How to set cutom template for kendo grid columns

I need to set Kendo grid action button Icon based on value. My code as follows,
function InitProductServicesGrid() {
var prodServiceDataSource = new kendo.data.DataSource({
transport: {
type: "json",
read:
{
url: SERVER_PATH + "/LTSService/ProductsService.asmx/GetProductServiceDetailsList",
type: "POST",
contentType: 'application/json',
data: GetAdditonalData,
datatype: "json"
},
update:
{
url: SERVER_PATH + "/LTSService/ProductsService.asmx/SaveProductService",
type: "POST",
contentType: 'application/json',
datatype: "json"
}
},
schema: {
data: function (result) {
return JSON.parse(result.d);
},
model: {
id: "Id",
fields: {
Id: { type: "int" },
ServiceTime: { type: "string" },
IsActive: { type: "boolean"}
}
}
},
requestEnd: function (e) {
if (e.type === "destroy") {
var grid = $("#productServicesGrid").data("kendoGrid");
grid.dataSource.read();
}
},
error: function (e) {
e.preventDefault();
if (e.xhr !== undefined && e.xhr !== null) {
var messageBody = e.xhr.responseJSON.Message;
ShowGritterMessage("Errors", messageBody, false, '../App_Themes/Default/LtsImages/errorMessageIcon_large.png');
var grid = $("#productServicesGrid").data("kendoGrid");
grid.cancelChanges();
}
},
pageSize: 20,
});
$("#productServicesGrid").kendoGrid({
dataSource: prodServiceDataSource,
sortable: true,
filterable: false,
pageable: true,
dataBound: gridDataBound,
editable: {
mode: "inline",
confirmation: false
},
columns: [
{ field: "Id", title: "", hidden: true },
{
field: "ServiceTime",
title: "Time Standard",
sortable: false,
editor: function (container, options) {
var serviceTimeTxtBox = RenderServiceTime();
$(serviceTimeTxtBox).appendTo(container);
},
headerTemplate: '<a class="k-link" href="#" title="Time Standard">Time Standard</a>'
},
{
title: "Action", command: [
{
name: "hideRow",
click: hideRow,
template: comandTemplate
}
],
width: "150px"
}
]
});
}
I wrote a custom template function as follows,
function comandTemplate(model) {
if (model.IsActive == true) {
return '<a title="Hide" class="k-grid-hideRow k-button"><span class="k-icon k-i-lock"></span></a><a title="Hide"></a>';
}
else {
return '<a title="Show" class="k-grid-hideRow k-button"><span class="k-icon k-i-unlock"></span></a><a title="Show"></a>';
}
}
But when I debug the I saw the following value for model value.
I followed this sample code as well. here you can see, I also set the custom template like the sample code. Please help me to solve this. Why I can't access model IsActive value from comandTemplate function.
Updated
When clicking hideRow action, I access the dataItem as follows.
function hideRow(e) {
e.preventDefault();
var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
if (dataItem.IsActive == true) {
dataItem.IsActive = false;
}
else {
dataItem.IsActive = true;
}
}
Is there any possible way to access data from template function as above or any other way?

I would suggest a different approach because you can't access grid data while rendering and populating grid.
My suggestion is to use two actions and hide it based on the flag (in your case IsActive).
Something like this: Custom command
NOTE: in visible function you can access item!
EDIT: you can access it and change it on dataBound traversing through all data.
Check this example: Data bound

I don't see the advantage of relying on the grid commands. You can render any button you want yourself and and use the dataBound event to bind a click handler:
$("#grid").kendoGrid({
columns: [
{ field: "name" },
{
template: function(dataItem) {
const isActive = dataItem.isActive;
return `<a title=${isActive ? "Hide": "Show"} class="k-grid-hideRow k-button"><span class="k-icon k-i-${isActive ? 'lock' : 'unlock'}"></span></a>`
}
}
],
dataBound: function(e) {
e.sender.tbody.find(".k-grid-hideRow").click(evt => {
const row = evt.target.closest("tr")
const dataItem = e.sender.dataItem(row)
dataItem.set("isActive", !dataItem.isActive)
})
},
dataSource: [{ name: "Jane Doe", isActive: false }, { name: "Jane Doe", isActive: true }]
});

JSON post request to slack returns invalid_auth

I'm trying to open a dialog in slack through a google app script after the user presses a button but i'm getting the following error message:
{"ok":false,"error":"invalid_auth","warning":"missing_charset","response_metadata":{"warnings":["missing_charset"]}}
This is my code:
function openDialog (range, triggerId, token) {
var url = 'https://slack.com/api/dialog.open';
var dialog = {
trigger_id: triggerId,
title: 'Submit a helpdesk ticket',
callback_id: 'submit-ticket',
submit_label: 'Submit',
elements: [
{
label: 'Title',
type: 'text',
name: 'title',
value: 'teste',
hint: '30 second summary of the problem',
},
{
label: 'Description',
type: 'textarea',
name: 'description',
optional: true,
},
{
label: 'Urgency',
type: 'select',
name: 'urgency',
options: [
{ label: 'Low', value: 'Low' },
{ label: 'Medium', value: 'Medium' },
{ label: 'High', value: 'High' },
],
},
],
};
var options = {
'method' : 'post',
'contentType': 'application/json',
'headers': {
'Authorization': 'Bearer ' + token,
},
'payload' : JSON.stringify(dialog),
};
var urlFetch = UrlFetchApp.fetch(url, options);
var message = ContentService.createTextOutput(urlFetch).setMimeType(ContentService.MimeType.JSON);
return message;
}
Can anyone spot what I'm missing?
Thanks
Here's the doPost() function triggering the openDialog() function it reads a payload from a button in slack with callback_id = "gasolina" and value = "update" :
if (payload.callback_id == "gasolina") {
var selectedOption = actions.value;
var operation = payload.callback_id;
var triggerId = payload.trigger_id;
var token = payload.token;
var inputRow = actions.name;
if (selectedOption == 'update') {
var keyword = 'no+money';
var gastoExtra = '';
var operation = payload.callback_id;
var gastoExtraRange = actions.name;
return openDialog (gasRange, triggerId, token);

I think that although your script is almost correct, a little modification is required. How about this modification for your script? From your question, I'm not sure about your current settings for using dialog.open of Slack. So this modified script supposes that the settings is correct.
Modification points :
Reason of missing_charset is due to using JSON.stringify() to the payload.
From the document of dialog.open, the payload is token, dialog and trigger_id.
token doesn't use for the header.
application/json doesn't use for contentType.
When these points are reflected to your script, the modified script is as follows.
Modified script :
function openDialog (range, triggerId, token) {
var url = 'https://slack.com/api/dialog.open';
var dialog = {
title: 'Submit a helpdesk ticket',
callback_id: 'submit-ticket',
submit_label: 'Submit',
elements: [
{
label: 'Title',
type: 'text',
name: 'title',
value: 'teste',
hint: '30 second summary of the problem',
},
{
label: 'Description',
type: 'textarea',
name: 'description',
optional: true,
},
{
label: 'Urgency',
type: 'select',
name: 'urgency',
options: [
{ label: 'Low', value: 'Low' },
{ label: 'Medium', value: 'Medium' },
{ label: 'High', value: 'High' },
],
},
],
};
var options = {
method: 'post',
payload: {
token: token,
dialog: JSON.stringify(dialog),
"trigger_id": triggerId,
},
};
var urlFetch = UrlFetchApp.fetch(url, options);
var message = ContentService.createTextOutput(urlFetch).setMimeType(ContentService.MimeType.JSON);
return message;
}
Note :
In my environment, I'm using dialog.open with the request like above script. But if this didn't work, please check the error messages and modify your settings.

if you request by application/json.
You use to header.authorization.

Kendo Grid multiselect checkboxes

I have a Treeview. On selecting the edit of the treenode a kendo grid for Roles will be displayed and few textboxes (where is edit other properties for roles). The kendo grid for roles have checkboxes and Rolenames. My current code is working if I select one checkbox.
What I need is how I get the array of the ids of the roles if I check multiple checkboxes. Tried multiple ways but I am not getting the list of ids when multiple checkboxes are selected. On click edit of the node EditNode is triggered and on click of save the 'click' is trigerred.
Below is my code:
function editNode(itemid) {
var editTemplate = kendo.template($("#editTemplate").html());
var treeview = $("#treeview").data("kendoTreeView");
var selectedNode = treeview.select();
var node = treeview.dataItem(selectedNode);
$("<div/>")
.html(editTemplate({ node: node }))
.appendTo("body")
.kendoWindow({
title: "Node Details",
modal: true,
open: function () {
console.log('window opened..');
editDS = new kendo.data.DataSource({
schema: {
data: function (response) {
return JSON.parse(response.d); // ASMX services return JSON in the following format { "d": <result> }.
},
model: {// define the model of the data source. Required for validation and property types.
id: "Id",
fields: {
Id: { editable: false, nullable: false, type: "string" },
name: { editable: true, nullable: true, type: "string" },
NodeId: { editable: false, nullable: false, type: "string" },
}
},
},
transport: {
read: {
url: "/Services/MenuServices.asmx/getroles",
contentType: "application/json; charset=utf-8", // tells the web service to serialize JSON
type: "POST", //use HTTP POST request as the default GET is not allowed for ASMX
datatype: "json",
},
}
});
rolesGrid = $("#kgrid").kendoGrid({
dataSource: editDS,
height: 150,
pageable: false,
sortable: true,
binding: true,
columns: [
{
field: "name",
title: "Rolename",
headerTemplate: '<span class="tbl-hdr">Rolename</span>',
attributes: {
style: "vertical-align: top; text-align: left; font-weight:bold; font-size: 12px"
}
},
{
template: kendo.template("<input type='checkbox' class = 'checkbox' id='chkbx' data-id='#:Id #' />"),
attributes: {
style: "vertical-align: top; text-align: center;"
}
},
],
}).data('KendoGrid');
},
})
.on("click", ".k-primary", function (e) {
var dialog = $(e.currentTarget).closest("[data-role=window]").getKendoWindow();
var textbox = dialog.element.find(".k-textbox");
var LinKLabel = $('#LL').val();
var roles = $(chkbx).data('roleid');
console.log(PageLocation);
node.text = undefined;
node.set("LINK_LABEL", LinKLabel);
node.set("Roles", roles);
dialog.close();
var treenode = treeview.dataSource.get(itemid);
treenode.set("LINK_LABEL", LinKLabel);
treenode.set("id", Id);
treenode.set("roles", roles);
treenode.LINK_LABEL = LinKLabel;
treenode.ID = Id;
treenode.roles = roles;
var rid = $(chkbx).data('roleid');
$.ajax({
url: "/Services/MenuServices.asmx/UpdateTreeDetails",
contentType: "application/json; charset=utf-8",
type: "POST",
datatype: "json",
data: JSON.stringify({ "Json": treenode })
});
console.log(JSON.stringify(treenode));
})
}

I'm assuming you want to get those ids in this line:
var roles = $(chkbx).data('roleid');
Right? What I don't know is the format you want to get that data. With the following code you can get the roles data in an array objects like this { id: 1, value: true }, check it out:
var grid = $("#grid").data("kendoGrid"),
ids = [];
$(grid.tbody).find('input.checkbox').each(function() {
ids.push({
id: $(this).data("id"),
value: $(this).is(":checked")
});
});
Demo. Anyway you want it, you can change it inside the each loop.
Update:
To get only the checked checkboxes, change the selector to this:
$(grid.tbody).find('input.checkbox:checked')

Send array of Objects to MVC Controller

I try to send an array of json objects to server:
var objectData = [
{ Description: "Bezeichnung", Value: "1", Name: "Betrag (Brutto)" },
{ Description: "Dies ist die erste Bezeicnung", Value: "101", Name: "11,90" },
{ Description: "Dies ist die zweite Bezeicnung", Value: "12", Name: "11,90" }
];
$.ajax({
url: "/system/createinvoice",
data: JSON.stringify({ pos: objectData }) ,
dataType: 'json',
type: 'POST',
});
C#
public class InvoicePos
{
public string Description { get; set; }
public Nullable<double> Value { get; set; }
public string Name { get; set; }
}
[POST("/system/createinvoice")]
public void newquestion2(InvoicePos[] pos)
{
// pos is always null
}

The dataType property is saying what you expect back from the server. Try setting the contentType:
contentType: 'application/json'

Try
data: JSON.stringify({ pos: #objectData })
Also, check what is being rendered in the View through the browser. The reason you are getting null is likely because JavaScript is not getting a proper value.

function SendArrayOfObjects()
{
var things = [{ id: 1, color: 'red' }, { id: 2, color: 'blue' }, { id: 3, color: 'yellow' }];
$.ajax({
type: "POST",
url: "<%= ResolveUrl("~/MyServices.aspx/GetData")%>",
data: JSON.stringify({ objdata: things }),
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function()
{
$("#msg").html("data sent successfully!");
},
error: function()
{
$("#msg").html(" Can not send data!");
}
});
}

ckeditor plugin dialog select get the description from the selected one

Im am developing a placeholder plugin to CKEDITOR and it´s basically complete. The problem I have is that I am trying to get the value and description from the select within the dialog and I am only getting the value.
The array that contains the description and value looks like this
-->
items: [['description1', 'value1'], ['description2', 'value2']] <--
In the return -> contents -> elements with ID dropdown I have setup and commit function. In these functions I need to get the description just like getting the name from select option.
Really need help with this one, thanks in advance
example -->
<select>
<option value="value1">description1</option>
<option value="value2">description2</option>
</select>
example <--
(function () {
function placeholderDialog(editor, isEdit) {
var lang = editor.lang.phlink,
generalLabel = editor.lang.common.generalTab;
return {
title: lang.title,
minWidth: 300,
minHeight: 80,
contents: [
{
id: 'info',
label: generalLabel,
title: generalLabel,
elements: [
{
id: 'dropdown'
, type: 'select'
, label: lang.chooseVal
, 'default': 'Detta är default'
, items: [['description1', 'value1'], ['description2', 'value2']]
, setup: function (data) {
// need the description
this.setValue(data.title);
}
, commit: function (data) {
// need the description
data.title = this.getValue();
}
},
{
id: 'text',
type: 'text',
style: 'width: 100%;',
label: lang.text,
'default': '',
required: true,
validate: CKEDITOR.dialog.validate.notEmpty(lang.textMissing),
setup: function (data) {
this.setValue(data.text);
},
commit: function (data) {
data.text = this.getValue();
}
}
]
}
],
onShow: function () {
var data = { tag: 'link', content: "detta är innehåll", title: "Länk till svar", text: "detta är text" };
if (isEdit) {
this._element = CKEDITOR.plugins.phlink.getSelectedPlaceHolder(editor);
data.title = this._element.getAttribute('title');
data.text = this._element.getText();
data.tag = this._element.getAttribute('data-jztag');
}
this.setupContent(data);
},
onOk: function () {
var data = { tag: 'link', content: null, title: null, text: null };
this.commitContent(data);
CKEDITOR.plugins.phlink.createPlaceholder(editor, this._element, data);
delete this._element;
}
};
}
CKEDITOR.dialog.add('createplaceholder', function (editor) {
return placeholderDialog(editor);
});
CKEDITOR.dialog.add('editplaceholder', function (editor) {
return placeholderDialog(editor, 1);
});
})();

Use the following to get option's text:
var input = this.getInputElement().$;
console.log( input.options[ input.selectedIndex ].text );
>> "description1"
