I have a PictureBox item with a background image and no image value. When rendering in either of the Excel formats from a web application or from the Standalone designer, they throw an "Object reference not set to an instance of an object." exception. Here is the response from Fiddler:

{"message":"","exceptionMessage":"Object reference not set to an instance of an object.","exceptionType":"Telerik.Reporting.Services.Engine.DocumentRenderException","stackTrace":"   at Telerik.Reporting.Services.Engine.Document.GetDocumentInfo()\r\n   at Telerik.Reporting.Services.WebApi.ReportsControllerBase.GetDocumentInfo(String clientID, String instanceID, String documentID)\r\n   at lambda_method(Closure , Object , Object[] )\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass6_2.<GetExecutor>b__2(Object instance, Object[] methodParameters)\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ExecuteAsync(HttpControllerContext controllerContext, IDictionary`2 arguments, CancellationToken cancellationToken)\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ApiControllerActionInvoker.<InvokeActionAsyncCore>d__1.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ActionFilterResult.<ExecuteAsync>d__5.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()\r\n   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n   at System.Web.Http.Controllers.ExceptionFilterResult.<ExecuteAsync>d__6.MoveNext()"}

When configuring a WebServiceDataSource in the Web Report Designer in ASP.NET,  upon previewing the data there is an error '404 Not Found". The same web service was successfully resolved by the Standalone designer and in the ASP.NET Core demo.

The data source fields were visible and usable in the designer also under ASP.NET Web Report Designer.

The issue occurs when a report contains a subreport with InstanceReportSource set as its ReportSource. If the report definition in this InstanceReportSource contains data sources, they will be serialized as DataSourceRef objects instead of using their actual type names like EntityDataSource, CsvDataSource, etc.

The issue is reproducible only in Standalone Report Designer, i.e. serializing/deserializing the report definition programmatically would work as expected.

The issue is introduced in Telerik Reporting R1 2019.

Currently, you may aggregate values from a certain scope for a particular page with the Page function PageExec. It would be great to be able to display also the carryover aggregates up to the current page. 

For example:

Page 1: Page1 Sum = 10; Total Sum at the end of the page1 = 10
Page 2: Page2 Sum = 5;   Total Sum at the end of the page2 = 15
Page 3: Page3 Sum = 13; Total Sum at the end of the page3 = 28

If you set a DataSource for the Report Parameter AvailableValues and try to configure the parameter ValueMember or DisplayMember, the corresponding editor in the Web Report Designer displays the report DataSource instead of the parameter DataSource. For that reason, the correct fields cannot be selected from the editor and must be typed manually. The linked video demonstrates the problem.

Steps to reproduce the issue:

1. Create a new report in the WebReportDesigner;

2. Add a simple CSV DataSource (for example with Item and Value columns);

3. Select the Table Wizard and set the CSV DataSource as a Value of the DataSource property;

You will notice that the names of the columns from the datasource are missing.

 

I created my own ADO.NET Cache Provider. I have found that when a report is being generated programmatically and it failed over SQL timeouts it doesn't clear the session_state table.

When we render our report in PDF or preview it in PrintPreview mode in the viewer, the last page may be lost.

The issue can be reproduced in the attached sample report. In it, the Visible property of the Detail1 and Detail2 cells is set to False. When you export the report to Word, the DOCX file is broken. 

Steps to reproduce:

1. Download and run the attached project in IE or Firefox

2. Write in the field for example "haha" and click the button.

3.Scroll down and you will notice that the headers are not frozen.

Steps to reproduce:

1.Download and run the project

2. If the scaleMode is FitPage, the report doesn't appear

3. If the scaleMode is FitPageWidth, the UI seems to be broken

You can check the attached video for further reference.

 

Please add a property "ToolbarVisible" to WPF ReportViewer. Most of the cases the buttons are not useful or should be replaced by some custom toolbar. 

The SearchDialog is placed based upon a parent window of type "Window". However, when I use other types like "RadRibbonWindow" as my main window the placement does not work correct. As a result the SearchDialog is shown in the upper right corner of the desktop. This is the code (in SearchDialogController.cs):

        Window GetParentWindow()
        {
            return (this.model.PageScrollViewer == null)
                ? null
                : this.model.PageScrollViewer.FirstParentOfType<Window>();
        }

At least this method should also take RadRibbonWindow in account (this is certainly not used that rarely since we all use Telerik components!) or for a more generic solution look for types that are derived from Window.

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

In my scenario, I save the ReportSource instances in a dictionary in the custom ReportSource Resolver:
However, I have no chance to delete the memory because there is no event or flag to see when it is not needed anymore.

The editor for parameters can be set for each type of parameter, but not individually for each parameter.

This means if there are two parameters that both have availableValues and have multiselect set to false, different editors can be set for each of these two parameters.

Exporting a report from the Report-Viewer to Word(docx), then opened in Word for Web (browser-version of Word) causes incorrect rendering of the document. Images are replaced with placeholders.

In comparison, exporting the report as PDF, then opening and converting it to Word and uploading it, renders much more correct and with images.

In .NET Core the localization routines have changed and the approach to localize an application provided in the documentation doesn't work.

When adding the localized .resx files as described in the documentation - with BuildAction set to None - the resource strings cannot be obtained and even the default string values are lost. This effect can be mitigated with changing the BuildAction to EmbeddedResource.
