BUG: event passed to click event handler does not tell you which action button has been clicked

To reproduce:

Take the sample at http://demos.kendoui.com/mobile/actionsheet/index.html
Modify to call the same event handler

<ul data-role="actionsheet" id="inboxActions" data-open="onOpen" data-popup='{"direction": "left"}'>

<li class="km-actionsheet-title">Monday Meeting:</li>

<li><a href="#" data-action="reply">Reply</a></li>

<li><a href="#" data-action="replyAll">Reply All</a></li>

<li><a href="#" data-action="archive">Archive</a></li>

</ul>

becomes

<ul data-role="actionsheet" id="inboxActions" data-open="onOpen" data-popup='{"direction": "left"}'>

<li class="km-actionsheet-title">Monday Meeting:</li>

<li><a href="#" data-action="singleEventHandler">Reply</a></li>

<li><a href="#" data-action="singleEventHandler">Reply All</a></li>

<li><a href="#" data-action="singleEventHandler">Archive</a></li>

</ul>

Then try implementing singleEventHandler as below:

function singleEventHandler(e) {

if (<some test involving e>) {

$("#actionResult").html("Replying to message #" + e.context);

} else if (<some other test involving e>) {

$("#actionResult").html("Replying to all in message #" + e.context);

} else if (<some other test involving e>) {

$("#actionResult").html("Archiving message #" + e.context);

}

     doMoreStuff();

}

The problem is e only has two properties: target and context

target is not the button which has triggered the event but the button which has opened the action sheet, so there is no way to know which button in the action sheet has been triggered in the event handler.

If not a bug, this is in my opinion a design issue which prevents properly factoring code as the only workaround is to multiply event handlers when it is not always necessary.

How to use 2 different values on a client template?

Here is a snippet:

columns.Bound(p => p.URL).Title("Url").Visible(false);

columns.Template(p => p.TRACKINGNUMBER).ClientTemplate(

"<a href='#= URL #'>#= TRACKINGNUMBER #</a>"

).Title("Tracking Number");

The above above client template ignores the URL value and simply displays the tracking number has a regular text field.

Reference to current item in a template

Inside an MVVM bound template, how do I get access to the data item itself?

This doesn't give it to me (clearly eh) :)

<li data-bind="invisible: #= console.log(this) #">

<span>test</span>

</li>

.data("kendoDropDownList").bind("dataBound" When exactly is this supposed to run?

So frustrating.

I have a scenario not extremely complicated in which i require items in my drop-down actually be databound before selecting a default item.

So when does this databound event actually run? Inside my databound event handler i am checking the count of items in the dropdownlist and it is ZERO.

I have been trying to track down phantom errors which are a result of either this bug or a misunderstanding of the docs for 2 weeks. Can someone from telerik expand on this? from the telerik api:

dataBound

Fires when the drop-down list has received data from the data source.

Example

$("#dropdownlist").kendoDropDownList({
    dataBound: function(e) {
        // handle event
    }
});

To set after initialization

// get a reference to the dropdown list
var dropdownlist = $("#dropdownlist").data("kendoDropDownList");
// bind to the close event
dropdownlist.bind("dataBound", function(e) {
    // handle event
});

Have i misread "receive" data to mean received and bound the data? When really it's not databound? If so it would be extremely useful to have an actual databound event for the dropdownlist that was fired AFTER the items have been created.

[Solved] Error when using logic in ClientRowTemplate

I meant ClientTemplate. It won't let me edit the title of this post.

columns.Bound(t => t.IsOpen)
.Title("Status")
.ClientTemplate(
"# if (#=IsOpen# == 'True') { #" +
"something" +
"# } else { #" +
"something else" +
"# } #"
);

Uncaught Error: Invalid template:'<tr data-uid="#=uid#"><td ># if (#=IsOpen# == 'True') { #something# } else { #something else# } #</td></tr>' Generated code:'var o,e=kendo.htmlEncode;with(data){o='<tr data-uid="'+(uid)+'"><td >'; if (;o+='=IsOpen'; == 'True') { ;o+='something'; } else { ;o+='something else'; } ;o+='</td></tr>';}return o;'

Problem when closing modal window

I need to create a scheme where my pages open windows within the iframe contained in KendoWindow.
To establish a modal window I need to create it from within my home, because if you create it within a modal child page to only cover the child page.
I'm having to develop a scheme for windows like a desktop application.
Below is the JavaScript library I wrote to do this for me:

var kendoWindowFactory = new function () {

var __modalKendoWindow;

var __functionCallback;

this.createKendoWindow = createKendoWindow;

this.createModalKendoWindow = createModalKendoWindow;

this.modalReturn = modalReturn;

function createKendoWindow(element) {

var frameId = "___kendoWindow_" + element.id;

var LINK = element.href;

var TITLE = $(element).attr("data-title");

var WIDTH = $(element).attr("data-width");

var HEIGHT = $(element).attr("data-height");

if (!(parseFloat(WIDTH) > 0)) {

WIDTH = "50%";

}

if (!(parseFloat(HEIGHT) > 0)) {

HEIGHT = "50%";

}

var kendoWindow = document.getElementById(frameId);

if (kendoWindow) {

$(kendoWindow).data("kendoWindow").toFront();

}

else {

kendoWindow = $("<div />")

.attr({ id: frameId })

.appendTo("body");

$(kendoWindow).kendoWindow({

title: TITLE,

modal: false,

width: WIDTH,

height: HEIGHT,

content: LINK,

visible: false,

deactivate: function () {

this.destroy();

},

}).data("kendoWindow").center().open();

$(kendoWindow).css({ overflow: "none" });

}

return false;

}

function createModalKendoWindow(element, functionCallback) {

var frameId = "___kendoWindowModal_";

__modalKendoWindow = null;

__functionCallback = functionCallback;

var LINK = element.href;

var TITLE = $(element).attr("data-title");

var WIDTH = $(element).attr("data-width");

var HEIGHT = $(element).attr("data-height");

if (!(parseFloat(WIDTH) > 0)) {

WIDTH = "770px";

}

if (!(parseFloat(HEIGHT) > 0)) {

HEIGHT = "470px";

}

var kendoWindow = document.getElementById(frameId);

if (!kendoWindow) {

kendoWindow = $("<div>").attr({ id: frameId }).appendTo("body");

}

__modalKendoWindow = $(kendoWindow).kendoWindow({

title: TITLE,

modal: true,

width: WIDTH,

height: HEIGHT,

visible: false,

deactivate: function () {

this.destroy();

},

}).data("kendoWindow").center().refresh(LINK).open();

$(kendoWindow).css({ overflow: "none" });

return false;

}

function modalReturn(value) {

__modalKendoWindow.close();

if (value) {

if (__functionCallback) {

__functionCallback(value);

}

The application is being written with Visual Studio 2012 with a WebForms application.

So I set my menu to open the windows. This is the main page:

<script>

$(function () {

$('#tabMenu a').click(function (e) {

e.preventDefault();

kendoWindowFactory.createKendoWindow(this);

});

$(document).ready(function () {

$("#tabMenu").kendoTabStrip();

});

</script>

So I set the child pages (which are opened within kendoWindows using iframe) to open a modal window.
Fits a search window, for example:

<script type="text/javascript">

function returnValue(value) {

document.getElementById("<%= txtCodigo.ClientID.ToString() %>").value = value;

__doPostBack("Municipio.aspx", "txtCodigo_TextChanged");

}

$(function () {

$("#<%= btnConsultar.ClientID.ToString() %>").click(function (e) {

e.preventDefault();

window.parent.kendoWindowFactory.createModalKendoWindow(this, returnValue);

});

</script>

Every kendoWindow is created and removed dynamically.

To return a selection made in the modal window use this code:

<script type="text/javascript">

$(function () {

$("#grvMunicipio").kendoGrid({

columns: [

{ field: "Codigo", title: "Código" },

{ field: "Descricao", title: "Município" },

{ field: "Uf", title: "Estado" }

],

dataSource: {

pageSize: 15

},

sortable: true,

selectable: true,

pageable: {

refresh: true,

pageSizes: true

}

});

$('#grvMunicipio').dblclick(function () {

var Grid = $("#grvMunicipio").data("kendoGrid")

Grid.select().each(function () {

var dataItem = Grid.dataItem($(this));

RetornaValor(dataItem.Codigo);

});

</script>

I use a callback routine passed as a parameter to the main page, the JavaScript function created, which is to destroy the modal window and return the value to the desired field.

My problem is: When I open the modal window by button link child window, the child window is frozen.
I close the modal and I can no longer use the controls / window elements daughter.
However, when moving the child window with the mouse controls are released.

The child page now has no code in your code behind.

Can anyone help me with a particular problem?

From now on, thank you all!

Window
