Drag and Drop with AutoBringIntoView

[Audrey]

Hi,

I used a Listbox with a WrapPanel in an ItemsPanelTemplate, like this :

<ListBox x:Name="ProgrammingBox" SelectionMode="Extended">
      <ListBox.ItemsPanel>
               <ItemsPanelTemplate>
                    <toolkit:WrapPanel  />
              </ItemsPanelTemplate>
       </ListBox.ItemsPanel>
</ListBox>

I used the RadDragAndDropManager.
I have a ListBox with an average of 150-200 items, and I want to drag and drop items in my ListBox to reorder them. I want to move an item and that the scrollbar move automaticaly itself. I use the AutoBringIntoView property but it don't work in my case.
This is my code-behind : 

RadDragAndDropManager.AddDropQueryHandler(ProgrammingBox, new EventHandler<DragDropQueryEventArgs>(OnDropQuery));
RadDragAndDropManager.AddDragQueryHandler(ProgrammingBox, new EventHandler<DragDropQueryEventArgs>(OnDragQuery));
RadDragAndDropManager.AddDropInfoHandler(ProgrammingBox, new EventHandler<DragDropEventArgs>(OnDropInfo));
RadDragAndDropManager.AddDragInfoHandler(ProgrammingBox, new EventHandler<DragDropEventArgs>(OnDragInfo));

RadDragAndDropManager.AutoBringIntoView = true;

Hi Audrey,

Please, check the attached example demonstrating this behavior. Note that in Q3 release there were some issues with this functionality, so please use our Q3 SP1.
