It would be great if the expressions were validated before leaving the expression editor rather than only finding out I missed a bracket ')' when running the report.

Currently the Webdesigner makes up to 6(?) and the Standalone Designer as much as it needs without(?) limit.

Especially the latter case can quickly lead to a lot of connections, saturating the max allowed connections of a sql server, which also leads to other services depending on a sql server connection to fail.

As far as I've seen, this only happens with Charts in Design mode.

So there are multiple ways to handle this:

• Being able to specify the max concurrent connections in the designer
• Make the usage of the DataSource more efficient by only loading the data once (like in the report viewer)
• Being able to turn off the chart preview in the Designer (By configuration, not with a user settable option)

See the attached report for a simple example:

It contains a single Datasource, which is a postgres query which simply waits 10s before returning the result.
After updating the DataSource to something which works for you and saving, simply reopen the report and see how many connections are opened in parallel.

I would like to formally request the ability to "sign" in some fashion a trdp/trdx file.  Note that if only the new file format is supported then that would be acceptable.

Basically, I would like to apply some signature that we could, if we so chose, read from the report file to verify that it was us that created or last modified the file.

If we need to use a separate tool to apply the signature other than the report designer, that would not be an issue.

The signature could be anything that Telerik/Progress decides we can use such as a code signing certificate, a strong name, etc.

Using the last modified time, or a hash value created from the current contents of the report file would not be a good solution as that would mean we would need to have a list of the hash values for each report and it would need to be updated every time the report is changed.
We are looking for something that could be applied to all reports that we create and that clients could not replicate.

This would need to be something that clients who we deploy the report files to cannot replicate and therefore if they modify the report file using the Telerik designer, it would remove that signature.  This way we can easily programmatically determine if the client has modified the report, and therefore prevent using it as if it is ours.

Note that we provide the ability to use custom reports in our application which are treated as separate from our core provided reports.  Also, I had posted to the forum asking if this is currently possible (https://www.telerik.com/forums/sign-telerik-reports).

Thank you.

.NET applications do not support rendering extensions like the XPS and MHTML rendering but the Reporting engine attempts to resolve them in such applications regardless.

There should be no attempts to resolve unsupported rendering extensions in .NET applications.

Telerik Reporting supports various Barcodes.

It will be very useful if it also supports out-of-the-box Radio Frequency Identification (RFID).

The blog RFID vs Barcode: Comparison, Advantages & Disadvantages elaborates on the difference between the Barcode and RFID and why the latter is preferred in some scenarios. 

Please provide an option to launch a sub report directly from within the main report designer (standalone version).
Example, in Crystal reports, if there is a sub report within a report, a user can double click that sub report and it opens it as a new report tab. This is very convenient rather then having to chase down the path to the subreport and open it manually.

I am using Kendo UI Spreadsheet control in our project to present Tabular contents that end user can easily modify just like a normal spreadsheet operations and I saved it in database using toJSON method provided by kendo spreadsheet.

When I will get the database driven JSON data from kendo spreadsheet as mentioned above,  I want to present it in Telerik Reporting using Table (Datasource of that Table will be from JSON data I saved earlier).

Currently there is no such feature available in Telerik Reporting and I would like to request that feature to be included in future release.

Thanks

I use HTML content like the below in an HtmlTextBox:

<a style="color: red" href="some link here">some text</a>

The color is not respected when I export to PPTX. The output color of the generated link is always the default blue. In the rest of the formats that support hyperlinks, the color is correct.

I tried to wrap the <a> tag also with <p> and <span> with the same color setting, to no avail.

I am using the Blazor Web Report Designer widget which when initialized, loads its theme based on the @progress/kendo-theme-default - npm (npmjs.com) theme and overrides the styles in my Blazor application. There is no way to disable the loading of the designer's theme and the application looks inconsistent as a result.

In the Standalone/Visual Studio Report Designers, the distances from the currently selected report item to the nearest elements can be shown by clicking the Show Dimensions button.

We would like to see this functionality implemented for the Web Report Designer too.

After installing the latest version, the WebServiceDataSource wizard does not send query parameters.

When the report is previewed, the WebServiceDataSource performs the request correct and the expected result is returned.

I followed How to set up in Blazor application | Telerik Reporting

All done! But when it run i got an error "telerikWebReportDesignerInterop.js 404"

<script src="_content/telerik.webreportdesigner.blazor/telerikWebReportDesignerInterop.js" defer></script>

and in console show:

When the non-native Excel page header and footer are used (the UseNativePageHeader and UseNativePageFooter XLSX options are set to False) and the SplitWorksheetOnPageBreak property is set to True, the page header section of the report is rendered only on the first sheet, while the page footer section of the report is rendered only on the last sheet.

All Excel sheets should have the page sections present.

If you trigger the 'Clear selection' button of the HTML5 Report Viewer parameter's area, there is no request for a report document with the updated parameter values and the viewer shows the previous report waiting for the user to select parameter values. This problem occurs with both Single and MultiValue parameters with AvailableValues that are non-nullable.

In the Standalone Designer and desktop viewers, in the same scenario, the preview displays a message indicating that the user needs to select valid parameter values.

I think navigating over pages by click is boring/complicated, scroll over pages seens to be the standard in the majority of applications.

I know that the HTML5 ReportViewer has the pageMode() property to solve this...

There's a way of implementing the PageModeProperty into the WPF ReportViewer?

I have a table with a detailed group with PageBreak set to 'After' and a crosstab inside the table with a row group that also has PageBreak set to 'After'. The pagination is respected in the preview of the designer, however, when exported to XLSX, there is only one worksheet generated.

If I remove only the PageBreak of the detailed table group, there is no pagination and the generated worksheet is only one.

If I remove only the PageBreak of the crosstab row group, there is pagination and the generated worksheet is correct in number. However, the content is not split as expected among the sheets.

If I make the detail table group static and remove its PageBreak, the pagination and the worksheets of the Excel document are as expected.
