How to bind and display ListBoxItem index in ListBox?

How to create several DropHandlers in WPF using gong?

QUESTION

How to bind and display ListBoxItem index in ListBox?

Asked 2021-Sep-07 at 13:00

I have a .NET 5 project with following Nuget Packages:

HandyControls for UI
Gong-Wpf-DragDrop for Drag and Drop elements in a List

I have a XAML with a ListBoxand a ViewModel with aObservableCollection` of Model.

The ObservableCollection is binded as ItemSource of ListBox

What I want to achieve:

When i Drag and Drop an item in a different position (or Add/Delete), I want the indexes to be refreshed.

Example:

Before Drag/Drop

After Drag/Drop

Actually, i binded the drophandler of gong-wpf-dragdrop and at the end of the drop, i manually refresh every single Index in my list.

there is a way to do it easily? because actually i have to refresh indexes manually.

Summarizing: When i reorder/delete/add items i want Model.Index of every item updated with the correct index position in ListBox.

My Mandate is:

Show index (one based)
Give the possibility to reorder the elements

I tried looking for similar questions but didn't find much that could help me. Thanks in advance :)

You can't implement the interface "again" in the same class but you could bind the DropHandler property to an IDropTarget property of the view model:
