Hi,

My CSP settings on the server-side:

Response.AddHeader("Content-Security-Policy", "default-src 'self'; script-src 'self' https://code.jquery.com 'nonce-kendoInlineScript' https://kendo.cdn.telerik.com; connect-src 'self'; img-src 'self' 'unsafe-inline' blob: data: gap:; style-src 'self' 'unsafe-inline' https://kendo.cdn.telerik.com; font-src 'self' data:;");

My CSP settings on the front-end:

And I get the following error:

Now of course, when I add 'unsafe-eval' in the CSP settings/config, the errors will be gone but it's not ideal since at the end of the day, it's still a security risk however low.

BTW, I'm using CDN to load the JQuery and Kendo js:

I would greatly appreciate if you can give some assistance.

Thanks,

JT

MVVM datasource jQuery input stoped working after upgrade

Hello,

we recently upgraded from Kendoui 2022 to the latest version and our MVVM forms stoped working.

So either there are changes to the datasource or MVVM or both.

Any ideas how to fix it?

The input elements look like this:

<input  data-bind="value: emailTextSource.data()[0].siteGroup" name="siteGroup" id="siteGroup" value="" class=" form-control" />

Here is the datasource and the binding:

<script>
	var crudServiceBaseUrl = 'emailTexts';
	var myData = new kendo.data.DataSource({
        transport: {
            read: {
                url: crudServiceBaseUrl + "/getdetails?id=1",
                dataType: "json"
            },
            update: {
                url: crudServiceBaseUrl + "/updatedetails",
                dataType: "json",
                type: 'get'
            },
            destroy: {
                url: crudServiceBaseUrl + "/destroydetails",
                dataType: "json"
            },
        },
        schema: {
            model: {
                id: "id",
                fields: {
                	    }
            }
        }
    });
	var viewModel = kendo.observable({
    	emailTextSource: myData,
		language: [{"language":1,"text":"Deutsch","logger":"","wirebox":"","languageId":1,"id":1,"validationResult":""},{"language":1,"text":"Englisch","logger":"","wirebox":"","languageId":2,"id":3,"validationResult":""}], delete: function(e) {
			if (confirm('Sind Sie sicher?')) {
			    this.emailTextSource.remove(this.emailTextSource.data()[0]);
				this.emailTextSource.sync();
			} else {
			    // Do nothing!
			}
		}
		, save: function(e) {
			if (confirm('Speichern?')) {
				myData.sync();
			} else {
			    // Do nothing!
			}
		}
		
	});
	kendo.bind($("#emailTextDiv"), viewModel);
	myData.read();

</script>

MVVM

The Kendo context menu does not appear in the modal popup.

Hello,

I'm using a model popup in which I bind the kendo grid and set the grid right-click to open the context menu. However, the context menu does not appear. I'm using Kendo 2023.2.606 version. Please leave your feedback.

This below same code work fine in normal page. But, it's not working in model popup.

Context menu Code is here:

<ul id="clientSearchGridContextMenu" class="hide">
<li id="clientSearchGridContextMenuAddFavourite">@Resource.lblAddFavourite</li>
<li id="clientSearchGridContextMenuRemoveFavourite" class="border-bottom-div">@Resource.lblRemoveFavourite</li>
<li id="clientSearchGridContextMenuClose">@Resource.lblClose</li>
</ul>

JavaScript code for context men:

bindClientSearchGridContextMenu: function (favourites) {
clientManagement.variable.clientSearchGridContextMenuAddFavourite.css('display', favourites ? 'none' : 'block');
clientManagement.variable.clientSearchGridContextMenuRemoveFavourite.css('display', favourites ? 'block' : 'none');

clientManagement.variable.clientSearchGridContextMenu.kendoContextMenu({
target: "#clientMatterGrid",
filter: "tbody > tr",
open: function (e) {
clientManagement.variable.clientSearchGridContextMenu.addClass("show");
let node = $(e.target);
$("#clientMatterGrid").data('kendoGrid').select(node);
},
select: function (e) {
let node = $(e.target);

$("#clientMatterGrid").data('kendoGrid').select(node);

switch ($(e.item).attr('id')) {
case "clientSearchGridContextMenuAddFavourite":
clientManagement.addRemoveFavourite(true);
break;
case "clientSearchGridContextMenuRemoveFavourite":
clientManagement.addRemoveFavourite(false);
break;
case "clientSearchGridContextMenuClose":
clientManagement.variable.clientSearchGridContextMenu.data("kendoContextMenu").close();
break;
}
}
});
}

Kendo MultiSelect with Virtualization: DataSource Data Empty for a Few Milliseconds

$("#msUsers").kendoMultiSelect({
        placeholder: "Select Users...",
        autoClose: false,
        dataTextField: "UserName",
        dataValueField: "UserId",
        virtual: {
            itemHeight: 40,
            mapValueTo: "dataItem",
            valueMapper: function (options) {
                var ids = options.value;
                if (!ids.length) {
                    options.success([]);
                    return;
                }
                $.ajax({
                    url: "/Home/GetUserByIds",
                    traditional: true,
                    data: { ids: ids },
                    success: function (response) {
                        options.success(response.length ? response : []);
                    },
                    error: function (xhr) {
                        console.log("Error:", xhr.responseText);
                    }
                });
            }
        },
        dataSource: {
            transport: {
                read: {
                    url: "/Home/BindUsers",
                    dataType: "json",
                    data: function (options) {
                        return {
                            skip: options.skip,
                            take: options.take,
                            filter: options.filter
                        };
                    }
                },
                parameterMap: function (data, action) {
                    if (action === "read") {
                        return {
                            take: data.take,
                            skip: data.skip,
                            filter: data.filter?.filters?.[0]?.value || ""
                        };
                    }
                    return data;
                }
            },
            schema: {
                data: "Data",
                total: "Total"
            },
            pageSize: 40,
            serverPaging: true,
            serverFiltering: true
        }
    });

I’m using Kendo UI MultiSelect with virtualization enabled, and I’ve noticed an issue where calling:


$("#multiSelect").data("kendoMultiSelect").value([1,2]);  //Where [1,2] already exists in the dataSource.

Immediately after setting the value, I attempt to retrieve it, but the result is an empty array [].
I tested this with setInterval(), and for a few milliseconds, the value remains empty before updating correctly.
My code logic requires retrieving the value immediately after setting it and passing it to an API call. However, as mentioned, I receive an empty array.
Is there an event I can listen for before proceeding?
I could use setTimeout(), but that feels like a hack.

How to manipulate the text of the k-group-indicator button

In my formatting of the grid I set the grid column titles. However when the user groups by the columns the k-group-indicator button uses the same "Title". Is there a way to have the k-group-indicator display a different text? My issue is that it doesn't format as HTML the same as the grid so it displays the html markup " </th>" which is not what I want.

{
field: "ClientName", title: "[[[Client Name]]]",
template: "#= data.ClientName #",
width: 100,
groupHeaderTemplate: "[[[Client Name]]] ${data.value}",
hideOnGroup: true
},
{
field: "Acct", title: "[[[Account Number]]]",
template: "#= data.Acct #",
width: 100,
groupHeaderTemplate: "[[[Account Number]]] ${data.value}",
hideOnGroup: true
},

 {
                    field: "ClientName", title: "[[[Client<br/>Name]]]",
                    template: "#= data.ClientName #",
                    width: 100,
                    groupHeaderTemplate: "[[[Client Name]]] ${data.value}",
                    hideOnGroup: true
                },
                {
                    field: "Acct", title: "[[[Account<br/>Number]]]",
                    template: "#= data.Acct #",
                    width: 100,
                    groupHeaderTemplate: "[[[Account Number]]]  ${data.value}",
                    hideOnGroup: true
                },
