Hi,

 

  We are facing a notable poor performance in tree view when loading about 1500 tree nodes with custom template and it is taking approximately 32 Seconds to load it. You have already provided load more option to virtualize data but this is not so user friendly and suggested listview which has virtualization also not good fit to replace treeview.  I wonder how this virtual scroll is missed in tree view!!. It is very important component to our project If you could provide this feature will be great.

 

Thanks& regards,

1. Start using the Kendo Tree View in Angular.

2. Load a large dataset for the Kendo Tree View, observe the time taken to render the Tree View.

3. The timing will increase if the dataset keeps on increasing.

4. Suggest some ways to reduce or optimize it.

I am using Kendo TreeView to show the data in a hierarchal manner, the icons that Kendo gives by default can be in expanded/collapsed state. I want to show a border/line with the icon to clearly highlight the hierarchy of the nodes. 

Hello,

Do You have plans, to provide extended 'desktop-like' multiselection of nodes with ctrl/meta or shift key pressed?

Hi,

 

 The tree view enables us to drag and drop one item at a time. we have a scenario where i want to drag and drop multiple items. tree view also enables multiple selection of items but not supporting drag and drop of multiple items. Could you please provide some solution to dag and drop multiple items
