HTML5 ReportViewer and single report page displays

Using the HTML5 ReportViewer in MVC

Aiming at finding a way to force the whole report to display in just one long scrolling page without interfering with how it may show up when printed.

The report being displayed is in a reportbook which switches between landscape and portrait orientation and it made up of ~ 19 report/subreports.

What is happening is that certain page breaks are showing up that push the contents onto additional pages even though the viewer is in ViewMode.Interactive .

Is there a listing anywhere of what reporting elements/settings/etc may be causing these breaks even in Interactive mode?

Is there any way to truly force the reportviewer to have everything on only a single page?

Here's the viewer code being used:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Telerik MVC HTML5 Report Viewer</title>

<meta http-equiv="X-UA-Compatible" content="IE=edge">

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1" />

<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>

<link href="http://kendo.cdn.telerik.com/2015.3.930/styles/kendo.common.min.css" rel="stylesheet" />
<link href="http://kendo.cdn.telerik.com/2015.3.930/styles/kendo.blueopal.min.css" rel="stylesheet" />

<script src="@Url.Content("~/ReportViewer/js/telerikReportViewer.kendo-11.0.17.118.min.js")"></script>

<style>
#reportViewer1 {
position: relative;
width: 1300px;
height: 900px;
font-family: Verdana, Arial;
}
</style>

<script src="@Url.Content("~/ReportViewer/js/telerikReportViewer-11.0.17.118.min.js")"></script>

</head>
<body>

@(Html.TelerikReporting().ReportViewer()
.Id("reportViewer1")
.ServiceUrl(Url.Content("/api/reports"))
.ReportSource(new TypeReportSource() { TypeName = "ReportLibrary1.ReportBook_Oriented, ReportLibrary1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" })
.ViewMode(ViewMode.Interactive)
.ScaleMode(ScaleMode.Specific)
.Scale(1.0)

.PersistSession(true)//NOTE: If this is False it clears the site sessions so it may no longer be used
.PrintMode(PrintMode.AutoSelect)
)

</body>
</html>

Subreport binding to parent report objectdatasource. Seeing the sub report, but there's no data in it

I'm almost there. Subreport is displaying but theres no data in it. What am I doing wrong please?

Winforms. ObjectDatasource using a dataset with 2 tables, master and detail.

My report represents a paper questionnaire/Form. Master is a single row table with a person's personal details eg name, address etc. The details table is multi row and represents the questions and answers that the person filled out. The tables are linked by an ID field. Ive added the ID to the filter field. For testing purposed I've created a dummy main and multi detail records.

Main report designer file entries

//

// HealthQuestionnaireDataSet

//

this.HealthQuestionnaireDataSet.DataMember = "MainDetail";

this.HealthQuestionnaireDataSet.DataSource = typeof(pulse.move.datasources.datasetHealthQuestionaire);

this.HealthQuestionnaireDataSet.Name = "HealthQuestionnaireDataSet";

//

// subReport1

//

this.subReport1.Name = "subReport1";

typeReportSource1.Parameters.Add(new Telerik.Reporting.Parameter("parmId", "= Fields.Id"));

typeReportSource1.TypeName = "pulse.move.telerik.reportlib.RptHealthQuestionnaireSubDetail, pulse.move.telerik.reportlib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null";

this.subReport1.ReportSource = typeReportSource1;

I call the following static method in the code behind of my main report to generate the report onto the ReportViewer using the dataset passed in. This seems to work correctly. If I change the code to read "var report = new RptHealthQuestionnaireMainDetail { DataSource = dataset };" then it fails to generate. I wondered if this was the cause of my problem with the sub report not working.

public static void GenerateReport(datasetHealthQuestionaire dataset, ReportViewer viewer)

{

viewer.CancelRendering();

var report = new RptHealthQuestionnaireMainDetail { DataSource = dataset.maindetail };

var reportSource = new InstanceReportSource {ReportDocument = report};

viewer.ReportSource = reportSource;

viewer.RefreshReport();

}

I wasn't able to get the subreport to work in the designer, so I moved the binding code to the constructor of the sub report to make it easier to debug and change.

The subreport displays the labels correctly, but there's no data. What am I missing to bind the data correctly?

public RptHealthQuestionnaireSubDetail()

{

//

// Required for telerik Reporting designer support

//

InitializeComponent();

Bindings.Clear();

// tried both of the following. Makes no difference. Still no data

//Bindings.Add(new Telerik.Reporting.Binding("DataSource", "=ReportItem.DataObject"));

Bindings.Add(new Telerik.Reporting.Binding("DataSource", "=ReportItem.Parent.Parent.DataObject"));

}

//

// RptHealthQuestionnaireSubDetail

//

// Commented out the following 2 lines and moved them to the constructor

//this.Bindings.Add(new Telerik.Reporting.Binding("DataSource", "=ReportItem.DataObject"));

//this.DataSource = this.HealthQuestionnaireDataSource;

this.Filters.Add(new Telerik.Reporting.Filter("= Fields.Id", Telerik.Reporting.FilterOperator.Equal, "= Parameters.parmId.Value"));

this.Items.AddRange(new Telerik.Reporting.ReportItemBase[] {

this.detailSection1});

this.Name = "RptHealthQuestionnaireSubDetail";

reportParameter1.Name = "parmId";

reportParameter1.Type = Telerik.Reporting.ReportParameterType.Integer;

this.ReportParameters.Add(reportParameter1);

Picturebox Sizing

After updating to the latest version of reporting, all of my logo's that were in the top left of my reports are now scaling differently. It doesn't matter what size I set the images to or what options I set. I also tried changing the image to be the exact size it needs rather than just scale to fit. Has anyone else had a similar issue? If so any steps on how to fix it?

Querystring parameter

I have Web Forms report viewer ASPX and I'm trying to set a parameter "Parameter1" included in the designer like this:

if (!IsPostBack)
{
int AppointmentID = Convert.ToInt16((string)Request.QueryString["AppointmentID"]);
ReportLibrary.ClientApptInvoice rpt = new ReportLibrary.ClientApptInvoice();
rpt.ReportParameters["Parameter1"].Value = AppointmentID;
}

when I run the report viewer page I get "Missing or invalid parameter value" and the parameter field which is set visible appears to allow entry.

What am I missing ? I was trying to follow this - http://docs.telerik.com/reporting/designing-reports-parameters-programmatic-control

Thanks
