kendojs template data-bind click event not working - kendo-ui

Well, I am using KendoJS grid and I have this code here in my .js file:
var viewModel = kendo.observable({
people: new kendo.data.DataSource(...),
isActive:true,
friends: new kendo.data.DataSource(...),
selectionChanged: function(){...
}
});
$(document).ready(function () {
kendo.bind($("#sampleGridContainer"), viewModel);
});
In my .html file, I have a kendo grid:
<div id="sampleGridContainer">
<div data-role="grid"
data-columns="[...]"
data-editable="{ 'mode': 'popup', 'template': kendo.template($('#sampleTemplate').html()) }"
data-bind="source: people"></div>
</div>
<script id="sampleTemplate" type="text/x-kendo-template">
<form id="sampleForm">
...
<div data-container-for="somedropdown" class="k-edit-field">
<input name="somedropdown" id="somedropdown"
data-role="dropdownlist"
data-type="text"
data-text-field="name"
data-value-field="value"
data-bind="value: someValue, visible: isActive, source: friends, click: selectionChanged" />
</div>
...
</form>
</script>
Now, in my dropdown input element, someValue, isActive and friends variables are properly working - infact the drop down list shows up fine. But the problem is click event selectionChanged is not called. If I remove this from template, the event starts working, but my question is when all the other variables on the same scope are accessible in template, why does event selectionChanged not get called?
Any help is highly appreciated.

I have also encountered this problem, my workaround for this is that I initialize my kendoDropDownList on the edit event of grid.
edit: function (e){
e.container.find("input[name='somedropdown']").kendoDropDownList({
dataTextField: "name",
dataValueField: "value",
data-bind="value: viewModel.someValue, visible: viewModel.isActive, source: viewModel.friends, click: viewModel.selectionChanged"
});
}
Then the html would look something like this:
<div data-role="grid"
data-columns="[...]"
data-editable="{ 'mode': 'popup', 'template': kendo.template($('#sampleTemplate').html()) }"
data-bind="source: people, events: { edit: onEdit }">
</div>
<script id="sampleTemplate" type="text/x-kendo-template">
<form id="sampleForm">
<div data-container-for="somedropdown" class="k-edit-field">
<input name="somedropdown"/>
</div>
</form>
</script>
Hope this works for you.

Kendo upload - how to add a javascript event handler for file remove button click

My kendo template is as follows:
<div id="file-err-msg" > Please remove files with errors</div>
<input name="files" id="files" type="file" />
<script id="fileTemplate" type="text/x-kendo-template">
<span class='k-progress'>
</span>
<strong class='k-upload-status'>
<button type='button' class='btn-remove k-button k-button-bare k-upload-action'>
<span class='k-icon k-i-close k-delete' title='Remove'></span>
</button>
</strong>
</script>
<script>
$("#files").kendoUpload({
template: kendo.template($('#fileTemplate').html())
});
</script>
I need to hide the div with id - file-err-msg, when the remove button is clicked. the Remove action is happening when the span with css class "k-delete" is clicked. I need to add the below event handler in addition, and it is never being called.
$(".k-delete").click(function () {
alert("Remove button clicked");
});
since these controls are rendered dynamically, i tried to bind them to the event handler as below, but nothing works.
$("body").on("click", ".btn-remove", function () {
alert("dynamic control event handler");
});
Any help is appreciated!
According to Kendo Upload API documentation, you can bind a function to the remove event.
So this is where you could hide your file-err-msg div :
$("#files").kendoUpload({
template: kendo.template($('#fileTemplate').html()),
remove: function(e) {
$('#file-err-msg').hide();
}
});

What's the best way to add the same ajax function to a list of comments?

Source code is like this:
<div>
<h4>comment content</h4>
<a id="delcmt_{{ comment.id }}">delete this comment</a>
</div>
......
<div>
<h4>comment content</h4>
<a id="delcmt_{{ comment.id }}">delete this comment</a>
</div>
I what to add ajax function to each of the "delete this comment" link:
<script type=text/javascript>
$(function() {
$('a#delcmt_id').bind('click', function() {
$.get($SCRIPT_ROOT + '/del_comment', {
}, function(data) {
$("#result").value(data.result);
});
return false;
});
});
</script>
What I can come out is using a loop to copy the upper ajax function for each comment, that must be very ugly. Any good ideas?
Try adding a class and select it with jquery add an event handler. You have to use the 'on' event because the elements you wish attach behavior to might be dynamic and load after document ready.
#*Render all this with razor, or angular or knockout*#
<div>
<h4>comment content</h4>
<span style="cursor: pointer;" id="1" data-rowid="1" class="delete-me-class">delete this comment</span>
</div>
<div>
<h4>comment content</h4>
<span style="cursor: pointer;" id="2" data-rowid="2" class="delete-me-class">delete this comment</span>
</div>
<script>
$(function () {
$('body').on('click', '.delete-me-class', function () {//http://api.jquery.com/on/ on is the latest 'live' binding for elements that may not exists when DOM is ready.
var rowId = $(this).data('rowid');
//TODO Use rowId for your delete ajax, or your element Id if you wish.
alert('You clicked on the delete link with the row ID of ' + rowId);
});
});
</script>
Here is a working Fiddle

mix two toolbars in kendo grid

I have a kendo grid. I am using an add and custom button in the toolbar as the following code:
toolbar: ["create", {
text: "Print record",
className: "k-grid-custom",
imageClass: "k-add"
}],
I also want to add a custom toolbar (dropdown menu) as this example
I used similar code in the demo like
toolbar: kendo.template($("#toolbarIsExpire").html()),
<script type="text/x-kendo-template" id="toolbarIsExpire">
<div class="toolbar">
<label for="is_expired">Is Expired ?</label>
<input type="search" id="is_expired" style="width: 75px;"/>
</div>
</script>
I want to show in the toolbar the add button and my custom button and the dropdown menu (IsExpired)
How to mix between the two toolbar in order to have both of them ?
Extend your template:
<script type="text/x-kendo-template" id="toolbarIsExpire">
<div class="toolbar">
<label for="is_expired">Is Expired ?</label>
<input type="search" id="is_expired" style="width: 75px;"/>
</div>
<a class="k-button k-button-icontext k-grid-add" href="#"><span class="k-icon k-add"> </span>Add new record</a>
</script>

Kendo mobile template styling/formatting not working

I am trying to use a template as shown below, the outcome is a view with all elements from the template on one line, even though i am using to separate the elements. Why does this not display properly? It seems that no matter what styling i do it still ends up a single line view.
UPDATE
The culprit is the kendo style sheet - kendo.mobile.all.min.css -
So the new question for a kendo expert is why does kendo handle input fields differently when they appear in a listview via a template than when they appear outside of a template?
An input field outside of a listview template gets this class
.km-ios .km-list input:not([type="button"]):not([type="submit"]):not([type="reset"]):not([type="image"]):not([type="checkbox"]):not([type="radio"]):not(.k-input):not(.k-button), .km-ios .km-list select:not([multiple]), .km-ios .km-list .k-dropdown-wrap, .km-ios .km-list textarea
Which results in no odd styling rules :) Normal text field view
An input field inside of the template gets this class
.km-root input:not([type="button"]):not([type="submit"]):not([type="reset"]):not([type="image"]):not([type="checkbox"]):not([type="radio"]):not(.k-input):not(.k-button), .km-root select:not([multiple]), .km-root .k-dropdown, .km-root textarea
which results in these rules being applied to it (making the field sit in a wierd spot and loose all normal field stlying ie border background etc.) Im not 100% sure which wrapper is causing this
appearance: none;
-moz-appearance: none;
-webkit-appearance: none;
font-size: 1.1rem;
color: #385487;
min-width: 6em;
border: 0;
padding: .4em;
outline: 0;
background:
transparent;
My work around is to give any text fields inside listview templates the class="k-input" which obviously excludes them from the above css -
<script src="kendo/js/jquery.min.js"></script>
<script src="kendo/js/kendo.mobile.min.js"></script>
<link href="kendo/styles/kendo.mobile.all.min.css" rel="stylesheet" />

ListView widgets are supposed to be applied to <ul> elements.
Try changing:
<div id="eventDetail"></div>
to:
<ul id="eventDetail"></ul>
Also with this bit of code:
$("#eventDetail").kendoMobileListView({
dataSource: dataSource,
template: kendo.template($("#eventDetail-template").html())
}).data("kendoMobileListView");
The .data() call on the end isn't doing anything here and can be removed, and also you can pass just the text string as the template. You don't need to call kendo.template() yourself. So you can change that to just:
$("#eventDetail").kendoMobileListView({
dataSource: dataSource,
template: $("#eventDetail-template").html()
});

submit form at each step using Jquery form wizard

I am using Jquery Form wizard plugin in a MVC application. http://thecodemine.org/
I have a form with 4 steps. in one of step i have upload functionality.
I want submit functionality at each step and also back and next steps. later steps are optional.
I was able to add a submit button in navigation. On clicking it, form data related to active step is only submitted and other data is null.
For more clarity of my issue:
View :
<form id="myform" method="post" action="/Controller/Action">
<div id="fieldWrapper">
<fieldset class="step fieldset" id="first">
<legend class="legend">First step</legend>
Some input controls
</fieldset>
<fieldset class="step fieldset" id="second">
<legend class="legend">Second step</legend>
some more input controls (optional)
</fieldset>
<fieldset class="step fieldset" id="third">
<legend class="legend">Third step</legend>
some more input controls with filu upload
(optional)
</fieldset>
<fieldset class="step fieldset" id="fourth">
<legend class="legend">Fourth step</legend>
some more input controls (optional)
</fieldset>
</div>
<div id="demoNavigation">
<input class="navigation_button" id="back" value="Back" type="reset" />
<button type="submit" id="submitBtn">Submit and Finish</button>
<input class="navigation_button" id="next" value="Next" type="submit" />
</div>
</form>
Script:
<script type="text/javascript">
$(function () {
$("#myform").formwizard({
validationEnabled: true,
focusFirstInput: false,
disableUIStyles: true,
textSubmit: 'Submit and Finish',
textNext: 'Continue to next step',
next: "input:submit"
}
);
});
</script>
Updated the Jquery.form.wizard.js to so that the submit button hides at last step.
Now on each step i have submit button and navigation button.
When i submit form on second step, form data in second step is only posted and rest is not posted.
I went through the samples but could not find the appropriate one.
Can anyone suggest how to achieve this?
I went through the documentation and jquery.form.wizard.js file to get beeter understanding of what is done.
I just have to write some script as follows:
<script type="text/javascript">
$(function () {
$("#myform").formwizard({
validationEnabled: true,
focusFirstInput: false,
disableUIStyles: true,
textSubmit: 'Submit and Finish',
textNext: 'Continue to next step',
next: "input:submit"
}
);
});
$('#submitBtn').click(function () {
var stepInfo = $('#myform').formwizard('state');
for (var i = 0; i < stepInfo.activatedSteps.length; i++) {
stepInfo.steps.filter("#" + stepInfo.activatedSteps[i]).find(":input").not(".wizard-ignore").removeAttr("disabled");
}
});
</script>
