Prevent Removal of Items on Drag and Drop

[John]

Is there a setting within SFListBox to prevent items from being deleted from a list when dragging and dropping.  For Example, I have items in ListA and drag items to ListB but I don't want the items removed from ListA.  To be clear, items in list A to be copied to List B when dragging.

Hi John, 

 

We can achieve your requirement by using the Dropped event as shown in the code below. 

 

[Index.razor]:  

<ListBoxEvents TItem="CountryCode" TValue="string[]" Dropped="Dropped"></ListBoxEvents> 

public async Task Dropped(DragEventArgs<CountryCode> args) 

{ 

    await ListObj.AddItems(args.Items, (int)args.PreviousIndex); 

}
