	I have created a application, in which I provide some options to user. These options are used to build the query. User select these options and when press "Create Report" button, my application create a query according to user selected options and generate the report. Now when user select another options and press "Create Report" button, previous report get replace with new report. That mean at a time only one report can be generated. So my requirement is, instead of replacing previous report with new report, it should be fresh new report. Is it possible to generate more than 1 report with different result? Any help will be appreciated. Thanks, Edited by btough - 18 Jun 2009 at 5:06am

	absolutely. When you 'create' the report in the app, do something like dim cr as new frmViewer, yes, I program in VB...for c# it would be what...frmVeiwer cr = New frmViewer (); this will create a new instance of the control and will allow multiple reports to be displayed. We only wanted 1 copy, so I search for the mdichildren collection to prevent duplication. HTH

	Thank you lockwelle, My crystal report viewer name is crystalReportViewer2. I use - crystalReportViewer2.ReportSource = rptDoc; And it displays the report. As per your suggestion, if I use - CrystalDecisions.Windows.Forms.CrystalReportViewer viewer = new CrystalDecisions.Windows.Forms.CrystalReportViewer(); viewer.ReportSource = rptDoc; it display blank report. Any suggestion will be appreciated. Thanks, Edited by btough - 18 Jun 2009 at 4:46am

	Dim cr As CrystalDecisions.CrystalReports.Engine.ReportDocument Dim vwr As New frmReport Try cr = crReport 'set the dataset cr.SetDataSource(dsReport) 'set the report to display vwr.crvReport.ReportSource = cr vwr.Text = Me.Text vwr.Name = Me.Text vwr.MdiParent = Me.ParentForm vwr.Show() Catch ex As Exception End Try Here is my code. I am pretty sure that this will create multiple reports as I have removed the code that checks for prior existance. In the past our app had multiple reports (every time you ran the report, you got a new viewer, but someone decided that, that was a bad thing). Should be simple enough to translate to C#. HTH

	I have a form that has the Crystal report viewer on it so that I can set the report as a MDI child form, that is all that frmReport is. HTH

	Thank you lockwelle for help. My CrystalReport Viewer control is on Form2. So every time when user press "Create Report" button from Form1, I created new instance of Form2 i.e. Form2 frm2 = new Form2();. This solved my problem. Thanks.
