Hi,

How do I clear the contents of CrystalReportViewer. I run a query which populates CrystalReportViewer correctly. If I run again without leaving the form, then the previous contents are still displayed. How do I clear then display?

A sample of my code is as follows.

Dim cryRpt As New ReportDocument
 
cryRpt.Load(Loads the crystal report form)
 
cryRpt.SetDataSource(MyDatasource.Tables(1))
Display the results on screen now
CrystalReportViewer1.ReportSource = cryRpt
CrystalReportViewer1.Zoom(75)
CrystalReportViewer1.Refresh()

Thanks for the quick response. Your code works to a point.
I build a new datasource everytime I want a new report. When I run the code, it is still holding onto the old data in the MyDatasource and displaying. I think I want to flush the data in the previous datasource before populating the reportviewer. I hope this makes sense?

Found the problem. See my comment.

I was not clearing my datasource everytime I ran a new report.
