I want to set the Table ColumnWidth to a particular value in the Properties of the Web Report Designer. There is no property ColumnWidth as in the Desktop designers, and I tried to set the Size.Width, which is available.

When I increased the Width from the Properties, in design time, there is no change in the column width, only dashed borders indicating the new size when selecting the corresponding TextBoxes. In runtime, though, the new size is respected.

The inconsistency repeats even when I open the saved report in another browser or through another application, hence this is not a caching issue.

My application uses RadDocking. When the WPF Report Viewer is hosted in RadDocking, some Graph labels appear cut.

The problem is related to the property UseLayoutRounding="True" in the RadDocking.

The workaround is to use the following setting:

RadPane pane = new RadDocumentPane();
pane.UseLayoutRounding = false;
pane.Header = "Report";
pane.Content = reportViewer;
DocumentPaneGroup.AddItem(pane, Telerik.Windows.Controls.Docking.DockPosition.Center);

I am working with a static report (not using tables or groups), and I need to set the Level / TOC Level under the Interactivity section for an HTMLTextBox.
However, in my report, the Interactivity options do not show any property for Level. I am only seeing basic properties like Action, BookmarkId, DocumentMapText, TocText, etc.
The Level field is completely missing.

I have a crosstab with a dynamic number of columns (time periods) that can exceed 15-20 columns. When exporting the report to PDF in A4 landscape format, excess columns are truncated and never printed on additional horizontal pages.

The issue is related to the Crosstab property 'RowHeadersPrintOnEveryPage'. When set to True, it places additional row headers on each page when using physical pagination. I suspect these additional headers are not taken into account when calculating the necessary page area, hence the final part of the Crosstab is skipped.

Release 19.3.25.1119

I have created a report parameter that accepts null as a value(AllowNull=True) and have set null as the default value by using the expression =Null on the Value property of the report parameter.

This report parameter also has a data source assigned to it so it has available values. Here is a look at the full setup:

When I call the "getReportParameters()" function on the HTML5 Report Viewer, there is an exception thrown in the console that looks as follows:

telerikReportViewer:1 Error: The available values of parameter Parameter1 do not contain Value property that equals null

I have projects on .NET Core and I want to use the System.Text.Json serializer that is the new default, but reporting relies on Newtonsoft.Json.

---

ADMIN EDIT

There are two approaches that can be taken right now to solve this:

OPTION 1: define separate endpoints (services, projects) for the different tasks - they can still use the same database layer through a shared project, depending on the architecture you have. This would let you have separated services with the appropriate serializers without custom attributes and code (see below). For example, create a separate project for the reporting REST services.

OPTION 2: add some custom decoration on the endpoints so you can choose which serializer is used on each, you can find some examples here: https://stackoverflow.com/questions/59650907/how-to-configure-two-json-serializers-and-select-the-correct-one-based-on-the-ro - the point being to register a serializer depending on the endpoint based on your own code rather than let the framework put one in for all endpoints.

NOTE: This would be a breaking change.

In MSSQL, you may use syntax like 'StoredProcedureName;1' to indicate stored procedure versioning, but it is not yet supported by Telerik Reporting.

I use such syntax and need to remove the version to make this work in Telerik Reporting.

It would be great if you also added support for versioning in MSSQL stored procedures.
