Hi

I've been playing around with the barcodes widget and I've noticed some confusing behaviour on the examples available.

I initially used the cheese example with some valid barcodes and noticed that entering an EAN13 in its full 13 digits causes an error and fails to show any barcodes. Using https://demos.telerik.com/kendo-ui/barcode/index if you change the code for the first item (Manchego) and change it to EAN13 and then enter a valid EAN13 (eg 9300657234720) it not only shows no barcode but also obliterates all of the following barcodes. If you remove the check digit (the last digit) then everything works.

I then found the API example https://demos.telerik.com/kendo-ui/barcode/api where I worked out what is happening. The Kendo widget is accepting ONLY the first 12 digits and then calculating the check digit for itself. So entering 

930065723472

will generate a valid barcode and will correctly calculate the check sum as 0.

However this means that the security of the checksum is stripped out meaning that if an end user manually types the example 

9300657234720

without the checksum  so

930065723472

but makes a transposition error with the last 7 with the last 4 to 

930065723742

then it will still generate a valid barcode 

930065723742 4

However the original barcode is for baked beans and the erroneously created barcode does not exist as a product.

Further if the original barcode is checked in its entirety but has the transposition error with the 4 and the 7 with the checksum 0 then this error would be caught https://barcode.tec-it.com/en/EAN13?data=9300657237420

So, my question is how do I use the Barcode widget and a full EAN13 with check digit to ensure that data entered is correct and that the barcode being generated is for baked beans not non existent products?

Hi, 

Would love to know how to hide cells based on the value OR order of rows.

Here is what I have coming in:

It is a merged cell by Staff Name.

Here is what I want initially when the grid is populated:

Then… If I click on the toggle button, or the row… this would work too it would  expand like this:

Trying to figure out how to filter off of the value TOTAL in the 5th column… then click a button on the 5th column (Pay Code) …and have it fully populated. The merge cell stuff I think I have got. Any idea how I could accomplish this?

Regards,

I'm trying to paint the spreadsheet with data of 3500 rows * 250 columns and I'm having few loops to prepare the data before the below code and trying to set it all at once. The below code took ~ 2 min

Is there any way improve this ?

Hello community, how are you?

I need to replicate a filter like the one in this image. This is inside a kendoGrid filter, but I can't replicate something similar with MultiSelect and CheckboxGroup. 

Supposedly this function is what makes this filter look like that:

function categoryDropdownEditor(container, options) {
        $('<input required data-bind="value:' + options.field + '"/>')
            .appendTo(container)
            .kendoDropDownList({
                dataSource: fk_categoriesDatasource,
                dataTextField: "category",
                dataValueField: "id",
                filter: "contains",
                minLength: 1
            });
    }

My kendoGrid is configured like this:

$("#grid").kendoGrid({
        dataSource: dataSourceGrid,
       
        autoBind: true,
        scrollable: true,
        sortable: true,
        filterable: true,
        groupable: true,
        resizable: false,
        loaderType: "skeleton",
        pageable: {
            refresh: true,
            numeric: false,
            input: true,
            previousNext: true,
            alwaysVisible: true
        },
        noRecords: {
            template: function (e) {
                return "No hay datos disponibles.";
            }
        },
        columns: [
            {
                title: "Categoría",
                field: "category_id",
                dataTextField: "category",
                dataValueField: "id",
                editor: categoryDropdownEditor,
                filterable: {multi: true},
                dataSource: {
                    transport: {
                        read: {
                            url: apibaseurl + endpoint + "/categories",
                            type: "GET",
                            dataType: "json",
                            beforeSend: addToken,
                        },
                    },
                    schema: {
                        data: "data",
                        total: "total",
                        model: {
                            id: "id",
                            fields: {
                                category: {type: 'string'},
                            }
                        }
                    },
                },
            },
            
            {
                command: [
                    "edit",
                    {
                        name: " ",
                        iconClass: "k-icon k-i-more-vertical",
                    }
                ],
                title: " ",
                width: 210
            }],
        editable: "popup",
    });

I apologize if it is not understood or if I forgot to put something, it is my first post here.

Thank you very much for your attention.

Hello Kendo practitioners!
I'm currently working on creating a complex input field.
As shown below, I want to input 3 fields in 4 columns, and I want to make the 2nd field use 2 columns.

So I tried writing code like this, but it didn't work.

            $("#baseForm").kendoForm({
                orientation: "horizontal",
                layout: "grid",
                grid: {
                    cols: 4,
                    gutter: 0
                },
                items: [
                            {
                                field: "field1",
                                label: "field1",
                            },
                            {
                                field: "field2",
                                label: "field2",
                                attributes : {colspan: 2}
                            },
                            {
                                field: "field3",
                                label: "field3",
                            },
                        ],
                buttonsTemplate:'',
                submit: function(e) {
                    e.preventDefault();
                }
            });

Hi

Our development team is installing all the library files in the project in order to work with it, is that right?

We're in the middle of a migration to GitLab SaaS, and the project using Kendo has a very large repository (too much for migration), so I'm thinking -  Is there a better and easier way to work with the Kendo code?

Did anyone try to use it as a Git sub-module?

any other way that won't enlarge our code?

Thanks!

Hi Team,

I've added everything to make sure charts are accessible but the issue is our data points are clickable and when we click on our data points the pivot/grid below the charts updates just like power bi charts.

I saw one document shared by kendo UI on charts accessibility:

The fundamental requirement that refers to and is fulfilled by the Kendo UI data visualization components is:

• Section 508—"(a) A text equivalent for every non-text element shall be provided (e.g., via alt, longdesc, or in-element content)."
• WCAG 2.1—"Guideline 1.1 Text Alternatives: Provide text alternatives for any non-text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language."

but this holds true when charts are not clickable.

Like this we're expecting to have focus on each data points:

Power bi is also using svg image and all data points and the x and y axis are operable through the keyboard. Please have a look.

1. Either any shortcut key so that it can navigate all the data points.

2. or Simple Navigation : Enter => and then arrow keys to navigate inside options.

Step 1: container is clickable

Step 2: 

Tab to navigate in between

Enter to go inside

esc: to exit

Step 3: After pressing enter, it goes inside.

Is it possible to create something like this.. This will make charts more accessible.

For more inspiration: Miro currently make it canvas objects accessible in June release with the help of help keys + hidden messages for screen readers.

-----------

Is it possible to add custom patterns like pattern fill instead of solid fill inside the charts so that we create differentiation apart from the colors also?

my code is here why charts not displayed

Hello,

I have a huge volume of data loading in Kendo UI tree by ondemand set to true. With this feature I couldn't do a search since not all the child nodes are loaded. The current search feature only searches the loaded nodes in the tree.

I need to achieve the search feature with the ondemand set to true to satisfy the business need. Can you please help me here?

Thanks
