Implement a mouse wheel support for the Horizontal ScrollBars of the control
Design time error occurs when setting MinimizedRowHeight
Add animations for items collection change (add/remove)
Add support for IsSynchronizedWithCurrentItem
Allow setting minimum size of the rows and columns: I don't know at design time how many items there will be in the tileview, so if I set fixed height and width for items I can have the control using only 1/10 of the available space, but if I don't set them I can have many too-small items which content cannot be properly displayed. I need a minsize for the items so if I have few items they have a variable size and if they are a lot they use the scrollbars.
If minimized items are placed top, the horizontal scroll bar should be top as well and so on.
Both events must be raised only once per item. Also, the event arguments of each event must contain a reference to the item that begins/ends its layout change.
When an item is maximized, the other items should remain in restored state.
"Move the "Fluid" threshold properties to the TileView level. It seems rediculous that these need to be specified in every Item (sure, I know there is templating, but this would also reduce your code/logic for calculating the areas of items). If this can be done with attached properties it might be more intuitive and less obtrusive on the control (ex. <RadTileView RadFluidContentControl.LargeToNormalThreshold="200" />)."
Provide close functionality out-of-the-box.
TileView: Allow users to see the TileViewItem OldState property
Allow users to specify custom panel for the MinimizedItems. The specific request is the minimized items to be rendered in two columns.
Allow the users to resize the MinimizedColumnWidth with a GridSplitter.
Visualize drop zone (dashed line in iGoogle)
Reorder underlying collection as tiles change position.
Allow users to resize the tiles. Possibly by dragging a left-mouse cursor on the edges of the tiles. This will give flexiblity beyond the 3 fixed size of minimized, maximized, and restored.
