Reports - datasource command parameter is not updating

[Bykiev]

Describe the bug
Table datasource command parameter is not updating programmatically via report parameter

To Reproduce
Steps to reproduce the behavior:

1. Create a report parameter UserId
2. Create a table datasource with command parameter UserId
3. Assign Expression [UserId] to command parameter UserId
4. Set the UserId report parameter value via code:
   report.SetParameterValue("UserId", userId);
5. Get the table datasource:

var connection = report.Dictionary.Connections.First();
var ds = connection.Tables.First();
await ds.InitAsync();
var count = ds.Table.Rows.Count;

Expected behavior
The datasource should be filtered based on UserId parameter value after calling ds.Init(), but the command parameter value is empty.

Of course, I can set command parameter via ds.Parameters, but report parameter should be working too.

Hello!

I am sending you a sample application that demonstrates how to update a report parameter and use an MS SQL connection.

Hi, yes, you're manually setting the dataSource parameter value, but I've a ready report (not creating it via code) and just need to set report parameter and then get the filtered datasource value
