show / hide columns menu placed in one place

I'm building a table with large number of columns which I want to be able to show and hide from user menu.
As the example I can use this

http://demos.kendoui.com/web/grid/column-menu.html

My problem is that show/hide menu is the same for all columns, but it is buried deep inside column menu of each individual column.
I want to have that menu only in one place, possibly in table toolbar or exposed in footer so the user does not need to click through the complex dropdowns.

Upgrading to iOS7: Tabstrip displays random icons! Help

Hello team

After replacing the .css and the .js files with the latest KendoUI Mobile - and installing on my iOS7 device, the tabstrip icons, and data-icons for various menus within my application have mucked up. Instead of the data-icon "home" , the data-icon "search" pictures, I get random pictures, like a love heart, a spade, a number 3 in a box, an angel.. etc... is there something I have missed? Do I have to explicitly define images now?

Thankyou.

Regards

[Solved] "Add New" option

We're using this control for tags and we want to let them select an existing tag or add a new tag.

What's the recommended approach for adding an option to the list such as "Add New" that uses the currently entered text to create a new item?

Checkbox events not firing the second time.

Hi,

I have a TreeView for a filter on a dashboard, and it's not processing the click on the checkbox the second time. I've attached a screen shot with more details.

I'm not sure what I have wrong.
Creating the TreeView:

/* Topics illustrated in this file:

* How to define a custom widget

* How to configure options from base

* How to define and access custom options

* How to capture scope

* How to manipulate the DOM of "this"

* How to expose custom methods

* How to expose an event handler delegate

*/

define([

'jquery',

'underscore',

'utils/helpers',

'text!views/schoolFilterItem.html',

'kendoui/kendo.treeview.min',

], function ($, _, Helpers, schoolFilterItemTemplate) {

var schoolData;

// This defines a Kendo widget object

var TreeView = kendo.ui.TreeView.extend({

init: function (element, options) {

// Assigning this to another variable name captures the context of init, which is "this TreeView"

var me = this;

options.dataSource = {

transport: {

read: function (options) {

$.getJSON(Helpers.toServicesUrl("/GetfltSchoolByDistrict"),

{

// If you tried to use "this" in here, it would refer to the dataSource instead of the TreeView

userName: me.options.userName,

districtId: me.options.districtId,

schoolCodes: me.options.schoolCodes

},

function (data) {

options.success([]);

schoolData = data.GetfltSchoolByDistrictResult.RootResults;

schoolData = [

{

text: "Schools",

}

];

me.dataSource.data(schoolData);

schema: {

model: {

children: "items"

}

};

options.dataBound = function (e) {

me.element.find("input:checkbox:first").prop("disabled", true);

me.element.find("input:checkbox").on("change", function (e) {

var parentItems = $(e.target).parents(".k-item");

var node = parentItems.eq(0);

var parentNode = parentItems.eq(1);

// Toggle children to match parent

node.find("input:checkbox").prop("checked", e.target.checked);

// Update parent's state

var parentCheckBox = parentNode.find("input:checkbox:first");

if (!parentCheckBox.prop("disabled")) {

var hasChecked = parentNode.find(".k-group input:checked").length > 0;

var hasUnchecked = parentNode.find(".k-group input:not(:checked)").length > 0;

// The rest is unchecking other SchoolTypes if a different SchoolType is checked. If "this" is unchecked, no further action required.

if (!e.target.checked)

return;

var dataItem = me.dataItem(node);

if (!dataItem.SchoolTypeName) {

e.target.checked = false;

return;

}

me.element.find("input:checked").each(function () {

var eachDataItem = me.dataItem($(this).closest(".k-item"))

if (eachDataItem.SchoolTypeName !== dataItem.SchoolTypeName) {

this.checked = false;

this.indeterminate = false;

//lah testing adding something here.

// me.schoolTypeChanged(e);

me.onSchoolChange(e);

}

//gmo when school names don't match

if (eachDataItem.SchoolName !== dataItem.SchoolName) {

this.checked = false;

me.onSchoolChange(e);

}

});

}

kendo.ui.TreeView.fn.init.call(this, element, options);

},

options: {

// This is what determines the name of the custom method, e.g. .kendoSchoolFilterTreeView

name: "TreeViewSchoolFilterSingle",

// Declare new options with default values. Options must be declared here in order to be accepted and passed through to init().

userName: "",

districtId: 0,

schoolCodes: function () { return "" },

// Anything else you pass in options will get passed to the base widget

dataTextField: ["text", "SchoolTypeName", "SchoolName"],

checkboxes: true

},

getSelectedSchoolType: function () {

var me = this;

return _(this.element.find("input:checked").closest(".k-item"))

.chain()

//                                              .map(function (item) { return ktvSchoolFilter.dataItem(item).SchoolType; })

.map(function (item) { return me.dataItem(item).SchoolType; })

.filter(function (item) { return item; })

.value()[0];

},

// This is how to get the selected school from the radio group

getSelectedSchoolCodes: function () {

.chain()

//                                              .map(function (item) { return ktvSchoolFilter.dataItem(item).SchoolCode; })

.value()

.join(",");

},

onSchoolChange: function (e) {

return;

},

schoolTypeChanged: function (e) {

return;

}

});

// This is what registers the custom widget and adds the kendo* method to the jQuery object

kendo.ui.plugin(TreeView);

});

How it's used in my program, including several variations on binding.

ktvSchoolFilter = $("#schoolFilterTree").kendoTreeViewSchoolFilterSingle({

userName: WSIPCContext.UserName,

districtId: WSIPCContext.DistrictId,

schoolCodes: WSIPCContext.SchoolCodes,

onSchoolChange: schoolCodeChanged,

change: schoolCodeChanged,

schoolTypeChanged: schoolCodeChanged,

checkbox: {

onClick: schoolCodeChanged

}

}).data("kendoTreeViewSchoolFilterSingle");

//This code allows the grade level and risk categories to change when a checkbox

//is selected, not just the label.

ktvSchoolFilter.dataSource.bind("change", schoolCodeChanged);

ktvSchoolFilter.dataSource.bind("select", schoolCodeChanged);

ktvSchoolFilter.dataSource.bind("selecting", schoolCodeChanged);

ktvSchoolFilter.dataSource.bind("navigate", schoolCodeChanged);

ktvSchoolFilter.bind("change", schoolCodeChanged);

ktvSchoolFilter.bind("select", schoolCodeChanged);

ktvSchoolFilter.bind("selecting", schoolCodeChanged);

ktvSchoolFilter.bind("navigate", schoolCodeChanged

[Solved] Set cancel option on a grid that has already been initialized

Is there a way to set the cancel option on a grid that has already been initialized?

I'm using the serverside MVC wrapper and have this:
.Events(events => events.Cancel("function() {alert('hi');}"))

Clientside I tried:
$("#grdTest").kendoGrid({ cancel: function () { alert("canceled"); } });
and
$kendoGrid = $("#grdTest").data("kendoGrid");
$kendoGrid.options.cancel = function () {
alert('Canceled');
};

Editor removes src attribute in IE8

I'm using the javascript version of the KendoUI Editor. I've tried loading the editor with this in the text field:
<img src="someimagehere.png" alt="" />

After the editor loads, the html says the field has this:
<img alt="" />

This only happens when I'm working in IE8. What's happening?
