Sometimes, when I open report with WebViewerFx, I have issue like that:
Server cannot set status after HTTP headers have been sent.

at System.Web.HttpResponse.set_StatusCode(Int32 value)
at Stimulsoft.Report.WebFx.StiWebViewerFx.ResponseBuffer(Byte[] buffer, String contentType, Int32 cacheTimeout)

Hello,

Please try to set the following option:

Code: Select all

StiOptions.Web.ClearResponseHeaders = false

Also, in your code, comment out the following line:

Code: Select all

report.Render(False)
report.Dictionary.Variables("PF_DateActive").RequestFromUser = False
'StiWebViewerFx1.Report = report  - this line is not needed
StiWebViewerFx1.View(report)

Thank you.

Hi,
Thanks for reply, I still see this issue, please help.

Code: Select all

        StiOptions.Web.ClearResponseHeaders = False
        report.Load(sPathReport & "Report_Mau_G1.mrt")
        report.RegData(objReport.Load_Report_G1(Active_ID, Hospital_ID, sFrom_Date, sTo_Date, Accept_YN))
        report.Compile()

        report.Render(False)
        report.Dictionary.Variables("PF_DateActive").RequestFromUser = False
        StiWebViewerFx1.View(report)

Hello,

We were unable to reproduce the error using the information you supply. Please send fully working project for the analysis and testing. Perhaps the error depends on something else.

Thank you.

Hi,
When I set following option

Code: Select all

        'StiOptions.Web.ClearResponseHeaders = True
        StiOptions.Web.AllowUseResponseFlush = False
        'Response.BufferOutput = False
        HttpContext.Current.Response.ClearHeaders()

It run very good.

Hello,

On some servers (especially with MediumTrust) can be is prohibited Flush command in sending data. We are glad that you find a workaround.

Let us know if you need any additional help.
Thank you.
