Trying to preview a report with a lot of data in the report viewer in an ASP.NET Core application results in the error:

"System.ArgumentException: The JSON value of length n is too large and not supported."

Consider adding functionality that allows for loading Assets into the Asset Manager from code. 

I would prefer to store assets in a database and load them up for a user.

Makes more sense than randomly loading them from whatever computer you are working on.

The Web Report Designer uses a subset of all available Kendo UI widgets. It will be useful to have a documentation article listing all of them, just as it's done for the HTML5 Report Viewer here: Kendo Widget Requirements.

This way the users will have better understanding which Kendo UI classes and components are used by Web Report Designer and will enable them making their own distribution packages when needed.

If you add the 'kendo.common.min.css' that is required for the Html5 Viewer to the page with the Web Report Designer, the latter Menu styles get broken.

Due to this, if you need to have both the viewer and the designer in the same project and cannot have scoped styles, the appearance of one of them will be broken.

It takes 2+ seconds between "info" polls to the server. This should be a much smaller interval. Maybe .5 or .25 seconds.

Telerik's own ReportClient example shows a 500ms interval between info polls...

        private static byte[] GetDocument(ReportClient restServiceClient, string instanceId, string documentId)
        {
            bool documentProcessing;
            do
            {
                Thread.Sleep(500);// wait before next Info request
                documentProcessing = restServiceClient.DocumentIsProcessing(instanceId, documentId);
            } while (documentProcessing);

            byte[] pdfDocumentBytes = restServiceClient.GetDocument(instanceId, documentId);

            return pdfDocumentBytes;
        }

It would be very useful if custom size and arrangement of the tool panes could be remembered by the Standalone Designer. 

In particular it would be useful for the property pane and it's popup windows (e.g. Graph Series Connection Editor)

In some scenarios, it would be helpful to have the path to the report available, for example, as a Global Object, so that you may use it in the Expressions.

Here is a use case. The PictureBox resolves relative paths with respect to the report's folder. Currently, if you want to check whether an image that is in the report's folder exists by its name only, you need a custom user function. If you know the report's folder, you may do this with System functions.

In some cases, the textbox width will be nearly but not enough to fit the whole string and as a result, the textbox will grow and will thus push the items below it further down.

In Page Sections, this may even result in some of the items that are near the bottom not being displayed at all.

It would be great if there was a warning when the width is not enough so that such scenarios are avoided.

There should also be an option to disable the warnings.

The path for window.kendo in initExpDeps.js is incorrect. This does not always lead to error. When there's an error it can be the following:

Module not found: Error: Can't resolve '.\telerikReportViewer.kendo.min'" in "ERROR in ./node_modules/@progress/telerik-angular-report-viewer/dist/dependencies/initExtDeps.js

Bindings to the TitleStyle property of a ToC section result in the following error:

 Bindings error - The value of property 'TitleStyle' is null

We have implemented custom storage (IDefinitionStorage) with the SaveDefinition method where it saves the edited report in a custom way. There can be some validations and save can fail. For this, I am just throwing a new Exception. The error message is showing in a general way, and it doesn't show my custom message.

Telerik report is showing error -

Method Name: Telerik.reporting.PictureBox.Set_Value - Parameter is not valid. 

 Above highlighted line gives an error during component initialize.

It was working earlier, but now showing this error, even there is no code change. Please help.

Your help is highly appreciated.

 In the Word rendering, there is sometimes space between the footer and the body of the document.

Please, add a .zip or .7zip with the following content from the Telerik Reporting folder:

• all runtime assemblies- everything from the Bin folder without the Design folder and VS<Version> (for example VS2019, VS2022, etc) folders
• Html5 folder
• License Agreements folder
• Silverlight folder
• Wpf folder
