If you add two Bindings for the same property in the designer when you click OK, an error "Index must be within the bounds of the List. Parameter name: index" occurs and the Bindings are ignored.

When Kendo version 2023.1.314 is used, the tooltips of the HTML5 Report Viewer and its wrappers flicker when the cursor hovers above them.

Telerik Reporting Version: 17.0.23.315

The following error is thrown during design time when a Barcode has a static value but one or more of its properties are bound to a report parameter through Bindings.

When actually previewing the report, the Barcode works as expected.

I need to know when one of my users has canceled the rendering of the report in order to update the UI accordingly.

Please consider firing a 'renderingCanceled' event when the above occurs or passing an additional parameter to the updateUi event to specify the rendering state.

The attached 'Test.svg' image markup file contains 'use' statements that lead to duplicating part of the image parts when rendering the report in PDF.

The other file in the archive, 'Test-noUsings.svg' is the same image without 'use' statements and doesn't have this problem.

If the CanGrow property of a TextBox/HtmlTextBox is set to True and Left and Right Anchoring is applied, the Height of the text box will be determined based on its design-time Width.

Thus, even if the actual final Width of the item is enough to fit its contents on a single row, the text box can have a larger than necessary Height.

React Report Viewer throws error ts(7016) on importing it in a TypeScript project:

Could not find a declaration file for module '@progress/telerik-react-report-viewer/dist/cjs/main'. 'C:/Users/dnikolov/Desktop/ReactTypesScript/my-app/node_modules/@progress/telerik-react-report-viewer/dist/cjs/main.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/progress__telerik-react-report-viewer` if it exists or add a new declaration (.d.ts) file containing `declare module '@progress/telerik-react-report-viewer/dist/cjs/main';`

While some viewer options such as the pageMode, viewMode, etc. are already exposed and configurable through code, the parameters are not. This means that the viewer will always load the report with the default report parameter values which can troublesome.

For example, I need to be able to pass a JWT to a WebServiceDataSource inside my report and I use a report parameter for doing so. This works as expected when I use a simple report viewer but when the report is loaded by the Web Report Designer, it is not possible to pass a value from the front end where the designer is initialized.

Currently, the ReportDesignerControllerBase class does not enforce its own JsonSerializerSettings, rather it uses the ones set globally, on the application level. This could potentially lead to errors since the Web Report Designer requires the data to be serialized in camelCase. When PascalCase is used, certain functionalities get broken.

A way to avoid this would be to explicitly define JsonSerializerSetting in the ReportDesignerControllerBase class so that the Report Designer service does not break regardless of the setting defined on the application level.

When rendering a report with a Graph on Linux, the labels of the Graph are not aligned properly.

For example, right-aligned labels are offset to the left depending on the content and length of each label.

I apply the operator TOP N (=5) to get only the first 5 records of a dataset sorted by a DateTime field. It sorts the data correctly as seen in the previewed report, but still returns all data records rather than the first 5 of them.

If I apply the TOP % operator, the dataset seems filtered as expected.

The workaround I have found is to apply second TOP N filtering with an empty expression as seen in the linked screenshot.

I have attached also a sample report demonstrating the issue and the workaround.

Error: Unable to cast object of type 'Telerik.Reporting.Processing.Expressions.ProcessingEvalProvider' to type 'Telerik.Reporting.Expression.IValueObject'

is thrown on previewing the data source results in the WebServiceDataSource when the Runtime or Design time expressions are left completely empty or the runtime value is a report parameter with an empty Value property.

When exporting a graph that has multiple line series and a category scale to CSV, the error "object reference not set to an instance of an object" is thrown.

More specifically, the issue occurs when one or more of the series do not have a corresponding non-null value for every category.

Hello Support-Team,

in the WebReportDesigner, the Edit-Window shows "undefined" for the FieldNames, when selected a second Time.

This is also reproduceable in the demo application: https://demos.telerik.com/reporting/designer.

(see Screenshot in attached Files)

Steps to repoduce:

1. Open the Edit-Window for a TextBox (with a DataSource)

2. Select the DataSource-Entry.

3. Select some other Entry, e.g.  "Report Parameters"

4. Select the DataSource-Entry.

Best regards
