    It is announced that the new release Telerik R1 2020 includes a new report viewer control for Blazor applications. 

    2 questions:

    1) Is it possible to see a demo? I couldn't find one on the telerik site.

    2) Will the Web report designer work in Blazor?

    A working example would be nice, open up the CSharp examples from Telerik Reporting R1 2020 and the Blazor does not work, states I need a rest api, so I don't even see the viewer on my Balzor page!

    It would be nice if you could produce fully working examples without the need for us to investigate.

    Hello Eliyahu and Andrew,

    @eliyahu

    1) You can find an example at the installation folder of Telerik Reporting

    C:\Program Files (x86)\Progress\Telerik Reporting <Version>\Examples\CSharp - Blazor HTML5Demo 

    2) Currently, we are experiencing some problems with the integration of our Web Report Designer in Blazor application. As soon as we find a solution, we will post an update.

    @Andrew

    Can you send us screenshots of the errors?

    Hi,

    The Web Report Designer is a Kendo jQuery widget that can be embedded in a Blazor application. Check out this GitHub repo with an example. The example requires the latest Telerik Reporting release R2 2020. Just have in mind the following two known issues:

    • SqlDataSource is throwing errors due to broken APIs in .NET Standard 2.0, this requires special .NET Core 3 build that will be available with the next internal build. Here is the public item on the topic. The item status will be updated when the internal build is available.
    • Using the Web Report Designer with other Kendo controls may result in UI glitches, this is logged and will be fixed with a next release.

    Hello,

    the provided example seems to work only for Blazor server side, right? Are there any plans to use the Web Report Designer in Blazor Web Assembly?

    Regards,

    Daniel

    Hello Daniel,

    The demo project is a Blazor server-side app. Basically, we plan to develop wrappers of the web report designer to support different technologies. Currently, we don't have an example with WebAssembly but you may test it.

    Hello,

    I am developing Blazor based reporting solution.

    While doing so, I have found there is some Blazor support, but not yet full:

    Report viewer

    • Blazor component exists and works (almost)
    • It should be enhanced by using Blazor .NET 5 component js/css isolation to simplify its usage instead of requiring to specify global js/css
    • Using the viewer with more then one Report Service is not possible due to global js/css
    • The viewer does not show embedded report images: there is some ReportController - Engine - Storage problem causing resource not found.

    Report designer

    • I miss Blazor component
    • Should I write one myself to wrap the designer or will You provide one?
    • The same points about js/css isollation applies like for the viewer

    Thank You

    Marek Ištvánek (via JS account)
