Expanding or Collapsing Groups While New Items are Added Cause the RadTimeline to Display No Items
Environment
Product Version | 2019.1.220 |
Product | RadTimeline for WPF |
Description
Expanding or collapsing groups, while new items are being added, can cause the RadTimeline control to display no items at all.
Workaround
Disable the collapse/expand animations. You can do this via an implicit style that targets the TimelineItemGroupControl, and set the AnimationManager.AnimationSelector attached property to null.
<Window.Resources>
<Style TargetType="telerik:TimelineItemGroupControl">
<Setter Property="telerik:AnimationManager.AnimationSelector" Value="{x:Null}" />
</Style>
</Window.Resources>
