Grid Change event fires 2 times

When I set up a grid to selectable: "row" and capture the change event I see the change event fire twice here is a really simple grid to use as an example:
<html>
<head>
<script>
var data = [
    {"col_a": "vala1","col_b": "valb1","col_c": "valc1"},
    {"col_a": "vala2","col_b": "valb2","col_c": "valc2"},
    {"col_a": "vala3","col_b": "valb3","col_c": "valc3"},
    {"col_a": "vala4","col_b": "valb4","col_c": "valc4"}
           ];
        $(document).ready(function () {
            if(typeof(data) != "undefined")
            {
                $("#grid1").kendoGrid({
                        dataSource: {data: data},
                        columns: [
                        {field: "col_a", title:"ColA"},
                        {field: "col_b", title:"ColB"},
                        {field: "col_c", title:"ColC"}
                        ],
                        sortable: true,
                        resizable: true,
                        width: "95%",
                        height: "400px",
                    selectable: "row",
                        change: function(e){
                                alert('change');
                                }
                });
            }
            else
            {
                $("#grid1").addClass("k-block");
                $("#grid1").text("No data.");
                $("#grid1").css("font-weight", "bold");
                $("#grid1").css("font-size", "14px");
                $("#grid1").width(400);
            }
        });
</script>
</head>
<body>
<div id="grid1" style = "width:99%;"></div>
</body>

its also in action here: http://jsfiddle.net/jnv9M/

Any way to prevent this or any help as to why I'm getting this event twice?

Treeview - add html to item

Complete Code From here:
http://pastebin.com/LHa83w57

OR:

<script>

-

$("#treeview-images").kendoTreeView({

dataSource: [

{

text: "Inbox", imageUrl: "../../content/web/treeview/mail.png",

items: [

{ text: "Read Mail", imageUrl: "../../content/web/treeview/readmail.png" },

{ text: "adasd" , imageUrl: "../../content/web/treeview/readmail.png" }

]

},

{

text: "Drafts", imageUrl: "../../content/web/treeview/edit.png"

text: "Search Folders", expanded: true, imageUrl:"../../content/web/treeview/search.png",

items: [

{ text: "Categorized Mail", imageUrl: "../../content/web/treeview/search.png" },

{ text: "Large Mail", imageUrl: "../../content/web/treeview/search.png" },

{ text: "Unread Mail", imageUrl: "../../content/web/treeview/search.png" }

]

},

{

text: "Settings", imageUrl: "../../content/web/treeview/settings.png"

}

]

});

</script>

How is this possible? I have tried:
{ text: document.write('Read <br> Mail'); , imageUrl:"../../content/web/treeview/readmail.png" },

But then it does not display me anything (not even the tree View).

what format is given me the datePicker

Hello again,

if i have a kendo DatePicker
and i get the value of that something like that:
var startDate = $(employee.currentStartDate).data("kendoDatePicker").value().toString();
i send to the server as a string,but i try to parse this date in .net C#
i tried something like

public ActionResult GetEndDateValues(string startDate)
        {

            DateTime contractVersionStartDate = DateTime.ParseExact(startDate, "g", null); also i tried G,D,d,still not recognized
}
if on the client,i put toUTCString(),or toISOString(), then the date is 2 hour behind,so i get the yesterday date(ex. 26.11.2013,i get 25.11.2013 22:00:00 pm)
is not ok.
so can you help me clarify this?
i want no matter what local culture is,to send it from client,and parse right on the server.

Best Regards,
Daniel

P.S:if i enter in my telerik account,and i click on a post,no longer sends me to my post,i have to look over it,in the whole kendo forum.before it wasn't like that.

Position of validation tooltip for radio button list

Hello,

I am trying to use the kendo validation with a set of radio buttons inside of a kendo template. i've been able to validate whether or not there is at least one radio button selected per set but I cannot seem to get the validation tooltip to be located where I want it to. Basically each template item has a radio button list with each items name and id set to the same value. When the validation fires it places the tooltip in the first radio button list items label area. I'd like it to be above the list of radio button items. Please see my code below:

<div id="kendo-content" class="k-content">
        <div id="divSubgroups" style="border: none; border-top: 1px dashed #ccc;" data-bind="source: lstSubgroups" data-template="SubgroupTemplate"></div>
    </div>

    <script type="text/x-kendo-template" id="SubgroupTemplate">
        <div class="item">
            <div class="left">
                <h3>#:Name#</h3>
                <br />
                <p>Current Due: <strong>#:kendo.toString(AmountOwed, "c")#</strong></p>
                <br />
                <p><button id="btnAddPaymentAccount" type="button" class="Orange">Add Payment Account</button>


            </div>
            #if(Accounts.length > 0){#
                <div style="float: right">
                    <h3>Select Payment Account:</h3>
                    <span class="k-invalid-msg" data-for="radio#:ID#"></span>
                    <ul style="margin: 0;" data-bind="source: Accounts" data-template="AccountTemplate"></ul>
                    <br />
                    <span class="left"><button id="btnEditPaymentAccount" type="button" onclick="Validate('#:ID#');">Edit Account</button></span>
                    <span style="float: right"><button id="btnPayBill" type="button" onclick="Validate('#:ID#');">Pay Bill</button></span>
                </div>
            #}#
            <div style="clear: both;"></div>
        </div>
    </script>

    <script type="text/x-kendo-template" id="AccountTemplate">
        <li>
            <label>
                <input type="radio" id="radio#:ParentID#" name="radio#:ParentID#" value="#:ID#" />
                #:Descriptor#
            </label>
        </li>
    </script>
    <script>
        function Validate(id)
        {
            var validator = $("#radio" + id).kendoValidator({
                rules: {
                    custom: function (input) {
                        var v = $("#radio" + id + ":checked").length;
                        return v > 0;
                    }
                },
                messages: {
                    custom: "Please select a payment account to continue."
                }
            }).data("kendoValidator").validate();
        }
    </script>

The data model for this is as follows:
lstSubgroups:
[
   {
       ID:"P001",
       Name:"Test Name 1",
       AmountOwed:200,
       Accounts: [
                       { ParentID:"P001", ID:9318, Descriptor:"Personal Card #1" },
                       { ParentID:"P001", ID:9319, Descriptor:"Personal Card #2" },
                       { ParentID:"P001", ID:9320, Descriptor:"Personal Card #3" }
                  ]
   },
   {
       ID:"P002",
       Name:"Test Name 2",
       AmountOwed:100,
       Accounts: [
                       { ParentID:"P002", ID:1515, Descriptor:"Company Card #1" },
                       { ParentID:"P002", ID:2356, Descriptor:"Company Card #2" }
                  ]
   },
   {
       ID:"P003",
       Name:"Test Name 3",
       AmountOwed:500,
       Accounts: [
                       { ParentID:"P003", ID:2342, Descriptor:"Parents Card #1" },
                       { ParentID:"P003", ID:1122, Descriptor:"Parents Card #2" },
                       { ParentID:"P003", ID:786, Descriptor:"Parents Card #3" }
                  ]
   }
]

I've tried adding "<span class="k-invalid-msg" data-for="radio#:ID#"></span>" but it doesn't seem to have any effect.

Your help is greatly appreciated!
Matt

TabStrip initially rendering incorrectly in some browsers

I'm using the PHP wrappers to generate a mildly complex tabstrip based form. In Chrome and Firefox the tabstrip initially renders with all of the tabs as one long unformatted div before refreshing itself a second or two later and displaying correctly. In both Opera and IE (yeah IE) it renders correctly without the initial hiccup

Test page: http://raymondandrews.com/crftest
Source: http://raymondandrews.com/crftest/index.txt

I'm not loading tabs with ajax or from a database, right now it's all manually configured

MVVM grid: Where is the documentation for the 'data' attributes for the grid

Can someone please guide me to the documentation for all the 'data' attributes supported on the grid for use in MVVM. I have guessed at a few and saw some in samples. I need the full list please

I am using these:
data-role="grid"
data-bind="source: gridSource"
data-columns='ProductName'
data-sortable='true'
data-editable='inline'

I guessed at 'data-sortable' and it worked. I tried 'data-filterable' but it did NOT work. No filter icons appeared in the column headers. So is filtering supported in the MVVM grid? whats the 'data' attribute for this?

Thanks

DataBounded event

Hello,

A while a go, posted this question about how to select a row after a grid refresh.

The answer given back then was a great workaround. However, once deployed in production with large amount of data, I realized many client's grid were not loaded within 50 milliseconds, leaving the first row unselected.

Increasing the delay might fix the problem for some people but how long should we wait to make sure every grids are loaded? In the other hand, I don't want to add transform my problem into unnecessary.

What's missing here is an event triggered by the Grid.

Is there a way to create an event named DataBounded (or AfterDataBound) that would fired once the grid will complete the loading of the data received from the dataSource?

Best regards,

Simon

Grid binding to a One-to-many Model

Hi All

I'm trying to get the Kendo Grid to display with a hierarchical row displaying history data for a given row.
My colleague has setup the project with the primary model having a one to many relationship to the second model.
Models are as follows:

public class CrossReferenceRelationship

{

public int Id { get; set; }

[Display(Name = "From Partner")]

public string FromPartner { get; set; }

[Display(Name = "To Partner")]

public string ToPartner { get; set; }

[Display(Name = "From Role")]

public string FromRole { get; set; }

[Display(Name = "From Account")]

public string FromAccount { get; set; }

[Display(Name = "To Account")]

public string ToAccount { get; set; }

[Display(Name = "Is Deleted")]

public bool IsDeleted { get; set; }

public ICollection<CrossReferenceRelationshipHistoricEntry> HistoricEntries { get; set; }

}

public class CrossReferenceRelationshipHistoricEntry

{

public int Id { get; set; }

public int XrefId { get; set; }

[Display(Name = "From Partner")]

public string FromPartner { get; set; }

[Display(Name = "To Partner")]

public string ToPartner { get; set; }

[Display(Name = "From Role")]

public string FromRole { get; set; }

[Display(Name = "From Account")]

public string FromAccount { get; set; }

[Display(Name = "To Account")]

public string ToAccount { get; set; }

[Display(Name = "Action Type")]

public string ActionType { get; set; }

[Display(Name = "Method Used")]

public string MethodUsed { get; set; }

[Display(Name = "Modified By")]

public string ModifiedBy { get; set; }

[Display(Name = "Modified Datetime")]

public DateTime ModifiedDatetime { get; set; }

}

He then maps these using EntityMapper, populating these objects.
So far my view contains the following code for the Kendo grid:

@(Html.Kendo()

.Grid(Model)

.Name("adminGrid")

.Columns(columns =>

{

columns.Bound(crr => crr.Id).Filterable(false).Width(100);

columns.Bound(crr => crr.FromPartner).Width(200);

columns.Bound(crr => crr.FromAccount).Width(200);

columns.Bound(crr => crr.ToPartner).Width(200);

columns.Bound(crr => crr.ToAccount).Width(150);

columns.Command(command => { command.Edit(); command.Destroy(); }).Width(180);

})

.ToolBar(toolbar => toolbar.Create())

.Editable(editable => editable.Mode(GridEditMode.InLine))

.Pageable()

.Sortable()

.Scrollable()

.ClientDetailTemplateId("HistoricEntries")

.Filterable()

.HtmlAttributes(new { style = "height:430px;" })

.Events(events => events.DataBound("dataBound"))

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(20)

.Events(events => events.Error("error_handler"))

.Model(model => model.Id(crr => crr.Id))

.Create(update => update.Action("Partner_Create", "CrossReferenceRelationship"))

.Read(read => read.Action("Read", "CrossReferenceRelationship"))

.Update(update => update.Action("Update", "CrossReferenceRelationship"))

.Destroy(update => update.Action("Delete", "CrossReferenceRelationship"))

)

<script id="HistoricEntries" type="text/kendo-tmpl">

@(Html.Kendo().Grid<CrossReferencePortal.Models.CrossReferenceRelationshipHistoricEntry>()

.Name("historyGrid_#=Id#")

.Columns(columns =>

{

columns.Bound(he => he.FromPartner);

columns.Bound(he => he.FromAccount);

columns.Bound(he => he.ToPartner);

columns.Bound(he => he.ToAccount);

columns.Bound(he => he.FromRole);

columns.Bound(he => he.ActionType);

columns.Bound(he => he.MethodUsed);

columns.Bound(he => he.ModifiedBy);

columns.Bound(he => he.ModifiedDatetime);

})

.DataSource(dataSource => dataSource

.Ajax()

.PageSize(5)

.Read(read => read.Action("HistoryRead", "CrossReferenceRelationship", new { Id = "#=Id#" }))

)

.Pageable()

.Sortable()

.ToClientTemplate()

)

</script>

I feel I should be able to bind the history grid to the primary grid's Model, so that I can simple expose the HistoricEntries e.g.
crr.HistoricEntries

Is this possible and are there any examples showing something similar?

Many thanks
Christian

Move valueAxis to min with 'object' data (vs 'array' data)

Hi All,

I was trying to move the valueAxis to the minimum value, however this is not working when the data is an object compared to the examples where it uses data arrays. Is there a way to move the axis with this kind of configuration? Please see the following jsFiddle:

http://jsfiddle.net/kousei2040/D42M6/10/

Thanks in advance.
