Provide an option to customize the tooltip that appears while dragging a task in the timeline view. 

The directive `kendoGridColumnChooserTool` does not work correctly when having columns which are grouped. See this example: https://stackblitz.com/edit/angular-r9duqpcn?file=src%2Fapp%2Fapp.component.ts

1. It shows that 0 items are selected ("0 Selected items") - This is incorrect because all columns are selected by default. In the example above, I would expect it shows that 4 items are selected.
2. When unselecting an item in the list (popup), it does not actually hide any column.
3. When using directive `kendoGridToolbarTemplate` with `kendo-grid-column-chooser` component, it works as expected. I would expect that `kendoGridColumnChooserTool` directive would work (behave) exactly the same way.

Hi ,

I want the kendoGridFocussable to apply the FocusableDirective on an anchor tag. This should allow the user to reach the anchor element using only the arrow keys without pressing Enter. (Example : Please, check out the following StackBlitz demo: https://stackblitz.com/edit/angular-rqqzam)

Uzma

Hello.

Provide support for the "kk" format in the DateInputs components.

https://unicode.org/reports/tr35/tr35-dates.html#dfst-hour

Demo

Currently, there’s no way to add a placeholder for the filter input in a DropDownList when filtering is enabled.  It would be a great enhancement to create a component that provides a placeholder for the filter input.

It might be a formatting issue on my end

momentjs is a widely used date library which makes handling dates much more comfortable, and all Date components should support it

Hello,

When I try to delete all grouping manually by setting an empty group array, datas are disappearing. The grid datas are empty but reappears if I set grouping again. Also I could see data if I scroll down but I can't see any if I haven't enough lines to do so.

In attachment you could find a demo based on the "Collapse All with Grouping" tutorial.

Should be useful to decide where to align every single button of the toolbar center/left/right (or at least every button in the toolbar left or right).

This feature should be granted combined with the overflow option, in order to have a responsive behavior.

Hi, 

Please provide a feature like the following: https://demos.telerik.com/aspnet-ajax/scheduler/examples/creatingappointmentswithdraganddrop/defaultcs.aspx

Thanks and regards

If you expand a tree node with 1000 items in it, and that tree has an ng-template the performance is very poor. It takes 7 seconds on my machine, see here https://www.telerik.com/forums/slow-treeview-with-large-datasets

Please add virtualisation to the TreeView so that not so many DOM elements (and therefore ng-templates) need to be created.

First of all, thank you for providing the state management feature. For me it's one of the most important features of a grid component.

But unfortunately it fails to restore the columns state. This is because each time a grid component and it's columns are instantiated, new IDs are created for the columns. When loading state the columns are identified by their IDs.

When a column is persisted with e.g. id 'k-grid-column-1' and the grid will be destroyed and re-created, then the new column ID is not identical with the old one. Thus restoring the column's state will fail.

Please have a look to this StackBlitz example: https://stackblitz.com/edit/angular-vauqyshn?file=src%2Fapp%2Fapp.component.ts

A possible workaround is to save also the column's field property and later use it to re-map the saved id to the new id.

A better solution may be to extend the GridColumnComponent with something like a "PersistenceKey" property, which will be used for identifying a column. A directive may also work. Otherwise generating non transient unique ids for the grid columns will also work.

Best regards,
Holger

Hello,

I tried to implement this new feature : https://www.telerik.com/kendo-angular-ui/components/grid/scroll-modes/virtual#controlling-the-expanded-state-of-all-root-level-groups

You can see in the demo that if you remove all grouping, the content is now limited to 50 lines instead of displaying the whole 1000.

I found a workaround by expanding all before removing the grouping but it is not very user friendly.

If you can patch it ASAP that would be great. 

And thank you to finally have pushed this long awaited feature !

When setting the Checkbox component to disabled while the form is marked as touched, the k-invalid class is applied to the checkbox control.

That's because of the implementation of the isControlInvalid property:

public get isControlInvalid(): boolean {
    return this.control && this.control.touched && !this.control.valid;
}

According to the Angular source code:

    /**
     * A control is `valid` when its `status` is `VALID`.
     *
     * @see {@link AbstractControl.status}
     *
     * @returns True if the control has passed all of its validation tests,
     * false otherwise.
     */
    get valid(): boolean;

So valid() returns false when `status` is DISABLED.

The `isControlInvalid`property should better implemented like this:

public get isControlInvalid(): boolean {
    return this.control && this.control.touched && this.control.invalid;
}
