Report Book, Report Instances and Parameters

Hi there,

After having some issues figuring out how to get multiple reports in a single document, I finally stumbled onto the ReportBook class.

I have implemented a number of different single page report documents and have, up until now, had no trouble adding them to the book and getting them to display. The issue that I've come across is that I have one derivation of the report that requires three separate instances of a single page, so

public class MultiSheetReport_Group1 : Telerik.Reporting.ReportBook

{

public MultiSheetReport()

{

this.Reports.Add(new CoverPages.GroupOneCoverPage());

this.Reports.Add(new ItemizedPages.GroupOneItems());

}

now, I have an Group that requires a monthly breakout of the itemized page, so there is a GroupFourItems report that takes in both the id to read as well as the month value that I would like to print that report for. The issue that I am having is that for each instance of the Monthly Report, the same value is being sent to the ObjectDataSource constructor for the month value.

I've attempted to create another constructor for the MultiSheetReport() like so:

public MultSheetReport(int parentId)

{

var monthTriplet = DateTimeHelper.GetMonthOrdinals(parentId);

// monthTriplet is a Tuple of int, int, int

var cvrPage = new CoverPages.GroupOneCoverPage();

cvrPage.ReportParameters.Clear();

cvrPage.ReportParameters.Add(new ReportParameter("id", ReportParameterType.Integer, parentId));

this.Reports.Add(new CoverPages.GroupOneCoverPage());

var m1ItemPage = new ItemizedPage.GroupOneItems();

m1ItemPage.ReportParameters.Clear();

m1ItemPage.ReportParameters.Add(new ReportParameter("id", ReportParameterType.Integer, parentId));

m1ItemPage.ReportParameters.Add(new ReportParameter("month", ReportParameterType.Integer, monthTriplet.Item1));

this.Reports.Add(m1ItemPage);

var m2ItemPage = new ItemizedPage.GroupOneItems();

m2ItemPage.ReportParameters.Clear();

m2ItemPage.ReportParameters.Add(new ReportParameter("id", ReportParameterType.Integer, parentId));

m2ItemPage.ReportParameters.Add(new ReportParameter("month", ReportParameterType.Integer, monthTriplet.Item2));

this.Reports.Add(m2ItemPage);

}

and so on...
The first problem is that the parameterized constructor for the reportbook is never called as the report, only the default constructor. This leads to the second issue which is that when I put a breakpoint on the constructor for the ObjectDataSource that backs the ItemizedPage.GroupOneItems report class, the exact same value is passed in for each of the months. I'm not entirely sure how to fix this.

Any thoughts?

Thanks.

Dynamic Chart Height based on data rows

Hi,

Is there a way to dynamically set the chart height based on the number of data rows? The chart looks fine when there are about 10-12 rows of data, but anything more and it starts to squish to meet the height requirements of the chart. I'm assuming there is a way and I'm just missing it!

I'm using the standalone Telerik Report Designer FYI. I've attached photos for an example.

Using report book with properties

Hi, I have a report act as a header template as follows:

var template = new TemplateReport{ Header = "Some header"};

where updating the custom properties will also update the textbox value.

When I want to use the template, I will just create the template, and do the such things:

var template = new TemplateReport{ Header = "Some header"};

var content = new ContentReport();

template.Content = content;

How can I do such things with report book? Thanks!

Backward Compatability, will it break???

We have a legacy web application leveraging "Telerik Reporting Q1 2015 SP1 (version 9.0.15.324)" and would like to bring it up to date with the current version "Progress® Telerik® Reporting R2 2019 SP1 (13.1.19.618)".

I have not been able to find anything to indicate what, if any, breaking changes were introduced in more recent versions or any other pitfalls we may face thus it is difficult to plan the effort or weigh the value.

Does anyone know if the newest version is backward compatible with version 9.0.15.324?

Thanks in advance,

Matt

Hiding error messages from end users

Hi there,

I'm new to Telerik Reporting and I'm building a report that shows a list of images. The images are uploaded from a mobile app, processed, and then are made available to be displayed on the report.

In some cases there could be an issue with the processing and the image file is not available or the processing hasn't completed yet before the report is executed. In this case I would rather display nothing than the big red error message that shows when the image can't be found. Is there a way for me to suppress this message somehow?

I've attached a sample of the error message.

Thanks for the help,

Greg
