Body
I have a datagrid with an xmlListCollection bound to it: <pre><code><mx:DataGrid id="dgCompetente" includeIn="Competente" x="10" y="66" width="547" height="468" change="dgCompetente_changeHandler(event)" dataProvider="{colCompetente}" editable="false"> <mx:columns> <mx:DataGridColumn headerText="ID Competenţă" dataField="idCompetenta"/> <mx:DataGridColumn headerText="Denumire Competenţă" dataField="denCompetenta"/> <mx:DataGridColumn headerText="Competenţă Superioară" dataField="idCompSuperioara" labelFunction="labelFunctionCompetentaSuperioara"/> </mx:columns> </mx:DataGrid> </code></pre> and a button to delete the currently selected item in the datagrid, which has this function assigned to the click event: <pre><code><s:Button id="btnDeleteCompetenta" includeIn="Competente" x="813" y="65" label="Stergere" click="deleteCompetenta()"/> private function deleteCompetenta():void { try { var position:int = dgCompetente.selectedIndex; if (position >= 0) { colCompetente.removeItemAt(position); dgCompetente.selectedIndex = position; } clearEdit(fieldsCompetente); saveCompetente(); } catch (error:Error) { errorHandler.defaultErrorHandler(error); } } </code></pre> I want the selectedIndex to remain the same. So, if I delete item 2, the next in the list should be selected. The problem is that if I delete item 2, item 3 will be selected and I have no idea why. Can someone tell me what I'm missing? Thank you!

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
