Centered images in Better ListView

Better ListView 3.11 supports aligning images in sub-items and columns to center. Simply set AlignHorizontalImage property of an sub-item or column to BetterListViewImageAlignmentHorizontal.OverlayCenter.

The image will be centered inside available space regardless of text.

This is useful for sub-items and column headers consisting of image only.

Better ListView Sub-item Check Boxes

Better ListView 3.10.0 allows displaying fully interactive check boxes and even radio buttons in sub-item cells.

This feature can be activated simply by setting CheckBoxAppearance property of a given sub-item to other value than Hide. Such sub-item will not display check box or radio instead of image and text.

Please note the first sub-item’s properties do not apply as they are overriden by item’s properties. These two are separate for the case of column reordering (keeping consistency of sub-item states).

Another new feature in Better ListView is that check boxes or radios can be displayed disabled. This can be achieved by setting CheckEnabled property to false on the respective item or sub-item.

Sub-item check boxes can be operated by both mouse and keyboard. Checking sub-item with keyboard can be done by navigating focus rectangle by arrow keys to the given sub-item and pressing spacebar.

Hiding Column Headers

To hide column headers, simply set HeaderStyle property to BetterListViewHeaderStyle.None. There are other possible styles for all column headers:

• None – column headers are hidden, but corresponding sub-items are still visible
• Nonclickable – column headers are visible, but not interactive
• Clickable – column headers interact with mouse (have hot and pressed state)
• Sortable – column headers are clickable and sort the corresponding column when clicked
• Unsortable – same as Sortable, but the column headers have unsorted state as well
• Hidden – column headers are hidden with corresponding sub-items

These styles can be set on individual column headers as well through BetterListViewColumnHeader.Style property. This property is of type BetterListViewColumnHeaderStyle, which has the same values as BetterListViewHeaderStyle, plus Default value, which means that column header style is inherited from the HeaderStyle property.

When a single column header have style None, that column header is not drawn (only its background is visible) and corresponding sub-items are visible.

When all column headers have style None,  the whole panel with column headers hides (as seen on the above animation) and the sub-items remain visible. This effect is the as when all column headers have style Default and HeaderStyle is set to None.
