I am trying to set up a call using the datasource control in a html page, based on the following:

http://docs.kendoui.com/api/framework/datasource#transportcreatedata-objectstringfunction

Below is my js function call, and what I am trying to so is pass the customer header called "key" with the value to my restful service, and not sure if I am doing this correctly or not, I am assuming not as I am not seeing this value in my service. So any help you can give on this would be appreciated. Thanks.
function mobileListViewPressToLoadMore() {
       var dataSource = new kendo.data.DataSource({
           pageSize: 20,
           serverPaging: true,
           transport: {
               create: {
                   data: { key: "34083E61DB18E3E88C80DB638C91009A9934757542B538C20E332BBC3F079BE66E79BDC70F06EED8541925D95599E834CF8877D07FAF4645A190BFA3E38A9A3FCB728E043EB8A081B279B81F6F9CED5A"
                   }
               },
               read: {
                   url: "http://services/rest/plan.svc/Patient" // the remove service url
 
 
               },
 
               parameterMap: function (options) {
                   var parameters = {
                       q: "javascript", //additional parameters sent to the remote service
                       rpp: options.pageSize,
                       page: options.page //next page
                   };
 
                   return parameters;
               }
           }, schema: { // describe the result format
               data: "", // the data which the data source will be bound to is in the "results" field
               total: function () { return 0; }
           }
       });
 
       $("#load-more").kendoMobileListView({
           dataSource: dataSource,
           template: $("#load-more-template").text(),
           loadMore: true
       });
 
   }

I am trying to make a line chart where the categoryAxis has a baseUnit of "month".

The data is an array of objects

[0].price = 34
[0].priceDate = javascriptDate

The data bind and the chart is there but it looks like a bunch of points with none of them connected by a line. OR depending on the data, some points are connected.


$("#previewChart").kendoChart({
                theme: "blueOpal",
                title: {
                    text: customDataViewModel.CustomDataName
                },
                legend: {
                    visible:false
                },
                chartArea: {
                    width: 680,
                    height:380
                },
                plotArea: {
                    margin: { bottom: 10, right: 100}
                },               
                dataSource: wth,
                series: [{
                    type:"line",
                    field: "price"
                }],
                categoryAxis: {
                    type: "date",
                    field: "priceDate",
                    baseUnit: "month",
                    labels: {
                        format: "MMM/yy",
                        title:"",
                        rotation:-90
                    }
                },
                valueAxis: {
                    
                },
                tooltip: {
                    visible: true,
                    template: "Price: #= value #<br/>Date: #= kendo.toString(category, 'MMM/yyyy') #"
                }
            });                        
        });      

I need every point to show and for them to be connected by a line.

I have some odd behavior happening in a combo box.

I have a simple combo box setup.

@(Html.Kendo().ComboBox()
                  .Name("vendorsforClass")
                  .AutoBind(false)
                  .HtmlAttributes(new { style = "width: 300px;" })
                  .DataTextField("Name")
                  .DataValueField("Id")
                  )
I have a link button that calls this javascript code.

function getVendorsForClass() {
 
        var txtValue = $("#txtSearchClassVendor").val();
 
        $.getJSON('@Url.Action("GetVendorListByClass","RCS", new {classes = "class"}, "http")/' + txtValue, function (data) {
 
            var combo = $("#vendorsforClass").data("kendoComboBox");
            combo.setDataSource(data);
            combo.refresh();
        });
}
This is the code in the controller that is creating the json object.

public JsonResult GetVendorListByClass(string classes)
        {
            var vendors = new List<VendorList>();
 
            var classId = classes.Split('/')[1];
 
            int outId;
            if (int.TryParse(classId, out outId))
            {
                vendors = new VendorListFactory().GetVendors(outId);
            }
 
            return this.Json(vendors.Select(v => new { v.Name, v.Id }), JsonRequestBehavior.AllowGet);
        }
Everything works perfectly on the first time I click on the link to populate the combo box.  If I select a value in the combo box, say for example it's Id happens to be 1234, when I click on the link again (with the intention of repopulating the combo box with different set of values) with a different value that returns back an empty object (no results in the list), the combo box is left with no values in the drop down (which would be correct), but the text in the combo box say 1234.

The box is left with the Id on the previous value I selected.  I thought when I call setDataSource it rebinds the combo box, meaning it removes previously selected values.  Why is the combo box setting it's text as the previous value (Id) that I had selected when the second datasource happens to be an empty list?

Thanks,
Tad

I have a listview where each item has a 2 divs, one with info and a second with a form, the form is hidden but when I tap the item it uses kendo.fx.expand to slide the drawer down and display the form, this part works perfectly, but when I change the input and move focus it resets the display:none on the parent div and hides it. I have no events set on the input to trigger this. And all my debug ideas so far have yielded no results.

Just a regular onblur does nothing (the div stays as it should), the problem only appears on change + blur. I've tried overriding the onchange and onblur events thru direct declaration in the input using "return false;" and using data-bind="events: {blur: ..., change: ...}" .

I also tried using jquery.slideToggle and get the same result.

Attached is a sample project that demonstrates the problem.

Any ideas on what I am doing wrong or could change?

I have 2 grids displayed on one page, our top Grid allows editing with a custom edit command.  Our lower grid allows for inline editing.  I want the ability to disable the top grid's custom Edit function (Edit button) when I click in the lower grid for inline editing using jQuery.  Below is what I have attempted

            $(function () {
                $(document).ready(function () {
                    var inlineEdit = $("#kendoGrid").data().kendoGrid.select().is(".k-grid-edit-row");
                        if (inlineEdit > 0) {
                            var edit = $("#kendoGrid").data("kendoGrid").find("k-grid-edit");
                            edit.hide();
                            e.preventDefault();
                            return false;
                       }
   });
                });

Hi,

I have two questions regarding the kendo stock chart:

1. I need to retrieve a list of the currently displayed data points (not the whole data set of the series) in the events zoomEnd, dragEnd and selectEnd in order to perform some normalization. How can this be done?

2. For the same events, how do I get the min and max of the currently displayed range of the x axis?

Thanks.

I can't get the touch demo on the site to work. I copied the source, but I can't get it running. This is my code:

<!DOCTYPE html>
<html>
<head>
    <title>Voiss</title>
     
    <script src="Scripts/kendo/last/jquery.min.js"></script>
    <script src="Scripts/kendo/last/kendo.all.min.js"></script>
    <link href="Content/kendo/last/kendo.common.min.css" rel="stylesheet" type="text/css" />
    <link href="Content/kendo/last/kendo.default.min.css" rel="stylesheet" type="text/css" />
    <link href="Content/kendo/last/kendo.mobile.all.min.css" rel="stylesheet" type="text/css" />
     
</head>
 
<body>
    <div data-role="view" data-title="Touch Events">
 
    <div
        id="touchSurface"
        data-role="touch"
        data-enable-swipe="1"
        data-touchstart="myTouch.touchstart"
        data-swipe="myTouch.swipe"
        data-tap="myTouch.tap"
        data-doubletap="myTouch.doubletap"
        data-hold="myTouch.hold"
        >
    Touch, swipe, double-tap, tap, and hold me
</div>
<div class="console"></div>
</div>
 
<script>
    window.myTouch = {
        touchstart: function(e) { kendoConsole.log("touch start"); },
        swipe: function(e) { kendoConsole.log("swipe " + e.direction); },
        tap: function(e) { kendoConsole.log("tap"); },
        doubletap: function(e) { kendoConsole.log("double tap"); },
        hold: function(e) { kendoConsole.log("hold"); }
    }
</script>
 
<style scoped>
    #touchSurface {
        background: black;
        color: white;
        padding: 20px;
        line-height: 20em;
        text-align: center;
        font-style: italic;
    }
</style>
 
 
<script>
    var app = new kendo.mobile.Application(document.body);
</script>
</body>
</html>

The js and css files are the latest, but it fails to run, both on my browsers (chrome, firefox, ie) as my tablet (android)

Hi guys,
I developing a website using tile effect to achieve a kinda of win8-like style.

I followed the example on kendo effect page and my tiles works pretty well on chrome..
the issue is that on other browser, when the tile slides to show its "back", the front is still visible...
I checked my code with the one from kendo and it seems the same...

this is my generalized javascript function to append a new tile

var rawDiv = $("<div>").append
(
     $("<div>").attr("id", idDiv).addClass("boxSlider " + other class).append (
             $("<span>").addClass("cover"),
             $("<span>").addClass("description")
     )
 )
  
return rawDiv.html();
while this is my css 
.boxSlider {
    display: inline-table;
    margin: 5px;
    overflow: hidden;
    position: relative;
}
 
    .boxSlider .cover {
        width: 100%;
        height: 100%;
        line-height: 100px;
        position: absolute;
        text-align: center;
        display: block;
        color: #fff;
        font-weight: bold;
        font-size: 18px;
    }
 
        .boxSlider .cover .bsFooter {
            width: 100%;
            font-size: 14px;
            line-height: 15px;
            bottom: 10px;
            margin: 0;
            position: absolute;
            text-transform: uppercase;
            font-weight: normal;
        }
 
    .boxSlider .description {
        display: none;
        width: 100%;
        height: 100%;
        position: absolute;
        font-size: 12px;
        color: #fff;
        overflow-y: auto;
    }
 
        .boxSlider .description span {
            display: block;
        }
 
        .boxSlider .description p {
            margin-left: 10px;
            max-width: 280px;
            min-width: 240px;
            float: left;
        }
and this is the effect

BoxSliderAnimation: function () {
        $(".boxSlider").hover(
           function (e) {
               var div = $(e.currentTarget);
               kendo.fx(div.find(".description").css("display", "block")).tile("left", div.find(".cover")).play();
           },
 
          function (e) {
              var div = $(e.currentTarget);
              kendo.fx(div.find(".description")).tile("left", div.find(".cover")).reverse();
          });
    },
I attached an image to show this behavior.

Thanks to all

I have noticed a strange (and frustrating) behavior with the NumericTextBox when used to edit rows in a modal window. When clicking inside it, the focus alternates between the textbox and the modal window. With each click, the cursor looks like it remains inside the box, but you can see the highlighting around the edges of the modal showing it's focus turning on and off. The frustrating result is that if it happens to be focused on the modal when you hit the back button trying to erase text, you navigate back in the browser. I have repeated this problem in both Chrome 24 and IE 10. However, it does not appear to occur without the modal being used.

Any idea on how I can fix this?
Thanks!
