Currently, the pageSizes option of the available Grid's PagerSettings only allows passing a boolean or a number array as possible values. Thus, at the moment, the Grid component allows displaying an "All" option in the pager by implementing a kendoPagerTemplate:

• https://www.telerik.com/kendo-angular-ui/components/knowledge-base/grid-pager-all-option 

It would be great if an "All" page size option could be set directly through the settings of the pageable property by having the ability to pass a PageSizeItem array to the pageSizes option, similarly to how its done in the standalone Pager component:

• https://www.telerik.com/kendo-angular-ui/components/pager/api/pagercomponent#pagesizevalues.

Current behavior
The grid component already has the functionality to resize and reorder columns by the user, but is missing functionality for saving an restoring columns configuration, so that changes done by the user are lost after a page change.

There is the Persist the State article in the "How to section" in the documentation, but the described solution is only applicable when adding grid columns by using *ngFor. When defining columns in the markup, due to extensive usage of templates (kendoGridColumnMenuTemplate, kendoGridFilterMenuTemplate, kendoGridCellTemplate, ..), there is no reasonable solution available.

Expected behavior
Provide methods, similar to the jQuery grid, to save and restore columns configuration. This should at least include the column's order, width and sort.

PS: This is not a duplicate of the feature request Add persistent state for grid (and other components). The latter one has been marked as "Completed" but does not include the needed functionality.

If you click the first 2 cells in column "UnitPrice", the first one reports column 2 (which is correct), the second reports column 1.

I suspect rowSpan causes this, rows without rowSpan seem to work.

Provide a built-in feature to collapse or expand child columns of the group column similar to ag-grid.

Proposal

CellCloseEvent<T> should provide dataItem: T

Why

Currently the CellCloseEvent dataItem is typed as any. This could be the default, but adding a generic type here would allow strong typing in the event handler.

Currently the Grid Filter menu logic is "and" and there is no built-in option for changing it even when using the configurable filter menu components in the Filter menu template.

It would be nice having an option to configure the default logic as well as to limit the list of options to only "And"/"Or" or prevent the end user from changing the programmatically set filtering logic.

As a workaround for setting the initial logic, the developer can use the logicChange method, e.g.:

https://www.telerik.com/forums/default-filter-menu-logic#4935605

Currently, the Selection feature behaves strangely with the Keyboard Support enabled, see [demo](https://plnkr.co/edit/hTOg7Flx5Fnm63jJ6CgX?p=preview):

* Enter, Ctrl+Enter and Shift+Enter select the rows, but do not function if the cell has focusable components
* Space works only on the checkbox column
* Ctrl+Space, Shift+Space do not work at all

Ideally, the Grid should support the following shortcuts when the Selection and KB Navigation are enabled:

* Select the current row on Space, regardless of the cell content
* Support Ctrl and Shift modifiers for Space

* Shift + Up/Down Arrow for adding/removing the next/last row to the selection.

Similar to the TreeList KB navigation:

Please provide support for spanned columns with multi-column headers combining the already existing features:

https://www.telerik.com/kendo-angular-ui-develop/components/grid/columns/spanned/

https://www.telerik.com/kendo-angular-ui-develop/components/grid/columns/headers/

Overcoming the last listed limitation would be nice:

https://www.telerik.com/kendo-angular-ui-develop/components/grid/columns/locked/#toc-known-limitations

Currently when I click the horizontal scrollbar button which is present at the left side or right side of the scroll bar then the columns are scrolled as a regular table.

It will be nice to move from one column to another column instead.

Hi Team,

Requesting a feature to grid rows merge like the below example,

Thanks!

Currently, the NumericFilterMenuComponent has a default filterDelay of 500ms. So, in some scenarios where a value is entered and the Enter key is pressed very quickly, the component may not be able to catch the new filtering condition and create a new filter descriptor with the entered value.

It would be great if the component is enhanced to take into account the last entered value in such scenarios despite the defined delay. 

Hi,

It will be a nice feature to have the ability to customize the drag hint of the built-in row reordering similar to the hintTemplate.

It would be nice to have a feature to remove some operator from the grid filter built-in functionality as a global setting so that they apply across all grid columns without needing to repeat this customization for each column.

I understand that Kendo supports this functionality as described, but my expectation is to configure it as a global setting rather than on an individual basis. This would significantly simplify configuration in cases where multiple grids or columns are involved.

Add a locale formatting option to the Grid pager elements, similar to the functionality available in the DropDownList within the Grid pager.

Hi, Team!

I would like to request the introduction of the Ctrl + A keyboard shortcut as an approach for selecting all rows inside the Grid component.

Could we have a turnkey solution which allows to disable a row selection which takes care of disabling only the relevant selection checkboxes and handle properly the "Select all" checkbox state (in header).

With CheckboxColumnComponent field which allows providing dataItem field name or predicate function.

<kendo-grid-checkbox-column showSelectAll="true" disableSelection="isDisabled">
</kendo-grid-checkbox-column>

<kendo-grid-checkbox-column showSelectAll="true" [disableSelection]="isDisabledPredicateFunction">
</kendo-grid-checkbox-column>

OR

If you don't want to add more selection concerns into CheckboxColumnComponent this field could be specified in your SelectableSettings as well:

public selectableSettngs: SelectableSettings = {
    enabled: true,
    checkboxOnly: false,
    mode: 'multiple',
    cell: false,
    drag: false,
    rowEnabled: mySelectableRowPredicateFunction
}

rowEnabled field could something like this:

export declare type RowEnabledSelectionFn = (context: RowArgs) => boolean | boolean;

export interface SelectableSettings {
    //...
    /**
     * Determines if row selection is allowed.
     *
     * @default true
     */
    rowEnabled?: RowEnabledSelectionFn;
}

Thank you
