Hi everyone, 

i have a kendo Grid with columns virtualization enabled. It works perfectly but comes a weird behaviour when I add aggregate columns.

The problem consists in the constant relocation of aggregates cells values when scrolling horizontally the grid, i.e aggregate cell keeps changing column : the more you scroll, the more it jumps from a column to another.

I provided this jsFiddle sample to help you reproducing the problem.

Keep scrolling horizontally and keep an eye on "Field6"  and "Field8" columns where aggregates have been configured and you will see that the corresponding aggregates values will constantly go on wrong columns.

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.

Hi Team,

I'd like to request an event to allow for the user to dynamically create a new filter based on the field and type instead of using just columns.filterable.ui.  

Thank you!

Hi Team,

I would like to request a way to change the sort order with the built in API for the mixed sortable Kendo UI Grid.  

Thank you!

Hi Team,

I would like to request the detail arrow column to be configurable for placement to the right of the Grid without applying RTL support. 

Thank you!

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.

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 Team, 

I would like to request an attribute property similar to this one which will allow for easier modifications for the group header columns. 

Thank you!

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.

Hi Team,

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

Thank you!

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.

I want to have checkboxes in group header as shown in the below example.

https://dojo.telerik.com/eKUzITAH/41

Once I click on the group header checkbox, the child group headers under the clicked group header and the data rows inside it should get checked and when it is unchecked all the datarows under the group header should get unchecked.

Individually if I check and uncheck a checkbox in the datarow,the parent group header should get checked if all the datarows are checked and should get unchecked if any of the data is unchecked under that group header.

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]

Bug report

When applying GroupPaging with local data using a Kendo UI Grid with AngularJS, the error message Uncaught TypeError: Cannot read property 'hasSubgroups' of undefined' appears upon expanding a parent row.

Reproduction of the problem

1. Go to this Progress Kendo UI Dojo.
2. Attempt to expand the row.

Current behavior

Currently, the UID for the group is not matching the group row's UID, and the error message appears.

Environment

• Kendo UI version: 2021.1.224

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

Only two specific things that I've found lacking: 1) There doesn't appear to be any functionality for Kendo UI (jQuery) that allows for easily adding new values to a multi-select, which the Telerik RadComboBox appears to have. (E.g., for an email "to" field, selecting from existing contacts or adding a new address.) 2) The responsiveness (cell-phone-friendliness) of the Kendo UI Grid is extremely lacking, specifically if allowing for multiple rows selection. (Namely, trying to scroll down the grid instead selects the rows you swipe over, so you're unable to scroll down to see rows off screen.)

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.

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

The Grid is filtered initially and no records are displayed. When a specified filter is cleared through the column filter menu, the column with the checkbox filter menu does not show any checkboxes and there is an error in the browser console.

### Reproduction of the problem

1. Create an initially filtered grid and enable the checkbox-filter menu on the first column.

2. When the grid is loaded and no records are displayed (based on the applied filters), clear any of the filters manually through the column menu.

3. Click on the column menu of the first column.

4. An error is logged in the browser console. The checkbox-filter menu contains no options, but the column has data.

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

### Expected/desired behavior

The options in the checkbox filter menu should be loaded properly when any column filters are reset.

### Environment

* **Kendo UI version: 2021.2.616
* **jQuery version: 1.12.4
* **Browser: [all]

When the autofitcolumn method is used together with multi-headers and hidden columns, some of the columns are either not visible at all or shrunken.

The problem can be observed in the following Dojo:

https://dojo.telerik.com/EJezUyeg 

The CompanyName column should be visible, however it is not. If the example is ran in fullscreen, the column will be visible, however it will shrink if the Browser window gets smaller.
