Kendo UI Grid - Custom command button disabled depending on boolean property - javascript

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>

Binding array of object to Kendo grid popup multiselect

I'm trying to bind an array of id-value pairs to a kendo grid popup editor.
Got everything to work for creating a new record. Popup editor loads the custom editor and successfully submits the data to the controller.
The problem is when I try to edit records. The records displays properly in the row, but when I try to edit it, the multiselect does not hold the values.
Grid Markup
$("#ProjectSites-SubContract-grid").kendoGrid({
dataSource: {
type: "json",
schema: {
data: "Data",
total: "Total",
errors: "Errors",
model: {
id: "Id",
fields: {
DateOfContract: { type: 'date', editable: true },
DateOfCompletion: { type: 'date', editable: true },
AmountOfContract: { type: 'number', editable: true },
Contractor: { defaultValue: { id: "", name: "" } }
}
}
},
},
columns: [
{
field: "ScopeOfWork",
title: "Scope of Work",
template: "#=parseScopeOfWork(ScopeOfWork)#",
editor: scopeOfWorkEditor
},
]
});
});
Scope of Work editor
function scopeOfWorkEditor(container, options) {
$('<input data-text-field="name" data-value-field="id" data-bind="value:ScopeOfWork"/>')
.appendTo(container)
.kendoMultiSelect({
dataSource: {
data: [
#foreach (var scopeOfWork in Model.AvailableScopeOfWork)
{
<text>{ id : "#scopeOfWork.Value", name : "#scopeOfWork.Text" },</text>
},
]
}
});
parseScopeOfWork -
this method guys iterates through the object list and concats the name.
function parseScopeOfWork(scopeOfWork) {
var result = "";
for (var i = 0; i < scopeOfWork.length; i++) {
result += scopeOfWork[i].Name;
if (i < scopeOfWork.length - 1)
{
result += ", <br/>";
}
}
return result;
}
Here's a screenshot:
You're binding the SpaceOfWork to the new widget, but how that widget knows your Model ? I mean, just using data-bind doens't binds the model to the widget, it can't figure that by itself. I have two suggestions:
Set the value in the widget's initialization:
.kendoMultiSelect({
value: options.model.ScopeOfWork
Demo
Bind the model to the widget for good:
let $multiSelect = $('<input data-text-field="name" data-value-field="id" data-bind="value:ScopeOfWork"/>');
kendo.bind($multiSelect, options.model);
$multiSelect
.appendTo(container)
.kendoMultiSelect({ ...

jquery DataTables Editor: "select" field displays option value instead of label

I am using jquery's DataTables which is really working great. Then only problem I got is, that I am facing (in non-edit-view) the value of the select-field (which is an id). The user of course doesn't want to see the id of course.
Therefore I am looking for a possibility to configure that column in a way to show always the value of label property.
Here a some snippets:
$(document).ready(function() {
var table = $('#overviewTable').DataTable({
dom: "Tfrtip",
ajax: "/Conroller/GetTableData",
columns: [
{ data: "Id", className: "readOnly", visible: false },
{
data: "LoanTransactionId",
className: "readOnly readData clickable",
"fnCreatedCell": function(nTd, sData, oData, iRow, iCol) {
$(nTd).html("<a href='#'>" + oData.LoanTransactionId + "</a>");
}
},
{ data: "Id", className: "readOnly" },
{ data: "property_1", className: "readOnly" },
{ data: "Priority" },
{ data: null, className: "action readOnly", defaultContent: 'Info' }
],
order: [1, 'asc'],
tableTools: {
sRowSelect: "os",
sRowSelector: 'td:first-child',
aButtons: []
}
});
// data reload every 30 seconds
setInterval(function() {
table.ajax.reload();
}, 30000);
editor = new $.fn.dataTable.Editor({
ajax: "PostTable",
table: "#overviewTable",
fields: [
{
label: "Id",
name: "Id"
},
{
label: "Column 1",
name: "property_1"
},
{
label: "Priority",
name: "Priority",
type: "select",
options: [
{ label: "low", value: 0 },
{ label: "mid", id: 1 },
{ text: "high", id: 2 }
]
}
]
});
// Inline Edit - only those who are not readOnly
$('#overviewTable').on('click', 'tbody td:not(:first-child .readOnly)', function(e) {
editor.inline(this, {
submitOnBlur: true
});
});
How it looks in the display mode
How it looks in the edit mode
See the documentation on columns.render
You want to modify your column options for priority
Preferred Option: Your data source has a field with the priority as a string
This is the best option, as you don't want to have two places with this business logic. Keep it out of the client code.
Also, you will want to modify the editor as well so that the options used have been retrieved dynamically from the server to keep this business logic out of the client too. This is left as an exercise for the reader.
Since you don't provide details on what your data structure looks lik, I'm assuming it is an object, and it has an attribute priorityAsString so use the string option type for render.
columns: [
...
{
data: "Priority" ,
render: "priorityAsString",
},
Option 2) You write a function to map priority to string
Do this if you can't get the data from the server. But remember you will need to update many places when the priority list changes.
columns: [
...
{
data: "Priority" ,
render: renderPriorityAsString,
},
...
function renderPriorityAsString(priority) {
const priorityToString = {
0: 'low',
1: 'med',
2: 'high',
};
return priorityToString[priority] || `${priority} does not have a lookup value`;
}
"render": function ( data, type, full ) { return label;}

How to make "add new record" represent field as checkbox - Kendo Grid

I am trying to add a new record to a kendo grid (only using client side javascript) and I can only get all the fields represented as text fields.
One of the fields however is actually a boolean and I would like it to be represented as a check box instead. Does anyone know how to do this?
Can anyone please help? Any help would be greatly appreciated.
UPDATED with code below. Also I tried the template suggestion but this is not working when I click on the Add New Record button at the top of the grid. I get a JavaScript error "primary is not defined"
$("#phoneGrid").kendoGrid({
columns: [
{
field: "type",
title: "Type"
},
{
field: "primary",
title: "Primary",
template: "<input type=\"checkbox\" #= primary ? checked='checked' : '' #/>"
},
{
field: "number",
title: "Number"
},
{ command: ['edit'], title: ' ' }
],
editable: "inline",
dataSource: {
data: patientDetailUpdateViewModel.phones,
schema: {
model: { id: "id" }
}
},
toolbar: ['create'],
save: function (e) {
//alert("Save Event Triggered");
if (e.model.isNew()) {
phone = new Phone();
//Give the phone an id to uniquely identify it, but one which would signify a new phone instance (negative phone instance).
phone.id = patientDetailUpdateViewModel.phones.length * -1;
e.model.id = phone.id;//So isNew() will return false on subsequent calls.
phone.type = e.model.type;
phone.primary = e.model.primary;
phone.number = e.model.number;
patientDetailUpdateViewModel.phones.push(phone);
//alert("isNew() = true");
}
}
});
You can use template for column definition:
{
field: "ColumName",
template: '<input type="checkbox" #= Column? checked="checked" : "" # disabled="disabled" ></input>'
}
EDIT:
Try to define data source model (http://docs.telerik.com/kendo-ui/api/javascript/data/datasource#configuration-schema.model) like below, but according to your data types in source:
schema: {
model: {
id: "ProductID",
fields: {
type: {
type: "string"
},
UnitPrice: {
type: "number"
}
}
}
}

How to dynamically add and remove GROUPS to KendoUI Scheduler

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

KendoUI Grid Custom Filter UI

I am trying to implement a custom filter UI with a drop down box with some dummy data for now. I have followed the tutorial on the Kendo site (http://demos.kendoui.com/web/grid/filter-menu-customization.html) but it just isn't working for me :(.
Here is the function for the custom UI:
function relStatFilter(element)
{
element.kendoDropDownList({
dataSource: ["Prospect", "Customer"],
optionLabel: 'Select status'
})
}
And here is the column parameters it's being applied to:
...
{
field: 'relStat',
filterable:
{
ui: relStatFilter,
extra: false
},
title: '<abbr title=\'Relationship status\'>Rel stat</abbr>',
template: '#= ratio == 0 ? "<span class=text-info>Prospect</span>" : relStat == "Active" ? "<span class=text-success>Active</span>" : relStat == "At risk" ? "<span class=text-warning>At risk</span>" : "" #',
},
...
When I click the filter all I get is the standard "starts with" and the text input.
What have I missed?
Custom filtering UI is available since 2012.3.1315. Make sure you are not using an older version. Using 2012.3.1315 the following code works as expected:
$("#grid").kendoGrid({
dataSource: [ { name: "Foo" }, { name: "Bar" }],
filterable: {
extra: false,
operators: {
string: {
eq: "Is equal to",
neq: "Is not equal to"
}
}
},
columns: [
{
field: "name",
filterable: {
ui: function(element) {
element.kendoDropDownList({
dataSource: [ "Foo", "Bar"]
});
}
}
}
]
});
