Filter RadTreeView Nodes Client side

[Mark]

Hi,
I have a radtreeview control on my aspx page. The treeview control is populated from a dataset on selectedindex_change event of a combobox control through asynchrounous postback.

I have a text box in which the user enters a string, based on the string entered the nodes which contain the string in their text must only be displayed. eg:- if(treeview.node[i].text.contains(textbox.text))
                            {
                                display node........
                            }
                            else
                            {
                                node.visible=false;
                            }
To achieve this I have a textbox onkeypress event. But whenever i try "treeview.AllNodes.length" in my javascript it gives me null.
Kindly guide me through.

Thanks.

Hello Mark,

Please try using the get_count() function, for example tree.get_nodes().get_count(). For more details you can refer to this help article.
