General Information:

As tagged, this code is in c#, using WPF, with target framework .NET Framework 4.5.

Note: This is my first try at implementing MVVM, so comments about best-practices i'm missing will be appreciated (although this is not the main subject of this question).

Question:

WPF with a ListView and a Button. The Button removes items from the ListView.

ListView (View) ---> RemoveStringFromList() (ViewModel)

The above works. My problem is with highlighting.

I want to be able to remove a string from the ListView, and after removal highlight a different Item.

My initial thought was that by using a Property (SelectedItemProperty) that binds with the ListView's SelectedItem property - the highlighting will be automatic.

But in practice, the SelectedItem property binding works - as i can keep pressing the Button and remove items that became the SelectedItem per the logic implemented in the SelectedItemProperty setter - but although they are selected code-wise, they are not highlighted.

Code:

This is on a new bleeding edge ubuntu installed laptop where I also installed all the latest packages and tools.

The jupyter notebook also doesn't display the asterisk * when busy and execution index.

This might seem trite but I'm very used to the way notebooks work and without the order of execution and the busy asterisk I'm slowly losing my grip on reality.

Especially strange is the fact that I googled the hell out of this but it seems no one has encountered or reported it, hope its not an option I'm missing or something.

Note: yes, there are many, many posts regarding the issues of installing mysql for python, specifically for python3 (e.g. Troubles installing mysqlclient with pip3). Most solutions are done in a non-dockerized manner. I have also read the mysqlclient install guide. I am still struggling to get it to work

Here I am trying to install it to my docker image.

I'm learning Angular. I've created a custom month-picker from the scratch. It selects a range of months, no dates and no weeks. I wanted to highlight the range of months that'd been selected. You can think of primeng month picker but with range. I tried this, this and many other solutions but I failed. Here is my code:

monthpicker.component.html

Xcode does not highlight the selected instance in the editor.

Xcode - Text Editing preference has an option to enable/disable selected code/symbol highlight. And it's enabled there, but it still doesn't work in the editor.

Here is a snapshot of my editor code, with the selected instance.

I'm using Xcode 9.3-beta2.

Here is a similar question, but it's related to changing the highlight color: Make Xcode highlight selected symbol more

I got a RecyclerView and I worked it out how to highlight items when they get clicked and did like they tell here.

But this will highlight the item after it got clicked. I would like to have something like in a normal ListView. So the item should be highlighted while clicking. This is why I used OnTouchListener instead.
