How do I allow the user to multi-check with the CheckedListBox through the 'shift' key?

Say that I have a CheckedListBox with items "1", "2", "3", "4", and "5" in that order and I want to select "2", "3", and "4" by selecting "2" then holding shift and selecting "4". Is there any built-in way to achieve this with the CheckedListBox control? I found an article on how to use the SelectedIndexChanged event to get close to this behavior, but though it checks multiple items, it does not show them as selected.

If there is an alternative control that I could use then I would be up for that as well.

There might be an easier alternative, but you could use a ListView, set CheckBoxes to true, HeaderStyle to None, and View to List.

Correction:

Should have been set View to Details.

In my actual scenario, I have a large list of file names that will be the data. If I use the ListView, how do I set it to only be vertically scrollable and only have a single column of items?

Now that I think about it more, a ListBox is probably what I need. There's no reason to have checkboxes. They just need to select some files from a list. Thanks for the help though. Your answer would work for the test scenario from my original question.

Sorry, my mistake. You want to set `View` to `Details`. Assuming only a single column, you can also set the width of the Column to allow for the vertical scroll bar, getting the scroll bar width using `System.Windows.Forms.SystemInformation.VerticalScrollBarWidth`.

It looks like multiple selection is not supported for the CheckedListBox control (See MSDN). It does support multiple checkboxes being checked, but not multiple items being selected (highlighted) at once.

I agree with the other answer that a ListView is probably the best way to get both checkboxes and multiple selection.

It appears that it it not possible to set see the remarks section in CheckedListBox.SelectionMode Property

For an easier alternative follow the adivice of adrift.
