ca create a crystal report in asp.net by

1. Create a new web form by right clicking your project and select add web form. name the form.

2. From a tool box drag and drop crystalreportviewer on to the form.
3. Add ur existing crystal report to your project by righting ur project and select add existing item choose ur report.

4. Drag and drop reportdocument from component in the tool box.
A pop window shows ur added report and all the exisiting report.
choose ur report and click ok. Add one textbox(txtbox) to hold your parameter.

5. Add the below.


        ' Binding by report object.
        'CRobj is a report object either u can pass the path or pass the class
        'testorganization_para() is the automatically generated class of report.

        Dim CRobj As New ReportDocument()
        Dim CRdiscretevalue As New CrystalDecisions.Shared.ParameterDiscreteValue()
        Dim CRParameterFieldDefinitions As ParameterFieldDefinitions
        Dim CRParameterFieldLocation As ParameterFieldDefinition
        Dim CRparametervalues As New CrystalDecisions.Shared.ParameterValues()

        ' Get report parameter's collection

        CRobj = New testorganization_para()
        faccrystalreport.ReportSource = CRobj ' faccrystalreport is a crystalreportviewer
        CRParameterFieldDefinitions = CRobj.DataDefinition.ParameterFields
        CRParameterFieldLocation = CRParameterFieldDefinitions.Item("organization city")
        CRparametervalues = CRParameterFieldLocation.CurrentValues

        Dim CRParameterDiscreteValue = New CrystalDecisions.Shared.ParameterDiscreteValue()
'txtbox is your textbox id from where you are passing ur parameter to the report.
        CRParameterDiscreteValue.Value = txtbox.text
        CRparametervalues.Add(CRParameterDiscreteValue)
        CRParameterFieldLocation.ApplyCurrentValues(CRpara metervalues)
        '
        ' Set the Crytal Report Viewer control's source to the report document.
        '

        faccrystalreport.ReportSource = CRobj

        'connection string and table information declaration

        Dim tablelongoninfo As New CrystalDecisions.Shared.TableLogOnInfo()
        Dim con As New CrystalDecisions.Shared.ConnectionInfo()

        Dim CRdatabase As Database
        Dim CRtable As Tables
        Dim cretable As Table

' Enter ur server name and databasename here
        con.ServerName = ""
        con.DatabaseName = ""
        con.UserID = "sa"
        con.Password = ""
        CRdatabase = CRobj.Database
        CRtable = CRdatabase.Tables

        For Each cretable In CRtable

            tablelongoninfo = cretable.LogOnInfo
            tablelongoninfo.ConnectionInfo = con
            cretable.ApplyLogOnInfo(tablelongoninfo)

        Next

        faccrystalreport.ReportSource = CRobj
'---------------------------------------------------------------------


this will work.

Please let me know about it.

thank you

Hi,
I am very new to asp.net and have a chance to look ur code for asp.net and crystal reports. Can you please tell me the following line in your code?

CRParameterFieldLocation = CRParameterFieldDefinitions.Item("organization city")
What is that "organization city"? Is it a database field?

Thanks! Your help will be appreciated.

Hi
I've been trying to create report but i found this problem

        Dim rpt As New CrystalReport()
   *** rpt.setDataSource(DA) ***
        CrystalReportViewer1.ReportSource = rpt
        conn.Close()

The report instance that i've create doesn't have method 'setDataSource', so error occurs when i run the application.

Please help,
Thanks in advance
