The Kendo TreeList has an incorrect colspan value for the headers when the first column is hidden and the file is exported to Excel.

Dojo:

https://dojo.telerik.com/IFuCutaV/4 

The names of the headers are not displayed in the correct positions.

Hi Team,

I would like to request the Kendo UI TreeList to have an optional setting to show aggregate values at the parent row based on the children's aggregates.  

Thank you!

Hello,


We have a grid of tasks and each row has a detail's pane (hierarchy) that shows, when expanded, a tree list of sub-tasks.

If you attempt to delete a tree list node (not the last) it will delete the node correctly, but will trigger the grid's to prompt the user to make sure the item should be deleted or not (which is NOT normal). But when this is shown, it is already too late to Cancel has the tree list has already deleted the item. Users don't understand why they are given a chance to prevent the deletion, but it does not work.

So in short, we want the tree list, when the users deletes a node, to not trigger (i.e. to prevent) the grid's item deletion.

Here is a dojo that shows what happens:

https://dojo.telerik.com/APaXoRuR

Steps to reproduce the bug:
  1. Load the Dojo and open the Network tab of the developer toolbar
  2. Expand one of grid's detail row
  3. Attempt to delete one of the tree list items (except the last item)
  4. Note the dialog popup which is not normally shown for a treelist
  5. Note the Item is already deleted anyway... before the popup is shown...
  6. Click Cancel on the dialog
  7. The item disappears even if you did cancel

Please let me know if you need more information,


Regards,

Eric.

Feeling excited to see Kendo UI treelist is now paginated. It would be great if the same can have virtual scroll.

Add persistSelection property in the Kendo UI TreeList similar to the persistSelection in the Kendo UI Grid:

https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/persistselection

Using the dataBound event is useful for initializing 3rd party widgets within a template (such as bootstrap-toggle) or to use kendo.bind to bind controls to a model. The issue is that when other rows are expanded the internal _render event is triggered which can recreate an existing row which means that the widget reverts back to standard HTML and the binding is lost.

When attempting to use the filter function on a TreeListDataSource, the linked TreeList control reports that are no records to display regardless of what filter is entered.  This includes attempts to clear/reset the filters using an empty object/null and behaves the same regardless of whether serverFiltering is enabled.

The TreeListDataSource object contains the expected records.

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.

Hi Team,

I'd like to request the functionality to drag the column header of a Kendo UI TreeList and dropping it in a grouping section to make the TreeList Groupable. 

Similar to the Kendo UI Grid:
