As discussed on the forum (http://www.telerik.com/forums/virtualization-for-treelist) please improve the rendering/scrolling/expanding/collapsing performance of TreeLists with many expanded rows.

Grids support virtualization and work well with hundreds of thousands of rows (http://demos.telerik.com/kendo-ui/grid/virtualization-local-data). Perhaps virtualization can be added to TreeLists to achieve similar results?

Much like how the Grid has column grouping, it would be nice if the TreeList had this as well.

I would like to use drag and drop on treeList to reorder rows (with same parent) like on treeView or at least to have same events (drag, dragstart, dragend, drop), where I'll be able to change behaviour.

Great work on this control boys.... I reckon it needs Filter Row, Multiple Column Sort, Paging to make it consistent with the grid.

Request to add Batch Editing feature for Kendo Tree List

Please, add for TreeList support of setOptions and getOptions methods.

Support inline editing in Treelist

apply a row template to the TreeList !

Hi.

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

Thank you.

Is there any support for checkbox columns in the treelist to behave the same way as the kendoTreeView checkboxes? 

(ie, checking or unchecking parent should check/uncheck all children? and checking or unchecking children should update parent check state (possible indeterminate states))

The TreeList needs a DetailRow with DetailTemplate just like the Grid has.  The Grid does not support Hierarchial data that has more than one level of depth but the TreeList does and yet has no Detail Row.  Please add a Detail Row.

Please add keyboard navigation to the TreeList, just like the same feature in the Grid

Would like this option just like the regular grid has:

Hi

Would like to request for Treelist with Server side paging and load childs on expand parent. Thank you.

It would be nice if there was an option to not retotal the entire table if you expand a level in the treelist.  We use the table for lazy loads, so each level already has the total, we're just getting the details.

Kendo tree list does not support column resize for touch devices. It would be very helpful if this can be considered since our application supports touch devices and without column resizing feature in kendo tree list columns it is very difficult to read the text in tablets, etc

It would be nice to have an option to repeat the headers within each level of the tree list.  This would allow a user to sort within the level.  We have large datasets with lazy loads.  We could use the grid control and embed a table within the grouping but users like how the columns line up in the tree list.

It would be nice if the footer of the kendo treelist didn't disappear when the table is in scroll mode.  I think it would be more beneficial if the footer were stagnant similar to the kendo grid.
