Does your itemRenderer override the set data() function and set the state of the checkbox based on the passed in item data?

However, after I sort any of the columns in the datagrid, clicking Check All will miss 1 or more boxes, then when I click on Uncheck All, the currently checked boxes unchecks and the missed boxes become checked. Any ideas? Thanks. ************* <mx:DataGridColumn dataField="Check" itemRenderer="CheckRenderer" headerText="Option "> private function checkAll():void { var obj:Object = new Object(); for (var i:int = 0; i < dg.dataProvider.length; i++) { obj= dg.dataProvider[i]; obj.Check = true; // = false for uncheckAll() dg.dataProvider.itemUpdated(obj); } } On 10/17/06, Tommy Mestdagh <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: > I also need to be able to check which CheckBoxs are selected This is wath you are looking for. I have a grid with a column named "deleted" . By clicking the checkbox you mark the item to delete (webmail style) This method pushes all marked items from the grid into a new array todelete. all items in the array todelete will be deleted later on. Good luck .
