The ListView::DrawColumnHeader event is raised by a ListView control when its ListView::OwnerDraw property is set to true and its View property is set to Details. The passed to the event handler contains information about the ColumnHeader to draw and also provides methods to help you draw the header.
Use the Header property to retrieve information about the column header to draw. Use the Graphics property to do the actual drawing within the area specified by the Bounds property. To draw standard ListView elements that do not need customization, use the DrawBackground and DrawText methods.
Use the DrawDefault property when you want the operating system to draw the subitem. This is useful when you want to customize only specific headers.
The following code example demonstrates how to provide custom drawing for a ListView control. The ListView control in the example has a gradient background. Subitems with negative values have a red foreground and a black background.
A handler for the ListView::DrawItem event draws the background for entire items. A handler for the ListView::DrawSubItem event draws the text values and both the text and background for subitems that have negative values. A handler for the DrawColumnHeader event draws each column header.
A ContextMenu component provides a way to switch between the details view and the list view. In the list view, only the ListView::DrawItem event is fired. In this case, the text and background are both drawn in the ListView::DrawItem event handler.
