Clicking on the Value property of a Report Parameter from the Report Explorer in the .NET Standalone Report Designer throws the following error:

The issue is not present in the Standalone Report Designer for .NET Framework.

Good afternoon,

As per support ticket 1650746, could I please request that Telerik reporting could one day work with minimal APIs as opposed to controllers?

There is also the dependency on Newtonsoft for the JSON side of things. Up until trying to implement reporting, I had removed the Newtonsoft nuget package and was trying to use System.Text instead throughout my project. Perhaps in time, it could be a bit more agnostic when it comes to the provider.

Many thanks,

Rawden.

When a report contains multiple DateTime parameters, the viewer assigns the first value to all of them regardless of their default values or the values passed in the viewer's report source.

Additionally, if one clicks the preview button quickly after changing the value of a DateTime parameter, the old value is passed to the service even though the parameter editor is updated. To avoid this, the user needs to wait a second before previewing.

When testing integer values outside the range of System.Int32 (-2147483648 to 2147483647) for a multi-value integer parameter, I started to get the error:

An error has occurred while processing Report '___':
Cannot perform '=' operation on System.Int32 and System.Int64.

I narrowed this down to the "In" and "Between" operators. For example, the expression evaluating a literal integer value against the multi-value parameter:

= 0 In Parameters.IntegerMultiVal.Value

It appears that the literal integer is being converted, internally, to Int32 and compared against the contents of the multi-value parameter as Int64 - though the error only occurs when a value outside the Int32 range is present.

= Parameters.IntegerSingleVal.Value = 0

= Parameters.ZeroVal.Value In Parameters.IntegerMultiVal.Value

This was tested and reproduced in the HTML5 report viewer and the standalone report editor.

The HTML5-based report viewers use the following navigation icons.

• Arrow with a line to navigate to the next/previous page.
• Double arrows to navigate to the first/last page.
  

This is unintuitive and inconsistent with the desktop and native report viewers.
The navigation icons should instead be:

• Single arrow to navigate to the next/previous page.
• Arrow with a line to navigate to the first/last page.
  

When I render one of my reports I receive the error message  “A generic error occurred in GDI+”.

I figured out that one HtmlTextBox receives quite a long HTML from the data source - exceeds 32 768 characters. In my experiments, the error starts appearing if the text is longer than 32 775 chars.

In this case, the Reporting engine shouldn't throw a misleading GDI+ error but instead throw a more specific exception.

If you set the WinUI viewer's ViewMode to PrintPreivew in the XAML or the code, the toolbar button's state and value don't change. Hence, even though the report is displayed in PrintPreview, the button for switching the ViewMode is still showing 'Switch to PrintPreview' and is not highlighted. When you click it, the report is displayed in Interactive View, the button becomes highlighted and the tooltip states 'Switch to Interactive mode'.

The WebServiceDataSource wizard in the Web Designer doesn't let you construct Expressions for the Parameter values. The same functionality is present in the Standalone Report Designer.

The SqlDataSource Wizard of the Web Designer also allows the creation of Expressions for the Parameter values.

It would be convenient if the report creators were allowed to create the Expressions for WebServiceDataSource parameter values directly in the wizard. Currently, you need to type or paste the Expression manually.

Adding the "Telerik.ReportViewer.WinUI.Themes/Themes/Generic.xaml" theme to a WinUI project causes existing AppBarButtons to grow in size because it overrides the AppBarButtonContentHeight setting.

The report viewer theme should not override the styles of the default WinUI controls.

I have denied the permission to use the Asset Manager in the configuration of the service of the Web Report Designer. This is generally respected and I do not see the option to open the asset manager from the main menu but when I try to set an image to a PictureBox item, I still see the option to add it from the assets and the button is also clickable.

With that being said, the permission is respected on the server and I get an error about not having permission to use the Asset Manager when I click on the button. Still, it will be better if the button is removed from the UI altogether when I have disabled the assets.

The RTF rendering automatically switches to the Tables rendering mode whenever a Crosstab/Table/List is detected in a report. This rendering mode throws an exception whenever the report contains PictureBox with one of the following sizing options.

• Center
• Normal
• Stretch
• ScaleProportional

The RTF export should work with all PictureBox sizing options regardless of the rendering mode.

To work around the issue currently, one can either force the rendering engine to use the Frames rendering mode using the RenderingMode device information property or set the Sizing property of all picture boxes in the report to AutoSize.

we need to have complete End User Tutorial for Web Report Designer, where all the excel like features need to be demonstrated.

including Pivot etc.

When I deploy the Angular HTML5 Report Viewer demo on Docker and build for production I receive the next error:

When I remove the viewer from the project the problem disappears.

With the same 'Dockerfile' and 'nginx.conf' the Native Angular Report Viewer works as expected.

In the non-native angular report viewer we were using a customized template to change the order of the buttons and also to add custom buttons. We want to migrate to the Native Angular Report viewer but it lacks toolbar customization options. We need to be able to change the order and hide existing toolbar functions. Also we need the ability to define custom buttons with custom logic that executes when the button is pressed. 

I've tried to create a sub-class of the ReportingAngularViewerComponent and define a custom template for the toolbar, but the problem is that some of the core toolbar buttons (like zoom and pager) use custom local Telerik components that aren't exported from the ReportingAngularViewerModule, so I can't use those directly. 

It would be great if you can export all components used in the ReportingAngularViewerModule or provide an alternative way to customize the toolbar (may be similar to how you allow customization of the toolbar for the Editor control where users can define what toolbar commands are available, order them as they like and also define custom commands)

As an implementer, I sometimes need to trigger the Web Report Designer's commands programmatically. For example, saving the report definition when an external button is clicked.

Exposing an API for invoking the designer's commands would be of great help in implementing such functionality.
