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:
The functionality of treelist with drag&drop without autosync and without batch saving, at the end of the drop the change is not saved.
There is available a hack in the forum
For me this is a bug because I would expect for the change with drop to be automatically saved but it seems that for your support it is not. I understand that all the other changes are saved by the user with a button but the drag&drop does not have a button for it.
So if you do not want to implement this at least add a warning in the drag&drop demos page about this and provide the hack from the forum link or something so that others can know that they have to apply the hack in order for the drag&drop change to be automatically saved.
We use the treelist to create our commercial offers. Each offer can have a node with lots of children at the same level.
The user should have the possibility to add a node at the same level of the selected item.
Now it is only possible to add a parent or a child in the first position and after that sorting the treelist. It is very confusing if the node list is quite long.
It will be nice to have two methods like inserAfter(selectedRow) or inserBefore(selectedRow) as for example the methods you have for the treenode
column.values like feature in kendoGrid would be ideal in kendoTreeList.
if you look at this dojo (http://dojo.telerik.com/oSOloLuR) the attributes work for kendoGrid. If you change to a kendoTreeList, the conditional attributes do not work. Is there a different way to change the attribute? I tried in the template, but can't set the background-color style in the temple.
Code from dojo with kendoGrid changed to kendoTreeList:
The TreeList control doesn't allow for a fixed row of aggregates at the bottom of the control. I would like to have the option to enable a row of "Grand Total" aggregates that are aggregates of the whole data set. This row would be fixed at the bottom of the control and wouldn't be scrollable. This is functionality that the Kendo Grid has that isn't available in the Kendo TreeList.
Changes to edit cells are lost when clicking the next cell or other rows in the TreeList.
Dojo Example adapted from TreeList InCell Editing demo (also attached):
Hi, it would be really helpful to have an event like beforeEdit (present in the Grid) in order to eventually cancel the edit event for certain rows. For example: I want the user to be able to edit only nodes without children and, as today, i cannot cancel the edit event. Tanks
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. Also see https://www.telerik.com/forums/toolbar-template-59985d731e9b
Some times, when we expand children, we want to see the grand children on top then children and then the parent. in my case it has to do with the date they were created and I want to show the newest first.
it would be really help full to get same footerTemplate as kendo grid has where you can get the column info plus you can get the current dataItem.
In the treelist, I would appreciate to have a loading component when the user performs actions (sort, filter). It is very disturbing, as the user doesn't know that the tree list is loading and he has to wait. Moreover this feature already exists for flat grids.
