Hello,
There is an issue when RadGridView does not re-evaluate row item if filter property of viewmodel (datacontext of the row) was changed.
For example, RadGridView contains the FilterDescriptor to display all customers where address property is "Address1". It works fine i.e. RadGridView shows only customers where address property equals to "Address1. But then I'll change the address property of viewmodel item from "Address1" to "Address2". And I can see this row on GridView. Expected behavior is RadGridView should filter out customer where address property equals to "Address2".
Is here any workaround?
Thank you,
Yuriy.

Hello,
Currently, RadGridView does not reapply its data operations when a bound item raises PropertyChanged. This is an intended behavior, as forcing SortingGrouping/FIltering is very expensive in terms of performance and it may lead to big bottlenecks in applications that have multiple data updates. However, we have had some client inquiries that suggest adding an alternative mode t hat overrides this behavior. Here is the public feedback item for this request. As a workaround, you can either force collection changed, or edit like stated in the comments:
"By the time being, the data operations can be reapplied either by forcing a CollectionChanged by removing and inserting a given item, or using the approach from the Edit an Item Outside GridView article: http://docs.telerik.com/devtools/wpf/controls/radgridview/managing-data/how-to/edit-item-outside-gridview"
You can also invoke Rebind, but it may be slower than the other alternatives.
