I'm trying to build a custom report generator using the web report designer. all the data sources will be web service data sources.

now I need to impose restrictions for using the already created data sources/reports based on the logged-in user privileges.

1. How can I restrict some users from using certain Shared Data sources or accessing specific reports that are created based on their user rights? 

2. how can I get a list of all the web service data sources created programmatically?

While rendering report got Error like this Error loading the report viewer's templates. (trvTemplateUrl = 'https://abcdf.com/api/reports/resources/templates/telerikReportViewerTemplate-16.0.22.225.html/').  when i try this same telerik reporting from other domain it's working only this domain it gave this error. and network it shows like CORS error. we don't know where to allow all the domain address.       In Asp.net we have this config to enable CORS          

  services.AddCors(c =>
            {
                c.AddPolicy("AllowOrigin", options => options.AllowAnyOrigin().AllowAnyHeader().WithExposedHeaders("X-total-count")); 
                c.AddPolicy("ReportingRestPolicy", corsOptions => corsOptions.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader());
            });



            app.UseCors("ReportingRestPolicy");

Hi,

I am using Standalone Telerik Report Designer and trying to input a data into text box highlighted with red square (refer the attachment). I was inserting the textbox directly (look blue arrow) without inserting a table first as pageHeaderSection cannot be inserted with table. However, I found that No data source shown in the data explorer. Can someone guide me on how to input data into the textbox directly without inserting table first?

Thank you.
