It will be nice to have examples and documentation to perform manual operations (like sorting, filtering, grouping, paging) in the TreeList.

Hello Telerik Team,

I am currently using your TreeList Component with the CheckboxColumnComponent.

Unfortunately it is not possible to configure the CheckboxColumnComponent to show the indeterminate state of items in the checkboxes.

On further research I discovered, that your TreeView Component supports this feature.

The following Screenshot has the TreeView Component  showing the indeterminate state of the Item "Furniture".

(Screenshot was taken from one of your own examples here: https://www.telerik.com/kendo-angular-ui/components/treeview/checkboxes/#toc-setup)

Comparing it with a TreeList that has checkboxes in the next screenshot, you can see that the parentitem with an indeterminate state, in this case the item with the name "examples", just shows  an empty checkbox.

 (Screenshot was taken from one of your own examples here: https://www.telerik.com/kendo-angular-ui/components/treelist/selection/#toc-checkbox-selection-of-child-rows)

Sadly i am not able to switch to the TreeView at this point in time, due to some conflicts this would create concerning my requirements for apearance and features of the application. Thats why i have the following question for you:

Would you consider adding this feature of showing indeterminate states to the CheckboxColumnComponent that is used in the TreeList Component in the future? Or do you have any advice on how to achieve this look similar to checkboxes from the TreeView in the TreeList?

Thank you in advance and best regards

Provide sticky column feature, the same as in Grid:

https://www.telerik.com/kendo-angular-ui/components/grid/columns/sticky/

Autosize on treelist with locked columns does not work

When the width of the grid exceeds the column lengths, you would expect autosize to expand and fill the rest of the space evenly.

Similar to https://github.com/telerik/kendo-angular/issues/3248

The drag selection is enabled immediately after dragging the cursor a little (1-2px). This causes issues when a row is expanded/collapsed first then clicking the checkbox as sometimes, the cursor is dragged in the checkbox. Then drag selection resets the previously selected rows. Here is a screencast of the issue:

https://screenrec.com/share/y6pPGWjUZH

1. Expand a row
2. Click and drag the cursor in the checkbox (1-2px)

https://stackblitz.com/edit/angular-qnaphv-2nszye

The drag selection should not be enabled.

The Grid has a logic for enabling the drag selection after N-pixels of dragging. Could be reused in TreeList as well.

Hi,

Please add a multiSortKey option to the TreeList component as well. There is currently such option only for the Grid:

thanks

Hi Kendo Team,

Could you add a checkboxOnly functionality to the TreeList component selection SelectableSettings => checkboxOnly setting similar to the Grid component SelectableSettings:

https://www.telerik.com/kendo-angular-ui/components/grid/api/SelectableSettings/#toc-checkboxonly

Thank you.

Please add a feature that allows to create the footer template only for specific nodes. 

Thanks

How can I reload the treeList without expanding the children, I only want to show parents (the first level nodes)?

Is there an example or documentation to manipulate a TreeList I want to add several rows in the TreeList and then save all the changes made in the component. Examples (AddChild and AddSibling). How could I handle that scenario where everything I do in the TreeList is stored temporarily until confirmed with a save button.

Is there some documentation or example of how to sort on a TreeList of the entire hierarchy when the hierarchy is created on demand. That is, I want the sort to order the parent node along with its children.

Provide an option to set a default value for the parentId field just like the defaultValue of the Kendo UI for jQuery TreeList:

Thank you

Please provide a built-in drag-and-drop functionality for the TreeList component that will allow the end user to reorder items as necessary.

Please provide keyboard navigation as in the jQuery version: https://demos.telerik.com/kendo-ui/treelist/keyboard-navigation

Please provide built-in expandRow() and collapseRow() methods.

Thank you
