Selected Cells and Sorting/Grouping in RadGridView

[Andree]

Hi,

it took me a while to find out the actual behavior of the GridView, but I think I got and now and would just like to point out a misleading example and ask if I've misunderstood something.

When attaching to the RadGridView.SelectedCellsChanged-event, I get the following behavior:

1.  When a complete row was selected and the grid is sorted/grouped, I receive a SelectedCellsChanged-event with the newly added cells (all cells of the row). However, the GridViewSelectedCellsChangedEventArgs do not contain the removed cells. Is this by design because the removed GridViewCellInfo-instances are no longer part of the updated grid?

2.  When only single cells were selected and the grid is sorted/grouped, the selection of these cells seem to be cleared. However, I do not receive a SelectedCellsChanged-event. This is okay for me, as I can still listen to

• the RadGridView.Sorted-event 
• the RadGridView.Grouped-event

and clean up my ViewModel-CellSelection there. But this leads to the misleading example "Grid View - Selection" in the WPF Controls Examples suite. Here, the SelectedCellsBindingBehavior.cs only listens to the SelectedCellsChanged-event, which results in cells still being listed in the "Selected cells:"-Listbox of the example after a sorting operation, although they are no longer selected.

 

Greetings,

Andree

Hello, Andree,

I can confirm that I was able to replicate the behavior you described and it is not very intuitive even though it seems to be the case by design. I will discuss this with our development team and update you as soon as I have more information on the matter. We will also consider updating the example which you referenced.

Thank you for your patience.

We can confirm that this is a bug at our end and I have thus logged the following bug report in our feedback portal regarding it on your behalf. As a thank you for bringing this to our attention, I've awarded you with some Telerik points.

Please follow the feedback item to get notified about any changes in its status. I do hope you can achieve the desired result by handling the Sorted and Grouped events for the time being.

Hi! Thanks for the update and the created bug. Yeah, we can work around this with the events mentioned above. Adding this to the SelectedCellsChanged-event would be appreciated of course, as it was a small pitfall at least for me.

Greeting,

Andree
