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]

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.

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]).

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. 

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]

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,

I'd like to request a built-in event before the Grid starts a Read action.  

Thank you!

Bug report

columns.field.filterable.cell.inputWidth does not apply since R1 2022

Reproduction of the problem

Dojo: https://dojo.telerik.com/oVILIzaW

Current behavior
Width of autocomplete input is not affected

Expected/desired behavior
Width shall be reflected

Workaround

Environment
Kendo UI version: 2022.2.621
Browser: [all]

we discovered that if you have navagatable set to true and you perform a deletion using the inline delete button, the grid scrolls back to the top. setting navagatable to false prevents the scrolling from occuring.

this was using KendoGrid with JQuery.

I realize this has been covered by this workaround in the past, but the need to write extra code for moving the column back to the original position makes this seem a bit "hacky" and most importantly, the user experience of being allowed to drag the column in the first place just to see it jump back seems wrong.

The good news is that the kendoGrid already has a mechanism for preventing the columnReorder event from getting fired in the first place! The bad news is that it only happens for columns that have either of these 2 classes ["k-group-cell, "k-hierarchy-cell"]

My request is to have a configuration option that enforces that same behavior for specific columns as:

1. Add a "reorderable" flag to be set as part of the column configuration (set it to false for those we want to keep in place)

2. This flag will set a class on those columns the same way it works for columns with "k-group-cell" or "k-hierarchy-cell" classes, so the event can be prevented.

There is one important caveat to consider with this approach: Only columns at the front and the back of the grid can be locked in place, so there needs to be validation to prevent having non-reorderable columns among reorderable ones.

Hello,

Just upgraded to 2022.2.802 Kendo UI for jQuery and noticed that when clicking on a row in a grid it correctly highlights it (e.g. dark blue), but doesn't maintain the selection when moving the mouse from the row. This appears to be a breaking change - at least for our code. Previously it would still be selected/highlighted when moving the mouse away from the row.

Cheers,
Nick

Original posted on the forum. Looks like someone else has this issue as well.

https://www.telerik.com/forums/grid-does-not-maintain-row-selection-visually-highlighted

When exporting all the lines in the grid with saveAsExcel the excel is formatted in the event handler when the ExcelExport event is fired.

I would like to have the exact same effect when calling the exportSelectedToExcel method.

Incorrect role as link is defined for header controls of 'Branches' table.

This article describes how to disable the resizing functionality for specific columns in a grid while all other columns stay resizable. This works fine, as long as the grid is not sortable: After the user tries to resize a non-resizable column for the first time, the cursor is set to "col-resize" every time a column's header is hovered, even outside the resize area and without trying to resize it. This DOJO demonstrates the described behavior.

We have found out that the DOM of grid column headers looks differently when the grid is sortable. Also, the style that sets the cursor is set on a different element and therefore no longer removed by the workaround proposed in the mentioned article.

This DOJO contains an adapted version of the workaround that fixes the issue.

Test Environment:

Subject says it all, this has to be a bug or something? I am having the user update what's in the grid and then on cellClose making an ajax call to save the value but it's not firing when the cell changes, only if it stays the same.

Here's a dojo showing off what's happening:

https://dojo.telerik.com/ekoLaZOm 

Bug report

Get a scenario where we have a Grid with the following configs:

1. There is a selectable column in the Grid
2. There are one or more locked columns
3. The reorderable.row value to true

Having the above configuration, try to reorder random rows. The value in the Drag Hint shows a number of files that is twice the number of the selected for reordering rows.

• Note: In a scenario with a selectable column to be able to reorder rows, we have to select these rows at first

Reproduction of the problem

1. Open this Dojo example
2. Select two random rows in the Grid by checking their checkboxes
3. Use the Contact Title column to start the row dragging(We need this column because the rows' reorder cannot start from a locked column)

Current behavior

The text inside the Drag Hint is "4 items selected"

Expected/desired behavior

The text inside the Drag Hint should correspond to the number of the selected rows. In the above scenario, the text should be "2 items selected"
