you can do a for each to do this
var itemToRemove:int = 2;
var newArray:ArrayCollection = new ArrayCollection();
for each(var a:Object in gridData) {
if(a.grid != gridToRemove){
newArrayCol.addItem(a);
}
}
gridData = newArray;
if you want to get the index of your item you can do something like this...
var index:int = 0;
for each(var a:Object in gridData) {
if(a.grid == gridToRemove){
index = gridData.indexOf(a);
}
}
