namespace Appeon.ApiDoc.IDwTableExamples
{
    public class FilterExample
    {
        private readonly SchoolContext _context;

        public FilterExample(SchoolContext context)
        {
            _context = context;
        }

        public void Example()
        {
            // Creates a new DataStore object.
            var course = new DataStore("d_course", _context);

            // Gets the DataWindow.Table.Filter.
            var filter = course.DwMeta.DataWindow.Table.Filter;

            // A string containing the filter defined in the DataWindow. 
            string expression = filter.Expression;
        }
    }
}
