Select slots programmatically in monthly timeline

Hello,

I am trying to implement some conditional selection of slots in monthly timeline of scheduler. I looked at an example provided here:
https://demos.telerik.com/kendo-ui/scheduler/timeline
and modified this example by adding the following code to scheduler definition (link to dojo snippet: https://dojo.telerik.com/eciQugem):

selectable: true,
change: function (e) {
var start = e.start;
var end = e.end;
e.sender.select({start: start, end: end});
},

Adding this allows to select slots in row 0 (by default - as expected), but I want to be able to select slots in any row. The documentation suggests I should specify resources in options.resources, but I have no idea what should I put there and having given it a few shots I constantly encounter errors. Could you provide me with an updated dojo example that shows how to achieve it?

Customizing the control that displays field selection.

Is it possible to change the dropdown for the field selection on this control? We have several "related" tables that can be filtered on and would like to group the fields on the table name & also allow for searching the combo with text input (ie: https://demos.telerik.com/kendo-ui/combobox/grouping).

Customization of the kendo.ui.Grid

I want to customize the kendo.ui.Grid for my application and create a base class kendo.ui.GridEx that inherits from the kendo.ui.Grid class. Everything works fine, except with columns.selectable (true). The check boxes appear, but the click events are not handled. Therefore the selection method does not work either (no rows returned).

Example: https://jsfiddle.net/chstorb/g3n5or69/

Group issue - The component doesn't refresh the change when manually change value

Greetings.

I am using the custom group functionality with two dropdownlist components, and I found an issue when I manually change the value from the first component to the second component and it doesn’t refresh the change.

I attach two images: one for the configuration and another to show the issue.

It happens in every dropdownlist component that has the same configuration. I don’t know if this is a bug, and if that is the case, how can be fixed?

Thanks in advance.

Formatting expressionPreview

Is it possible to alter the format of the expressionPreview?

When a date filter is applied, the preview looks like: "Date Is After 'Tue Jan 01 2019 00:00:00 GMT+0000 (Greenwich Mean Time)'" -- I'd like to be able to customize the displayed date format, something like adding "format:"{0:dd/MM/yyyy}" to the 'fields' object.

Thanks

Row hover action bar

Hi,

I'm looking to implement an "action bar" when a user mouse hover a row. Just like in gmail or outlook365 when a user mouse is hover a message, icons appear to delete, mark as read, ...

All I found as of now, is to reserve a column and with jquery/css show/hide the icons. I don't want to reserve a specific column for that. I want it to be on either at the beginning (left) or at the end (right) of a row and on top of the row. I attached an image to demonstrate what I want to do.

An ideas ?

Thanks

Forcing column width for narrow grids

In the column width page of the grid documentation https://docs.telerik.com/kendo-ui/controls/data-management/grid/columns/widths, it says:

When scrolling is enabled:

- When all columns have pixel widths and their sum is less than the width of the Grid, the column widths are ignored and the browser expands all columns.

Is there a way to disable that for certain columns? Some of my columns - especially the command column - look really stupid when the auto-resizing adds a bunch of whitespace to them.

Multiselect with checkbox.

Good morning I have to realize multiselect with checkbox.
The final result will be very similar to this:
http://embed.plnkr.co/OVPTCV/
This example, however, is very old and I noticed that with the 2018 version of kendo it does not work perfectly.
It is possible to have the same result using the version of kendo 2018 which seems to me to use different approaches. (eg tagtemplate)
