Welcome to the WPF feedback portal. We’re happy you’re here! If you have feedback on how to improve the WPF, we’d love to hear it!>
Thanks for joining our community and helping improve Syncfusion products!
The Syncfusion WPF Treemap does NOT animate properly during drilldown and drill up.
Syncfusion's Flutter Treemap DOES animate properly and should be used as an example when updating this important control.
You always want the animation to start from the rectangle clicked on which should expand to reveal the subtreemap it contains. When drilling back up, the subtreemap should collapse back into the original containing rectangle at the higher level.
Thank you,
Mark
