Bug report

Starting from version 2022.1.119 when the type of the button is set to 'submit' it still remains to 'button' which prevents submission of forms on click.

Reproduction of the problem

  1. Run this REPL
  2. Click the buttons

Expected/desired behavior

Type property should correctly set the button's type to 'submit'

Environment

  • Kendo UI version: 2022.1.119
  • Browser: [all]
Declined
Last Updated: 22 Jan 2022 21:17 by Cypher

Steps to reproduce

  1. Execute the code below
  2. Enter some values in the Html and Kendo inputs
  3. Hit the browser's back button
  4. Hit the browser's forward button to redisplay the page

Current Behavior

The value in the Html Input is restored but not the value of the Kendo Input. The same behavior applies for Kendo NumericTextBox, etc.

Bug report

A DataSource defined using TagHelpers with disabled serverPaging sets default pageSize:

    <datasource type="DataSourceTagHelperType.Ajax" server-filtering="true" server-paging="false">
            <transport>
                <read url="@Url.Page("Index", "Read")" data="forgeryToken" />
            </transport>
            <schema data="Data">
                <model id="OrderID">
                    <fields>
                        <field name="ShipName" type="string"></field>
                    </fields>
                </model>              
            </schema>
     </datasource>

generates the following initialization script:

{"dataSource":{"page":1,"pageSize":20,"schema":{"model":{"id":"OrderID","fields":{"ShipName":{"type":"string"}}},"data":"Data","errors":"Errors","total":"Total"},"serverAggregates":true,"serverFiltering":true,"serverGrouping":true,"serverPaging":true,"serverSorting":true,"transport":{"read":{"url":"/?handler=Read","data":forgeryToken}},"type":(function(){if(kendo.data.transports['aspnetmvc-ajax']){return 'aspnetmvc-ajax';} else{throw new Error('The kendo.aspnetmvc.min.js script is not included.');}})()}

with default pageSIze set.
Initializing using jQuery works as expected:

       dataSource: {
            type: "aspnetmvc-ajax",
            serverPaging: false,
            serverFiltering:true,
            transport: {
                read: {
                    url: "@Url.Page("Index", "Read")",
                    data: forgeryToken
                }
            },
            schema: {
                model: {
                    id:"OrderID"
                },
                data: "Data",
                total:"Total"
            }
        }

Current behavior

The "page" and "pageSize" values are set, which results in only 20 items being displayed, even though more are returned by the "read" action.

Expected/desired behavior

The "page" and "pageSize" should not be set.

If you use "Edit in REPL" button in any demo that uses `kendoConsole.log()`, it will throw an error that the kendoConsole doesn't exist (you can use the Upload > Events demo as a quick example).

This is happening because the kendoConsole is only a part of demos.telerik.com pages that does not get copied over to the REPL or Dojo because it is irrelevant to the demo itself. The fix is to change all kendoConsole.log() instances to console.log()

That said, I am opening this bug report so that the dev team can consider ways to handle the "edit in" scenarios.

Thank you,

Arthur

Release 2022.R1

In ASP.NET Core, when using a TreeList with a data source that gets referenced by its id (instead of defining the data source directly on the TreeList), the built-in search functionality of the toolbar does not apply the filter to the data source. On each change of the search text the data source will send a new request, but the filter parameter is always null. When using the same approach for the Grid widget, the filter gets applied as planned. The attached project shows the behavior for both the TreeList and the Grid in detail.

Is this a bug? Is there another workaround than applying the data source directly to the TreeList (e.g. using JavaScript)?

Bug report

Setting the HeaderHtmlAttributes of the TreeList throws a Null reference exception.

Reproduction of the problem

  1. In the Multi-column headers Demo of the Treelist try adding HeaderHtmlAttributes to a Group:
@(Html.Kendo().TreeList<Kendo.Mvc.Examples.Models.TreeList.EmployeeDirectoryModel>()
        .Name("treelist")
        .Columns(columns =>
        {
            columns.Group(group => group
                .Title("Personal Info")
                .HeaderHtmlAttributes(new {@class="myClass"})

                  //...

### Bug report

When the filter is applied through the search panel, the query (more specifically, the filter expressions) is not built correctly. This results in displayed rows that have values that do not match the value from the search panel.

### Reproduction of the problem

1. Enable Search panel and group paging of the grid.

2. Set a value in the search panel and group by a column.

3. Expand the group and verify that there are items with values that do not match the filter expression from the search panel.

Short video demonstration:

https://screencast-o-matic.com/watch/crXFlXVI3i0

### Expected/desired behavior

The returned results should comply with the filter expression built from the Search panel.

### TicketID:
_1543306

### Additional notes and explanation

The Search panel builds the filter expression with the logic operator "or". While this is correct when the actual query is further built from the data source's internals (group function of the kendo.data.js file), the filter will be built with the "or" logic instead of "and". This query has to be restructured in order to send two filter objects with the "and" logic. The first filter object should contain all filter expressions built from the search panel with the "or" logic operator and the second filter object should contain an expression with the operator "eq", the field by which the group is built, and the value. The two filter objects should be combined with the "and" logic.

I have an editable kendo grid in which I have a date field. When I choose a date through the calendar for example: 26.12.2021 on post the model binder parses the date correctly.

If I manually enter the date in the cell the model binder parses the date as it was not an UTC and since my time zone is +2h it comes in the controller as 25.12.2021 22:00

(see the attached files)

 

Inside my startup.cs I have defined JsonOptions like this:

.AddNewtonsoftJson(options =>
                {
                    options.SerializerSettings.ContractResolver = new DefaultContractResolver();
                    options.SerializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Utc;
                });

 

In the Configure method:

var supportedCultures = new[] { new CultureInfo("bg-BG") };

app.UseRequestLocalization(new RequestLocalizationOptions
{
         DefaultRequestCulture = new RequestCulture("bg-BG"),
         SupportedCultures = supportedCultures,
         SupportedUICultures = supportedCultures
});

Layout.cshtml

<script src="~/lib/kendo/js/cultures/kendo.culture.bg-BG.min.js"></script>

<script>
        kendo.culture("bg-BG");
</script>
