Describe the bug

When using a collection that supports incremental loading, and the implementation of ISupportIncrementalLoading allows you to specify how many rows are retrieved on each load, then the DataGrid won't continue to load more data after the first set of data is retrieved if the height of the rows it receives is smaller than the available space for cells in the DataGrid.

The only way to get the DataGrid to load more data is to resize the window so that the available cell space is smaller than the total cell height.

Reproducible in sample app?

• This bug can be reproduced in the sample app.

Steps to reproduce

1. Setup a DataGrid with incremental loading from some collection
2. Use an implementation of ISupportIncrementalLoading that allows you to specify the number of rows to be retrieved in the paging operation.
3. Set the page size to a low number
4. Run the application
5. Only the first page will be loaded

Expected behavior

The DataGrid should continue to load data until the CellsHeight is full or there is no more data to load.
