Hello all, I have a grid list in which there is a column 'Document Number'. The values of this column are returned by display method and are string values with comma separated like 'DOC_NUM_001,DOC_NUM_002'. Since the default filtration is not working on this field as the field has method retuned values. I need to apply sorting on this field and I also don't want to disturb the default sorting behavior on the other fields. Should I have to execute query on data source but don't know when that query should be executed as it will be done by user will. Hopes for suggestion
