[Solved] NodeClick

[Jeroen Eikmans]

Hello,

I have a Treeview with Binding to a List<CustomerObject>  in my model, this is the same as the Binding to Model Demo.
In the ClientEvent OnLoad i have to following code

function MasterTreeviewLoad(e) {
        var treeView = $('#Treeview').data('tTreeView');

        var node = $("> ul > li", treeView.element)[0];

        treeView.nodeClick(e, node);
    }

What i am attempting to do is have the first node selected after the treeview is done loading.The code above however is not working.
Does anybody have an idea about what i'm doing wrong?

Hello Roel,

The nodeClick method is not meant to be used that way (it's more of a private method). You can select the first node by triggering a click event (if you need to fire the onSelect event) or by simply adding a t-state-selected class:

// triggers onSelect
$("> ul > li", treeView.element).eq(0).trigger("click");

// does not trigger onSelect
$("> ul > li", treeView.element).eq(0).addClass("t-state-selected");

Hello Alex,

OK, i understand i shouldn't use the nodeClick method.
I do need the OnSelect to be triggered so i'm using the first line but unfortunatly i am not able to get the click to work.

I attached a small app is used to try the functionality. Is it possible you take a quick look at it and tell me what i'm doing wrong?
Thanks for your help!

Hi Roel Martens,

Sorry, my bad -- the correct code should have been as follows:

// triggers onSelect
$("> ul > li > div > .t-in", treeView.element).eq(0).trigger("click");

// does not trigger onSelect
$("> ul > li > div > .t-in", treeView.element).eq(0).addClass("t-state-selected");

or, to keep things short (finding the first .t-in element),

// triggers onSelect
$(".t-in:first", treeView.element).trigger("click");

// does not trigger onSelect
$(".t-in:first", treeView.element).addClass("t-state-selected");

The modified Index.cshtml is attached.
