The data coming from a JsonDataSource component has null values for a date field. Using the (IsNull, ??, IIf) to check for null does not seem to work. For example: =IIF(Fields.actualWorkHrs Is NULL, "T", "F") always returns false even when there are null values in the actualWorkHrs field.

I would like to be able to do this syntax: Fields.Address?.State.  If address is null, then it is the same as state being null.  Instead of displaying an error, it would just show blank.

The fields of the report's data source are not available in the DocumentName evaluation context. It would be helpful if one can use an expression like =First(Fields.ClientName) for DocumentName.

I put a ReportViewer in an application and VisualStudio inserted the required MergedDictionaries.  I updated them to the Green theme and added the Green reference, now I get a XAML error stating Cannot find resource named 'RepeatButtonStyle.'  I comment out this line in my App.xaml file:

<!--<ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Green/Telerik.Windows.Controls.Navigation.xaml" />-->

the error goes away and my XAML designer works again, but the navigation section of the report viewer has the incorrect theme applied.

I looked in the copy of the file that is on my computer located at:

   C:\Program Files (x86)\Progress\Telerik Reporting R2 2019\Wpf\Themes\Green\Telerik.Windows.Controls.Navigation.xaml

On line 8831 there is a reference to a Static Resource named RepeatButtonStyle.

<Style x:Key="TabbedWindowScrollButtonStyle" TargetType="RepeatButton" BasedOn="{StaticResource RepeatButtonStyle}">

I assume this the culprit?

There was a similar issue in February.

Telerik saving to PDF issue intermittently.  The issue is that the graph gets skewed and then won’t open in Acrobat once the report is exported.

We use Telerik's report books extensively - and find that to be a very powerful way to create dynamically generated reports.

The feature request is: if a report's datasource doesn't fetch any rows don't add a blank page to the report book.

Go to page

Open search dialog.

Try to move search dialog pressing left mouse button on search dialog title.

Incorrect behavior: search dialog disappears and appears again only when you finish pressing left mouse button.

Go to page

Open Search dialog.

Type "Accessories" in search field. Wait for results.

Pick last result (Accessories - page 2) from results list. (page 2 will be opened - correct)

Close search dialog and open it again (or just clear search field).

Type "Accessories" in search field again. Wait for results.

Pick last result (Accessories - page 2) from results list again.

Incorrect behavior: page 1 will be opened instead of page 2; and first result item will be highlighted as selected instead of last result item.

Also I met situation when long results list was scrolled up to top but it was unclear how to reproduce it stable.

It would be very helpful for us people that have been using Telerik Reporting in Silverlight (or WPF) applications to have access to a Report Viewer for Windows Store Apps (XAML).  The future of Silverlight is unclear at least and there are many Line Of Business Applications currently running under Silverlight and I know of many developers that are looking to port their LOB apps to Windows Store Apps (or Universal Apps).  The current HTML5 Report Viewer does not provide printing when it is implemented in browser window in Windows Store Apps so we cannot really offer this option to our customers.

It would be nice, if not required by our client, to have 100% Web-based, Rich, Ad-hoc Reporting Solution.
Something similar to the one in ComponentOne Active Report

Why is it that the telerik report designer is locked down and cannot be used as a set of controls in a custom application as any other telerik control. We would like to use the report designer controls in an application we make to give it our look and feel and so we can give it the functionality we require. Why limit your customers by locking down your report designer. One of the great things about telerik is a great set of products and customer support. If we had a way to get at the Telerik.ReportDesigner.Core.dll we can figure our where the controls are and display them in our app. I don't understand the marketing behind the locked down report designer. How does it benefit your customers? You can still have a locked down designer for those customers that don't want to customize it. Providing access to Telerik.Reporting.Core.dll will give your customers the ability to customize the report designer to their needs. Telerik sells controls that customers use to make applications that they sell, so whats the difference with the designer?

A Reporting engine should expose the ability to control the layout of the table of contents\Document Map. Reports are not always data driven and should give the ability to display the contents of the report at different levels, much like Microsoft Word does with their table of contents.

The Labels to be displayed on a Numerical Scale Axis are currently set automatically.
The user can control the scale range via Axis Scale Minimum and Maximum properties. The user can control also the Label Step.
However, the exact Axis Labels to be shown are calculated automatically and cannot be controlled directly by the user.
For example the user cannot force the Axis Labels to start from the Minimum value.

Is it possible to do the conditional formatting of a text watermark? For example, I am checking if the parameter value is equal to Passed, then font color of watermark should turn green else it turns red.

If the command for fetching Report Parameter AvailableVlues times out, the WPF Viewer freezes with hidden parameters' area, i.e. it is not possible to enter other values and the application needs to be restarted.

When a report contains data item bound to big amount of data, it takes time to export in CSV format due to data denormalization.
This would be a performance improvement for big data reports.
