Hello Sergii,
Currently, the web report designer does not have permissions you can deny or controller methods you can override to disable the creation of new data connections. That said, I believe this is a valid feature request, and I encourage you to submit it in our public feedback portal:
In the meantime, as a potential workaround, you might consider adding a middleware that would intercept the `/api/reportdesigner/connectionspermissions` request to return an empty JSON. By default, it returns the permissions to add shared and embedded connections:
However, returning an empty JSON, or an object with values set to `false` instead of `true`, should also disable the "Build new connections" option:
app.Use(async (context, next) =>
{
if (context.Request.Path.Equals("/api/reportdesigner/connectionspermissions"))
{
context.Response.ContentType = "application/json";
await context.Response.WriteAsync("{}");
return;
}
await next();
});Could you please try this workaround and let me know if it works for you?
If you encounter any issues, I would appreciate it if you could share your observations so we can work together to resolve them.

Thank you very much, Petar - your solution works for me properly and satisfy my requirements.
I have added feature request : WebReportDesigner (Blazor) - new permission to restrict "Build new data connections" and allow to use only "Select from existing data connections"
