We need the ability to merge grid rows with the same values (see attached). This is a feature our customers have come accustom to with our Windows UI and the Developer Express toolkit. I understand I can manipulate the rowTemplate to achieve similar results but it is my understanding this will cause issues with row selection, editing, etc... Is this something that can be introduced in the future?

While the grid pager is enabled, if set a new datasource of this grid via javascript ( grid.setDataSource(new kendo.data.DataSource(obj)) ), multiple pager numbers wrapper wil be created. And this makes pager layout wrong.

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

Hi Guys,

It would be nice to have GridColumnAttachment field for Kendo ui grid like in Telerik RadControl

It would be great if user can format all the number is pager with 'N0', like following.

'page 1 or 1,200 pages'

'1,200-1,300 of 1,500 items'

The current implementation of the DataSource only allows for footer aggregates during the fetch of data. When we f.i. use virtual scrolling in a grid for each fetch of data from the server we also have to calculate the aggregates. In many cases that is a time consuming process. F.i. we have a project that has an activitylist containing over 100.000 rows. We only show 25 rows with skip(page) and take(25) but on each roundtrip we calculate the aggregate for all 100.000 rows.

A better solution would be to get the aggregate asynchronous from the data fetch and only fetch the first time and when a change has taken place in one or more fields that have an aggregate result.

With the kendoGrid, if no columns are specified, all columns are automatically rendered. However, dates (at least, I have not tested other non-strings) are rendered in non-human-readable form (at least if they are from SQL Server).

Since date rendering is tied to culture parameters, it would make sense to specify culture at the grid object level and have dates, currency, etc. render according to that. It would also be great to have filters setup for these different types applied to dynamic columns.

We use the Kendo Grid with a DataSource connected to an OData service. We also use the OOB Kendo Grid functionality to hide columns in the UI (column.hidden = true). Through testing we found out that the Kendo grid does not use the OData option of selecting specific columns for retrieval. The grid will request all columns for a table, which leads to overhead in the amount of data sent from the server to the client. We sometimes have tables with 50 columns, for which only 10 columns are shown.

I know it has been rejected and I think it was not given any good reason.  Managing dropdownnlist in datagrid is a pain and just not having pair value/text is missing and using "foreign key columns for this" is not an acceptable answer for me.


It should be a basic type of column, not a template, and show a text but be set as a value because we use the text for translation purpose, so the text cannot be the value. Even with the help from your technical support, when you have many of them in one grid, it's takes a long time to code and maintain. Such a common and basic feature should be with the basic controls of the grid.

Support custom attributes for Kendo grid
When kendo grid is applied to an html table, all custom attributes that have been applied to rows, cells or data within cells is lost.  It would be great if you could preserve these.  I realize the challenge in distinguishing between what is considered a *custom* attribute.  Perhaps enforce specific naming conventions and support preservation of those.  Perhaps anything starting with "data-" is preserved?

If an Ajax validation (sync or async) is called by a custom validation, kendo grid navigation should move to next or previous cell by pressing once tab or shift + tab key, if it's valid -as normally- or cancel edit if it is not.

By Default the Grid filters for text columns only do the following comparisons; Equal, Contains, Starts, Ends (& Not's)

We are missing: Greater Than, Less Than, GE & LE.
Given the alphabet is ordered, it is reasonable & desirable to add these 4 comparisons to text as well as numeric & date columns. 

This empowers a filter like (Surname >= "L" AND Surname < "O")  so we can find all customers with Names starting with L, M & N

When "Clear Filter" in grid column filtermenu is clicked,grid's dataSource's filter method is called even though the grid is actually not filtered with that field yet. eg. Load this page http://demos.telerik.com/kendo-ui/grid/remote-data-binding and directly click clear filter of any column field. It'll query the remote data. I don't want this behavior. Because the grid is not filtered by that field yet.

We have implemented custom 'search' functionality for Kendo grids, which uses column filtering 'behind the scenes'.  Without a hacky workaround, we are having a problem where modifying the filters list behind the scenes will trigger the filter indicator on the columns. It would be great if there was some kind of 'silent' filtering that we could add for this instead of having to write a completely custom query for searching.

We are not using an editable grid for this scenario.  The Kendo Grid needs to have its existing filter and sort cleared which should not result in two unnecessary reads to the server and then do a read on the datasource to get the newly added row.  We then return the data from the server in descending order by Id so the new row is at the top of the grid and selected.  If the sort for a default view and add are the same, no issues, but when they are not, the work around is complex.  What are the options and how can we make this simple task simpler to code and maintain?

It would be nice to have an option to place the filter row in the table footer instead of the header. It is possible to move it in the DOM using JavaScript, but it breaks the functionality.

i have a grid with number column and the template is replace the number with a text according to the number, but the sort is according to the number which is not correct.
for example: data[ status: 1 , 2 , 3 ]  the template return Cancelled for 1 Accept for 2 and in Processes for 3. it shoul be sorted in that order: Accept ,Cancelled, in Processes but actually is sort like that: Cancelled, Accept, in Processes 

When scrolling is disabled for a grid and column resizing is enabled, resizing a column acts in a strange manner and attempts to size all columns of the grid.  I would expect that only the two columns on each side of the resize handle should have their widths altered.  Otherwise scenarios can occur where you are completely unable to resize columns.  If this would not be default functionality, I would at least suggest a flag to enable it at grid setup.
