Hello

I have a dropdowntree that is updated using a treelist.

I wish when I check a line in my treelist check the corresponding value in the dropdowntree.
But also uncheck the old value.

I use this for

dropdowntree.get_entries().clear()

This method works the first time but if I check a value a second time it no longer works.

I have that :
Dropdowntree.get_entries().count() = 0

I find the solution

var dropTree = document.getElementById('<%= RadDropDownTree.ClientID %>');
dropTree.control.get_entries().clear();
