Steps to reproduce:

1. Click filter icon in column

2. Enter invalid value in filter input

3. Press Filter, the value gets underlined, suggesting some kind of error.

4. Click the place marked 1 and then 2.
This time, it seems a message appears about the cause of the error, but it doesn’t fit inside the control.

Hi Team,

We have a large-scale WPF application that uses the Telerik WPF RadGridView across multiple screens. We are experiencing significant memory growth issues. Upon deep analysis of the memory dump, we observed that the RadGridView continuously pushes DispatcherPriority items into the Dispatcher queue. We also noticed an internal timer within the RadGridView that appears to be active even after the control is no longer visible.  We would like to understand how to completely detach and stop this internal timer once the control is removed from the screen, and why the RadGridView keeps pushing DispatcherItem entries into the Dispatcher queue.
