Creating reports and dashboards | Stimulsoft community forum

Sorry for the delay, but I was on vacation.

I downloaded the latest version...and I am now getting an error message.

The following error was caused when I tried create a new report with the following code.

Stimulsoft.Report.StiReport stiReport = new Stimulsoft.Report.StiReport();


DataSet ds = PrestoReportsManager.Instance.GetSQLViewStructure(SQLViewName);

stiReport .RegData(ds); // The dataset is valid.
stiReport .Dictionary.ImportXMLSchema(ds);



Stimulsoft.Report.Web.StiWebDesignerOptions.ModifyDictionary = true;
Stimulsoft.Report.Web.StiWebDesignerOptions.ModifyConnections = true;
Stimulsoft.Report.Web.StiWebDesignerOptions.ModifyVariables = true;

stiReport .Dictionary.Synchronize();
WebReportDesigner.Design(stiReport );

One more thing.

The very next time I tried to do the EXACT SAME THING....It worked fine.

Hello, Mike

Most likely there is some problem with temporary report storage in the server cache. We have added a new property UseCache and a new event OnGetReport for WebDesigner. Use this event to load the report.

The patch will be available in the next prerelease build from May 10.
Please let us know if you need the patch immediately.

Thank you.

Thank you.

I can wait for the May 10th build. But will need a final build before June. We plan on deploying the latest of our product with Stimulsoft by June.

Let us know about the result.

Thank you.

Downloaded build from 5-10.

I can see the new property UseCache.

But there doesn't seem to be a method OnGetReport.

Am I missing.

The WebDesigner version is 2010.2.717.0

I got the OnGetReport method to show up...Just re-did everything.

Testing now to see if this eliminates the 2032 error. Will let you know later today.

Hello, Mike

Please use the GetReport event.

Thank you.

Hello, Mike

Let us know about the result.

Thank you.

I'm a little confused on how to use this new method.

You said to use it to Load the report. Do you mean the StiReport.Load() method. Where I pass in the byte array??

Any chance you could give me a quick example of how it's used.
