Examples
The following code example creates a ListView control with three ListViewItem objects specified and three ListViewItem.ListViewSubItem objects specified for each item. The example also creates ColumnHeader objects to display the subitems in details view. Two ImageList objects are also created in the code example to provide images for the ListViewItem objects. These ImageList objects are added to the LargeImageList and SmallImageList properties. The example uses the following properties in creating the ListView control:
This example requires that you have added the code to a Form and call the method created in the example from the constructor or another method on the form. The example also requires that images named MySmallImage1, MySmallImage2, MyLargeImage1, and MyLargeImage2 are located in the root directory of drive C.

Remarks
This version of the Add method allows you to add a subitem to the collection by specifying the text of the subitem. When this method is called, a new ListViewItem.ListViewSubItem is created with the specified text. You can then use the ListViewItem.ListViewSubItem that is returned by this method to set properties and call methods to manipulate the subitem. If you already have an existing ListViewItem.ListViewSubItem that you want to add to the collection, you can use the version of the Add method that accepts a ListViewItem.ListViewSubItem as a parameter, or use the Insert method if you want to add the subitem at a specific position within the collection.

Add(ListViewItem+ListViewSubItem)
Adds an existing ListViewItem.ListViewSubItem to the collection.

The ListViewItem.ListViewSubItem to add to the collection.
Returns
The ListViewItem.ListViewSubItem that was added to the collection.
Remarks
You can use this version of the Add method to add an existing ListViewItem.ListViewSubItem to the collection. This method is typically used to reuse existing subitems from other ListViewItem objects. Items that are added to the collection are inserted at the end of the list. To insert an item into the collection at a specific position, use the Insert method. If you want to add an array of existing ListViewItem.ListViewSubItem objects, you can use the version of the AddRange method that accepts an array of ListViewItem.ListViewSubItem objects as a parameter.

- text
- String
The text to display for the subitem.
Returns
The ListViewItem.ListViewSubItem that was added to the collection.
Remarks
This version of the Add method allows you to add a subitem to the collection by specifying the text of the subitem. In addition, this version of the Add method allows you to specify the initial foreground color, background color, and font of the subitem text. When this method is called, a new ListViewItem.ListViewSubItem is created with the specified text. You can then use the ListViewItem.ListViewSubItem that is returned by this method to set properties and call methods to manipulate the subitem. If you already have an existing ListViewItem.ListViewSubItem that you want to add to the collection, you can use the version of the Add method that accepts a ListViewItem.ListViewSubItem as a parameter, or use the Insert method if you want to add the subitem at a specific position in the collection.
Note
By default, subitems use the foreground color, background color, and font specified for the parent item. Set the ListViewItem.UseItemStyleForSubItems property to false to prevent the parent item styles from overriding the subitem styles.
