@nghia-bui just to be clear - you don't want to be able to highlight any row in the list? Or better would be if you have a example app where I can check this directly.
If it is the case you can do the following:
- Create a customrenderer in this example I did it with iOS.
type MyListViewRenderer() =
inherit ListViewRenderer()
override this.OnElementPropertyChanged(sender: obj, e: PropertyChangedEventArgs) =
base.OnElementPropertyChanged(sender, e)
match e.PropertyName with
| "SelectedItem" ->
match this.Element, this.Control with
| null, null -> ()
| _ ->
this.Control.VisibleCells
|> Array.iter (fun v -> v.SelectionStyle <- UITableViewCellSelectionStyle.None )
| _ -> ()
- Export this Renderer
[<assembly: ExportRenderer(typeof<Fabulous.XamarinForms.CustomListView>, typeof<MyListViewRenderer>)>]
This way the renderer is going to work for every View.ListView
.
If you only want to modify one specific ListView then you need to create your own type as follows:
module TestListViewModule =
type TLV() = inherit CustomListView()
type Fabulous.XamarinForms.View with
static member inline TestListView(?items: ViewElement list, ?itemAppearing: int -> unit, ?itemSelected: int option -> unit) =
let attribCount = 0
let attribs = ViewBuilders.BuildListView(attribCount, ?items=items, ?itemAppearing=itemAppearing, ?itemSelected=itemSelected)
let update (prevOpt: ViewElement voption) (source: ViewElement) (target: TLV) =
ViewBuilders.UpdateListView(prevOpt, source, target)
let updateAttachedProperties propertyKey prevOpt source targetChild =
ViewBuilders.UpdateListViewAttachedProperties(propertyKey, prevOpt, source, targetChild)
ViewElement.Create<TLV>(TLV, update, updateAttachedProperties, attribs)
And to make it work for this specific type you have to change the export part.
In the following example just use the path to your type.
[<assembly: ExportRenderer(typeof<AllControls.Samples.TestListViewModule.TLV>, typeof<MyListViewRenderer>)>]
