RE: [flexcoders] Re: AUTO DELETE ITEMS IN DATAGRID
What are you expecting this to do:
datagrid2.selectedIndex.AutoB()
AutoB() is not a method of datagrid2.selectedIndex.

Yeah if it's saying undefined method, you're going to want to make sure
you are calling the right function on the right object. From the code below it
looks like your DataGrid does not have an id, so try giving your datagrid an
id, then call removeItemAt on the dataProvider that goes with that id.
publicfunction AutoB():void {
if (myDataGrid.dataProvider.length
= 2)
{
myDataGrid.dataProvider.removeItemAt(0);
}
}
mx:DataGrid id=myDataGriddataChange=AutoB()

Re: [flexcoders] Re: AUTO DELETE ITEMS IN DATAGRID
Ahh, I see. I think what you need to do is listen for the dataChange
event on the data grid you want to keep at 5 items. In the event
handler, count the rows in the data provider. If it's more then 5,
then do your removeItemAt(0);
Here's more info on dataChange if you are unfamiliar with it:
