Hi,

I found a bug when drag&dropping selected tree nodes (extended multi-selection) when the tree is virtualized. Items that never got into view are missing from the Payload Manager Data object. If virtualization is off, works as expected.

Please see modified sample for demonstration. I added 200+ items to League A -> Division A. Select the first item, quickly scroll by dragging vertical scrollbar to the bottom of the list and extend selection to the whole list. Then perform drag and drop. Note, not all items were moved.

Also, the drag visual helper moves and updates very very slowly when dragging hundredths of objects. In our application, we have thousands of objects, which makes it unusable

 

Thank you for a quick fix.

Tomas.

Like RanTabControl

Need this for an application with lots of tabs wich would not fit in the top or bottom template.

Maybe it works with a customizable TabStripTemplate where i can implement e.g. a GridView or something

Like this with a scrollbar (used TabControl PRISM example for this)
