Flex Datagrid persistant Caseless Sorting |
|
|
I've been working on a project with multiple data grids with multiple columns. The users requested two things: when they get the refreshed list from the server they would like the datagrid to keep the sort that was on it prior, they also want the sort to be case insensative. Below is the actionscript class I created to do just this. I haven't done much testing, but if I make some major updates I'll update the code! I also plan to have it hold the last selected item and reselect it after the reload of data as well!
I just extended datagrid, and this is Flex 3.0, I am guessing it will work the same with gumbo, and around the same way with advanced data grid.
package classes.extendedComponents { import mx.collections.Sort; import mx.collections.SortField; import mx.controls.Alert; import mx.controls.DataGrid; import mx.controls.dataGridClasses.DataGridColumn; import mx.events.DataGridEvent; import mx.utils.ObjectUtil;
public class InsensativeSortHoldingDataGrid extends DataGrid { public function InsensativeSortHoldingDataGrid() { super(); } override public function set dataProvider(value:Object):void { var temp_sort:Sort = null if ( (dataProvider != null) && (dataProvider.toString() != "") ){ if (dataProvider.sort != null) { temp_sort = dataProvider.sort //Alert.show(sort.toString()) } } for each (var dgc:DataGridColumn in this.columns){ dgc.sortCompareFunction = doCaselessSortForField(dgc.dataField) } super.dataProvider = value if (temp_sort != null){ super.dataProvider.sort = temp_sort super.dataProvider.refresh() } } public function doCaselessSortForField(field:String):Function { return function(obj1:Object, obj2:Object):int { return ObjectUtil.stringCompare(obj1[field],obj2[field],true); } } } |
