Rebuild TreeView with new data

Hello,

I want to rebuild the Treeview with new data. I use this code:

$(#treview)

.removeClass('k-treeview')

.empty();

$(#treeview).kendoTreeView({

dataSource: getNewdata(),

select: onNodeSelect

});

The tree is rebuild well but the function onNodeSelect is called two times if I select a node.
Is there a way to clear also event handling for select?

{

groupable: true,

scrollable: true,

sortable: true,

pageable: true,

</script>

Controller:

public JsonResult GetItems()

{

List<SelectListItem> searchParams = new List<SelectListItem>();

searchParams.Add(new SelectListItem() { Value = "InvNo", Text = "121" });

IList<Item> data = _itemService.GetItems(searchParams);

Add command with local data

Hi,

Considering the fiddle here : http://jsfiddle.net/sT94F/3/

When clicking the "Add" button, there's a reference error, "colA is not defined".

Is there a way I can pass an "empty" object when adding the row?

I am using v2012.1.327

Thanks,

Pascal.

Custom Paging

I am trying to do a custom paging by using mvvm, datasource and template. My problem is I have to use this.set to set the dataSource page() or total pages() to get the value this.get("dataSource").totalPages() or this.get("dataSource").page() refreshed. That is why I set a variable pageRefreshHolder as work-around. Is there some easy way?

var viewModel=kendo.observable({

dataSource:new kendo.data.DataSource({

data:ReportsData,

pageSize:12,

sort:{ field: "name", dir: "asc" }

}),

copy:function(e){

this.dataSource.add(e.data);

this.set("pageRefreshHolder",this.dataSource.totalPages()); //I have to have this line to get the totalPage work

},

goToNextPage:function(){

if(this.dataSource.page()<this.dataSource.totalPages())

this.dataSource.page(this.dataSource.page()+1);

else

this.dataSource.page(1);

$jquery("#reportsArea").find("div#phItem").show("slide",{direction:"right"}, 500);

this.set("pageRefreshHolder",this.dataSource.page()); //I have to have this line to get the currentPage work

},

goToPrevPage:function(){

if(this.dataSource.page()>1)

this.dataSource.page(this.dataSource.page()-1);

else

this.dataSource.page(this.dataSource.totalPages());

$jquery("#reportsArea").find("div#phItem").show("slide",{direction:"left"}, 500);

this.set("pageRefreshHolder",this.dataSource.page()); //I have to have this line to get the currentPage work

},

pageRefreshHolder: 1,

totalPage: function() {

return this.get("dataSource").totalPages();

},

currentPage: function(){

return this.get("dataSource").page();

}

});

kendo.bind($jquery("#reportsArea"),viewModel);

[Solved] N Level ListView Design Pattern

I want to create some what of a product catalog using listviews. Basically the page will start with a listview of high level categories. When a person selects a category, I will perform a jsonp query and they will see a new listview with the subcategories of that category. I don't know ahead of time how deep the categories can be nested but it seems that there should be a simple design pattern so this can be done with a single page that can be reused over and over at each level and that each (different page/category query) could be cached to avoid making the same jsonp request.

Would appreciate if someone can point me in the right direction.

Thanks,
EE
