Hi,
I am dynamically building a ul and then applying a kendoTreeView() on it everything is working prefectly fine but I am struggling to sore the tree as there is no method provided and I can't apply any logic as i am building very complicated ul.
My code as below:

function BuildTree() {

$(xmlDoc.getElementsByTagName("Item")).each(function () {

var thisItem = $(this);

var list = " "; var list1 = " ";

$(parentIDFields).each(function (index, item) {

if (thisItem.attr(item) != null && thisItem.attr(descriptionCol) != null) {

if (index == 0) {

list += "<li id=" + thisItem.attr("ID") + " onclick=sendHTML(" + thisItem.attr("ID") + ");>" + thisItem.attr(item);

list1 += "</li>";

}

else {

list += "<ul><li id=" + thisItem.attr("ID") + " onclick=sendHTML(" + thisItem.attr("ID") + ");>" + thisItem.attr(item);

list1 += "</li></ul>";

}

});

$("#treeView").append(list + "<ul><li id=" + thisItem.attr("ID") + ">" + thisItem.attr(descriptionCol) + " </li></ul>" + list1);

});

$(document).ready(function () {

$("#treeView").kendoTreeView();

});

}

can you please show any pointers towards solution.

Binding combobox to a remote Rest Service.

I want to bind the combo box to a remote rest service which takes a partial name as query string parameter. Following is the code I have.

$("#combobox").kendoComboBox({

dataTextField: "Description",

dataValueField: "Code",

filter: "contains",

minLength: 3,

autoBind: false,

dataSource: {

type: "json",

serverFiltering: true,

transport: {

read: {

url: serviceUrl + "HpCodes",

contentType: "application/json; charset=utf-8",

dataType: "json",

data: {

partialName:

function () {

return $("#combobox").val();

}

});

So I was hoping when uses types in 3 chars it would emit a call to the service as <serviceUrl>/HpCodes?partialName=tes
but it doesn't seem to be doing that instead it sends the following request
GET <serviceUrl>/HpCodes?partialName=&filter%5Blogic%5D=and&filter%5Bfilters%5D%5B0%5D%5Bfield%5D=Description&filter%5Bfilters%5D%5B0%5D%5Boperator%5D=contains&filter%5Bfilters%5D%5B0%5D%5Bvalue%5D=tes HTTP/1.1
This looks like a oData query annd in my wcf service the partialName is empty string.

Another thing I noticed was that even though I set the minLength to 3 if I click the drop down button with out entering anything the the input area it still calls the service.

Server paging and ListView's loadMore

In odata __next is specified to let the datasource know how to request more results. I'm using hand rolled json and my listview isn't showing the loadmore button. What do I need to do to let it know it should request the same URL but increment the page number?

var ds = new kendo.data.DataSource({

transport: {

read: {

url: "http://localhost:3000/api/anagram",

dataType: "jsonp",

data: {

format: 'html'

}

},

parameterMap: function(options) {

if (options.filter && options.filter.filters.length > 0)

return {

rack: options.filter.filters[0].value.replace(/\?/g,'-'),

format: 'html',

limit: options.pageSize,

page: options.page

};

return options;

}

},

group: 'length',

pageSize: 10,

page: 1,

sort: {field: 'w', dir: 'asc'},

filter: { field: 'rack', operator: 'eq', value: 'z' },

serverFiltering: true,

serverPaging: true,

serverGrouping: true,

serverSorting: true,

error: function(e){

alert(e);

console.log(e);

},

change: function(e) {

console.log('Data changed: ' + this.total());

},

schema: {

groups: 'groups',

total: 'count',

model: {

fields: {

length: {

type: 'number'

},

w: {

type: 'string'

},

f: {

type: 'string'

}

});

JSON ommit field if the value is null

Hi,
My json rest service omits fields when the values is null and looks like GRID can't handle such datasources.

Number is not null

{

{
    "id":"0422842A222780",
    "number":"0422842A222780"
  }

Number is null
{
    "id":"0422842A222780"
  }
model:{
    id:"id",
    fields:{
        id:{type:"string", editable:false},
        number:{type:"string", editable:false, nullable:true},
    }
}

As a result I see empty grid.
When I remove this field from displaying all works fine
Is there any solution?

Indexed db abstraction layer

I am wondering if telerik is planning on developing any kind of abrstraction layer for accessing indexed db architecture.

Quite annoyingly the W3C has killed WebSQL and indexed db is such a new standard that every browser that does support it (currently only 2 that I am aware of Chrom and FireFox) have there own way of managing the db and from what I am seeing IE 10- will have alltogetehr a different way to manage its indexed db implimentation.

This has long been a sore spot for me with open source development that standards are often not only times implimented accross differently accross platforms, but from version to version you can have entire subsets of functionality be cycled out (especially on new and rapidly evolving items like indexed db.. It make building stable applications that utilize these technologies exceedingly difficult.

I have not only a desire but a genuine need to see data storage for certain application fucntions occur on the client side but I cant do that without some kind of stability in the evolving landscape of the applications platform. I DEFINATELY dont desire to develope three seperate constantly shifting approaches to implimenting a client side data storage solution. Does Teelrik have any plans to impliment some kind of client side data storage abstraction layer that woudl allow you to utilize client side storage like indexed db with its controls sets?

virtual scrolling and editable mutually exclusive?

Hey there,

While working on a CRUD demo using OpenAccess as Odata producer and KendoUI I'm facing with an issue with the command columns when virtual scrolling is enabled.
Virtual scrolling is working as expected in Firefox without the command columns: http://openaccess.spirit.de/.

Once the comand columns are enabled http://openaccess.spirit.de/?ReadWrite=1 it's no longer possible to use the scroll bar.

My guess is that the larger row height is causing this, but I haven't found time yet to dig deeper into it.

Thanks,

Rainer

Using a Kendo UI mobile icon without a button

Hi There,

Is there a way to use the mobile icons/images outside of a button (or with a tab strip, or listview etc.), so for example to display the search icon alone in a div using something like:

<div data-role="icon" data-icon="search"></div>

I'm trying to use the search icon, next to a search input tag for searches in my prototype.

Thanks,
Rob
