Hello Shlomy,
When the
RadTileView is databound it orders its items accordingly to the order of the items in its source collection.
Also by design the control reorders its items whenever its data source changes. Therefore when you try to replace an item ( I suppose by deleting the old one and adding a new one), the
RadTileView reorders its items immediately after the old item is removed thus filling the available positions and when the new item is inserted in its place, it cannot be placed on the position of the removed item since that position is already filled. This is why the newly added items are always displayed as last.
Therefore in order to replace a tile with a new one, you will have to use a temporary collection to hold the source collection. Then you can apply the changes to that temp collection and then update the source collection. I attached a sample project illustrating this approach.
Also, there is a PITS item associated with this issue and you can vote for it
here thus increasing its priority.
