[RadListView] Using FilteringFunction, it's not possible to know the filtered items length #1341

Open jscti opened 4 years ago

jscti commented 4 years ago

Nothing much to say..

I have a SearchBar + RadListView + filteringFunction

When I Type on the searchBar it filters the RadListView items, but now I want to show a "list empty" label when the filters outputs no items.. But I can't as the API doesn't seem to provide me this information..

@jscti you can add your own logic that extracts the filtered array length - I see no issues with that.

@NickIliev

What are you talking about ?

I am using the Radlistview API with 2 inputs of its own API :

Now, like that, there is no possibility to know the filteredList length that is internaly processed by RadListView ... => So feature request : RadListView api has a public items variable, and I just think it should also have a filteredItems public variable.

And yeah I could have my own filtering logic but what's the point when RadListView already try to do it .. and cover my needs at 99% ? (and I think the last 1% of this issue is pretty common need, not something exotic)

Thanks

@NickIliev Any thougts on this? Will you reopen ? TLDR: there is no way to know how many items are actually shown on listView after filtering using radlistview filtering api ..
