Yes, that's right. Now, you have to specify column and row count.
You don't have to do this in wrap panel.
Let's assume that you would be able to provide something like MaxColWidth and MaxRowHeight.
The purpose of that is to be able to have undefined number of items. What's more items would be dragged.
For example:
Let's say you have now TileViewControl with 4 columns but with only 2 items.
So it looks like that:
```
------------------------------------------------------
== Item 1 == == Item 2 ==
| | | |
| | | |
| | | |
| | | |
-------------- ------------------------
------------------------------------------------------
```
So you have "2 cols empty".
Now, I would like the user to be able to drag the item into the empty colum, like this:
```
------------------------------------------------------
== Item 1 == == Item 2 ==
| | | |
| | | |
| | | |
| | | |
-------------- ------------------------
------------------------------------------------------
```
In current version user is not able to do that. He can only swap item1 and item2.
