Dear Kendo-Team,

 

When using the less-based Bootstrap theme, the PDF export of a grid shows strange borders underneath header's column menus. Refer to the following DOJO for replication:

 

https://dojo.telerik.com/ePOSiluT

 

Enclosed you will find a screenshot of the PDF export, showing the strange borders.

 

Is this something we can easily (temporarily) fix on our own by adjusting some CSS styles?

 

Bye

Ralf

The details for this can be found in ticket #1519224

Given some XML that has child nodes and attributes, I'm binding to a grid with no problem. The child grid for each row (built using detailInit) get's the data from the parent row e.data.get("BillRows")

If those rows have attributes, the '@' signs breaks the javascript for the grid. As you can see in the ticket, every attribute needs to be renamed before I can build the child grid.

Should be a way to use attributes in XML bound to a datasource/grid for all levels of grids.

The Kendo-UI Grid supports the concept of locked columns that are always on the left side of the screen (in a non-RTL-world) and do not scroll. This makes it necessary to split the underlying HTML-table into two parts (one is locked and one is not). Kendo-UI takes care of syncing the height of the rows between those two tables.

However, if there are empty cells in the locked part, this logic produces results that make the row grow larger (higher) than if there was content. This DOJO demonstrates the behaviour. Using the Browser's DEV-Tools, you can see that rows without content in column A are 37px high, while those with content are only 36px high.

Hi,

In my kendo grid , when i apply a filter to 2 columns, first i apply filter to numeric column which results in no value and then after that i applies the filter to a string column combined with numeric column which also results to no value, Nothing is displayed. But when i remove the value from textbox of numeric column and enter filter, no data being displayed as string column filter is there but in case i remove the value from textbox of string column and enter filter , numeric column filter also got removed.

I also checked the kendo functionality , but not getting any solution for this problem.

Bug report
Download Builder Tool does not add all dependencies for Grid

Reproduction of the problem

Download Builder Tool does not add Chip and ChipList as dependencies that are needed when grouping is enabled.

Expected/desired behavior
Al dependencies shall be added to the Grid

Environment
Kendo UI version: [all]
Browser: [all]

We would like to add a new column(s) dynamically to a grid, This feature is very important when grid containts lots of fields. In order to resolve slow grid rendering, we are allowing user to choose columns to show/hide and render grid accordingly. Kendo generates html code for hidden columns which causes slow rendering for large data. We are already using performance improvement suggestions from kendo like virtual scrolling, paging etc.

Bug report

Bug report

When setting column attribute that contains "_" in the Grid, an error is thrown.

Reproduction of the problem

1. Open this Dojo example - https://dojo.telerik.com/uPuDeTUk/4
2. Open the browser console

Current behavior

An error is thrown due to the 'cause_error' attribute for the classification column

Expected/desired behavior

No errors should be thrown

Hi Guys,

Have just tripped over another regression in the 2023.1.314 release whereby resizing of a locked column also effects the sizing of any prior columns.

Reproduction of the problem

    Open the Grid Frozen Column Demo
    Decrease the size of the 'Ship Name' column

Current behaviour

As the width of column header decreases you hit a point where the width of the related data cells stop decreasing but the width of the data cells in previous columns start to decrease causing column misalignment. See attached screenshot.

Expected behaviour

Only the selected column should resize and previous columns should remain fixed.

Alan

Hi Guys,

Have just tripped over an issue with grid checkboxes whereby they cannot be accessed via the keyboard.

To illustrate

    - Run the following dojo
           https://dojo.telerik.com/ojODosUL

    - Select any checkbox then try tabbing to the next ... It doesn't happen.

If you look at the checkboxes using the browser's dev tools you will see the header and cell checkbox inputs have been assigned the attribute tabindex="-1" so it's no wonder they cannot by accessed.

This regression seems to have been introduced with version 2022.2.802

Looking at the release notes for this version I don't see any mention of this breaking change so it looks like its another bug which has been kicking around for a while which your QA accessibility testing hasn't picked up on.

Regards
Alan

Bug report

When the filterable mode is enabled in the Grid and the user has to scroll to the needed column, then the Column Menu autocloses right after a column is selected or deselected in the column list in the ColumnMenu. The issue appears only with 'classic' mode.

Reproduction of the problem

1. Open the Dojo or the Demo.
2. Scroll to the last column and uncheck/check one of the columns.

Current behavior

The ColumnMenu immediately closes. The ColumnMenu does not close when it is used for the initially visible columns.

Expected/desired behavior

The ColumnMenu should not close. The behavior should be consistent for all the columns.

The issue is a regression starting with 2022 R1 (2022.1.119) release

Environment

• Kendo UI version: 2024.3.806

Bug report

The popup of the filter does not contains all items after selecting the timepicker.

Reproduction of the problem

1. Open the Filter Demo
2. Open the filter popup for the Birth Date.
3. Click on the 'clock' icon to display time.

Current behavior

The filter popup is closed. After the filter is opened again it displays only times. The filter popup should be closed and opened again to be rendered as expected.

Expected/desired behavior

After selecting the TimePicker the filter popup should not close, should display times.

The issue is a regression starting with 2023 R1 SP1 (2023.1.314)

I'm trying to test the accessibility of the grid detailTemplate on https://demos.telerik.com/kendo-ui/grid/detailtemplate , namely keyboard navigation.

Honestly, I don't even know where I am. I know when I'm focused on the button "Edit in theme builder" (it's barely visible, but visible), and when I press tab, document.activeElement points to the first table header ("Last Name"), but it's not visible at all. Then I keep getting lost.

I have tested it with all sass-based themes and the less-based Material theme.

Bug report

Navigatable Grid with hierarchy moves focus to the top parent row On click of horizontal scroll bar in child grid

Reproduction of the problem
Open the Dojo: https://dojo.telerik.com/OJAYoCak

 - Expand the first parent row or second parent row to render the child records.

 - Navigate the child rows downwards using vertical scroll and click the Horizontal scroll area of the inner grid (Red Rounded area).

 - Control Focus immediately shifts to the top row and the user can’t use horizontal scroll to view the columns in the child grid.

Also, if the user initially clicks on any cell in the School Name column focus is moved.

Environment
Kendo UI version: [all]
Browser: [all]

Add support for flexible width to columns on a "weight" basis (like XAML grid).

Ps. I'm writting the example in MVC wrappers because I'm not familiar with the javascript initialization but I am posting this in Kendo UI Web category because it's a core feature and assume it would be implemented accordingly in every wrappers without having to specify them.

@(Html.Kendo()
  .Grid<Employee>()
  .Name("EmployeesGrid")
  .Columns(cols =>
  {
    cols.Bound(o => o.FirstName).Width("*");
    cols.Bound(o => o.LastName).Width("2*");
    cols.Bound(o => o.Initials).Width("Auto");
    cols.Bound(o => o.JobTitle).Width("200"); // Or 200px
  }))

-Assuming the grid is 900 pixel wide and the longest Initials (including header?) is 100 pixel
-Ignoring the lost horizontal space in padding, margin, borders, scrollbars and anything else

This example would give the following result:
FirstName column: 200px
LastName column: 400px
Initials column: 100px
JobTitle column: 200px

Environment (OS, Application, Versions): Chromium Edge Version 119.0.2151.72 (Official build) (64-bit)

Repro Steps : 

1. Lauch the application using URL: https://dojo.telerik.com/UZIkuGoD
2. “Kendo UI ® Dojo by Progress” screen should open.
3. TAB to “Run” button and hit ENTER key.
4. TAB to "First Name" column in the table and press CTRL + SPACE key.
5. Observe that by pressing CTRL + SPACE key whether the table columns are getting grouped or not.

 

Actual Results: User is not able to group/ungroup the table column header using keyboard with CTRL + SPACE key.

Expected Results: User should be able to group/ungroup the table column header using keyboard with CTRL + SPACE key.
