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
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.
lets set the page size of treelistview and provide the endless scrolling feature along with the paging on the grid. When the user will scroll up/down the respective page from where the latest data being fetched should be selected and user should be given the flexibility to move to next page. This way user can move to the desired data (say last) using paging and enjoy the endless scrolling too.
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
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))
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.
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.
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.
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.
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.
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.
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
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.
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):
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.
