Re: [flexcoders] DataGrid CheckBox itemRenderer select all

[nhid]

Yes, it does set the state based on passed in item data.  I got it to work
now by assigning each of the object into a new arraycollection and reassign
it back to the original.

Thanks Tracy.

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"

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?
