Missing features of the ListView.

Tung Ngo asked 2017-02-05 11:40:41 UTC

Hello,

I have some comments about missing features:

1. Grouping is not available yet.
2. Binding - can ITG adding the binding functionality to the listview ?
3. Context menu : There is a conext menu for the listview. User may need the context menu for the Column header as well

I'm currently moving our VWG application to Wisej, those features are not available in compare with VWG. Do you have any plan to add them in the future version?

4. A HitTest function will be nice to have. I don't know it is possible with the listview or not. I see it available for the DataGridView

Thanks

Hi Tung,

Thank you for the feedback. Please find my answers below:

• Grouping can be added easily on the server side, but it's harder to render on the client since the ListView control in item view uses a virtual widget system. We can look at it after other controls in the TODO list. Let me know if having the properties and methods (without rendering for now) would help you.

• Yes we can add binding - we have a number of requests for this already and we are actively working on it.

• Added as a enhancement request. WJ-8004

• .Added as well for ListView in Details view only - WJ-8005

Best,

Luca

Hi,

I am trying to convert an application from VWG and one of the features I (and end-uses) need is grouping of items in ListView.

So, is there any plan to implement this feature ? and the schedule ?
-- If yes, will the title of the group clickable ? Have a [ + ]  or [ - ] icon, or otherwise allow to expand / collapse the group ?

Is there any sample to do that on server side, as mentioned above ?

Without this, I am hardly to make the conversion and/or end-users will most likely reject my idea of creating a new version (by WiseJ), that have less functions than the current production version (by VWG).

Thanks a lot.

Regards,
Felix CHAN

Hi Felix,

We can't add grouping of list items at the moment. The ListView in item  view uses virtual rendering (only the visible portion of the items is rendered)  and virtual scrolling since it's designed for large data sets, which makes it hard to add grouping. It is possible, but not on the immediate list.

Best,

Luca

Hi Tung,

MvvmFx includes a bound controls library that provides proper data binding for TreeView and ListView.

Debugging the BoundListView for Wisej I also noticed there is no grouping on Wisej ListView.

To make it crystal clear, BoundListView for Wisej does not implement grouping.
