    Spark List with TileLayout issues

    thibs73

      Hi all,

       

      I looking to find the solution to this weird issue I am seeing. I have a list with a TileLayout using a custom itemrenderer. The itemrenderer has autoDrawBackground="true" and the list has useVirtualLayout="false".

       

      The issue is that my dataprovider updates on a frequent basis making the list flicker, and even worse when the user is scolling.

       

      Using useVirtualLayout="false" did help, but I do see the list items redraw every time the dataprovider refreshes... This does not happen using the Flex 3 TileList...

       

      Another explanation of what is happening would be that random items in the list disappear and re-appear one by one, or rows at a time, which produces flickering effect.

       

      Is there a way to stop this visual refresh? or has any one seen this before?

       

      Thank-you in advance
