C# how to make listview item uneditable if it is not selected?

Question

0.00/5 (No votes)

See more:

I have a listview with 20+ items. Each item has a datepickers and comboboxes.
When I select lets say the 3rd item, but moving the mouse over the 10th and click on the combobox, I can edit it but the change will be applied to both the 3rd and 10th items.

Note, i still need to be able multi items, but only in case they are selected.

Is there any way to disable item edit if it is not selected?

Is there any best practice?

What I have tried:

had no idea, and could not find any useful article on the net. (most probably the issue is with my search words)

What control are you using? The title says listview but the text mentions a listbox containing child controls. I'm confused - please give full type names.

need more specific information on the structure of your ListView. Why do you need multiple selection ?

this is a project manager tool. Imagine the items as files and i do need to perform certain actions on multiple files at once and in some cases only on one file.
But in my case if no item is clicked as selected or as described a different item is selected I can still click a different row's combobox and that will perform the changes to both lines.

See the example here: c# - How do you disable an item in listview control in .net 3.5 - Stack Overflow[^]

As you probably do not use checkboxes you can try the ListView.ItemSelectionChanged Event (System.Windows.Forms) | Microsoft Docs[^]

Another candidate might be the ListView.ItemActivate Event (System.Windows.Forms) | Microsoft Docs[^]

how is that article relevant to the OP's question ?

The example is with checkboxes, which might not be what he wants, but it shows how you can use an event to handle things.
