I'm attempting to display major ticks every X base units and minor ticks at every base unit along the category axis of a line chart (category labels are setup to display at the major tick position too).

The problem I'm experiencing is that as the minor ticks are rendered across the category axis, they aren't lining up correctly with the major tick (a few pixels off depending on the chart width - larger chart width makes the alignment problem more noticeable).  This is only occurring when the categoryAxis.justified is set to true.  If it is set to false, the minor ticks line up perfectly between the major ticks.

I've set up a simple example here demonstrating the problem: jsFiddle

If that doesn't work, here is the snippet:
<div id="chart"></div>
<script>
$("#chart").kendoChart({
  seriesDefaults: {
    width: 1
  },
  series: [ {
    type: "line",
    line: {
      width: 1
    },
    markers: {
      visible: true,
      size: 3
    },
    data: [1, 2, 3, 2, 4, 6, 2, 5, 1, 4, 1, 3, 4, 4, 2, 5, 6, 4, 3, 4, 2, 2, 4, 5, 6, 2, 3, 0, 1]
  }],
  categoryAxis: {
    justified: true,
    majorGridLines: {
      visible: true,
      step: 8
    },
    minorGridLines: {
      visible: true,
      step: 2
    },
    majorTicks: {
      step: 8,
      color: "#ff0000",
      size: 10,
      width: 2
    },
    minorTicks: {
      visible: true,
      step: 2,
      color: "#ff00ff",
      size: 5
    }
  }
});
</script>
The major and minor grid lines are also setup to have the same step values as the ticks and display the same behavior of minor grid lines not falling perfectly between major grid lines.

The minor ticks/grid lines seem to get more and more out of line with the major ticks/grid lines the further along the category axis they go.

The version of kendo I've been using in development is v2013.2.925 (the jFiddle version is v2013.2.918).

On another note, why do I need to specify a step value of double what I would like the base units to step for minor ticks/grid lines?  In the example I've posted you will notice that the minor ticks/grid lines are set to step every 2 base units, but they actually step every base unit when the chart is rendered.

If I include both the kendo.web.js and kendo.dataviz.js I get some bizarre errors happening.
See jsbin http://jsbin.com/uRATaJe/3/edit

This page just has an MVVM bound dropdownlist, and it keeps throwing an error.  While Chrome will go ahead and render the page correctly (edit: actually Chrome seems to crap out completely as well), Internet Explorer completely craps out.  If I remove the dataviz reference, the error goes away and all is well.

Hi,

I have a requirement of having collapsible panel in the header part of kendo grid.
It should be able to expand and collapse as well. I need this to be implemented using HTML Extension helper class.
Please provide the sample. Looking forward.

Sample code:
public static GridBuilder<T> CreateToolbarBuilder<T>(this GridBuilder<T> builder) where T : class
        {
            //add options
            return builder
                    .ToolBar(toolBar => toolBar.Template(@"@(Html.Kendo().PanelBar()
                                                                .Name('panelbar')
                                                                .ExpandMode(PanelBarExpandMode.Multiple)
                                                                .Items(panelbar =>
                                                                {
                                                                    panelbar.Add().Text('Quick Find')
                                                                   .Expanded(true)
                                                                   .Content(@<div class='toolbar'>
                                                                            <label class='category-label' for='category'>Quick Find:</label>
                                                                            <input type='search' id='category' style='width: 300px'/>
                                                                        </div>);
                                                                })
                                                            )"));
        }

Thank you.

Hi,
  I have a Kendo grid that when loaded has most of its columns hidden.
c.Bound(p => p.ServiceCost).Hidden(true).Width(100).Format("{0:$0.00}");
              c.Bound(p => p.AddressLine1).Title("Address").Width(90);
              c.Bound(p => p.City).Width(90);
              c.Bound(p => p.State).Title("State").Width(75);
              c.Bound(p => p.Zip).Width(75);
              c.Bound(p => p.ContactName).Hidden(true).Title("Contact<br/>Name").Width(100);
              c.Bound(p => p.PhoneNumber).Hidden(true).Title("Site<br/>Phone").Width(120);
              c.Bound(p => p.PhoneExtension).Hidden(true).Title("Site<br/>Ext").Width(90);
              c.Bound(p => p.Fax).Hidden(true).Title("Site<br/>Fax").Width(100);
              c.Bound(p => p.Email).Hidden(true).Title("Site<br/>Email").Width(150);
              c.Bound(p => p.Website).Hidden(true).Title("Website").Width(200);
..etc

Then i have checkboxes with the an ID that matches the model name
....
<label class="clean"><input type="checkbox" id="ContactName" class="basicChk"/>Contact Name</label></td><td>
<label class="clean"><input type="checkbox" id="PhoneNumber" class="basicChk"/>Site Phone</label></td><td>
<label class="clean"><input type="checkbox" id="PhoneExtension" class="basicChk"/>Site Phone Ext.</label></td><td>
...etc
and some JS to tie them together
$(".basicChk").bind('click', function () {
    var grid = $('#Providers').data("kendoGrid");
    if (this.checked) {
        grid.showColumn(this.id);
    }
    else {
        grid.hideColumn(this.id);
    }
});

Using Kendo UI Web v2013.2.716 All columns after the initally visible ones do not let me resize them. I've seen a past forum sayings its been fixed but its from last year
http://www.kendoui.com/forums/kendo-ui-complete-for-asp-net-mvc/grid/ie-8-bug-column-resize-handle-not-showing-on-dynamic-grid-columns.aspx

Any help or insight is greatly apprecited

Hi all,
I have a popup window which loads the content from another source.
var kendoOrderWindow = $("<div id='orderWindow' ></div>").kendoWindow({
 title: "Order "+orderIndex,
 resizable: false,
 modal: true,
 width: 1000,
 draggable: false,
 content: "myURLcontent",
 open: function (e) {
  this.wrapper.css({ top: 50 });
  }
});
kendoOrderWindow.data("kendoWindow")
 .center()
 .open()
The loaded content has a button, which should close the window
$("#button_close").click(function(e) {
    e.preventDefault();
    $('#orderWindow').data("kendoWindow").close();
});
What I find is that the close button works once, but if another orderWindow is opened after, the closebutton click event no longer fires.
If I reload the calling page the event will work again (but only once)

I have searched the forums and tried using
  $(this).closest(".k-window-content").data("kendoWindow").close();
and changing the click event to an onClick javascript function.
But none of these things seem to help.

Any ideas, suggestions to what I'm missing or doing wrong?

Hi,
I recently implemented serverPaging on my grid, however I noticed that when I sort it only sorts the data on that page and not the data as a whole.  I have added serverSorting: true, but this now stops any kind of sorting.  Can anyone assist on how to get this working or point me in the direction on some examples in PHP?   That would be much appreciated.

    $(document).ready(function() {

        $("#grid").kendoGrid({
            dataSource: {
                transport: {
                    read: {
                        dataType: "json",
                        url: "<?php echo BASE_PATH; ?>admin/account_data"
                    }
                },
                schema: {
                    total: "total",
                    data: "result",
                    model: {
                        fields: {
                            id: {type: "number"},
                            name: {type: "string"},
                            company: {type: "string"},
                            email: {type: "email"}
                        }
                    }
                },
                serverPaging: true,
                serverFiltering: true,
                serverSorting: true,
                pageSize: 25
            },
            scrollable: false,
            sortable: true,
            filterable: true,
            selectable: "row",
            detailTemplate: kendo.template($("#detailTemplate").html()),
            detailInit: detailInit,
            pageable: {refresh: true, },
            columns: [
                {field: "id", title: "ID", filterable: false},
                {field: "name", title: "Name"},
                {field: "company", title: "Company"},
                {field: "email", title: "Email"}
            ],
            editable: "inline"
        });

 // The PHP code getting the data


    function account_data() {

        //get current page from URL
        $get = $_SERVER['REQUEST_URI'];

        parse_str($get);
        if (isset($page)) {
            if ($page == 1) {
                $start = 1;
            } else {
                $start = $skip + 1;
            }
            $limit = $page * $pageSize;
        } else {
            $start = 0;
            $limit = 50;
        }

        $data= $admin->getData($start, $limit);
        $countData = $admin->countData($start, $limit);

        $data_arr['result'] = $data;
        $data_arr['total'] = $countData ;
       
$this->set('accounts_data', $data_arr);
    }

Hi,
Please take a look at the attached sample.
I'm creating a grid with a row template. As long as i havnt changed any data the blur event of each input is invoked properly.
However , after changing a value and leaving the input , the grid is re-binded and it looks like all the inputs are being recreated !!! (blur event no longer works...).
Why does the grid re-creates the entire inputs and not updates the specific input that was modified.
Currently ,when having a bigger grid this actually causes a real performance issue , as every value hang causes the grid to -rebind and the browser hangs for a second (which is very annoying to users...)
Can you please help ?
Is there a way to tell the grid to  not to be fully refreshed ?
Does it require to create a grid without using the kendo..bind command ?
If so how can I insert data-role items to the grid (if I add data-role items to the example http://demos.kendoui.com/web/grid/rowtemplate.html it doest really work...)
thx for the help

Hello Everyone,

I am writing an web application with Kendo mobile. It seems iOS 7 safari button bar will cover last item in a long liveView. See attachment please.
I am seeking a  way to either hide button bar of iOS 7 safari or resize the page itself. Anyone has suggestions?

Thanks in advance!

Hi - I have a Data Source defined for some fields on our webpage.  The first time in, it reads the data just fine.  Our users can select another value from a filter on the page, and when they click the an apply button, it should refresh the data, but it doesn't seem to do the read.  I'm not getting any errors, it just isn't doing the second read.

Any ideas?

kdsStudentInformation = new kendo.data.DataSource({
            transport: {  //transport: defines the URL endpoints for remote data (read/insert/update/delete)
                read: function (options) {
                    $.getJSON(Helpers.toServicesUrl("/GetctrlEWSStudentInfoPanel"),
                        {
                            studentId: studentIDParm,  //935824
                            username: WSIPCContext.UserName,
                            schoolCode: schoolCodeParm,
                            schoolYear: schoolYearParm,
                            districtId: WSIPCContext.DistrictId
 
                         },
                         function (data) {
                            stuInfox = data.GetctrlEWSStudentInfoPanelResult.RootResults;
                            kdsStudentInformation.data(stuInfox);
                            loadStudent();
 
                        }).fail(function (jqXHR) {
                            options.error(jqXHR);
                        });
                    //read               
                }, //transport
                schema: { //tells the Data Source where to find the result set
                    data: "stuInfox"
                }
           });

And to read it:

kdsStudentInformation.read();

thanks!

Hi Greg,

I would suggest to add "min" validation rule or define a custom one - for more information you can check this article.

Also about the template error - in current case I would suggest to add additional logic to the template where if the "vendorID" is null to return empty template. Additionally you can define "default" value for current field in the dataSource schema definition.
