Is there a known solution for filtering with TreeView?

[salisbury]

I've noticed this has been requested feature in the past, but am wondering if there's a workaround presently available?  A filtering feature like using a text box to only display parents and nodes which contain the text entered.

Hello,

There is no built-in functionality for filtering the TreeView data as this boils down to processing the data manually based on some filter value (provided in an outside textbox), but you can check out the following documentation how-to article that demonstrates how to achieve the desired functionality:

https://www.telerik.com/kendo-angular-ui-develop/components/treeview/how-to/filtering/

I hope this helps.

is there a expandall function available, so that once a tree is filtered, all of the nodes will expand?

Hi,

There is no built-in expand/collapse all functionality, but we could use the ExpandDirective as demonstrated in the following article from our documentation:

https://www.telerik.com/kendo-angular-ui/components/treeview/expand-state/

Check out the following example that demonstrates how to expand and collapse all nodes programmatically:
