can't show a stimulsoft report more than 1 time

Question

I've created a simple report in vs.net 2008 with stimulsoft report 2013. I'm using these codes to show report:

    StiReport1.RegData(ds)
    StiReport1.Render()
    StiReport1.Show()

when I click on the button I Can see the report correctly for the first time. but when i close the reportviewer's Windows and click on that button again the report is empty (I can see the header or footer but no data loaded on the report) I think the report data not load again or something saved on cache. please Help. Thanks

Answer 1

The problem solved. I should just save the report and load it each time:

    Dim rpt As Stimulsoft.Report.StiReport = New Stimulsoft.Report.StiReport
    rpt.Load("report/MyReport.mrt")
    rpt.RegData(ds)
    rpt.Render()
    rpt.Show()

Answer 2

You need to reset your Viewer before rendering. Use ResetReport() function before Reg and Render codes.

SOLVED Try this code. its work for me

StiReport1.Dictionary.DataStore.Clear();

StiReport1.Dictionary.DataSources.Clear();
StiReport1.BusinessObjectsStore.Clear();

StiReport1.RegData(ds)
StiReport1.Dictionary.Synchronize();
StiReport1.Compile();
