Using the MobileView AngularJS directive throws an error upon initialization. This is a regression from 2019 R2 release.
I know that Kendo Spreadsheet works like most popular Spreadsheets (Excel and Google Spreadsheet) where, if you copy or drag and paste values from cells, you will copy also the styles, validations, etc from that cell to the new one (unless you select "paste values only" in a context menu or ctrl + shift + v). It would be awesome if we can set how this works by configuring a property in the Spreadsheet configuration, something like pasteValuesOnly: false/true or even more complex with an object where you can choose if paste values, validations, formulas, styles or whatever. Also you could attach this functionalities to a context menu (as Google Spreadsheet does) and be able to paste everything, values only, format only, formulas or data validation.
It would be nice to have the option for a single filter input that searches all columns on the Grid. I was able to implement my own custom solution but having to apply that to every grid in my app is cumbersome. I understand the importance for the flexibility side of having each column with its own filter box, but for simpler apps this is overkill and a single filter box is enough. The column component already has the [filterable] flag so this can possibly be used to exclude any columns if necessary. I was thinking of something similar to what is an out of the box feature for the Datatables JS plugin https://datatables.net/ Default search box that searches everything. Very simple to use and understand for basic users or when your application only calls for something that simplistic.
