This customization sets the contents of the dropdown list filter.

Filters can be populated in two different ways.

  A. All possible values.

  B. Only values contained in the result set (current query for the table).

Option A or B can be selected in the Display tab of the Properties dialog for the filter.

Option A will populate filter with all the values from the parent table.

Option B will populate filter based on the result set.

For example CustomerID field in Orders table is a foreign key to CustomerID field in Customers table.

If option A is selected then CustomerID filter in Show Orders Table page will be populated from the Customers table.

If option B is selected then the CustomerID filter in Show Orders Table page will be populated will all the values of CustomerID in Orders table(results that would be returned based on the whereClause).

This customization assumes that the filter is populated with All possible values.
