Gino: If you use the relationships set into the data properties for the grid, you don't need to explicitly set filters. I use an index for the child table that has the parent ID + the fields I want to sort on. For example, if I'm showing a list of names for each company, I index the name table on CompanyID + upper(last+first). Names neatly arranged.
