Drag & Drop works only once

[Stephan Schrade]

Hi support,
as I wrote earlier in this forum (https://www.syncfusion.com/forums/182891/reorder-items-not-available ), I was quiet happy to have drag&drop available in SFListView.

But now I have the problem, that after I made drag&drop, the function does not work any more.
This happens regardless of refreshing the contents of my underlying collection programmatically within the ItemDragging event or if I use "UpdateSource="True"" within the DrapDropController.

I think this worked well with the first version of drag&drop in the listview (but now I'm on version 22.2.7).

Regards,
Stephan

Hi Stephan,

We have analyzed your query and attempted to reproduce the reported issue on our end. However, we were unable to replicate the problem as described. It seems that we do not fully understand your query. Could you please provide the following details

1. SfListView initializing code snippets
2. Underlying collection related codes 
3. Running platform (Model and OS)

For your reference, we have attached a sample where we created a DragDropController and set UpdateSource to True. If we missed any customizations, please feel free to modify and send it back to us so that we can validate it.

Regards,

Hi Diwakar,

many thanks for your example.

But this also does not work.

I can only drag and drop once.

After that I can only select a row but nothing else happens.

My environment:
macOS Ventura 13.5
Visual Studio 17.6.2
Simulator: iPhone 14 Pro (but does also not work on a real device)

Regards,
Stephan

Addition:
I just noticed:

If I wait for a longer time (10 minutes or so) I can drag&drop again.
Very strange.

Stephan,

We have analyzed your query and it appears that this break issue is occurring due to one of the dependency packages, Syncfusion.Maui.Core, of SfListView. So we are checking this with respective team and provide you with further details on or before August 14, 2023.
