In the standalone designer, it would be helpful if you could drag and drop the column headers to reorder.  At present you have to add a new column and delete the old one, remembering to copy all properties.

Make the Design-Time parameter values of the WebServiceDataSource editable through code.

Currently, the design-time values can be edited only by the report designers or by saving the report with the TRDX extension and editing the XML.

In the XML, to change the design-time values, you may edit the ParameterValues property which is a string.

What's the long-term plan for supporting Linux and Telerik Reporting? The dotnet design team is looking to remove support for System.Drawing.Common on Linux platforms. They're recommending compiler warnings in .Net 6, and full PlatformNotSupportedExceptions in .Net7

Release R2 2019 SP1

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.

Currently the Web Report Designer (WRD) can only work with reports stored on the server where the WRD Web API service is hosted.

A nice addition would be the option to select a local TRDX/TRDP file from the client file system and upload it to the server, when opening a new report for edit.
When saving such report there should be an option to download it to the client's file system as well.

With this approach the open/save operations will more closely resemble those of the standalone report designer.

I've noticed an issue with the web service data source configuration window when using jQuery version 3.5.1 or higher.

When you use the click on the Web Service Data Source from the left side menu it will open the configuration window in which Responding encoding and Data selector fields will be there for the jQuery version 3.3.1.

Now try the same steps with the 3.5.1 jQuery version or higher and those 2 fields won't be there.

The issue is reproducible in Standalone Report Designer which internally uses RadRibbonWindow. When the Auto-hide taskbar feature in Windows is enabled and the window is initially maximized, the RadRibbonWindow position is not correctly calculated and looks offset. Here's the corresponding issue in Progress® Telerik® UI for WPF Feedback Portal: RibbonWindow: The window is clipped when maximized initially and OS taskbar is auto-hiding.

The Could not retrieve Expression schema. error can be experienced while trying to set a value of textbox by using the expression editor.

Last Updated: 17 Nov 2021 16:25 by ADMIN
Currently, if you use an Expression to change the parameter's Text, it will be correctly evaluated only the first time when the report is rendered. Let's say you have 2 parameters- Parameter1 and Parameter2. The Text property of the second parameter is based on the Value of the first. However, if you change the value of the first parameter, then the Text of the second will not be updated.

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).

It would be very practical to have a component that could display HTML and CSS code from a data source.


Thank you

Hello Telerik team!

In the attachment, there are two PDFs, generated by the same template (also in attachment): one built under Windows, another one - under Linux (Docker). See red boxes as defects on the screenshot:

Currently, the row/record delimiter when exporting to CSV is taken from the environment. This way, the same CSV document will have different line separators when exported from Windows and Linux.

It will be very useful if the row delimiter can be specified in the device information settings the same way the field delimiter can.

It will be useful to have a function that can be used to keep the client session alive, for example by calling this function periodically to make requests to the service and thus to prevent the session from expiring.

Release R3 2021 SP1

Currently, the MsSqlServerStorage CommandTimeout is with the default value that is 30 s. In some scenarios, like when the Search functionality is enabled and the report is very big, the generated ClientSearchItemsResource may be too big, and when attempting to save it in the storage the latter may throw the exception 'System.Data.SqlClient.SqlException (0x80131904): Execution Timeout Expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.'

The error may be avoided if the CommandTimeout can be increased.
