How do I update the datagrid.selectedIndex after a column sort? If you select a row in a datagrid and then sort a column that changes the order, then the selectedIndex doesn't get updated with the new value. I tried invalidateList(), but didn't help.
Here's an example: First select an item, then sort a column that rearranges the rows and notice that the selectedIndex didn't update. <?xml version="1.0"?> <!-- DataGrid control example. --> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";> <mx:XMLList id="employees"> <employee> <name>Christina Coenraets</name> <phone>555-219-2270</phone> <email>[email protected]</email> <active>true</active> </employee> <employee> <name>Joanne Wall</name> <phone>555-219-2012</phone> <email>[email protected]</email> <active>true</active> </employee> <employee> <name>Maurice Smith</name> <phone>555-219-2012</phone> <email>[email protected]</email> <active>false</active> </employee> <employee> <name>Mary Jones</name> <phone>555-219-2000</phone> <email>[email protected]</email> <active>true</active> </employee> </mx:XMLList> <mx:Panel title="DataGrid Control Example" height="100%" width="100%" paddingTop="10" paddingLeft="10" paddingRight="10"> <mx:Label width="100%" color="blue" text="Select a row in the DataGrid control."/> <mx:DataGrid id="dg" width="100%" height="100%" rowCount="5" dataProvider="{employees}"> <mx:columns> <mx:DataGridColumn dataField="name" headerText="Name"/> <mx:DataGridColumn dataField="phone" headerText="Phone"/> <mx:DataGridColumn dataField="email" headerText="Email"/> </mx:columns> </mx:DataGrid> <mx:Form width="100%" height="100%"> <mx:FormItem label="selectedIndex"> <mx:Label text="{dg.selectedIndex}"/> </mx:FormItem> <mx:FormItem label="Name"> <mx:Label text="{dg.selectedItem.name}"/> </mx:FormItem> <mx:FormItem label="Email"> <mx:Label text="{dg.selectedItem.email}"/> </mx:FormItem> <mx:FormItem label="Phone"> <mx:Label text="{dg.selectedItem.phone}"/> </mx:FormItem> </mx:Form> </mx:Panel> </mx:Application>
