Hi, Team!

I would like to request functionality that would allow the developer to determine whether single or multiple items are expanded at the same time inside the Grid's Column Menu.

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

It would be helpful to have a filter option inside the ColumnChooserComponent.

In some use cases we have around 30-50 items inside the list, it's hard to scroll through the small window to find your entries. 

A simple textbox to search through the entries would be enough.

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

Hi, Team!

I would like to request functionality that enables me to implement a feature allowing the users to drag and drop multiple rows simultaneously inside the Kendo UI for Angular Grid.

Hi Kendo Angular team,

It will be a nice improvement if there is an option to set a specific type for the Grid data item and the templates. This will allow checking the types inside the templates when fullTemplateTypeCheck is on.

Please provide row virtualization as addition to the current virtual scrolling functionality.

Current behavior
Virtual scrolling is currently tied to the pageSize. This is not always desirable as page size can be much higher than the visible area to optimise for network latency.

For example if the pageSize is 200 rows and the grid is only 10 rows high we'll be rendering 190 more rows than needed at initialization time.

Expected behavior
Virtual scrolling should include an option to render only the visible rows at any given time.

When filter popup is opened, it need to be closed by click outside of it

However, popup is closed only after second click outside.

After popup was opened and closed for the first time - next times everything works correctly, so it can be reproduced only after refreshing the page with this component

It can be reproduced in example in your documentation: https://www.telerik.com/kendo-angular-ui/components/grid/filtering/filter-menu/#toc-custom-filters/

Please provide a how-to example that demonstrates how to move from one cell to the other using "Tab" in an editable Grid with virtual columns.

When there are more columns than are visible within the viewport the columns are virtualized which is expected.

However, when editing a row and we want to tab through the fields, we can only tab through the fields that are in the viewport and once we tab from the last viewport field our focus leaves the grid entirely and we cannot navigate to the remaining fields at all.

Thank you.

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/

There is already checkbox column and check/select all on header level, but it will be great to see checkbox on group level header too, so we can select/deselect all items in the group.
