Not all my business objects appear on the MVC report viewer.

[kgb2013]

Hello.

I have an MVC Viewer for displaying my bussiness object data:

Code: Select all

@Html.Stimulsoft().RenderMvcViewerScripts()
@Html.Stimulsoft().StiMvcViewer(
	"Reports",
	new StiMvcViewerOptions() {
		Controller = "List",
		ActionGetReportSnapshot = "GetReportSnapshot",
		ActionViewerEvent = "ViewerEvent",
		ActionExportReport = "ExportReport",
		ActionPrintReport = "PrintReport",
		Width = Unit.Percentage(100),
		Height = Unit.Pixel(1300),
		ClientRequestTimeout = 900000,

		BackColor = Color.DarkGray,
		MenuShowMode = StiShowMenuMode.Click,
		MenuViewMode = StiWebViewMode.OnePage,
		MenuAnimation = false,
		ShowButtonBookmarks = false,
		ShowButtonParameters = false,
		ShowButtonDesign = false,
	}

		private StiReport GetReport(ListModel model)
		{
			var docs = model.GetDocsStimulSoft();
			using(var report = new StiReport())
			{
				report.Load(MrtFilePath);
				report.RegBusinessObject("Document", "Document", docs);
				return report;
			}
		}

		public ActionResult GetReportSnapshot(ListModel model)
		{
			return StiMvcViewer.GetReportSnapshotResult(HttpContext, GetReport(model));
		}
)

My problem is that I get displayed only some of the business objects that I feed it (around 23 objects out of ~3000).
So I get only 2 pages instead of let's say 200.
Is there a limit setting somewhere?
When I was doing the same with SQL query stored in the MRT file I didn't have such problems.

Thanks.

I see now that I am disposing the report before returing it but now that I've changed that it still see only 23 entries:

Code: Select all

@Html.Stimulsoft().RenderMvcViewerScripts()
@Html.Stimulsoft().StiMvcViewer(
   "Reports",
   new StiMvcViewerOptions() {
      Controller = "List",
      ActionGetReportSnapshot = "GetReportSnapshot",
      ActionViewerEvent = "ViewerEvent",
      ActionExportReport = "ExportReport",
      ActionPrintReport = "PrintReport",
      Width = Unit.Percentage(100),
      Height = Unit.Pixel(1300),
      ClientRequestTimeout = 900000,

      BackColor = Color.DarkGray,
      MenuShowMode = StiShowMenuMode.Click,
      MenuViewMode = StiWebViewMode.OnePage,
      MenuAnimation = false,
      ShowButtonBookmarks = false,
      ShowButtonParameters = false,
      ShowButtonDesign = false,
   }

      private StiReport GetReport(ListModel model)
      {
         var docs = model.GetDocsStimulSoft();
         var report = new StiReport();
         report.Load(MrtFilePath);
         report.RegBusinessObject("Document", "Document", docs);
         return report;
      }

      public ActionResult GetReportSnapshot(ListModel model)
      {
         return StiMvcViewer.GetReportSnapshotResult(HttpContext, GetReport(model));
      }
)

I have now tried to use the advice from here :
http://stackoverflow.com/a/18373412/2173353

But this generates the following error:

...

In your demo here:
http://www.stimulsoft.com/en/articles/s ... ss-objects
..you don't mention anythig about a need to call SynchronizeBusinessObjects() so I guess that the post in Stackoverflow is wrong...

So, back to the begining...
Any idea what is missing here?
I also attach my MRT file.

EDIT:
The variable `docs` is an IEnumerable of my business objects.

I have news on this problem:
When I make the IEnumerable a List the problem goes away!

Code: Select all

report.RegBusinessObject("Document", "Document", docs.ToList());

I have noticed that when navigating to the last page of the report I get this error:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Hello,

Please check the last prerelease build. If the issue still present please send us a sample project which reproduce the issue for analysis.

Thank you.

I think this was solved by the time I used ToList().
If I see it again, I will let you know.

Hello.

Let us know if you have any problems else.

Thank you.

[kgb2013]

OK.
Here is a case where the exception:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

..happens:

When I use an MRT file that uses bussines objects, it happens when have my code like this:

Code: Select all

		public ActionResult GetReportSnapshot(ListModel model)
		{
			try
			{
				using (var report = GetReport(model))
				{
					return StiMvcViewer.GetReportSnapshotResult(HttpContext, report);
				}
			}
			catch
			{
				return null;
			}
		}
		//---------------------------------------------------------------------------
		public ActionResult ViewerEvent(ListModel model)
		{
			return StiMvcViewer.ViewerEventResult(HttpContext);
		}

If I make my ViewerEvent(..) like so the problem disappears (but I make unessesary DB calls):

Code: Select all

		public ActionResult ViewerEvent(ListModel model)
		{
			using (var report = GetReport(model))
			{
				return StiMvcViewer.ViewerEventResult(HttpContext, report);
			}
		}

It happens when moving to another page (from the initial/first page) and here is the stack trace:

at System.Collections.CollectionBase.System.Collections.IList.get_Item(Int32 index)
at Stimulsoft.Report.Components.StiPagesCollection.get_Item(Int32 index)
