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?
Great work on this control boys.... I reckon it needs Filter Row, Multiple Column Sort, Paging to make it consistent with the grid. Regards, Scotty
When you add keybord navigation to the TreeList, alongside with the ability to drag and drop TreeList rows, keyboard events won't fire. http://jsfiddle.net/ahz94f1j/2/ It looks more like an simple oversight, but we asked suppport and they responded that we should make a suggestion here.
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
In the TreeList control when I Freeze first column and apply multi column header in some other column, then setting the filterable property for a column after multi column header is applied to some other column instead of the column on which it is set.
You can find a working sample here.
In this example note that I have set the filterable property false for field "Phone" but its effect is applied on "Position" field and its filters are hidden. Similarly if you apply filterable: false on "Extention" field then the filter on "Address" field will be gone.
Kindly provide a solution for this problem, also let me know if a work around exists for this issue.
