RE: [flexcoders] Problem with TileLIst RowCount
After an addChild, a whole validation sequence must happen before the TL is layed out. There is an updateComplete event when finished, or you can force it with validateNow(), but that can be expensive. From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of oneproofdk Sent: Tuesday, November 20, 2007 12:18 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Problem with TileLIst RowCount After adding a tilelist using addchild, I'm trying to resize it's container, a canvas, to fit the tilelist based on the rowcount * rowheight. Strangely it always return rowCount = 2 - even though there is 1 or 3 rows ? How can I force a recount ?? Or is there another way to get the actual size of the content of the tileList. The problem is that I dont know the number of items that the tilelist will display, or how many tilelists there will be. So I need to be able to dynamically resize the container. The tilelist dont have a rowCount property set explicitly, percentheight=100. Hope that someone else has solved this issue. Thanks for your help. Mark
RE: [flexcoders] Problem With TileList...
Well the 12th row is the first one that comes from offscreen right? So the TileList is re-using the cells from the 1st row and redrawing the data for the 12th row. Maybe your setvalue method isnt updating everything that it should in the cell renderer? If you shorten the TileList to only show 5 rows Im guessing that the 1st and the 6th would have the same problem?

All: I am having a major problem with a tilelist.. Here is a simple explanation of what is happening: I have a tilelist that is using a cellrenderer.. I have 14 total rows (or more according to dynamic data) I have room for 11 rows at once... The 1st row and the 12th row are mysteriously LINKED together... though they have different static labels, etc. anything dynamic that I change about them is changed on both of them... Does this make sense? Anyone have had this problem?

RE: [flexcoders] problem with TileList
Duccio,
I think the problem is this line:
img.load=data.thumb;
You are using "load" as if it were a settable property, but
it is actually a method of the the Image class and would therefore be used with
the following syntax:
img.load(data.thumb)
Alternately, you could set the "source" property of the img
object to achieve the same result:
img.source = data.thumb

Re: [flexcoders] problem with TileList
Thanks Kristopher,
iwas tryingwith img.source so i did
that mistake. I have already done the correction but the problem is that i
don't see images yet. I see the items added to TileList and they're selectable
but with no image in it. If i use cellRenderer and dataProvider of
TileList everything's ok.

RE: [flexcoders] problem with TileList
You cant do new Thumbnail() because
its a visual component. You would need to do something like
createChild. However with a TileList the proper way of doing this is the
cellRenderer, so thats what Id do.
