Virtual scrolling for GridColumnMenuCheckboxFilter

Request:

- provide a boolean property "virtualScrolling" on component GridColumnMenuCheckboxFilter which allows rendering a large list of filter options without delay

Discussion:

- https://www.telerik.com/forums/gridcolumnmenucheckboxfilter-virtual-scrolling

Use case:

- there are a lot of options to filter already in memory

- the filter dropdown has to open quickly (it opens slowly now, because there are so many options)

- after opening, the user sees a huge list (i.e. a long scrollbar)

- so he starts making the list of options smaller using the search input

Here's a screenshot with 100 options. 

 

Alternatives:

From a developer point of view I think a scrollable filter is the most convenient way to handle the problem.

An alternative would be to provide a handler whenever the user selects a combobox in the GridColumnMenuCheckboxFilter. Then we could cut the number of options after a threshold and an option / combobox labelled "show more". When this is clicked, the filter options are re-rendered, the lists gets longer - and the user will get annoyed and will making the list of options smaller using the search input.

An other alternative would be to have a possiblity to force the user right away to use the search box. Instead of showing the list of checkboxes a text would be shown: "1258 options. Please refine your search input." But this would be a more invasive option.

Hello, Christian,

Thank you for the feature request and all details around it.

We will monitor the interest and plan accordingly.

Until it is implemented I can suggest checking the following knowledge base article showing how a custom CheckboxFilter can be made, as this can help to integrate some of the suggestions in the current version of the Grid:
