Not rowHeight or columnWidth explicitly. There may be some implicit calls to it, however -- I am setting rowCount and columnCount. Here is the complete file (it's really short) -- I previously only posted the attempted fix written based off of your description. Some of these MXML properties may be redundant, I haven't cleaned up failed attempts to get this to work...
<?xml version="1.0" encoding="utf-8"?> <mx:TileList xmlns:mx="http://www.adobe.com/2006/mxml"; rowCount="{Math.ceil( dataProvider.length/10)}" columnCount="10" itemRenderer="SimpleMXMLRenderer" borderThickness="0" focusThickness="0" paddingBottom="0" paddingTop="0" width="100%"> <mx:Script> <![CDATA[ import mx.controls.Alert; public override function set dataProvider(o: Object): void { if (this.dataProvider) { this.dataProvider.removeEventListener("collectionChange", this.cc); } super.dataProvider = o; this.dataProvider.addEventListener("collectionChange", this.cc); this.callLater(this.cc); } private function cc(event: Event = null): void { this.itemsNeedMeasurement = true; this.invalidateProperties(); } ]]> </mx:Script> </mx:TileList> TIA, Daniel On 5/18/07, Alex Harui <[EMAIL PROTECTED]> wrote:
Is it possible you set explicit rowHeight and columnWidth? commitProperties() should get called followed by makeRowsAndColumn. -Alex ------------------------------ *From:* [email protected] [mailto:[EMAIL PROTECTED] *On Behalf Of *Daniel Grace *Sent:* Friday, May 18, 2007 2:22 PM *To:* [email protected] *Subject:* Re: [flexcoders] TileList itemRenderer resize I added the following code to the TileList: public override function set dataProvider(o: Object): void { if (this.dataProvider) { this.dataProvider.removeEventListener("collectionChange", this.cc); } super.dataProvider = o; this.dataProvider.addEventListener("collectionChange", this.cc); this.callLater(this.cc); } private function cc(event: Event = null): void { this.itemsNeedMeasurement = true; this.invalidateProperties (); } I have added (and since removed, since it was noisy) an alert to my cc function, so I know that it's getting called when my underlying data gets changed... but the individual tiles still aren't resizing. I can see the very top part of the unhidden data in the tiles, but it doesn't expand to see the rest. Am I handling this in the wrong place?

I have been using the same itemRenderer for a while with no problems. I made a change to where one of the UI elements inside of this itemRenderer sets its visible and includeInLayout to false depending on the underlying data. When this happens the height of the itemRenderer should change, but the TileList doesn't seem to realize this. I am assuming that the TileList does a height/width calculation early on and doesn't notice that things are different. I am fine with subclassing, but at this point I don't know where to look for the right functions/events to latch on to to make this work as I expect. BTW, I know that the measurements are based off of the first data element, but because of the way this actual application works all of its itemRenderers will be the same size -- they just need to change sizes at runtime sometimes. TIA, Daniel
