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.

Hi Team,

I would like to request when paging in the TreeList to include the prior parent node in the new page.  For example, if there is a parent node that has 30 child nodes, and the pageSize is 15, show the parent node on page 1 and 2.  

Thanks!

Hi.

I would like the ability to specify a template for the toolbar in a TreeList, much like the ability in the Grid.

Bug report

TreeList shows wrong total and paging when we expand or collapse a row after filtering.

Reproduction of the problem

1. Go to TreeList demo link - https://demos.telerik.com/kendo-ui/treelist/index
2. On "Position" column apply filter with value "VP, Engineering"

3. After filtering only 4 rows will be visible, and the number of rows at the bottom of grid shows "1 - 4 of 4 items".
4. Now collapse the second row. Notice that the total at the grid bottom changes to "1 - 15 of 4 items" which is wrong.


Expected/desired behavior

The shown message within the pager has to be "1 - 4 of 4 items" instead of "1 - 15 of 4 items".

Kendo UI Treelist currently only supports pagination using pager. This is confusing for user when the hierarchy is spread across multiple pages. On the other hand if Treelist supports Virtual Scrolling (client side paging) like we see in Grid, the user will get more clarity of the hierarchical structure.
