How to specify default filtering when showing data after page loading

[kva]

I have grid, which has a boolean column, I want after page loading, to show only records with true value of the boolean column. I'm using row filtering, and I also want to show filter controls for this column activated on true value. I turned off server operations.

I found it, in datasource we need to specify:

.Filter(c => c.Add(e => e.IsActive).IsEqualTo(true))
