Currently, the WinForm report viewer fetches configuration (specifically the connection string for any named connection strings defined in reports) directly from appsettings.json, however, it would be useful if the report viewer could take into account an injected IConfiguration since there are scenarios where the configuration may not exist in appsettings.json or a preferred or more up to date user selected value has been added to the configuration from a different source (such as a userSettings.json or secrets.json).

Some background of my use case:

I have a desktop WinForms application targeting .NET 8.0. It usesTelerik.Reporting 19.2.25.813 and Telerik.ReportViewer.WinForms 19.2.25.813 to display reports.

The reports are TRDX files designed with the 64-bit version of "Report Designer".  The report viewer is being displayed in a dedicated WinForm named FrmReport which configures the reportViewer control to use a UriReportSource pointing to the folder on the user's C:\ drive containing the report files. The reports are designed to use a named connection called ReportsConnection which is configured/saved as a shared connection with Alias ReportsConnection in Report Designer.

The default reports connection string is saved in the appsettings.json file.  Upon application startup users select a database connection from a list of saved/remembered connections and the desktop WinForms application saves the user selected ReportsConnection to a configuration file named userSettings.json.  Both appsettings.json and userSettings.json are configured as sources for IConfiguration with reloadOnChange = true.  After a user selects a database connection and the selected connection string is written to userSettings.json, the configuration is reloaded so that the injected IConfiguration from the service container will have the new, user selected value for ReportsConnection.  At this point, IConfiguration has the updated the named ReportsConnection with the desired connection string, which almost always differs from the default one defined in appsettings.json.

However, when loading the reportViewer, the reports unconditionally connect to the server and database defined in the default connection string from appsettings.json, not the user-selected connection string even though the injected IConfiguration has the updated user selected connection string.

When using the Native Blazor report viewer with the latest version of Telerik UI for Blazor (12.0.0), the following exception is thrown:

Unhandled exception rendering component: Object of type 'Telerik.Blazor.Components.TelerikToolBar' does not have a property matching the name 'Adaptive'.

We really need improved default controls in the html5 viewer:
 - DatePickers that allow null values (e.g. from From, To date ranges in reports)
 - Dropdown that isn't a list (for when there are large numbers of options e.g. Customer dropdown)
 - I can't go to page 2 on a mobile - there's no next page, previous page button displayed.
- Pinch zoom freezes on mobile (Samsung galaxy s4). See (advertisement) html5 viewer for a nicer zoom controls. in 1 icon that fits on mobile
 

Telerik Reporting Online Examples have lots of examples of reports, but no examples of how to call these reports!   I'd like to see examples of calling a report from a button on a page, or calling a report by clicking on a button in a radgrid row, and of course passing parameters from said pages or grids.

Add support for the <pre> tag.  This would allow content to be added to the HtmlTextBox without having to worry about encoding it properly.  We use the HtmlTextBox frequently in situations where we want to apply mixed formatting.  

This would help in several scenarios.  One scenario that came up recently was when I wanted to render literal space.  I got around this by replacing every other space with a non-breaking space but the pre tag could have made this much easier.  Other situations involve getting text from the database that could include a < or > symbol which we have also got around making sure we run the text through an HtmlEncode routine.

The Reporting Graph item support now only one data source, unlike RadChartView.
When displaying different collection, we must for the moment put everything in one collection, and group/filter in Graph, because of this limitation.

WPF can display very complex text, like mathematical function, or create intricate image.
Such feature is missing in Reporting.
A function should exist in Reporting to render a WPF control as image in report for such case (using RenderTargetBitmap).

Telerik reporting for asp.net. I suggest to add the "locked" property to the each control that is put on the designer and to whole report likely this done in Crystal Reports from version 7. Sometimes it is hard not touch out suddenly some text box with mouse or keyboard on the designer and not change it size/location.

Thank you very much

Hi, I found a bug, my MVC project is in a subfolder, and for this I have a problem with the ways I use "~" in order to specify the full path to take. 
and then I have a problem ReportViewer 

   @ (this.Html.TelerikReporting () 
           . ReportViewer () 
           . Id ("reportViewer1") 
           . ServiceUrl ("/api/reports/") 
           . TemplateUrl ("/templates/template.html") 
           . ReportSource (typeReportSource) 
            . ViewMode (ViewModes.PRINT_PREVIEW) 
           . ScaleMode (ScaleModes.SPECIFIC) 
           . Scale (1.0) 
           . PersistSession (false))

the fact that in this form 
            . ServiceUrl ("/ api / reports /") 
            . TemplateUrl ("/ themplate / themplate.html") 
operating normally. but it turns out that no subfolders. 
because it is taken still relative.
in when the site is in a sub - I get a 404 error. 
ie ReportViewer script takes a relative path. 
and this is a big problem :) 

Once again, my ASP.NET MVC site is in a subfolder of another ASP.NET project.

get something like: 
my site root url: mysite.com/project1 
and pages:
mysite.com/project1/myreportPage 
mysite.com/project1/api/reports 

When we have a string parameter, and we set the available values, we would like you to have a extra property to set if we have a blank value in the available list, it seems similar with the allow null properties, but sometimes we don't like the null checkbox, it needs more space and we can not translate it.

It would be a great help to have a feature that can copy a whole Column in a crosstab to another one.

It would be very helpful to use the ReportParameters in own User Functions without passing them via an Expression. 

When I select a column in a Crosstab and set a Binding for a Property (for example Visible) it will overwrite all existing Bindings for all Textboxes in that column without any warning. This shouldn't happen. At least there should be a Message that you overwirte existing Bindings and ask if you really want to do that.

If I have my project set to point to a solution folder for the reporting DLLs...and I run the upgrade wizard it changes those references to be instead the installation folder for reporting, so then when I try to deploy (copy) a project...it tanks saying it can't find the DLLs...

If the reference isn't set to a telerik installation folder please don't change it on me

Are there plans to include the Intelligent Mail barcode symbology in the barcode control? We have a client requesting it. 

The date format of the report parameters is related to the culture, but the data source parameter is not.

When opening a data source by the wizard and go through it then save (even without any modification), the provider property will be cleared.

Workaround: Re-set the 'Provider name' again upon closing the wizard, by the properties window.

Product: Report Designer v2014.Q2

When I have a coded dataset (in NeedsDataSource) the designer has no concept of the dataset.  I would like to somewhere define the properties that would be available myself so I can use them from the explorer and in the expression editor...instead of having to keep going back to the codebehind to find the property names.

Please support WebApi 2+, I am stuck using <2 because the Telerik Reporting components are incompatible with the latest ASP.NET WebApi.

Currently the list of marker is limited, but it isn't the case for the WPF RadChartView.
RadChartView permits the display of specifics points (like a vertical line for displaying a limit), but it isn't possible in report.
WPF DataTemplate would surely impossible to reuse in report, but some other custome template should be available like SVG, bitmap, or UTF-8 character (not the best customable solution, but it already increase a lot the possibilities)
