FlowListView - ContextActions for each item separately about dltoolkit.forms.controls

[daniel-luberda]

It's simple. FlowListView doesn't use ViewCell as a base, but a standard View. So just subclass View in your custom platform specific cells. That's all.

However it uses its own ViewCell under the hood. See this: https://github.com/daniel-luberda/DLToolkit.Forms.Controls/blob/master/FlowListView/DLToolkit.Forms.Controls.FlowListView/FlowListViewInternalCell.cs

Hello Daniel

I am using FlowListView and I use my custom views without classic ViewCell. I need to implement contextual options in xaml as demonstrating in https://developer.xamarin.com/guides/xamarin-forms/user-interface/listview/interactivity/#XAML

As FlowListView does not use classic ViewCell , I am unable to reach its ViewCell.ContextActions property. https://developer.xamarin.com/api/type/Xamarin.Forms.Cell/#Public_Properties
How would you suggest to use your customized FlowListViewInternalCell that extends ViewCell in order to access this property ? (By xaml or by code)
Thank you by advance for your help !

@julyorange I could expose that, but the problem is ContextActions will be called for the entire row, not single item (items are implemented inside ListView's row).

You could access all ViewCell properties easily by creating custom renderer for FlowListViewInternalCell. Did you try that?

@daniel-luberda Thank you for your answer and justification about entire row.
Indeed, a ViewCellRenderer on FlowListViewInternalCell enables me to access ViewCell object, but this object always targets the entire row of base ListView but not single items on "grid" FlowListView .
I did not manage to see contextual menu appears by setting ContextActions in my custom renderer. :(
Correct me if I am wrong but it seems that it's not possible to implement contextual actions on a single item when I am using FlowListView as a grid ?

[daniel-luberda]

@julyorange You're right, it's not implemented.

but this object always targets the entire row of base ListView but not single items on "grid" FlowListView .

FlowListView inherits from ListView, which is based on native controls for displaying list views, they only do support context actions for a single row - that's the problem. You could use something like ACR user dialogs for now though.

I'll close this one as Xamarin.Forms.ListView doesn't support that.
