I'm trying to toggle the visible property of a Kendo UI window through the data-bind method using an MVVM pattern but it is not responding as it should according to the Kendo documentation.
<div id="KendoWindow"
data-role="window"
data-bind="visible:WindowVisible"
data-title="Title does not show"
data-width="500"
data-height="300"
>
<div class="span4" >
<label for="Comment">Comments</label>
<textarea id ="Comment" data-bind="value: Comment"></textarea>
</div>
I am initializing it properly but if I set the WinowVisible property to false in the viewModel like so,
this.set("WindowVisible", false);
the window stays visible.
If I set it through jQuery like so :
var dialog = $("#KendoWindow").data("kendoWindow");
dialog.setOptions({
visible:false
});
it will then become invisible. Then I can't make it visible again if I run this code:
var dialog = $("#KendoWindow").data("kendoWindow");
dialog.setOptions({
visible:true
});
Maybe try adding data-visible="false" to the window, then when the ShowWindow becomes true, it should become visible. I have a checkbox bound to the boolean value, as well as a button click function setting the boolean and both seem to work fine.

I am using Kendo UI MVC and i have a kendoTabStrip on acshtml page. By default I am selecting the first tab on page load. All other tabs are loaded dynamically using AJAX.
Issue: I am trying to find the selected tab so i can find its children?
one way to find active tab is by calling select() method without parameter, or anotherway is by checking classname 'k-state-active' however both methods doesnt work
<section class="tpt-tabstrip">
#(Html.Kendo().TabStrip()
.Name("MyTabStrip")
.Animation(false)
.Items(items =>
{
foreach (var revision in Model.MyCollection)
{
items.Add()
.Text(revision.Name)
.LoadContentFrom("MyActionMethod", "MyController", Model.ID);
}
})
)
</section>
<script src="~/Scripts/MyScript.js"></script>
Note that above in cshtml that the script tag is at the end of the page.
Below is the script code
$(function(){
var tabStrip = $("#MyTabStrip").getKendoTabStrip();
if (tabStrip != null && tabStrip.tabGroup.length > 0) {
tabStrip.select(0); // this line is getting executed for sure
}
// the line below returns -1 here why?????
var index = tabStrip.select().index();
// another way to find active tab is by checkikng class name 'k-state-active' however it didnt work either.
// jQuery couldnt find any element with class 'k-state-active'
$('.k-state-active')
})
UPDATE1
The activate event of tabstrip would not work for me because it get fired each time i select tab. I need an event which gets fired only once. Ultimately i want to find NumericTextBox controls on selected tab and attach 'change' event handlers to those controls. like below
$(function(){
var tabStrip = $('#MyTabStrip').data("kendoTabStrip");
tabStrip.bind('activate', function (e) {
$('[data-role="numerictextbox"]').each(function(){
$(this).getKendoNumericTextBox().bind("change",function(e){
alert('changed');
})
})
});
})
here the change event handler will get attach to NumericTextBox everytime i select the tab
$('.k-state-active') works fine it will return the two elements from DOM. You are trying to select element in $(document).ready that's the reason you are not getting element as tab control is not rendered yet.
Try to write your code onActivate event of kendo tab strip control.
OnActivate event is triggered after a tab is being made visible and its animation complete. Before Q2 2014 this event was invoked after tab show, but before the end of the animation. This event is triggered only for tabs with associated content.
See more at http://docs.telerik.com/kendo-ui/api/javascript/ui/tabstrip#events-activate
1st Tab name
<li class="k-item k-state-default k-first k-tab-on-top k-state-active" role="tab" aria-controls="RoleTabs-1" style="" aria-selected="true">
<span class="k-loading k-complete k-progress"></span>
<a class="k-link">Tab Name</a>
2nd Tab Content
<div class="k-content k-state-active" id="RoleTabs-1" style="display: block; height: auto; overflow: auto; opacity: 1;" role="tabpanel" aria-expanded="true">
I would like to have a button and when the user clicks on it a filter form pops down just below the button. I would like to utilize Kendo UI controls to achieve the effect.
In fact, what I need is almost exactly the 'filtering' that can be found on this example:
http://demos.telerik.com/kendo-ui/grid/filter-menu-customization
However, I'm not dealing with a grid of data so I can't use that example above.
There are different possible implementations. Here I will describe one based on kendoWindow since then you have a lot of possible customizations for that filtering form.
This is the HTML that includes the button:
<div>
This is the container that includes a
<button id="filter" class="k-button">Filter</button>
that is used to display a form
</div>
And then you define the HTML form. Example:
<div id="form">
<div>Filtering value:<input data-role="autocomplete"/></div>
<button class="k-button">Filter</button>
</div>
Doing the form initialization is:
var form = $("#form").kendoWindow({
title : "Filter",
visible : false,
modal : false,
draggable: false
}).data("kendoWindow");
Where initially we set the form as not visible.
You can define it as modal, draggable or even define the opening and closing effect.
Finally, for opening and placing the form just bellow the button you should:
$("#filter").on("click", function(e) {
// Find clicked button
var button = $(e.currentTarget);
// and get its position
var pos = button.offset();
// shift down the form to open by the height of the button + 5px (margin)
pos.top += button.outerHeight() + 5;
// Apply positioning to the form
form.wrapper.css(pos);
// display form
form.open();
});
You can see this here : http://jsfiddle.net/OnaBai/mpq6k/
I am using Angular UI Bootstrap to create a popover but I am unable to find the option to add a close button inside the popover.
I customized the popover template to include the close button. But I am still unable to find a function/event to close the popover. Setting isOpen to false works for the first time as it just overwrites the function - but thereafter becomes unusable.
<button popover-placement="bottom" popover="test">POPOVER WITH CLOSE<button>
Here is the template script:
angular.module("template/popover/popover.html", []).run(["$templateCache", function($templateCache) {
$templateCache.put("template/popover/popover.html",
"<div class=\"popover {{placement}}\" ng-class=\"{ in: isOpen(), fade: animation() }\">\n" +
" <div class=\"arrow\"></div>\n" +
"\n" +
" <div class=\"popover-inner\">\n" +
" <button ng-click=\"isOpen = !isOpen()\" class=\"btn-popover-close btn btn-primary\">Close</button>\n" +
" <h3 class=\"popover-title\" ng-bind=\"title\" ng-show=\"title\"></h3>\n" +
" <div class=\"popover-content\" ng-bind=\"content\"></div>\n" +
" </div>\n" +
"</div>\n" +
"");
}]);
I thought of writing a directive for close button to trigger the 'click" event of "POPOVER WITH CLOSE" button. But I am not sure if that's the approach to follow.
What's the correct approach to follow?
The right solution now is to specify a popover template via the uib-popover-template attribute and bind your template's close button's ng-click handler to the popover's popover-is-open property. We added this property to allow the user to "ignore" the provided trigger options (by specifying popover-trigger="none" and give the user full control over when to show and hide the popover.
You may see the updated docs (and examples) here.
I changed the tooltip and popover code.
Here is how it looks like plunker
Here is the pull request for this.
Setup
I've got a Telerik Kendo UI TabStrip with multiple tabs inside of an UpdatePanel...
<asp:UpdatePanel ID="DataDetails_Panel" UpdateMode="Conditional" runat="server">
<div id="ABIOptions_TabContainer">
<ul>
<li>Attendance</li>
<li>Grades</li>
<li>Gradebook</li>
<li>PFT</li>
<li>Scheduling</li>
<li>Miscellaneous</li>
<li>Parent Data Changing</li>
</ul>
</div>
</asp:UpdatePanel>
...which I then wire up in javascript later...
var optionTabContainer = $("#ABIOptions_TabContainer").kendoTabStrip({
animation: {
open: {
effects: "fadeIn"
}
},
select: onMainTabSelect
}).data("kendoTabStrip");
Scenario
The users will click on the various tabs and inside of each tab are settings for our portal. When they are in a tab and they make a change to a setting, the expectation is that they'll click on the 'Save' button, which will perform a postback to the server via ajax, because it is in the update panel.
Current Behavior
After the post back happens and the ul content comes back, I reapply the kendoTabStrip setup function call, which makes none of the tabs selected. This appears to the user like the page is now empty, when it just had content.
Desired Result
What I want to do, is after the partial postback happens and the UpdatePanel sends back the ul, I want to reselect the tab that the user previously selected.
What Already Works
I already have a way to preserve the tab that the user clicked on:
var onMainTabSelect = function (e) {
tabToSelect = e.item;
console.log("onTabSelect --> ", e.item.textContent);
}
and a function to reset the selected tab whenever it is called:
function setMainTab() {
if (!jQuery.isEmptyObject(tabToSelect)) {
var tabStrip = $('#ABIOptions_TabContainer').data("kendoTabStrip");
console.log("Attempt to set tab to ", tabToSelect.textContent);
tabStrip.select(tabToSelect);
} else {
console.log("tabToSelect was empty");
}
}
What Doesn't Work
My hypothesis is that the Kendo TabStrip says, "Hey, that tab is already selected" when I call the setMainTab after my postback:
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
BindControlEvents();
setMainTab();
});
...and therefore, doesn't set my tab back. If I click on the tab, then Poof, all my content is there just like I expect.
Any ideas what I may be doing wrong?
I ended up changing the onMainTabSelect method to:
var onMainTabSelect = function (e) {
tabToSelect = $(e.item).data("tabindex");
}
which gets me the data-tabindex value for each li in my ul. I couldn't get the tab index from kendo, so I had to role my own. Once I got that value, then I was able to set the selected tab via an index rather than the tab object reference itself.
I need to create a jQuery App with 30 buttons, from 1 to 30, whereby each one calls the exact same action script via Ajax where the parameter that is passed to the action script is simply the number of the button pressed (1 to 30).
For example, let's say the action script is process.php, if button 3 is pressed, then I need to pull data from process.php?btn=3, and if button 27 is pressed, then I need to pull data from process.php?btn=27.
Which type of button should I use for this: <input> buttons, <a> buttons, <button> buttons, or something else? And why do you suggest that?
Also, how would Ajax get the corresponding value (1-30) of the button pressed with the method you suggest?
Thanks!
I would suggest to use <a/> that way if JavaScript is disabled you can maintain the application's functionality.
Button 3
And the script would simply use the href to post to your page.
$("a.actionButton").click(function(e){
e.preventDefault();
$.post(this.href, {}, function(data){
//do something with the data.
});
});
Update
Since JavaScript is required than my recommendation would depend on your application design. If you want the big buttons to look like buttons simply use <input type="button" value="3"/> As by default they will have hover effect, depressed effect built out of the box.
If your buttons do not look like normal buttons maybe just blocks or some other style a <div/> could also be an option. The one downside to using an <a/> would be you always have to suppress the default behavior of the click()
Each will work fine. But the <a> you can style with an image while <input> and <button> you cannot (the browser decides on the look).
Simply bind the click event on the button. Assuming you have this HTML:
Button 1
Button 2
...
Button 3
Here's the Javascript. The trick is to call the AJAX here, and return false to prevent the Browser from changing page.
$('a').click(function(e) {
$.get($(this).attr('href'), function(result) {
alert('AJAX result = '+result);
});
return false;
});
You could create a custom attribute on each button.
<input type="button" onclick="YourCallbackMethod(this)" buttonNumber="1" value="Button 1" />
In your javascript
function YourCallbackMethod(button)
{
var number = $(button).attr("buttonNumber");
// Call the ajax method with the number value.
}
By doing this you can add additional attributes to extend the data stored in each button and it also makes chaning the AJAX target link very easy since it's centralised, rather than spread around multiple anchor tags.
As an alternative to Marks answer, you could use a <form> element, and have each button a submit button; either a input or button. Set the name of the element to "btn" and the value of the element to the button number.
<form id="foo" action="process.php" method="<!-- POST or GET? -->">
<button type="submit" name="btn" value="1">Button 1</button>
</form>
The jQuery would look something like:
jQuery(document).ready(function ($) {
$('#foo').bind('submit', function (evt) {
jQuery.ajax({
url: this.action,
data: $(this).serialize(),
success: function () {
// whatever
}
});
evt.preventDefault();
});
});
If you want the submission to be a POST request, this would most likely be better. For a GET request however, Marks will probably be easier.
