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!

### 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

In the spreadsheet there is a way to delay repainting til bulk editing is complete.  Grid does not have such a mechanism easily accessed, however with a  grid with a large number of rows, inserting multiple rows takes a long time as each row insert triggers the change event.  It can be worked around but would be better if it was supported like spreadsheet.

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. 

How to implement SearchRow in RadGrid for ASP.Net similar to SearchRow in WinForms RadGridView

The SearchRow in RadGridView WinForms is extremely good.

https://docs.telerik.com/devtools/winforms/controls/gridview/rows/search-row 

How can we implement the same in Kendo UI RadGrid?

The grid does not have a auto generated Serial Number or Row number column built in. Although this functionality can be custom built, but I feel this is a basic thing and when you have to use the grid in different places in your program, then duplicating the same code for a simple functinoality sounds over killing and maintenance overhead.

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

 

The existing configuration(filterable.extra), can only support 1 or 2 input from the UI. It would be great if multiple filter criterion input from the grid UI will be supported in the coming releases.

The popup dialog used by the Grid control does not match the Dialog control. With the same theme applied, the title bar is different (height, font size, and close button), and the button bar footer layout is completely different (button shape, size, and location).

By default, dialog look & feel should be consistent across controls using the same theme.

We have a project where we need the infinite scroll, column sorting/filtering, and remote data enabled.  We are having some issues with sort and filter.  For quick reference, I used the grid demo and changed it to reflect our configuration.  The problem is the grid fires the read command twice when we have loaded more than one page of data. No issues when we have only loaded the first page.

https://dojo.telerik.com/UDoREFID

To reproduce:

1.  Open Chrome

2.  Load the page

3. Hit run

4. Open Developer Tool

5. Switch to the Network tab and filter by XHR only  

7. Click ProductName to sort. There is only one AJAX call.

8. Scroll to the bottom so it loads the next page. It made two AJAX calls

Please include exporting functionality of the Grid to CSV and XML formats for the Kendo UI for jQuery.

At the moment, Remote Validation on the grid does not work with incell editing.

I would like to see this restriction removed.

Normal validation works with incell editing; however, the remote does not. I should not have to change the appearance and functionality of the grid from incell to to inline just because the standard validation is insufficient.

I appreciate that this is not an easy change, but hope you are able to give it some priority.

Bug report

When sorting is enabled for a virtualized Grid with local data, in some cases the Grid does not show correct items when sorted.

Reproduction of the problem

1, Open the Dojo example
2. Scroll to the bottom
3. Sort the Grid

Current behavior

Only the last 3 items are displayed. (screencast)

Note: The issue does not occur every time.

Expected/desired behavior

Enough items to fill the Grid height should be displayed. There should be no blank space without records.

Bug report

When the persistSelection option of the grid is disabled and several rows are selected across several pages, the selectedKeyNames() method returns all IDs instead of only the ones on the current page.

Reproduction of the problem

1. Set persistSelection to false.

2. Select several rows across several pages.

3. Call the selectedKeyNames method

4. Observe that IDs that are not on the current page are returned.

The steps can be replicated in the following live demo:

### Bug report

When the loaderType is set to "skeleton" and the grid is a hierarchy, the skeleton placeholder for the last column is not rendered.

### Reproduction of the problem

1. Set the loaderType to "skeleton".

2. Set a child grid to create a hierarchy.

3. Load the grid.

4. The last column has no skeleton container.

There's a discrepancy between the header and rest of the rows when the selected rows are coppied and pasted in Excel.

### Bug report

When the grid uses GroupPaging, Locked columns and one group spans over two pages, the header rows on the second page are misaligned.

### Reproduction of the problem

1. Create a Grid with GroupPaging and Locked columns.

2. Expand a group that should span over the next page.

3. Navigate to the next page.

4. Rows are misaligned.

### Bug report

When the Kendo UI Grid widget in "Popup" edit mode has more than one level of grouping, and when the adding of a new record is canceled, the group headers of the empty row are not removed.

 

### Reproduction of the problem

  1. Group the Grid by 2 columns;

  2. Click the "Add new record" button;

  3. Click the "Cancel" button in the Popup form;

  4. The empty row for the new record is removed, but the group header of the first group remains. 

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

 

### Expected/desired behavior

The group headers of the empty row should be removed when the adding of a new record is canceled.
