Dynamically change height of TileList

You have to adjust rowCount of Tile List to make height according to data at runtime. In below example if column count is 1 you rowCount="data.length()". Now data can be XML children.length() or array.length or any data length.

[mx:TileList id="_videoList" rowCount="{data.length()}" updateComplete="changeHeight"]

You can also updateComplete if you have column count more than 1.

private function chanegHeight():void{
var rc:int = Math.ceil(data.length() / _videoList.columnCount);
if (_videoList.rowCount!=rc) _videoList.rowCount = rc;
}
