Need help here. I create a simple demo here and what I want to achieve from dataBound if checked='yes' node is selected and disable(apply k-state-disable) from edit. I try to set (selected,true) & (disabled,true) but seem it not working.
DEMO IN DOJO
<select id="multiselect"></select>
$("#multiselect").kendoMultiSelect({
dataSource: {
data: [
{id:1, Name: "John 1", checked: 'no'},
{id:2, Name: "John 2", checked: 'yes'},
{id:3, Name: "John 3", checked: 'no'},
{id:4, Name: "John 4", checked: 'yes'},
{id:5, Name: "John 5", checked: 'no'},
{id:6, Name: "John 6", checked: 'no'}
]
},
dataTextField: "Name",
dataValueField: "id",
dataBound: function(e) {
var multiselect = $("#multiselect").data("kendoMultiSelect");
var x = multiselect.dataSource.view();
for (var i = 0; i < x.length; i++) {
if (x[i].checked == "yes") {
//x[i].set("selected", true);
//x[i].set("disabled ", true);
//x[i].prop("disabled", true).addClass("k-state-disabled");
}
}
},
});
I want to suggest another way for achieve that. Avoid changing DOM in dataBound whenever possible. So I would like to suggest using itemTemplate option and select event:
You can apply .k-state-disabled class within the itemTemplate option:
itemTemplate: '<span # if (data.checked === "yes") { #class="k-state-disabled"# } #>#: Name #</span>'
That will make the option look like disabled. But it is still possible to select it in the list, so you can use select event to prevent that:
select: function(e) {
if (e.dataItem.checked === 'yes') {
e.preventDefault();
}
},
Using e.preventDefault() inside that event will prevent user from selecting the option which matches the condition.
Updated Demo
You need to handle select and deselect events:
function onDeselect(e) {
if (e.dataItem.checked == 'yes') {
e.preventDefault();
}
}
function onSelect(e) {
if(e.dataItem.checked == 'yes') {
e.preventDefault();
}
};
$("#multiselect").kendoMultiSelect({
select: onSelect,
deselect: onDeselect,
//...
});

How can I set the class to disabled for a custom command on a Kendo grid depending on the boolean value of a property?
I want to use this approach to make the button disabled:
https://docs.telerik.com/kendo-ui/knowledge-base/disable-the-grid-command-buttons
Javascript:
{ command: { name: "custom", text: "Exclude", click: excludeCategorization }, title: " ", width: "60px" }
I want to add a condition like this using the property IsEnabled but if possible using the k-state-disabled class
#= IsEnabled ? disabled="disabled" : "" #
I don't believe you can assign classes conditionally through a template, however you can use the dataBound event to crawl through the rows and manipulate the classes. I would start with all of them disabled and then enable the ones that need to be active, but you can build your own logic. Here's an example:
<div id="grid"></div>
<script>
var grid;
$("#grid").kendoGrid({
dataBound:function(e){
var grid = $("#grid").data("kendoGrid");
var items = e.sender.items();
items.each(function (index) {
var dataItem = grid.dataItem(this);
$("tr[data-uid='" + dataItem.uid + "']").find(".excludeCategorization").each(function( index ) {
if(dataItem.isEnabled)
{
$(this).removeClass('k-state-disabled')
}
});
})
},
columns: [
{ field: "name" },
{ field: "enabled" },
{ command: [{ className: "k-state-disabled excludeCategorization", name: "destroy", text: "Remove" },{ className: "k-state-disabled", name: "edit", text: "Edit" }] }
],
editable: true,
dataSource: [ { name: "Jane Doe", isEnabled: false },{ name: "John Smith", isEnabled: true } ]
});
</script>

I have recently started learning KendoUI and have come up with this issue. I am trying to include a dropdownlist in kendo grid using MVVM approach. The grid has 3 columns- Checkbox, text and dropdownlist. I want to manually set the dropdownlist value based on whether the checkbox is checked or not. As an example here i am trying to set the Class as 'Class 3' if checkbox is unchecked. Even though index is set to 2, it gets reverted back to the class from the model at the end of the event dataBound. Can anyone help me with this? I need to forcefully set the dropdown index. Thank you.

I'm working on bootstrap-multiselect, I'm trying to add data attributes in the dataprovider method.
Current
var options = [
{label: 'Option 1', title: 'Option 1', value: '1', selected: true},
{label: 'Option 2', title: 'Option 2', value: '2'}];
In the code it maps these an <option> tag like so:
$tag = $('<option/>').attr({
value: option.value,
label: option.label || option.value,
title: option.title,
selected: !!option.selected,
disabled: !!option.disabled
});
Desired
var options =[
{
"label": "Item 1",
"value": 1,
"selected": false,
"attributes": [
{
"some-attribute": 10001
},
{
"another-attribute": "false"
}
]
}
]
So it will render on the HTML element as data-some-attribute="10001" data-another-attribute="false".
I started out adding this to the code (which I know won't work):
$tag = $('<option/>').attr({
value: option.value,
label: option.label || option.value,
title: option.title,
selected: !!option.selected,
disabled: !!option.disabled,
forEach(option.attributes, function(attribute){
})
});
The problem of course is you can't add a loop as an objects properties.
Once this is working I can add a pull request to the repository. I did ask a question on the repo but decided to try and tackle it myself Issue #592
Any ideas?
I would suggest changing attributes from an array to an object, since attribute names should be unique. It also simplifies how you would get the data attributes on the element.
var attributes = {
value: option.value,
label: option.label || option.value,
title: option.title,
selected: !!option.selected,
disabled: !!option.disabled
};
for (key in option.attributes) {
attributes['data-' + key] = option.attributes[key];
}
$tag = $('<option/>').attr(attributes);
If you wanted to keep it as an array, you can do the following:
var attributes = {
value: option.value,
label: option.label || option.value,
title: option.title,
selected: !!option.selected,
disabled: !!option.disabled
};
for (var i = 0; i < option.attributes.length; i++) {
var key = Object.keys(option.attributes[i])[0],
val = option.attributes[i][key];
attributes['data-' + key] = val;
}
$tag = $('<option/>').attr(attributes);
Doing this, however, provides no benefit and introduces complexity. If each object can have multiple keys, the code will need to change further.
You need to create the element first then add the attributes to it.
So your code should be like this:
var options = [{
"label": "Item 1",
"value": 1,
"selected": false,
"attributes": [{
"some-attribute": 10001
}, {
"another-attribute": "false"
}]
}]
console.log(options.length);
$.each(options, function(option) {
var $tag = $('<option/>').attr({
value: options[option].value,
label: options[option].label || options[option].value,
title: options[option].title,
selected: options[option].selected,
disabled: options[option].disabled
});
console.dir(option);
$.each(options[option].attributes, function(att) {
$tag.attr("data" + Object.keys(att)[0], att[0])
});
$("#mySelect").append($tag);
});

I need to use image drop-down list from http://designwithpc.com/plugins/ddslick I am trying to set "selected" option after postback, but I get infinite loop of postbacks. Here is my code:

</form>
<script type="text/javascript">
//Dropdown plugin data

}
}
});
</script>
Could please help me to solve it?
Calling:
$( '#demoSetSelected' ).ddslick( 'select', { index: i } );
will also trigger the "onSelected()" function you defined causing an infinite loop.
I solved the same problem by modifying the source file (jquery.ddslick.js) and adding a flag to disable the call to onSelected():
Change the select function to:
methods.select = function (options) {
return this.each(function () {
if (options.index)
selectIndex($(this), options.index, options.disableTrigger);
});
}
Modify selectIndex function definition from:
function selectIndex(obj, index) {
to:
function selectIndex(obj, index, disableTrigger) {
At the very end of the function selectIndex(...), change from:
if (typeof settings.onSelected == 'function') {
settings.onSelected.call(this, pluginData);
}
to:
if ( !disableTrigger ) {
if (typeof settings.onSelected == 'function') {
settings.onSelected.call(this, pluginData);
}
}
Then use instead:
$( '#demoSetSelected' ).ddslick( 'select', { index: i, disableTrigger: true } );
As an aside: to select by value instead of index, check out the code mentioned in:
https://github.com/prashantchaudhary/ddslick/issues/78
https://github.com/lunrfarsde/ddslick
It's a fork of dd-slick with the description part removed. But added select by value.
You may use plugin's select method like
$('#demoSetSelected').ddslick('select', {index: i });
to select a particular index.
As per ddSlick demo#4 on their website(http://designwithpc.com/plugins/ddslick#demo)
I am using KendoUI Scheduler control and here is initialization code
$("#Scheduler").kendoScheduler({
dataSource: [],
selectable: true,
height: 500,
editable: false,
eventTemplate: $("#event-template").html(),
views: [
"day",
{ type: "week", selected: true },
"month",
"agenda"
],
resources: [
{
field: "resourceviewid",
name: "ResourceViews",
dataColorField: "key",
dataSource: [
{ text: "Appointments", value: 1, key: "orange" },
{ text: "Delivery Specialist", value: 2, key: "blue" },
{ text: "Orientation Specialist", value: 3, key: "green" }
]
}
],
group: {
resources: ["ResourceViews"],
orientation: "horizontal"
}
});
Here "Appointments" group is default, it will be available always
I have check box in my screen
<div id="divResourceView">
<label><input checked type="checkbox" value="1" />Delivery Specialist</label>
<label><input checked type="checkbox" value="2" />Orientation Specialist</label>
</div>
On change event I wrote below code to get selected values from checkbox and updating GROUP datasource of KendoUI scheduler as below
$("#divResourceView :checkbox").change(function (e) {
var checked = $.map($("#divResourceView :checked"), function (checkbox) {
return parseInt($(checkbox).val());
});
});
var scheduler = $("#Scheduler").data("kendoScheduler");
var arrayOfStrings = checked.toString().split(",");
for (var i = 0; i < arrayOfStrings.length; i++)
{
if(arrayOfStrings[i] == 1)
{
var data = [{ text: "Delivery Specialist", value: 2, color: "blue" }];
scheduler.resources[1].dataSource.data(data);
}
if (arrayOfStrings[i] == 2) {
var data = [{ text: "Orientation Specialist", value: 3, color: "green" }];
scheduler.resources[2].dataSource.data(data);
}
}
scheduler.refresh();
But it removes all groups and add only one. I want to see both groups when arrayOfStrings has values "1,2",
I can see all groups during initialization But it disappears when i check the check box.
Images for reference
During Initialization
After
As you can see clearly, Delivery Specialist is missing in scheduler control
Found some link: http://www.telerik.com/forums/add-filter-to-resource-datasource
But not sure what they talking about? seems like refresh issue.
I have done this I believe you're right and your issue is to do with refreshing, I use the following to refresh it.
var scheduler = $("#scheduler").data("kendoScheduler");
scheduler.view(scheduler.view().name);
hope this helps through it is stupidly late (I'm currently looking up how to do this lazerly
