Hello Stano,

Do you need the indeterminate nodes to be treated as checked, or do you need the checked state to be persisted when the child nodes are unchecked? For the first case, the following snippet will get you the IDs of the indeterminate nodes:

var tree = $("#treeview").data("kendoTreeView");
tree.element.find(":checkbox")
    .filter(function() { return this.indeterminate; })
    .map(function() { return tree.dataItem(this).id; });


For the second case, here is a Dojo snippet that shows this.

thx for answer, I need the checked state to be perists when the child nodes are unchecked.
Thanks for example but still is not ok.
 I need checked all parent nodes when I checked QUX in tree. I need combination original demo example with this example what do you sent

When I checked Parent nodes  I need automatically checked Children.
When I checked Child nodes I need automatically checked Parents.
When I have checked all children and i unchecked one of the children a I need the checked state of parent nodes for this children to be persist.

Hello Stano,

This functionality is not supported out of the box. The provided code snippet allows you to gather the indeterminate checkboxes and get the IDs of their data items, so you can process them as necessary.
