We are using the latest version (5.4.0) of the "Classic" SASS theme for Kendo UI and override several scss variables to adapt the grid's look&feel to our requirements. One thing we did was setting $grid-header-padding-x and $grid-header-padding-y to 2px each.

If the content of the grid header is long enough to be truncated, sorting indicators etc. are partially moved out of the cell.

Since I cannot modify scss variables in DOJOs, I have tried to apply CSS styles to simulate the behavior: https://dojo.telerik.com/EMOYUREh.

As you can see, the th element applies some padding that .k-cell-inner removes again. On the right side, however, the negative margin is bigger than the padding added by the th element which causes the content to move out of the cell.

Hi team,

Found an issue with column filterable property on IE 11 and last kendo UI for jQuery release.

Please have a look at this dojo with IE11: https://dojo.telerik.com/UfIZePaZ

Using property "filterable: { multi: true}" on first column leads to the grid not being built with console error.

Regression bug as it works with previous kendo release.

Regards,

Laurent.

Bug report

When the Kendo UI Grid is initialized with the bind method utilizing MVVM, the columns.template is correctly bound based on the data-role, but the columns.headerTemplate does not render like the template.

Reproduction of the problem

Please take a look at the following Progress Kendo UI Dojo.

Current behavior

The column.headerTemplate does not render the elements containing a data-role.

Expected/desired behavior

The elements which contain a data-role should become widgets upon binding.

Environment

• Kendo UI version: 2022.2.510
• jQuery version: All supported versions
• Browser: All

Hi Team,

I'd like to request when the Kendo UI Grid contains a checkbox within the HeaderTemplate to allow it to render with the k-checkbox class like within a column.template.  Please take a look at this example which shows the current behavior.

Thank you!

Bug report

Shift selection is not working correctly when multi-column headers are configured in a grid and selectable: "multiple cell" is configured


Reproduction of the problem

Current behavior
Shif selection not working correctly


Environment
Kendo UI version: 2022.2.510
jQuery version: any. Demo 1.12.4 and our code is 3.6.0
Browser: [all]

Hi Team,

I have some feedback regarding the Kendo UI Grid live demo pertaining to localStorage and the columns.  I would like to request some built-in defensive approaches to help if columns are removed or added.  For example, a way to detect if a column is missing from a previously saved state.  

Thank you!

Hello again Kendo Support,

I believe I have found a bug with the kendo grid when using column virtualization. When turning on selectable rows, row selection is lost upon horizontal scroll. The bug can be easily reproduced using the following sample: https://dojo.telerik.com/osUKOZol

Is there any work around or plans to fix this bug in the future? Turning on virtual columns was a performance boost for our application and we'd hate to have to turn it off. 

Hi,

I've found a bug in the jQuery template code for Kendo Grids. Seems that it directly injects the name of a field from the data source results under the assumption that the field name is a valid JavaScript identifier (i.e. data.someIdenifier). But when the data source results contain a field name that is a number (as in my case), this results in invalid JavaScript (i.e. data.1234) and causes the Kendo Grid code to error. I notice that in some places in the template code, indexing is used instead of member access (data['someIdentifier'] instead of data.someIdentifier), but not everywhere. I'd recommend using indexing every where to fix this (i.e. data[1234]).

I am trying to change the menu option for a column from false to true and others from true to false when a user selects an item from a dropdown. This isn't working. I'm using getOptions(), changing the menu setting in each column, and then setOptions(options) to set it.

Here is a dojo showing an example. In the example, firstName and lastName are initially hidden. I simulate a user choosing last name from some sort of selector (like a dropdown box). The code should then hide both name columns and unhide the lastName column. Instead it hides both name columns.

It seems to have something to do with setting any of the name columns to hidden on initialization. If I remove this from the column settings on initialization though it only works once and when I choose a different option from the dropdown (dropdown is simulated in the dojo so you can't try this but trust me) it breaks.

I've noticed the .k-command-cell class is being added multiple times to the Grid's command cell.

This can be seen on the Grid's Custom Command demo page, where the class is added twice.  On some of my Grid implementations, the class is added 100 times or more.

Dojo:

https://dojo.telerik.com/EweloVOD 

Inspect one of the command cells and observe the "class" attribute.

It is possible to add new inline rows to grid even though they are not valid. 

Steps to replicate in attached dojo:

https://dojo.telerik.com/oJEMAPoJ

1. Apply any search in search panel

2. Click Add New Record (one or mutiple times)

3. Click SaveChanges

4. Delete search phrase

The result is that new rows have been added with empy ProductName column, which supposed to be required.

Bug report

Grid with group paging and server operations enabled throws a JavaScript error when expanding groups. Reported in ticket 1560566.

Reproduction of the problem

1. Run this dojo
2. Follow the steps in this screencast to reproduce the error

Current behavior

A JavaScript error is thrown:

Expected/desired behavior

No error should be thrown group paging should work as expected

Environment

• Kendo UI version: 2022.1.301
• Browser: [all]

This started happens on 2022.1.119 and 2022.1.301, Works well on 2021.3.914

Some of ours grids stopped showing the filter icon in the columns.

After digging a bit found that the issue happens when I have a grid initialized with sortable = true and then initialize a new one with sortable = false

You can see this happening in this example:

https://dojo.telerik.com/ogUZEbUP

the issue seems to be caused by this:

this selector is catching all the k-cell-inner from the first grid

Bug report

When custom Virtual DropDownList filter is set the value is not cleared from the DropDownList on Clear button click

Reproduction

1. Filter Ship Name column

2. Open the filter menu and hit Clear

3 Open Filter menu again

### Bug report

When reordering expanded rows, the "rowReorder" event does not return a correct "oldIndex".

### Reproduction of the problem

1. Create a hierarchical grid and enable the reorderable.rows property;

2. Expand all rows;

3. Handle the "rowReorder" event and log the event data in the browser console;

4. Move the second row above the first row. The property "oldIndex" returns a wrong value. It should be "1".

A Dojo sample for reproduction: https://dojo.telerik.com/AJIGuBEh

### Expected/desired behavior

The "rowReorder" event of the grid should return the correct indexes of the moved row.

### Environment

* **Kendo UI version: 2022.1.301
* **jQuery version: 1.12.4
* **Browser: [all]

Hi Team,

I would like to request adding RowVersion support to the Kendo UI Grid.  Currently, I am using a workaround of setting it during the save event, but you guys really need to fix that. 

Thanks!
