Hello all, I have a question about our favorite topic
-- datagrids!
This is with Flex 2.
Let's say that I have 2 identical datagrids, both with the same
dataprovider. What I want to accomplish is when a user selects
something in datagrid1, I want that same item to be selected in
datagrid2, INCLUDING scrolling down to where that item exists.
Here's the code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Script>
<![CDATA[
import mx.events.ListEvent;
public function keepSelected(event:ListEvent):void {
if (grid1.selectedIndex >= 0) {
var i:int, len:int;
len = grid2.dataProvider.length;
for (i=0; i<len; i++) {
if (grid2.dataProvider[i].oid ==
grid1.selectedItem.oid) {
grid2.selectedIndex = i;
// -- [TODO --
// Figure out how to get the
verticalScrollPosition set correctly.
break;
}
}
}
}

<mx:Array id="myData">
<mx:Object oid="1" region="North"
newsales="50" usedsales="25"

Any ideas? I just want to scroll the user down to the place where the
selectedItem is displayed. Is this even possible?
Thanks,
Jacob
