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.
If there are parameters which are not mandatory, the reports automatically when loaded. In actual scenarios, there may be a lot of data being processed as the parameters may be empty. Developer should have an option on report level, say, AutoRun as true or false. The developer could decide if report needs to auto run. Thanks, Jai
At the moment, a whole words are removed from text until it becomes short enough to fit in the text box, and this is the only available behaviour.
There should be an option to put ellipsis or clip the text to the textbox width instead (like CSS text-overflow "ellipsis" and "clip").
There's also an older discussion here:

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 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.
Direct comparison to a single parameter value outside the Int32 range appears to work fine:= 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.
At the moment it's only possible to have your reports in old-fashioned projects.
It should be possible to add/design reports to SDK-style projects. That should work no matter what target framework is (.NET Core, .NET Standard or .NET Framework).
The HTML5-based report viewers use the following navigation icons.
This is unintuitive and inconsistent with the desktop and native report viewers.
The navigation icons should instead be:
When the input data of a pie chart is such that some of the series are insignificant enough not to be drawn on the surface area, a DocumentRenderException with the message "The operation was canceled" is thrown by the Reporting engine.
Enlarging the pie chart or hiding/removing its data point labels clears the error.
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.
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'.
If cells grow or shrink, if there are hidden cells, any time a report section grows vertically, the next section/table is not respecting the growing of the previous item and text prints in the wrong spot or the table overlaps the previous table.
A potential workaround is to manually convert the troublesome tables to lists where possible.
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.
