The main thread should be free for the dialog to show. How long does it take to read the 200 records? It should be quite fast.

If it is slow, and you can't optimize it then you need to use SQL.ExecQueryAsync instead.

See my answer above. The first step is to optimize your queries. Reading 2000 records can be a very quick operation if the query uses an index for example.

If it is too slow then you need to use the async method instead.
