Get serialized data from tree view?

[Ingo]

Is it possible to get serialized data from the tree view - json array or something?

Thank you for your help

Hello Ingo,

If you want to access the data that has been passed when the treeview was initialized, you can use the get it from the options.dataSource field:

var data = $("#tree").data("kendoTreeView").options.dataSource;

Hi Alex,

thanks for your answer! I get the data if I am using this:

$("#treeView").kendoTreeView({
        dataSource: [
            {
                text: "Item 1",
                items: [
                    { text: "Item 1.1" },
                    { text: "Item 1.2" }
                ]
            },
            { text: "Item 2" }
        ]
    })

But what if I am using an unordered list (<ul><li>item</li></ul>) - can i get a serialized array / json array from the dataSource?

Thank you for your help!

Hello Ingo,

Right now, the initial data is not kept in a dataSource, so there is no array that you can get from the treeview fields. You can, however, iterate through all treeview nodes with jQuery and create the dataSource manually.

Hi guys, 

Can anyone give a quick example on how to iterate through the treeview to get at complete liste of items either as array, JSON or ul/li?
I need it to save the updated treestructure to a database.

Kind regards
Martin
