When a report fulfills the following conditions :

 1. Is Multicolumn;
 2. Has DocumentMapText set;
 3. Contains a List (data item) with DataSource set with Bindings to a field of the Report DataSource.

and is displayed in PrintPreview mode in the WPF Report Viewer, an exception like :

"Could not register named object. Cannot register duplicate name '_20aa3785775c4790ba0cfa8021bd8433' in this scope.' Line number '1' and line position '2567'. Cannot register duplicate name '_20aa3785775c4790ba0cfa8021bd8433' in this scope." is thrown.

While processing, if Barcode item throws an exception (for example "Barcode is too large to fit!"), the report's Error event is not fired.

 

When a report with a document map is reloaded due to parameter change, the currently selected position in document map tree is lost and the current page number is reset to 1. Preserving the page number does not make sense, because changing a parameter may change the rendered pages count, hence there is no guarantee that the same page number will correspond to the previously examined page.

However, the viewer can persist the currently selected items hierarchy in the document map tree and try to select the same nodes after the report is reloaded. This would be particularly useful in Report Book scenarios where the book will navigate to the same report once the parameters are changed.

 

Steps to reproduce the problem:

1. Open the Report Book demo.

2. Navigate to Dashboard report by clicking the third item in the Document Map pane.

3. Change a report parameter, i.e. select 2002 in the Year parameter editor.

4. The viewer reloads the report book and navigates to its first page, clearing the highlighted items in Document Map pane.

We need the ability to automatically adapt report layout after its page size chages using report elements docking, anchoring etc. functionality.

This will allow us to reuse report templates for different printer paper sizes without making specific report for each paper size.

We do not have knowledge of internal report layout composition so a layout changes cannot be done with custom code, but need to be specified in reports directly.

 

Thank you

Do you have an updated road-map or plan to support Web assembly (WASM), especially Blazor? You already published Blazor articles in your blogs.

It will be a good idea to add a new report viewer based on Blazor, protecting the parameters between the viewer and its API controller.

Also, will be a very good idea to start your online report designer (like alternative products), based on web assembly

Hello,

 

A ReportViewer control compatible with the Kendo Angular UI Framework (not the Kendo Jquery..).
When importing the css files into a project using the new Kendo angular UI framework (ngx) a lot of the components
of kendo are getting broken.

Or is there some workaround?

 

Best regards

Marc

Suspend the data item error messages and show the NoDataMessage instead. When using a WebServiceDatasource and the used web service returns a response with 400, 401 and 404 HTTP codes.

I want to set an option to define dynamic column width. Currently we can set textbox width by bindings. But makes different column with different height.

I need an option to set line height for contest in report.

I suggest that when saving reports as trdx files (trdp files are no good as they are compressed), that you save the SQL on multiple lines as it appears in the designer to enabled version comparison, i.e. git history of the file's changes can show the changes to the SQL.   Currently the SQL is on one line making it difficult to see the history.

Use only components from KendoUI for Angular. It would be understandable that such report viewer would provide less features, but it would remove dependency from jQuery and KendoUI for jQuery.

Add the new Crystal theme to the theme ResourceDictionaries available for the WPF and Silverlight ReportViewers. 

Actually multi value parameters is not supported on WebServices source. Multi value are passed as [string1,string2] instead of $paramName=string1&paramName=string2.

Multi value has to be passed on query string on correct way!

Loading huge DB schemas in bulk is time-consuming. Add lazy schema loader for the table column definitions in order to improve the user experience when using DB with a huge schema.

Please add support for signing PDFs with a certificate stored on a hardware token, for example on a Qualifies Signature Creation Devices (QSCD) as defined by the EU law known as EIDAS, using a native platform way (on Windows this might mean through the Certificate.msc store).

Support generating reports on .NET Core running on a non-Windows platform, esp. macOS or Linux-like OS.

There is the newly introduced WebServiceDataSource which enables me to get JSON data from a web service. I'd like to be able to use JSON as a data source for a report without using a web service. For example, the JSON might be embedded inside the report definition, or it might be coming from an external text file (URI or URL), or even pass it programmatically to the report at run-time.

It would be really useful if EntityDataSouce was updated to support Entity Framework Core contexts. EF Core depends on Standard 2.0 so can run on .NET Core or the full framework.

In some cases, the data source might have dynamic columns meaning that the columns might change for different report runs. I need to be able to detect if a particular column is available using an expression so that I can handle its absence without showing an error to the end user.

It would be nice if resx files to localize the (wpf) report viewer can be placed in a specific resource path instead of the main folder of the VS project.

For example a 'Resources' folder within the 'Properties' folder of the VS project.
