The Custom() DataSource has capability to set the initial Page of the grid:

        .PageSize(20)
        .Page(4)

While the Ajax() DataSource does not. It would be nice if it gets added.

Currently, you can use the page() method for local or .Ajax() bound grid:
https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/methods/page

Or query:

https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/methods/query

At moment the "ForeignKey" method supports only predicates. Is it possible to implement a String overload (a screenshot is attached)?

Hi Team,

I'd like to request adding a configuration to the Kendo UI Grid or ExcelExport event which would be a setting to autofit the Excel sheet columns instead of changing the workbook.sheets.columns.autowidth. 

Thank you!

### Bug report

When the filter is applied through the search panel, the query (more specifically, the filter expressions) is not built correctly. This results in displayed rows that have values that do not match the value from the search panel.

### Reproduction of the problem

1. Enable Search panel and group paging of the grid.

2. Set a value in the search panel and group by a column.

3. Expand the group and verify that there are items with values that do not match the filter expression from the search panel.

Short video demonstration:

https://screencast-o-matic.com/watch/crXFlXVI3i0

### Expected/desired behavior

The returned results should comply with the filter expression built from the Search panel.

### TicketID:
_1543306

### Additional notes and explanation

The Search panel builds the filter expression with the logic operator "or". While this is correct when the actual query is further built from the data source's internals (group function of the kendo.data.js file), the filter will be built with the "or" logic instead of "and". This query has to be restructured in order to send two filter objects with the "and" logic. The first filter object should contain all filter expressions built from the search panel with the "or" logic operator and the second filter object should contain an expression with the operator "eq", the field by which the group is built, and the value. The two filter objects should be combined with the "and" logic.

Bug report

When the Grid's Group Paging is enabled and its content is grouped, the Multicheckbox Filter doesn't filter the group data correctly.

Reproduction of the problem

1. Run this REPL Example.
2. Group by a column for example „City”
3. Filter the Country column for example „USA”
4. Check the result for a specific City group

Current behavior

The group shows rows that shouldn't be included when the column is filtered properly

Expected/desired behavior

The group should only show the filtered rows

### Bug report

When the Grid filter menu is customized with a DropDownList, the initial option defined by using the "index" property is not set.

### Reproduction of the problem

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

### Expected/desired behavior

The DropDownList should be initialized with an initially selected option.

### Bug report

The Kendo UI NumericTextBox is not rendered properly when it is added as a custom column filter through the "columns.filterable.ui" option.

### Reproduction of the problem

1. Use the "columns.filterable.ui" and define a JavaScript function which initializes a Kendo UI NumericTextBox;

2. Open the column filter menu and type in the input;

3. The entered value is not visible.

A Dojo sample for reproduction (filter column "Age"): https://dojo.telerik.com/OFuYawuC

### Expected/desired behavior

The NumericTextBox is wrapped in an additional "span" element with class "k-textbox". It should be removed.

Is it possible to implement an option for the Telerik UI for ASP.NET Core Grid to change the default filter operator "eq" to "contains" when the Grid column checkbox filter menu is enabled?

For example:

columns.Bound(p => p.ShipName)
  .Filterable(ftb => ftb
    .Multi(true)
    .Search(true)
    .Operators(op => op
      .ForString(s => s
        .Clear()
        .Contains("Contains")
)));

//Filter expression:
filter: ShipName~contains~'test'

Hello Team Telerik,

we have a Grid with a Select column:

...
.Columns(c =>
        {          
                c.Select().Width(50)
....

We want to give users the ability to quickly group rows that are selected. However, grouping the Grid by the Select() column is not possible

When Batch update mode is set to true, Popup editing mode should write back the data to grid and not call the update actions directly upon confirming the popup editing window.

I have a page containing a grid, in the toolbar there are following buttons:

* Add

* Edit

* Delete 

When the user clicks Edit, the selected row is edited using the pop-up window. Alternatively the user can also double click the row to start editing. 

On the bottom of the page there is a Save and Cancel Changes button. The save changes must update all applied changes, the cancel button must undo them.

At current when Popup editing is used and the user confirms the popup window, changes are immediately written to the database. This breaks functionality of the Cancel button. Cancel will now only apply to deletes.

I need popup functionality because I have too many columns to use in-cell editing.

Telerik is ignoring the setting batch(true) when doing popup editing, so this could even be considered a bug instead of a feature request!

Is it possible to implement a method in the Read() configuration of the DataSource that will append parameters as name-value pairs to the query string?

For example:

.Read(r => r.URL(myUrlPath).Handler(myPageHandler).AddQryStrPairs(myNameValuePairsModel))

Currently, I am appending the parameters manually as follows:

.Read(r => r.Url(qurc.PageUrlPath 
 "?handler=Read&area=" +  TkgrArea + "&serviceType=" + qurc.ServiceType.ToString() + "&serviceTag=" + qurc.ServiceTag  + "&entityType=" + qurc.EntityType).Data("forgeryToken"))

With batch editing there are no indicators that the grid is "dirty" after you hit delete, but before you hit the save changes button. [Note, when a user edits a cell, the top corner display a small red flag letting the end user know the cell is dirty and has not been saved/synced to the database yet.] This should be added to let the user know the delete action has not been performed and is in a "pending" state until the save button is pressed. This would be very helpful for UX purposes.

In the meantime, I just apply my own "dirty" class to the save button so end users know to press it before leaving the page if they would like to keep their changes.

### Bug report

The localization messages for some of the default Grid commands are missing. They are translated in the kendo.messages.he-IL.min.js:

https://github.com/telerik/kendo-ui-core/blob/master/src/messages/kendo.messages.he-IL.js#L302

### Reproduction of the problem

1) Create a Telerik UI Grid and enable the commands Edit(), Destory(), and Create().

2) Set the client-side culture to "he-IL" and register the localization script for that culture.

3) The commands are not translated.

Here is a Dojo sample, where all available localization messages for culture "he-IL" are in place:

https://dojo.telerik.com/UvaMivaS

### Expected/desired behavior

The localization messages from the "kendo.messages.he-IL.min.js" file should be available for the Telerik UI Grid.

### Environment

* **Kendo UI version: 2022.2.621
* **jQuery version: 1.12.4
