GridView: Assigning a new source collection instance of ExpandObjects to a filtered grid clears its column headers and displays empty rows

The issue is replicated only when a filtering operation is applied. For a grouping and sorting one it is not. In Silverlight when the new source collection is set, the column headers are cleared and empty rows are displayed. In WPF the item is not cleared. The workaround is to clear the FilterDescriptors collection of RadGridView before assigning the new instance of the source collection.

Hello John,

As replied also in the support thread you opened regarding this issue, the fix is available with the latest internal build from 27.02.

All the best,
Stefan

I checked and this seems to be fixed in 2017.1.227. Correct?

Please see the attached simple example solution which can be used to reproduce the bug.

Steps to reproduce:
1) Start the solution.
2) Using mouse, filter the only column "A" selecting only the checkbox for the single entry (which is a random number).
3) Click the "Click me to reproduce bug" button at the top.

The result is as per the attached "Capture.JPG" screenshot. The grid shows unwanted empty rows and loses column headers. The expected result would be to retain column headers and show no rows.
