I had already made an entry in the Foum about it.

https://www.telerik.com/forums/is-there-a-way-for-percentage-column-widths

Link to the demo with the css workaround:

https://stackblitz.com/edit/angular-y8y55s

The main intention is that I want to be able to specify the column width in percentage values rather than fixed pixel values.

There are some edge cases that must be considered:

1. If columns are rearranged, the column width is taken to the new position.
2. If the table is grouped, the columns in the group remain aligned below the column headers.
3. If a column is manually resized, the behavior changes, the table is allowed to grow beyond 100% and gets a scrollbar.

I have a Grid with a command column for edit/remove buttons.

I also have a custom button that has to be hidden while the row is being edited, but there is no variable that exposes that state.

Please provide isEdited field in the kendoGridCellTemplate context.

Hi Team,

We need to add caption on grid table as explained here: https://accessibility.psu.edu/tableshtml/#caption

JAWS should read this caption on pressing T while selecting the table.

Can you guide us how can we add this caption!

Thanks,

Saini

A built-in option for enabling a second scrollbar on the top of the Grid like the following screenshot would be nice feature to have:

Please provide a frozen column separator as the one for the WPF DataGrid:

thank you

Please provide an [autoSync] option of the ColumnMenuChooser component as the [autoSync] option for the ColumnChooser component:

Thank you.

Hello Telerik,

We have implemented a custom reusable filter cell component similar to the example of the multi-select checkbox example from the docs. The difficulty using that example however, is that when the filter is updated, the other filters in the grid are removed due to the use of filterservice.filter. Because the CompositeFilterDescriptor can contain both filters and composite filters, why does the base filter cell component's base methods not allow a CompositeFilterDescriptor to be provided to the UpdateFilter method? 

    protected filterByField(field: string): FilterDescriptor;
    protected filtersByField(field: string): FilterDescriptor[];
    protected removeFilter(field: string): CompositeFilterDescriptor;
    protected updateFilter(filter: FilterDescriptor): CompositeFilterDescriptor;
    protected applyFilter(filter: CompositeFilterDescriptor): void;

Our method for implementing the multi-checkbox filter cell was to build a composite filter using 'Or' logic and each selected value added as a filter descriptor with operator 'eq' and the selected item value as the value of the filter, and use a similar strategy as the base filter cell component to add this composite filter to the filter service's composite filter. 

  private getSelectedFilters(values: Item[]): CompositeFilterDescriptor {
    const selected: FilterDescriptor[] = values.map((value) => {
      return {
        field: this.field,
        operator: 'eq',
        value: value.value,
      };
    });
    return {
      filters: selected,
      logic: 'or',
    };
  }

  public onChange(values: Item[]): void {
    this.selectedValues = values;
    const root = this.filter || {
      filters: [],
      logic: 'and',
    };
    this.removeFilter(this.field);

    if (values !== null && values.length !== 0) {
      root.filters.push(this.getSelectedFilters(values));
    }
    this.filterService.filter(root);
  }

If the base filter cell component allowed the CompositeFilterDescriptor type or the FilterDescriptor type in the updateFilters method, we could simplify the logic in our filter cell component to be similar to the patterns shown in the drop-down list filter component example, as shown below, but with a composite filter descriptor such as the one generated by the above getSelectedFilters function.

this.applyFilter(
      value === null // if value of the default item
        ? this.removeFilter(this.valueField) // remove the filter
        : this.updateFilter({
            // otherwise add/modify the filter for the field with the value
            field: this.valueField,
            operator: 'eq',
            value,
          })
    ); // and update the root filter

I think this would be a beneficial addition to the Kendo Angular2 product, as it would enable many more reusable filter components to be created more easily and also simplify/ enhance some of the existing examples you provide.  If you would like more information or the full multiselect-filter component, I would be happy to supply it.

Thank you!

Hello,

   You have this jQuery example: Binding to Kinvey Backend Services.  Do you have a similar example for Angular?  I cannot find one.  

Thank you.

Can you add "extra" field to FilterableSettings to allow the user to set extra globally for all columns in a grid? 

https://www.telerik.com/kendo-angular-ui/components/grid/api/FilterableSettings/

Currently, if I want to set extra to false for a column, I need to do something like this: 

<kendo-grid-column field="ProductName" title="Product Name">
   <ng-template kendoGridFilterMenuTemplate let-filter let-column="column" let-filterService="filterService">
     <kendo-grid-string-filter-menu [extra]="false" [column]="column" [filter]="filter" [filterService]="filterService">
     </kendo-grid-string-filter-menu>
   </ng-template>
</kendo-grid-column>

But it would be simpler if we can do filterable:{extra:false} just like Kendo UI for jQuery. https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/filterable.extra

Issue: unable to filter data by itself written filter handlers.

Current implementation:

/**
 * A complex filter expression. For more information, refer to the [`filterBy`]({% slug api_kendo-data-query_filterby %}) method.
 */
export interface CompositeFilterDescriptor {
    /**
     * The logical operation to use when the `filter.filters` option is set.
     *
     * The supported values are:
     * * `"and"`
     * * `"or"`
     */
    logic: 'or' | 'and';
    /**
     * The nested filter expressions—either [`FilterDescriptor`]({% slug api_kendo-data-query_filterdescriptor %}), or [`CompositeFilterDescriptor`]({% slug api_kendo-data-query_compositefilterdescriptor %}). Supports the same options as `filter`. You can nest filters indefinitely.
     */
    filters: Array<FilterDescriptor | CompositeFilterDescriptor>;
}

Where filter descriptor has next available fields:

export interface FilterDescriptor {
    /**
     * The data item field to which the filter operator is applied.
     */
    field?: string | Function;
    /**
     * The filter operator (comparison).
     *
     * The supported operators are:
     * * `"eq"` (equal to)
     * * `"neq"` (not equal to)
     * * `"isnull"` (is equal to null)
     * * `"isnotnull"` (is not equal to null)
     * * `"lt"` (less than)
     * * `"lte"` (less than or equal to)
     * * `"gt"` (greater than)
     * * `"gte"` (greater than or equal to)
     *
     * The following operators are supported for string fields only:
     * * `"startswith"`
     * * `"endswith"`
     * * `"contains"`
     * * `"doesnotcontain"`
     * * `"isempty"`
     * * `"isnotempty"`
     */
    operator: string | Function;
    /**
     * The value to which the field is compared. Has to be of the same type as the field.
     */
    value?: any;
    /**
     * Determines if the string comparison is case-insensitive.
     */
    ignoreCase?: boolean;
}

export interface FilterDescriptor {
    /**
     * The data item field to which the filter operator is applied.
     */
    field?: string | Function;
    /**
     * The filter operator (comparison).
     *
     * The supported operators are:
     * * `"eq"` (equal to)
     * * `"neq"` (not equal to)
     * * `"isnull"` (is equal to null)
     * * `"isnotnull"` (is not equal to null)
     * * `"lt"` (less than)
     * * `"lte"` (less than or equal to)
     * * `"gt"` (greater than)
     * * `"gte"` (greater than or equal to)
     *
     * The following operators are supported for string fields only:
     * * `"startswith"`
     * * `"endswith"`
     * * `"contains"`
     * * `"doesnotcontain"`

     * * `"isnotempty"`
     */
    operator: string | Function;
    /**
     * The value to which the field is compared. Has to be of the same type as the field.
     */
    value?: any;
    /**
     * Determines if the string comparison is case-insensitive.
     */
    ignoreCase?: boolean;

     /** --------------- ADDITIONAL DATA --------------- */
 
     /**
     * Manages filtering operations with data for single row
     */
    handler?: (dataItem: T) :  Observable<boolean> | boolean;
    /**
     * Filter name to display on grid
     */
    name?: Observable<string> | string;
}

Kendo Grids for Angular has the ability to remove operators by using `[showOperators]="false"`, however this keeps the button visible.

We would like the option to also hide/remove the clear button.

Hi Team

It would be very helpful if Grid allow to prevent focus on cell out-of-box, at the moment, we have to handle focusin event then set focus to other cell, however when using navigation keys or shortcut key, we need to handle differently depend on which cell should be focus next.  

Reproduction

- Use a grid with data coming from a service (or another source)

- Click the delete button (built in with the grid

It removes the element from the grid as soon as I click the button but I want to remove it only after confirming the deletion.
