Hi all, I have code similiar to this, where it checks all the checkboxes when I click on a button Check All and unchecks all when I click on Uncheck All.
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);
}
}

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 .

private function collectForDelete():Array{
var todelete:Array = new Array();
var obj:Object = new Object();
for (var i:Number =0 ; i < table_grids.datagrid.dataProvider.length ; i
++){
obj = table_grids.datagrid.dataProvider[i];
if (obj.deleted) {
var record:RecordDTO = new RecordDTO();
record.setColumns(obj);
todelete.push( record );
}
}
return todelete;
}

I have a DataGrid and the first column's item renderer is mx.controls.
CheckBox. I would like to be able to have a select all button that sets
all of the CheckBox selected = true. I also need to be able to check
which CheckBoxs are selected. Any suggestions?
