You should be able to just set the property of the objects in your data
provider that the checkboxes are rendering. For example, if your grid
is bound to an array of objects of type MyClass that are stored in
mySourceArray:Array then this would do it.
private function selectAll(selected:Boolean):void
{
for each(var item:MyClass in mySourceArray)
{
item.selected = selected;
}
myGrid.invalidateList();
}
If you need to be very generic and do it for any grid... then you would
need to do something like the following. Note: the code below was
created in this email and has not be compiled, etc. But, it should get
you close :)
private function selectAllInGrid(grid:DataGrid, selected:Boolean,
selectedField:String):void
{
var view:ICollectionView = ICollectionView(grid.dataProvider);
var cursor:IViewCursor = view.createCursor();
while(cursor.afterLast() == false)
{
var obj:Object = cursor.current;
if(obj.hasOwnProperty(selectedField))
{
obj[selectedField] = selected;
}
else
{
trace("Items in the grid do not appear to have property " +
selectedField);
}
}
grid.invalidateList();
}
