Release 2024 Q3 (Aug)

Bug report

In the TreeList, the row colors are not consistent with other technology divisions, e.g. Angular. With the Classic Silver theme, the rows are not consistent regarding the alternating background colour approach. Additionally, in the Default theme, the rows are not as differentiated as they should be by design.

Note: the issue appears to be related to the k-treelist-group class on the elements in the TreeList.

Workaround: https://dojo.telerik.com/ORIjOcAB/3

Reproduction of the problem

  1. Open the TreeList Overview demo with Classic Silver theme.

Current behavior

The rows' background color are not consistent in regard to alternative background colors.

Expected/desired behavior

The rows' background colors should be consistent with the design.
