Thanks for all your help, it really is appreciated.

You fixed the listbox highlight colour issue, only the reversion to blue for a selected item in the listbox remains.

I may have to pursuade the client that this isn't an issue given that the highlight colour has been fixed by you.

Thanks again!

Unfortunately WebForms doesn't always use the same methods and properties for controls as a .Net Framework website (this site is over 20 years old).

There are a lot of differences between how the controls work and some that have extended properties, etc, in WebForms have fewer methods and properties in a website project.

Also, I'm working on an old site coded entirely in Visual Basic.

I created a new Visual Basic Web Application (.Net Framework) with an Empty project template to try the C# code (converted to Visual Basic) in the updated solution, but it doesn't work.

The listbox still uses the Chrome default colour.

It's a web site (e.g. a Web Project), not WebForms or MVC.

I'm using .Net Framework v4.7 for a web site, with Google Chrome as the browser (I've also tried FireFox too).

Yes, I thought I might have something else interfering with the solution you suggested, so I set up the .aspx page with just two objects, an '<asp:listbox>' and an HTML '<select>' control.

With all other CSS eliminated and just the CSS for the 'listbox' (with the various options) the '<select>' list box works fine - when the item is highlighted it's in the correct colour, but the <asp:listbox> doesn't work in the same way, it retains the Chrome Blue background for the highlighted item.

Finally, I noticed that in the CodePen.io example, when you select an item in the list, then go back to reselect another item the list, the original item is already highlighted in blue, even though none of the code refers to blue for a selected item. This is why I'm thinking that it's a browser issue.

Thanks for the example.

I think the problem is that, as stated in the question, I'm using an <asp:listbox>, not an HTML .

Perhaps it's the ASP.Net implementation of the listbox that prevents the CSS from working?

No, sadly that doesn't work either.

Adding option:checked:hover with the box-shadow etc doesn't do anything to the items in the listbox when they are highlighted because the mouse is over them. Google Chrome Blue still rules for each highlighted option on the list.

Ah, I wish it was staring at me.

This doesn't do it, the colour of the highlighted item (as the mouse moves up and down the list contents) remains stubbornly in the blue of Google Chrome and doesn't change.

Unfortunately this changes the colour of all the items in the listbox.

I only want to change the colour of the item highlighted in the listbox when the mouse moves over it.

Apologies, I've updated the question with the inspection details

Unfortunately these solutions are for a complex javascript solution whereas the .Net Framework 4.5 already has the solution in the form of the '.frozen' property of the GridView Column, I just can't get it to work.

I've checked that IIS is running v4.5 - it shows v4 when the page fails to compile, but I understand that's normal, for some reason IIS error messages show v4 even if v4.5 is being used.
